INTRODUCTION

Welcome!

Of course we know what you want to do

now. You want to bypass this reference

guide completely and get right into the

business of firing up your new

HUI™. And who wouldn’t? So,

congratulations. You bought

yourself a HUI!

Mackie Designs’ HUI

— Human User Interface

— will make life with

your digital audio

workstation (DAW)

the sweet dream it

was always meant to be.

You’ve always imagined being able to

use your digital audio workstation the way you

use those old analog mixing consoles, but with

the modern enhancements of digital technology.

Now you can.

But before we break on through to the other

side of this page we’d like you to do a few

things:

1. Write down the serial number of your HUI

in the box prepared especially for you on this

page. Keep in mind one of the corollaries to

Murphy’s Law: The very act of writing down the

serial number means you’ll never need to use it.

See? We’re doing you a favor.

2. Check out the “Read Me” file with your

DAW software disks, or any additional inserts

that come with HUI. They’ll contain the lat-

est information about using your HUI,

including software updates, tips and tricks to

help you use it more efficiently, and any other

last-minute changes or addenda to this refer-

ence guide.

3. Save the box and all the foam innards.

Though we expect you’ll never have to send in

your HUI for service (see #1 above), should the

occasion arise you don’t want to be caught with

your pants down. Likewise, we don’t want to

have to sell you new pants (that is, a new box

and innards) to get you through the ordeal.

4. If you can’t force yourself to read this

blessedly short reference guide before digging

in, at least read through the Quick Start section

on pages 8 and 9. This shows you how to con-

nect HUI into your system, so you’re ready to

boldly go where your DAW has only hinted.

Now there’s just one more thing before we

begin…

What This Manual Will Do For You —

And What It Won’t

This reference guide is designed to help you

understand the specific features and controls of

Mackie’s HUI. Since HUI is designed to control

a wide variety of DAWs, including Digidesign®

Pro Tools®, you will want to consult the proper

manual from your particular DAW manufacturer

to understand what each command and control

can do. For example, Pro Tools users should look

in Digidesign’s MIDI Controller’s Guide, or their

Pro Tools owner’s manual for specific information

on how HUI works with Pro Tools.

See the diagram on the next page — it de-

scribes which manual to use and when.

H U I R E F E R E N C E G U I D E

INTENDED USE — WHY HUI?

Take a look at HUI. Lots of buttons, a few

funny-looking knobs, some faders, and a big ol’

jog wheel. If you didn’t know any better you’d

think you’d run across some sort of supersonic

audio mixer. You have — sort of. But HUI is

more than that.

First of all, HUI was designed to work with

digital audio workstations (or DAWs). For pur-

poses of illustration we’re using the Digidesign®

Pro Tools® 4.1 audio hardware/software pack-

age (eventually other DAWs will be compatible

with HUI). As you may well be aware, Pro Tools

allows you to record, edit, mix, and play back

audio in the digital realm. You can make seam-

less electronic edits, EQ changes — basically

anything you’d do in a recording studio — without

affecting the original source material. With your

DAW you can try out infinite possibilities, save

practically infinite versions, and then spend the

rest of your known existence trying to decide

which one was the best. If you make your living

recording and mixing audio for CD, major motion

picture soundtracks, TV/radio audio soundtracks,

or multimedia, a DAW is manna from heaven.

But — and this is a big but — using a mouse

and computer keyboard to do things you used to

do on an analog mixer can be very strange.

Clicking on a visual representation of a fader

and trying to drag the mouse smoothly in order

to achieve an amazing fade-out is difficult, if not

impossible, for many of us. Likewise, turning a

“virtual knob” on a computer screen just doesn’t

cut it for some folks. And that’s why Mackie De-

signs teamed up with Digidesign to create HUI.

HUI gives you hands-on control of all of your

DAW’s parameters. Now you can create a fade

with a real fader. Move a HUI fader and your

DAW “makes note” of your action and mirrors it

on the computer screen. Similarly, when you

make a fader move on your screen, HUI’s fader

moves, too. Adjust EQ by turning one of HUI’s

V-Pot™ knobs and the DAW takes care of the

rest. In fact, mouse-clicking is practically a

thing of the past — with HUI, what used to

take multiple mouse-clicks and key combinations

can now be accomplished with the push of a

button or two. You can use HUI’s hands-on

controls to do everything from recording a single

track to grouping multiple tracks, assigning in-

serts and aux sends/returns, automating mixes,

and mixing programs for surround-sound.

Touch-updatable moving faders, V-Pots, elec-

tronic “scribble strips,” a 40 by two-character

display, built-in meter bridge, and an ergonomi-

cally laid-out control surface make HUI the

logical choice for returning analog-style control

to your digital world.

The built-in control room section provides a

convenient way to monitor your mixes without

having to use a separate mixer. It has three

stereo inputs and three stereo outputs, plus a

headphone output. The monitor inputs can be

mixed together, or they can remain discrete,

direct assigned to their corresponding monitor

outputs.

For additional tracking capability, we added

two of our handy studio grade microphone

preamps for direct analog connection to your

digital audio interface’s A/D converters. These

mic pre’s are the same design as those on our

large format recording consoles, and offer

plenty of gain, insert patching, and phantom

power for condenser mics. You can use them for

recording any sound source with low noise, low

distortion, and wide frequency response. To top

it off, we added a third mic preamp for a remote

producer talkback mic or slating capabilities.

You can do so much with HUI. It’s a mix con-

trol surface that sets new levels of interactivity

within today’s and tomorrow’s DAW environ-

ments — it will grow with your system, DAW

software upgrades, etc. HUI can greatly improve

your creativity while diminishing your workload

and the repetitive grind of multiple sessions.

INTENDED USE — WHY HUI?

H U I R E F E R E N C E G U I D E

HUI Does What Your DAW Does

Though HUI can do many things, there are

some things it cannot do. If your DAW software

can’t do a particular magic audio trick you’ve

always wished for, neither can HUI*. Because

HUI works along with your DAW — thanks to

the software and MIDI instructions that go

back and forth between HUI and your computer

— it is at your software’s mercy. This is a good

thing, though. If your DAW software is updated

with new features or what have you, HUI can

keep up with the technology. So, though your

software may change, HUI will stay the same.

It’ll let you control your DAW with the hands-

on ease and intuition you expect. It lets you be

as creative as you want to be.

One caveat: Some DAW software packages

accept third party plug-ins. It’s up to the plug-in

designer to insure that their plug-in works cor-

rectly with external controllers like HUI.

HUI SELF-DEMO

Perform the Self-Demo (Optional)

Before you go all the way and connect HUI in

your studio, you can perform this self-demo to

make sure it lights up and works properly, and

to get an idea of what HUI can do.

