20. NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
CAUTION: Changes or modifications to this device not expressly
approved by LOUD Technologies Inc. could void the user's authority to
operate the equipment under FCC rules.
21. This apparatus does not exceed the Class A/Class B (whichever is
applicable) limits for radio noise emissions from digital apparatus as
set out in the radio interference regulations of the Canadian Department
of Communications.
ATTENTION — Le présent appareil numérique n’émet pas de bruits
radioélectriques dépassant las limites applicables aux appareils
numériques de class A/de class B (selon le cas) prescrites dans le
réglement sur le brouillage radioélectrique édicté par les ministere des
communications du Canada.
22. Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here:

1202-VLZ3

We realize that you must be wanting to
try out your new 1202-VLZ3. All we ask is
that you read this page NOW, and the rest
can wait until you’re good and ready. But
do read it — you’ll be glad you did.
WARNING: Before you plug the AC power
cord into the mixer, make sure the VOLTAGE
SELECTOR switch is set to the same voltage
as your local AC mains supply (see page 12).

Level-Setting Procedure
Message to seasoned pros: do not set levels using the
old “Turn the GAIN up until the clip light comes on,
then back off a hair” trick. When a Mackie mixer clip
light comes on, you really are about to clip. We worked
and slaved to come up with a better system, one that
provides low noise and high headroom.

Adjusting input levels (Chs. 1–4 only)
On the first four channels, it’s not even necessary to
hear what you’re doing to set optimal levels. But if you’d
like to: Plug headphones into the PHONES jack, then
set the CONTROL ROOM/SUBMIX knob about one-quarter of the way up.
The following steps must be performed one channel at
a time:

Other Nuggets of Wisdom
For optimum sonic performance, the channel LEVEL
knobs and the MAIN MIX knob should be set near the
“U” (unity gain) markings.
Always turn the MAIN MIX and CONTROL ROOM/
SUBMIX level controls down before making connections
to and from your 1202-VLZ3.
If you shut down your equipment, turn off your amplifier or powered speakers first. When powering up, turn
them on last.
Save the shipping box! You may need it someday.

Instant Mixing
Here’s how to get going right away, assuming you have
a microphone and a keyboard:
1. Plug your microphone into channel 1’s MIC
input.
2. Turn on the 1202-VLZ3.
3. Perform the Level-Setting Procedure.
4. Connect cords from the MAIN OUTS (XLR, 1⁄4"
or RCA, your choice) to your amplifier.
5. Hook up speakers to the amp and turn it on.
6. Turn up the 1202-VLZ3’s channel 1 LEVEL knob
to the center detent and the MAIN MIX knob
one quarter of the way up.

1. Turn the GAIN, LEVEL and AUX send knobs
fully down (counterclockwise).

7. Sing like a canary!

2. Set the EQ knobs at the center detent.

9. Turn that channel’s LEVEL knob to the center
detent.

3. Connect the signal source to the input.
4. Engage (push in) the SOLO switch.
5. Play something into the selected input. This
could be an instrument, a singing or speaking
voice, or a line input such as a CD player or
tape recorder output. Be sure that the volume
of the input is the same as it would be during
normal use. If it isn’t, you might have to readjust these levels during the middle of the set.
6. Adjust the channel’s GAIN control so that the
display on the right LED meter stays around “0”
and never goes higher than “+7.”

Owner’s Manual

1202-VLZ3

Introduction
Thank you for choosing a Mackie professional compact mixer. The 1202-VLZ3 is equipped with our precision-engineered XDRTM Extended Dynamic Range
premium studio-grade mic preamp.

This icon marks information that is critically
important or unique to the 1202-VLZ3. For your
own good, read them and remember them. They
will be on the final test.

Now that you have your 1202-VLZ3, find out how to get
the most from it. That’s where this manual comes in