We’re new-technology fiends just like you are

— we know you want to impress people with

your wise purchase. So set up your HUI on a

tabletop or other such eye-level resting place and

call in the kids, the other studio engineers, or

anyone within shouting distance. We’re going to

plug it in, turn it on, and MAKE IT LIGHT UP!

Just follow these simple directions, okay?

1. With HUI out of the box and propped up

for all to admire, grab the power cord and plug

it in. (Don’t turn it on yet.) We recommend us-

ing a UPS or circuit-protected outlet strip like

the kind you use with your computer or other

audio hardware.

2. Turn on HUI by pressing the rocker

POWER

switch on the rear panel.

3. Within three seconds after turning on the

power, simultaneously press the

CTRL

and

ALT

buttons (located in the “Keyboard Shortcuts”

section at the lower left area of HUI’s front

panel). The self-demo begins, and will continue

as long as HUI is powered up.

Note: You can quit the self-demo at any time

by simply turning off HUI’s

POWER

switch.

HUI SELF-DEMO

* That’s why we didn’t name it “Harry HUIdini.”

An Installation Note

HUI has conductive knobs on the faders that

can “sense” when you touch them and toggle

the “Write” mode for those channels automati-

cally. Furthermore, as soon as you let go of the

knob, the channel goes back into playback

mode, playing back whatever automation had

been previously recorded.

The touch circuits operate by sensing the

stray capacitance your body provides between

the fader knobs and ground. There are a num-

ber of variables that can affect the operation of

this circuit, including temperature, humidity,

and the number of fader knobs touched.

Reliable operation of the touch circuits de-

pends on providing a good earth ground for the

HUI. Be sure the power cord is plugged into a

3-prong outlet with the third pin (safety pin)

connected to earth ground. If you’re not sure

whether the third pin is grounded, use an AC

outlet circuit tester to verify that the outlet is

properly configured (available from Radio

Shack and many fine hardware stores).

DO NOT BYPASS THE SAFETY PIN ON

THE PLUG.

QUICK START

Okay, okay… let’s run some audio through

HUI’s monitor section. If you already performed

the self-demo, then you know the faders work.

The next logical stage is to make sure that HUI

works with audio connected, and with your DAW.

Quick Start Audio Test

The diagram below shows the simple audio

connections you’ll need to make for the audio

quick start.

1. With HUI’s power turned off, plug in one of

the following:

• A pair of powered studio monitors to

MONI-

TOR OUTPUTS 1

on HUI’s rear panel; or…

• A pair of speakers (via a power amp) to

MONITOR OUTPUTS 1

on HUI’s rear panel;

or…

• At the very least, a pair of headphones. You’ll

plug these into — wonder of all wonders —

the

HEADPHONES

jack on HUI’s rear panel.

Now you can hear what’s happening.

2. Connect the output of a stereo audio

source (e.g., tape deck or CD player) to the

L/R

MONITOR INPUTS 1

3. Make sure the front panel

MASTER VOL-

UME

and

LEVEL

knobs are off or turned down.

4. Power up HUI by pressing the

POWER

switch on the rear panel.

5. On HUI’s front panel, make sure the

INPUT 1

OUTPUT 1

and

OUTPUT 3

buttons are pressed.

They’re in the

CONTROL ROOM

section; their

LEDs will light up. (Be sure the

1:1 DISCRETE

switch is off.)

6. Turn up the

MASTER VOLUME

knob, the

LEVEL 1

knob, and the

LEVEL 3

knob enough

to hear sound coming from the speakers and

headphones.

7. Set the

TALKBACK MIC

switch on the

rear panel to the

INTERNAL

position. With the

TALKBACK LEVEL

knob all the way down,

press and hold the

TALKBACK

button, and

slowly turn the

TALKBACK LEVEL

knob up un-

til you can hear yourself talk in the

headphones.

Note:

TALKBACK

is only assigned to

OUT-

PUT 3/PHONES

from the factory. You can

assign

TALKBACK

to any of the

OUTPUTS

(see instructions under “Talkback Section” on

page 13).

8. Repatch the audio source into various in-

puts and turn on the various front panel input

and output switches accordingly. As a precau-

tion, turn down the

MASTER VOLUME

control while repatching cables. You’re now

checking all of the various input and output

combinations.

More information on HUI inputs and outputs

can be found in the “Audio Input and Output”

section, which begins on page 17.

If you suspect a problem with the HUI, turn

to the “Troubleshooting” section beginning on

page 25 and run the self-test.

QUICK START

H U I R E F E R E N C E G U I D E

Quick Start DAW Controller Test

In order to make sure HUI is working in con-

junction with your DAW, we’ll perform the next

test. However, a few things need to be set prop-

erly in your system software on your computer:

• Hook up your computer to HUI as shown in

the diagram below.

• Make sure you have OMS (Open Music Sys-

tem) installed (or whatever MIDI software is

compatible with your DAW), active, and

properly configured on your computer.

• Make sure HUI is defined as a device in your

OMS setup (be sure the proper port, chan-

nels, etc., are selected).

Note: Consult your software manual (or

OMS literature) for the specifics on the above-

mentioned OMS-related steps.

• Make sure the interface hardware is turned

on, and the MIDI cables are properly routed

in and out according to the port configura-

tions defined in the MIDI system software

(i.e., OMS).

•Pro Tools Users: Make sure the HUI “per-

sonality file” is placed in the DAE controller

folder in your System folder, and check the

Pro Tools MIDI Controller’s Guide for informa-

tion on OMS setup.

• Make sure HUI is defined as a MIDI control-

ler peripheral in your DAW software.

1. Run a pair of audio cables from your DAW

audio interface’s outputs to HUI’s

MONITOR

INPUTS 1

(L & R). The plugs on these cables

will depend on what type of jacks (1/4″, RCA,

XLR) you have on your DAW audio interface or

sound card; the HUI ends of these cables

should be 1/4″ TRS plugs (TS are okay).

2. You’ll need a previously-recorded session

to demo. Chances are you’ve either already re-

corded some sessions with your DAW and can

use one of those. If you have no session to call

your own, the software CD-ROM should have a

sample session for you to use.

With all the above connections made and

your DAW turned on:

3. Switch on HUI with the

POWER

switch

on the rear panel. Turn on the power amps or

powered monitors last.

4. Start your DAW application.

5. As soon as HUI is defined as a peripheral,

MIDI active sensing is enabled and HUI begins

displaying time code. This is a good thing.

6. Press HUI’s

PLAY

button. (You could also

click on PLAY on your computer screen, but

since we’re testing HUI…). The time code will

change, indicating success.

7. Enable the control room inputs and outputs,

turn up the volume, and dance to the music.

NOTE: The functions of some of these switches

depend on your particular DAW software. There-

fore, you may wish to consult your DAW manual

for further details.

1 Rec/Rdy (Record/Ready) switch. This

switch arms or disables the channel for recording.

2 Insert switch. This switch calls up inserts

for editing, and also allows you to bypass all in-

serts on the channel when the master

BYPASS

switch is pressed (see bo at right). Makes it easy

to access DSP (digital signal processing) soft-

ware additions. (In Pro Tools these are called

Plug-Ins.)

3 V-Sel switch. This switch toggles be-

tween the various functions of the

V-Pot, such as I/O routing assign-

ment, Send Mute switching (when

the master

MUTE

switch is en-

gaged), and Select when applying

the default function.

4 Pan/Send V-Pot™. This

“soft” potentiometer is used to

adjust the send level and pan, to

choose items from scrollable I/O

assignment lists, and to deter-

mine destinations for sends.

5 Auto switch. For enabling

automation on the channel.

6 Solo switch. For isolating

a channel’s signal.

7 Mute switch. For defeat-

ing the track’s signal.

8 Scribble strip. A four-

character LED dot-matrix display

for the channel’s name, group

membership status, input and

output source for the channel,

send and insert status, and pre/

post status display for sends.

Names are entered in the DAW

software.

9 Select switch. This switch

is used to choose a channel for

channel-based editing or assign-

ment commands, such as groups,

assignment, etc.

bl Touch-sensitive motor

faders. These 100mm faders are

for controlling the channel’s lev-

els, aux returns, MIDI track, and

master fader levels. The eight

faders move relative to the activ-

ity of the currently chosen bank

of on-screen faders.

bm Dual LED ladders. (Not shown here.)

Display mono or stereo audio levels, according

to the DAW specifications. The Clip LED comes

on at 0dBFS.

For Pro Tools users: When a channel is desig-

nated as mono, only the left meter ladder lights

up. Likewise, if the channel is being used as a

stereo channel, both ladders operate. (These

meters are located in the meter bridge directly

above each channel strip.)

Left Control Strip

bn Rec/Rdy All switch. This switch is used

to enable (or defeat) all tracks for recording.

bo Bypass switch. This switch allows you

to bypass any channel inserts (hardware or

DSP Plug-Ins) on any HUI channel(s) you have

selected.

bp Select/Assign

switches and scribble

strip. These switches are

used to globally deter-

mine what a track’s V-Pot

will control. Included in

this section are:

SENDS

A–E

Display blinks (once per second). If incoming

MIDI communication is disrupted for any reason,

the Time Code Display will read “Off Line.”

7 Rude Solo Light. A gentle reminder that

a channel (or channels) in your mix session is

soloed, whether it’s part of the current bank of

eight channels or not.

8 Locate/Numerics keypad. Equivalent to

its computer keyboard counterpart.

Control Room Section

The features found in this parcel of real es-

tate (pictured on the next page) were included to

let you use HUI without having to dedicate a

mixer to monitoring functions. You can control

input and output sources, as well as master

volume, from this section. With the talkback

features you can slate takes or talk to the voice

talent, either with the in-panel talkback mic or

with an external mic plugged into HUI’s back-

side. We’re sure you’ll find these features quite

useful in your daily DAW work. (See page 18

to the

MONITOR INPUTS 1, 2, and 3

jacks on

HUI’s rear panel.

2 1:1 Discrete switch. This switch deter-

mines whether HUI’s inputs act as three stereo

pairs assignable to any stereo output, or as six

discrete mono inputs assigned to their corre-

sponding outputs only (used for

surround-sound mixing).

3 Mono switch. When this switch is en-

gaged, HUI sums all signals through the

MASTER VOLUME

control into one mono signal.

4 Master Volume control. This level con-

trol determines the overall level of the currently

selected monitor source(s).

5 Output level controls. Each one of these

controls adjusts the output level of its respec-

tive audio output pair.

6 Output select switches. These switches

determine which monitor outputs are being

used. Labeled

Rear Panel

Controller Input/Output Section

1 Power cord receptacle and Power

switch. The power cord receptacle is a stan-

dard IEC connection for HUI’s power cord.

Before plugging the power cord into an AC out-

let, be sure it is firmly seated in the receptacle.

Note: For safety reasons, the AC outlet must

be a “3-prong” outlet with hot, neutral, and

ground terminals. Do not bypass the plug’s

ground pin! In addition to the safety issue, this

insures that the HUI’s chassis is properly

grounded which is required for reliable opera-

tion of the faders’ touch circuits.

2 MIDI In/Out Connectors. These are

standard MIDI 5-pin DIN ports for connecting

HUI to your MIDI interface. (Note: HUI must be

connected to a dedicated MIDI input and out-

put pair; these connectors cannot be merged or

daisy-chained.)

3 Keyboard/Mouse ADB ports. Conve-

nient in/out throughput jacks for direct parallel

connection of your ADB (Apple Desktop Bus)

computer keyboard and mouse. These are used

for extending the reach of your keyboard and

mouse between your computer and HUI, not for

actual control. See page 19 for more information.

4 Serial port, RS-232/422 switch. The

serial port is a standard 9-pin D-Sub connector

for connecting HUI to the external DAW. The

switch selects between RS-232 and RS-422

operation (the data stream is equivalent to MIDI).

See page 19 and page 31 for pin out and other

specifications.

5 Expansion Port. 9-pin D-Sub connector for

future connection of external control devices.

6 Footswitch Input jacks. Allows you to use

an external footswitch to toggle DAW functions

such as loop, play, and record modes.

7 Relay Output jacks. Used to toggle ex-

ternal circuits for solo indication, “on-air”

lights, recording lights, etc. See page 31 in the

“Specifications” section for a block diagram of

these jacks.

Analog Audio Input/Output Section

8 Monitor Inputs (x3). These six line-

level inputs (balanced or unbalanced) feed the

as three stereo pairs or as six discrete inputs.

9 Monitor Outputs (x3). These six line-

level outputs (balanced or unbalanced) from the

control room section can be used either as three

Talkback and Mic Preamp

Section

Another great thing about HUI —

if we don’t mind saying so our-

selves — is its talkback and mic

preamps. They allow you to add

a vocal track, insert slating in-

structions, and perform other

handy tasks, without having to

resort to an outboard mixer.

1 Mic preamp Trim control.

Used to set initial gain stage for

mic signal levels (Mic 1, Mic 2,

and Talkback). Trim level from

mic level (60dB down) to Unity

(0dBu). Maximum input is +22dBu.

2 Phantom Power switch.

Push this switch to provide 48V

of low-current DC to power

condenser mics.

3 Talkback XLR mic input.

Used to connect an external talk-

back mic. Note that there is no

dedicated output for this preamp,

although talkback logic routing

will send the signal to any or all of

the

MONITOR OUTPUTS

(front

panel assignable — see instructions

for the Talkback Enable switch bl

on page 13).

4 Mic Internal/External switch. Switches

talkback signal source between the front in-panel

mic or an external talkback mic plugged in here.

5 Remote Talkback Trigger jack. The

talkback circuit is bidirectional — it can either

trigger something or be triggered by something.

To remotely trigger HUI’s talkback function, con-

nect a normally-open on/off footswitch to this jack.

This is for the producer who loves to sit com-

fortably back and communicate with the talent

during crucial moments in a recording session.

Conversely, if the engineer wants to enable

another console’s talkback function via the HUI

front panel talkback switch, connect a TS cable

between this jack and an unbalanced destina-

tion jack. When the front panel talkback switch

is pressed (enabled), the line is pulled “low.”

See page 31 for a diagram of this circuit.

6 XLR mic inputs. These are two of

Mackie’s high-headroom, low-noise mic

preamps. Intended for mic-level inputs only,

they offer plenty of gain and sonic clarity.

7 Inserts. 1/4″ TRS insert jacks for using

in-line external effects and signal processing

with TRS to TS send and TS return “Y” cables.

These connectors can also be used as direct

outputs using a 1/4″ TS plug pushed in all the

way (interrupting the audio signal completely),

or only to the first click, which does not inter-

rupt the audio (see “Insert Jack Options”

figure). The latter method allows you to use the

insert as a direct out in combination with the

mic output described next.

8 Outputs. 1/4″ TRS jacks for routing your

microphones to external sources, such as the

DAW audio interface for recording. These line-

level outputs will provide either balanced and

unbalanced signals.

AUDIO INPUT AND OUTPUT

Signal Flow Primer

Monitoring the audio signals can be done in

either mono, stereo, or surround-sound (with

six discrete channels). The overall input vol-

ume is controlled by the

MASTER VOLUME

knob. The outputs are controlled by three sepa-

rate output level controls and toggle switches

(labeled

OUTPUT 1, 2,

and

). HUI uses DCAs

(digitally controlled amplifiers) to control in-

ternal signal flow completely independent of

the DAW. The signal is distributed according to

which inputs and outputs are enabled.

Stereo Monitor Mode — enabled inputs’ stereo

signals are

summed

into one stereo signal

In stereo monitor mode — with the

1:1 DIS-

CRETE

switch turned off — any of the three

stereo input sources may feed any of the stereo

MONITOR OUTPUTS

(

OUTPUT 1, 2, and 3

Any or all of the three stereo inputs can be

monitored simultaneously. That is, it’s up to you

to disengage an input if you don’t want to moni-

tor it. Any and all of the

OUTPUTS

can be

active at once, so you can send outputs to vari-

ous pairs of speakers and various combinations

of speaker pairs and recorders.

AUDIO INPUT AND OUTPUT

1:1 Discrete Monitor Mode — enabled inputs are

not

summed

When HUI’s

1:1 DISCRETE

switch is engaged

(the LED will light), the control room section be-

comes a discrete surround matrix capable of

either standard 4.1 surround (L/R/Center/Sur-

round/subwoofer), or 5.1 surround (L/R/Center/

Surround L/Surround R/subwoofer).

You can set up your DAW audio output con-

figuration so that the various “stem” outputs

correspond to the physical outputs on the DAW

audio interface. These outputs are then patched

to HUI’s

MONITOR INPUTS 1, 2, and 3

With

1:1 DISCRETE

engaged, the output

LEVEL

controls for

OUTPUTS 1, 2, and 3

act as

trims for the respective mix stems (L/R/Center/

Surround L/Surround R/subwoofer). The

MAS-

TER VOLUME

controls the level for all three

output pairs, allowing you to trim the overall

level of separate surround amp feeds.

Keep in mind that, when in discrete mode,

output pairs share a common stereo level con-

trol and individual outputs cannot be adjusted

independently.

Note: The

DIM

and

MUTE

controls operate

on all outputs, regardless of whether HUI is in

discrete mode.

MONO

, too, sums all inputs to-

gether, regardless of mode. Refer to the audio

block diagram on page 30 for further info.

to run your quality mics through second-rate

preamps, we use preamps with large-emitter-ge-

ometry, conjugate-pair transistors, allowing them

to sound as good as the preamps on the most

expensive consoles.

Connect your mics to the HUI preamps by

using an appropriate cable with XLR connec-

tors. (Pin 1=Shield [Ground], Pin 2=Signal

High [+], Pin 3=Signal Low [–].)

Adjusting the Mic Trim Control

To get the best signal-to-noise ratio, it is im-

portant to set the

MIC TRIM

controls properly.

1. Connect the microphone to the

MIC IN-

PUT

connector. Push in the

+48V PHANTOM

switch if required for your microphone.

2. Turn the

TRIM

level control all the way

down (counterclockwise).

3. Disconnect any external gear connected

to the

INSERT

jack.

4. Connect the

BAL/UNBAL OUT

connector

to the input of the DAW audio interface. En-

gage the Rec/Rdy function on that channel,

and set its input level to unity gain.

5. Make appropriate “noise” into the micro-

phone. For example, have a performer play/

sing/strike something or someone, etc. at the

level they’re going to record or perform. Don’t just

play a single sustained note, but rather, jam away

as you would during a recording or performance.

You might want to roll an already-recorded

track from your recorder.

6. Adjust the

TRIM

level control. The goal is

to produce the highest signal level possible

without distorting the mic preamp stage, and

to attain the highest bit level when the analog

signal is converted to digital, without exceed-

ing the maximum digital value (which results

in digital clipping). As a general rule, you want

the meter on the DAW audio interface to read at

or around –15 dB. The peaks should regularly

hit, and occasionally exceed, the –15 dB desig-

nation on the meter.

7. If you connect an external processor to

the INSERT jack, you may need to readjust the

input level control for the DAW audio interface.

Talkback Mic

Though HUI has its own talkback mic on the

front panel, you may want to connect an exter-

nal talkback mic of your own. That’s why we’ve

included a talkback mic preamp on the rear

panel. This mic preamp is identical to the other

two mic preamps (described above), giving you a

total of three high-quality mic inputs. Connect

your external talkback mic the same way you

would the other mics. Be sure the talkback

TRIM

control is turned up (adjust to taste).

The

MIC INTERNAL/EXTERNAL

switch on

HUI’s rear panel lets you choose between the

front in-panel mic or an external talkback mic.

Be sure it is switched according to your needs.

Monitor Outputs

To connect studio monitors (like a pair of

Mackie’s HR824s) to HUI, simply connect one

end of your cables (with 1/4″ TRS plugs) into

MONITOR OUTPUT 1

(the left one is for Left

speaker or mono output; right is for Right

speaker output), and the other ends to your

studio monitors.

HUI features three pairs of monitor output

jacks, so you can run up to three sets of monitors

at one time. You may have one set of monitors

in your control room, and one or two others

running to various other places like vocal

booths or the like. Or you may want to audition

your mixes through three different types of

speakers (monitors).

H U I R E F E R E N C E G U I D E

DIGITAL CONNECTIONS

These outputs are designed for monitoring

purposes. We do not recommend mixing through

this output section due to the possibility of

feedback routing, and to the fact that smooth

fades, if applicable, may experience some “zip-

pering” inherent to digitally controlled amplifiers

(DCAs). Although these are high quality DCAs,

they are not volume smoothed (interpolated)

between their discrete volume levels. The volume

taper is mapped to resemble the taper of our

analog mixer rotary pots.

DIGITAL CONNECTIONS

MIDI

In order to operate, HUI must be connected

to a MIDI interface. The MIDI interface is in

turn connected to the external computer used

with your DAW.

Connect HUI to a MIDI interface by connect-

ing one MIDI cable between HUI’s

MIDI IN

port and the interface’s MIDI OUT port. Like-

wise, the other cable should be connected

between HUI’s

MIDI OUT

port and the

interface’s MIDI IN port. Now HUI and your

MIDI interface can talk to each other, compare

recipes, and share football scores.

RS-232/RS-422 Serial Port

To use HUI in conjunction with a computer,

run a cable with a 9-pin D-Sub connector from

HUI’s

SERIAL PORT

to the computer’s COM port.

The serial port on HUI bidirectionally trans-

fers data between a computer’s RS-232 or

RS-422 serial port and HUI. The only difference

between using the

SERIAL

and

MIDI

ports is the

rate of transmission of the data (the serial port

operates at 38.4K Baud and MIDI operates at

31.25K Baud) and the general physical hard-

ware (9-pin D-Sub vs. 5-pin DIN, respectively).

The actual data transferred is the same.

For RS-232: Pin 2=TXD

Pin 3=RXD

Pin 5=Ground

For RS-422: Pin 2=TX–

Pin 3=RX+

Pin 4=Ground

Pin 7 =TX+

Pin 8=RX–

Use the following serial communications

parameters when using the

SERIAL

port:

Baud rate: 38.4K

Parity: None

Data bits: 8

Stop bits: 1

Keyboard (computer)

You can “extend ” the use of your computer’s

keyboard by connecting the keyboard to HUI.

Simply connect a 4-pin ADB cable from your

keyboard to HUI’s

KEYBOARD IN

jack. Run

another 4-pin ADB cable from your computer to

HUI’s

KEYBOARD THRU

jack. Now your key-

board can be in closer proximity to HUI.

Note: This extra feature is not required in

order to use HUI — it is there as a convenience

to those who may need the extra length. The

ADB specification limits the ADB cable length

to 5 meters (about 16 feet).

Mouse

Similarly, you can extend the use of your

mouse (or trackball if you’re supremely cool) by

connecting it to HUI. Although most Apple

computers allow you to connect the mouse di-

rectly to the keyboard, some models have more

than one ADB connector on the computer. Using

a 4-pin ADB cable, connect one end to your com-

puter and the other to HUI’s

MOUSE THRU

jack. Then run another 4-pin ADB cable from

HUI’s

MOUSE IN

jack to your mouse or

trackball. (You’ll probably be using the cable

that is hardwired to your mouse — if you use a

trackball you’ll need a separate cable.)

You can use the MOUSE I/O to extend a sec-

ond keyboard/mouse to another computer,

which you might use for sequencing or some

other purpose.

A note regarding ADB port and MIDI com-

munication: HUI communicates with the host

DAW through the MIDI IN/OUT connectors.

The mouse and computer keyboard communi-

cate with the DAW through the ADB connectors.

The Mouse and Keyboard IN/OUT connectors

are wired straight-through, so there is no direct

interaction with the HUI, MIDI or SERIAL ports.

Even though both the HUI and the computer

keyboard have common modifier switches such

as SHIFT, OPTION, ALT, CONTROL, F-keys,

etc., the DAW determines how these keys oper-

ate and interact with one another. For example,

pressing the SHIFT/ADD button on the HUI in

conjunction with a mouse click may not work

the same as pressing the SHIFT key on the

keyboard in conjunction with a mouse click.

Expansion Port

This port is nestled on HUI’s backside for

use with future products.

TV/Radio Production Hookup

APPLICATION HOOKUPS

Some Application Basics

One of the first things to consider when con-

figuring your studio with HUI is what type of

application suits you best. If you produce com-

mercials for TV or radio, the TV/Radio

Production Hookup may be your best bet. If

you record and mix soundtracks for surround

sound, you’ll probably set up your studio simi-

lar to our Surround Sound Hookup.

One thing is certain: you’ll want to position

HUI in a place central to your work area.

It should be close enough to your com-

puter, studio monitors, and of course

mixer, to facilitate easy, ergonomic use. If

you have your computer in an out-of-the-

way location (on the floor behind the

console; in an hermetically-sealed coffin

six feet under), you’ll want to run your

computer keyboard and mouse connec-

tions from your computer to HUI. You

can then use HUI’s

KEYBOARD IN

and

MOUSE IN

jacks to place the keyboard

and mouse in close proximity to HUI and

your mixer. (See “Digital Connections”

Section, page 19, for more details.)

What follows are a few sample hook-

ups. Each one shows you a basic setup,

lists the equipment you’ll need, and gives

a few tips and/or insights. Of course, your

HUI hookup may be a variation on one of

these themes — these are just sugges-

tions, so see what you come up with.

TV/Radio Production Hookup

Scenario: Broadcast, multimedia. audio-

for-video suite, production.

Source Material: Prerecorded sound

files, music, voiceovers, sound effects,

compact disc, videotape, etc.

Outputs: One or more speaker pairs,

headphones, mixdown deck (cassette or

DAT).

Audio Hookup: Multiple stereo

sources into the inputs. The DAW interface or

soundcard can play back prerecorded material

in playlist or some other composite fashion.

The CD and DAT are for A–B playback com-

parison purposes, extra material, sound check,

test tones, etc. The DAT output feeding HUI

INPUT 3

may be the one master deck that is

being mixed to from HUI

OUTPUT 3

. (Be care-

ful of feedback loops while recording!)

Digital Control Hookup: MIDI I/O for HUI to

the computer/DAW.

Special Notes: To avoid feedback during

tracking, do not feed outputs to record-engaged

inputs of the same device.

APPLICATION HOOKUPS

Tracking/Mixing Hookup

Scenario: Broadcast, multimedia, audio-for-

video suite, production, home studio recording,

mixdown, playback.

Source Material: Live audio (vocals, guitars,

dog, etc.), samplers, synths, drum machines,

prerecorded tracks.

Outputs: To DAW interface, mixdown deck,

speaker pair(s), headphones, effects loop from

inserts.

Audio Hookup:

Use Stereo Monitor Mode.

Tracking: One or two mics are plugged into

HUI’s excellent mic preamps (guitar/vocal, vocal

duo, etc.). A stereo compressor/limiter is inline

using the insert (compressor/limiter separated

as two mono units). The mic’s line output is

routed to the DAW audio interface either directly

or through a microphone mixer.

Overdubbing: Accomplished by recording

newly-enabled DAW tracks while monitoring

DAW output of previously laid-down tracks

through HUI

MONITOR INPUT 3

. The DAT/

HUI hookup (

MONITOR OUTPUT 2

) is for fi-

nal mastering tasks.

Mixdown: After you’ve recorded all the tracks

on the DAW, it’s time to automate the mixdown.

Follow your DAW’s instructions on creating and

automating a session.

MONITOR OUTPUT 3

is used for monitor speakers. When you finally

have it right, simply run the session one last time

with the DAT deck in record mode and its inputs

connected to HUI’s

MONITOR OUTPUT 2.

Digital Control Hookup: Connect MIDI I/O

from HUI to the computer/DAW. Any other

sources that might need to be synchronized to

the DAW are totally optional and studio-specific.

Special Notes: Use the

MONO

button in

the Control Room section to determine phase

cancellation during recording (i.e. mics cancel-

ling out each other).

MONO

is also a useful

check for stereo material that is to be aired for

mono broadcast (again, as a level balance and

phase cancellation check).

Surround-Sound Hookup

(5.1 configuration shown)

Surround-Sound Hookup

Scenario: Film, DVD, home theater mixing.

Source Material: Dialog, sound effects, mu-

sic, ambience stems, Foley, etc.

Outputs: As above.

Audio Hookup: To patchbay and HUI.

For monitoring when recording or mixing for

surround-sound, we suggest the following dis-

crete signal arrangements. Of course, using a

half-normalled or multed patchbay to simulta-

neously feed the signals to the final mix

recording deck and to HUI (for monitoring)

would make life much easier. Consult your fa-

vorite pro audio or music dealer for more

information on patchbays.

Be sure the 1:1 DISCRETE button is

switched on for the following applications.

For 5.1 Surround-Sound

On HUI’s rear panel, connect your DAW audio

interface outputs to:

Input 1 = L/R inputs

Input 2 = L/R Surround inputs

Input 3 = Center/Subwoofer inputs

Output assignments (to control room amplifi-

ers) would follow the same basic signal routing

paths.

For 4.1 Surround-Sound

On HUI’s rear panel, connect your DAW audio

interface outputs to:

Input 1 = L/R inputs

Input 2 = Center/Mono surround inputs

Input 3 = Subwoofer

Output assignments (to control room amplifi-

ers) would follow the same basic signal routing

paths.

Digital Control Hookup: Studio sync as ap-

plicable.

Full-On Major League Hookup

Scenario: Any audio application with a

plethora of inputs to stereo final master. HUI is

the control room hub, so the mains or control

room outputs of the mixer and DAW feed HUI.

Source Material: Live audio, synths, sam-

plers, multitracks, DAW tracks, etc.

Outputs: HUI’s

OUTPUT 1

is fed to a head-

phone amp/mixer for further distribution to

multiple headphone pairs.

OUTPUT 2

goes to

a dubbing or mastering deck.

OUTPUT 3

routed to a speaker selector box so multiple

speaker pairs can be used.

Audio Hookup:

Tracking: Normally, live audio goes either to

tape or hard disk, while MIDI-sequenced

synth, samplers, etc. are used to play against

during overdub or as final mixdown “virtual”

tracks. Virtual tracks are good for saving tape

and hard disk space, and avoiding added noise

through additional audio transfer and tracking.

• The mixer mains, the mastering deck, and

the DAW feed HUI’s inputs, for control room

monitoring purposes.

• The mixer aux sends, DAW aux send buses

(available in Pro Tools 4.1, for example), and

HUI

OUTPUT 1

feed the external head-

phone mixer — all for extra and/or remote

monitoring purposes.

• HUI

OUTPUT 3

feeds a speaker selector for

A/B comparison of big vs. small speakers,

mono level-balancing, etc.

• Mics are used as: direct-to-DAW feeds for

boosting signals to line level, or as extra mic

preamps to feed line inputs on the mixer.

• The engineer’s talkback mic is set to feed all

of the monitor outputs.

• A stereo compressor/limiter feeds the in-

serts as two mono compressor/limiter units.

Digital Control Hookup: HUI MIDI I/O, as

well as MIDI sync and triggering to all instru-

ments to sync with digital audio from the DAW.

Special Notes: Use the

MONO

button in the

Control Room section to determine phase cancel-

lation during recording (i.e., mics cancelling out

each other).

TROUBLESHOOTING

Having trouble getting things to “cooper-

ate”? Consult the Troubleshooting chart on this

page. It should point you in the general direc-

tion of things to check, etc. Then proceed to

the following pages to help you narrow down

the problem. If you believe the problem is HUI

related, see the Service section on page 27.

Perform a HUI Hardware Self-Test

HUI has a built-in self-test routine which

can help you determine if the problem you’re

experiencing is HUI related or not. You need

the following items to perform the self-test:

• One standard MIDI cable

• Two normally-open footswitches (or two

1/4” plugs or patch cords with tip

shorted to sleeve)

1. Connect a MIDI cable from

HUI’s

MIDI OUT

jack to HUI’s

MIDI

jack. This allows HUI to run the

test and then loop the information

back to itself.

2. Connect a normally-open foot-

switch to each of the

FOOTSWITCH

jacks.

3. Plug the power cord into a 3-

prong AC outlet, that you know has a

good safety ground. (You might want

to test the outlet with an AC outlet

tester. You can get one at Radio Shack

or most hardware stores.)

4. Turn on HUI by pressing the

POWER

switch on the rear panel.

5. Within three seconds after turn-

ing on the power, simultaneously

press the

SHIFT

and

OPTION

but-

tons (located in the “Keyboard

Shortcuts” section at the lower left

area of HUI’s front panel). You will

see the 40x2 character VFD on the

front panel light up and it will prompt

you with the instructions to complete

the self-test.

Note: You can quit the self-test at

any time by simply turning off HUI’s

Power switch.

Be sure to follow the instructions

displayed in the VFD completely. You

want to be sure HUI is ready to roll

when you’ve finished this test.

6. Use the footswitch to step

through the self-test. By now you

may be thinking, “Why is it called a

‘self-test’ when I have to help it

along?” It’s because we thought

“Human-Assisted Semi-Self-Test”

was practically an oxymoron, not to

mention being a bit long.

Audio

If you’re having trouble getting audio through

HUI, check the following:

General

• Say, uhhh, is the

POWER

switch turned on?

Sorry—gotta ask.

• Have you tried re-booting HUI by turning it

off, waiting a few seconds, and then turning

it back on again? Sometimes this can help

alleviate the little burps and hiccups that

can occur. (Be sure to turn down the volume

on any connected power amps first BEFORE

re-booting.)

H U I R E F E R E N C E G U I D E

Bad Input

• Is an

INPUT

assigned for output to a con-

nected output device? (i.e., speakers or

head- phones)

• Is the proper

FADER

up? Is the proper

FADER

assigned?

• Try unplugging any insert devices from the

INSERT

jacks.

• Make sure anything plugged into an

INSERT

is plugged in correctly (i.e., to first click or

second click, depending on what type of

plugs you’re using).

• Is the

MASTER VOLUME

turned up?

• Are the input and output assignments set

correctly?

• Try the same source signal in another

INPUT

, set up exactly like the suspect input.

Bad Output

• Are any of the MUTE switches turned on?

• Is an

OUTPUT

selected?

• Is HUI connected to your studio monitors or

other such speakers?

• Check your cables to make sure they’re all

working properly.

• Try multiple source and destination substi-

tutes.

• Check your signal flow and gain staging.

Note: The

LEVEL

controls for the

MONI-

TOR OUTPUTS

use high-quality DCAs

(Digitally Controlled Amplifiers). Due to the

discrete nature of a DCA, if you change the

level quickly you may perceive a “zippering”

effect as the volume ramps up or down. This is

normal, and should not present a problem for

normal monitoring purposes.

Fader Touch-Circuits

The fader’s touch-circuits are designed to

disengage the fader motor as soon as you touch

the fader knob. When you release the knob,

HUI again takes control over the fader (motor

engages).

The fader knob is electrically conductive,

and when your finger touches the knob, HUI

senses your touch and sends a message to the

DAW through the MIDI connection. The DAW

reacts by sending a message back to the HUI

to disengage the motor. You can observe the

MIDI port IN and OUT LEDs blink on the MIDI

interface when you touch a fader.

When you release the fader, HUI sends an-

other message to the DAW, via MIDI.

Depending on how the DAW is configured for

that channel, it may send a message back to

HUI to turn on the fader motor. Again, you can

observe the MIDI message activity by watching

the MIDI interface I/O LEDs blink.

If the motors continue to operate when you

touch the knobs, HUI may not be properly

grounded.

• Make sure the AC linecord is plugged into a

“3-prong” outlet. The outlet should be prop-

erly wired and grounded. If you’re not sure,

test it with a three-wire AC outlet tester,

available at most fine hardware stores or

electronics supply shops. It will tell you if

the polarity of the hot and neutral wires is

reversed and if the safety ground is discon-

nected.

• Try another AC outlet if you’re still not sure

if the outlet is properly wired.

• Make sure the plug’s ground pin is not by-

passed with a “3-pin to 2-pin” adapter. This

is important not only for product safety, but

to insure that HUI has an “earth” ground

reference for proper operation of the touch-

circuits.

If the touch circuits still fail to operate properly:

1. Try touching the HUI’s chassis with one

hand to connect your body to the HUI’s ground

reference, and touch the fader knob with the

other hand.

2. Try installing an anti-static mat from an

electronic supply shop, and connect the ground

wire between the mat and the ground lug on

the HUI (located just above the Power switch

on the rear panel.)

3. Try installing a conductive metal sheet

beneath the carpet at your workstation. Con-

nect a wire between the metal sheet and the

ground lug on the HUI.

If none of the above suggestions fix the

problem, try the self-test on page 25. If that

doesn’t work, and you’re sure it’s not a digital/

MIDI-related problem (see next section), refer

to “Service” on the next page.

Digital/MIDI

HUI is a MIDI device. It must be able to

send and receive MIDI data to work with your

DAW. HUI uses a type of active sensing to let

you know that MIDI communication is estab-

lished. This is indicated by a blinking LED in

the bottom right corner of the Time Code Dis-

play. Once MIDI communication is established,

any interruption in the incoming MIDI data

causes “OFFLINE” to be displayed in the VFD,

and the LED to stop blinking.

TROUBLESHOOTING

H U I R E F E R E N C E G U I D E

MIDI configuration software such as OMS

(Open Music System) and FMS (FreeMIDI Sys-

tem) are commonly used to facilitate use of

third party controllers such as HUI. Therefore,

it’s important to make sure that HUI is defined

as a controller device in your OMS or FMS soft-

ware, and also as a controller in the DAW

environment.

First, answer the following OMS/FMS-re-

lated questions before pressing the

PANIC

button (not included on HUI):

• Is AppleTalk off? The computer uses

AppleTalk to operate through its printer

port; AppleTalk can block MIDI transmis-

sion.

• Does OMS/FMS “see” the MIDI interface?

• Is the interface speed set the same in both

the OMS/FMS setup and the hardware inter-

face? MIDI won’t transfer information if the

interface is set to one speed and the soft-

ware is set to another.

• If you have multiple setups, is the setup

document being used the most current one

(or recommended)?

• Are the MIDI instruments connected to the

appropriate port?

• Are all MIDI connections made properly?

(See page 20 for connection diagram.)

• Are your MIDI cables OK?

Many MIDI interface boxes provide indica-

tors to let you know when MIDI data is being

sent and received. If HUI passes the MIDI test

in it’s self-test routine (see page 7), any MIDI

communication problem must lie elsewhere.

Touch one of HUI’s faders and move it a little.

Does the MIDI interface “receive” indicator

light? If it doesn’t, check or replace the MIDI

cable between HUI’s MIDI OUT jack and the

MIDI interface’s IN jack.

Now move one of the faders in the DAW

software. Does the MIDI interface “transmit”

indicator light? If not, check or replace the

MIDI cable between the computer and the

MIDI interface “To Computer” connector.

• Is the device information configured properly?

• Is the correct MIDI channel defined to the

proper MIDI port? (HUI operates on MIDI

channel 1.)

• Is your MIDI interface working properly?

Is it connected to the correct port on your

computer?

• Ummm, is the MIDI interface turned on?

SERVICE

Service for HUIs bought and residing in the

United States is available only Mackie Designs.

(Do not contact Digidesign.) HUI owners out-

side the U.S. should consult their local Mackie

dealer or distributor for service.

Now then, please follow these instructions:

1. Review the Troubleshooting section of

this reference guide (pages 25-26). Assuming

you’ve done so, and used up your voluminous

reserves of common sense…

2. Have your HUI serial number ready —

hopefully you copied it down in the front of this

manual (page 3).

3. Call Mackie Tech Support at 800-258-6883

(8 AM to 5 PM, Pacific Time) to explain the

problem. If it can’t be solved over the phone

you will be issued an RA (Return Authoriza-

tion) number. You must have an RA number

before you can obtain service from the factory.

4. Set aside the power cord, reference guide,

and anything else you want to keep. This may

or may not include half-eaten sandwiches and

large sums of money. Mackie will only send

back your HUI.

5. Pack the HUI in the original box, with the

original foam innards or other packing materi-

als. You DID save that stuff, didn’t you? If you

didn’t, you’ll need to purchase a new box and

packing materials from Mackie. Mackie is not

responsible for any damage resulting from ship-

ments of product in “non-original” packaging.

6. Include a legible note stating your name,

return shipping address (no P.O. boxes of

course), daytime phone number, the RA num-

ber, and a detailed description of the problem,

including how we can duplicate it.

7. Write the RA number in huge letters

on top of the box.

8. Ship the HUI to Mackie. We recommend

UPS (United Parcel Service), and suggest you

get insurance on the package. Send HUI to this

address:Mackie Designs Inc.

Service Department

16220 Wood-Red Rd. NE

Woodinville, WA 98072

9. When we’re finished taking care of HUI,

we’ll try to send it back to you within three

business days. Ask Tech Support for current

turnaround times when you call for your RA

number. We normally send packages via UPS

Blue (second-day air). But, if you rush your

HUI to us via air mail, we’ll do the same for the

return trip. This does not necessarily apply to

non-warranty service.

GLOSSARY

The following is an admittedly short glos-

sary of audio terms used in this owner’s

manual. The more basic terms can be found in

a variety of places; we’d be foolish to forget to

mention our web site. Go to www.mackie.com

to find a more thorough audio glossary. Addi-

tionally, we recommend the following books:

The Audio Dictionary, by Glenn White; Tech

Terms, by Peterson & Oppenheimer; Handbook

for Sound Engineers, by Glen Ballou; and Sound

Reinforcement Handbook, by Gary Davis.

active sensing

MIDI message echoing that occurs between

HUI and the host DAW to confirm that commu-

nication is occuring. The right-hand decimal

point in the Time Code Display blinks once per

second to indicate that MIDI communication is

established.

DAW

See digital audio workstation.

DSP

Abbreviation for digital signal processing.

DSP can accomplish the same functions found

in analog signal processors, but performs them

mathematically in the digital domain, with more

precision and accuracy than its analog counter-

part. Since DSP is a software-based process,

parameters and processing functions are easily

changed and updated by revising the software,

rather than redesigning the hardware. DSP can

be found in an outboard effects device, such as

a reverb or delay unit, or it can be integrated

into a DAW or digital mixing console.

discrete channel

Used in reference to surround-sound appli-

cations, a discrete channel is separate or

isolated from the stereo pair of channels it is

normally associated with.

digital audio workstation (DAW)

A dedicated recording/editing software (appli-

cation) and hardware system, used for hard

disk (non-linear) random access playback and

recording. Many DAWs are used with personal

computers using Windows® 95 or Macintosh®

operating systems, though some use their own

proprietary computers.

effects devices

External signal processors used to add re-

verb, delay, spatial, or psychoacoustic effects

to an audio signal. An effects processor may be

used as an insert processor (serial) on a par-

ticular input or subgroup, or it may be used via

the aux send/return system (parallel). See also

echo, reverb.

FMS

Short for FreeMIDI System. FMS allows your

computer to decipher information coming from

the MIDI interface, which is connected to both

your computer and HUI.

gain stage

An amplification point in a signal path,

either within a system or a single device. Over-

all system gain is distributed between the

various gain stages.

linear, non-linear

Linear audio recording and playback is

sound that has been recorded to tape and

played back in the same linear fashion. Non-lin-

ear recording and playback uses audio sound

files that have been “recorded” to the hard

disk of a computer. Though the sound file in-

formation may be stored in a random fashion

on the hard disk, it is played back in the same

linear way it was recorded.

line level

A signal whose level falls between –10dBu

and +30dBu.

MIDI

Acronym for musical instrument digital inter-

face. MIDI is the music industry’s standard

serial communication protocol. HUI uses MIDI

to bidirectionally communicate with the DAW

software. (Refer to the DAW controller docu-

mentation for specific MIDI routing and

channel information prior to hookup.)

OMS

Short for Open Music System. OMS allows

your computer to decipher information com-

ing from the MIDI interface, which is

connected to both your computer and HUI.

phantom power

A system of providing electrical power for

condenser microphones (and some electronic

pickup devices) from the sound mixer. The sys-

tem is called phantom because the power is

carried on standard microphone audio wiring in

a way that is “invisible” to ordinary dynamic

microphones. Mackie mixers use standard +48

volt DC power, switchable on or off. Most qual-

ity condenser microphones are designed to use

+48 VDC phantom power. Check the

manufacturer’s recommendations.

Generally, phantom power is safe to use

with non-condenser microphones as well, es-

pecially dynamic microphones. However,

unbalanced microphones, and some electronic

equipment (such as some wireless microphone

receivers), can short out the phantom power and

be severely damaged. Check the manufacturer’s

recommendations and be careful!

GLOSSARY

H U I R E F E R E N C E G U I D E

RS-232, RS-422 serial port connection

Two industry standard serial communication

protocols, requiring different 9-pin wiring

schemes. HUI’s RS-232/RS-422 serial port can

be used with either type of connection, deter-

mined by switching to the appropriate protocol.

RS-232 uses unbalanced drivers and receivers,

in which one wire is used per signal. RS-422

uses balanced, or differential, drivers and re-

ceivers, which require two wires per signal.

RS-232 works well for short runs (up to 50

feet), while RS-422 is recommended for longer

runs (up to 1000 feet).

surround-sound

Multi-channel audio playback systems in 4, 5,

or 6 channel formats. Surround-sound is typi-

cally found in movie theaters and home

theater systems. HUI’s control room section

can accommodate up to six discrete (separate)

audio channels, for use in what is termed “5.1

surround.” (4.1 surround can also be monitored

with HUI.)

touch-updatable motor fader

HUI’s fader knobs are made of conductive

metalized plastic, which respond immediately

to touch control via capacitive contact between

the neutral (ground) control surface and the

user. The fader motor uses a high resolution,

tightly-tuned servo amplifier, which moves the

fader knob and stem along a conductive plastic

fader track.

Operationally, when you touch the knob, the

motor disengages from the fader via internal

and software control, concurrently sending out

positional status from HUI to the DAW mixer

map over MIDI or other serial communication.

When you release the fader knob(s), the motor

re-engages via control information from the

DAW mixer map.

VFD

Abbreviation for vacuum fluorescent display.

HUI’s VFD is an 80-character (40 characters by

2 lines) display that shows channel strip DSP

functions and other HUI operation parameters.

V-Pot™

Abbreviation for virtual potentiometer, the V-

Pot is considered a “soft knob” because it

performs various functions determined by the

DAW software being used with HUI. It acts as

a continuous or variable controller and also re-

flects current value or position via its

surrounding 12-segment LED collar.
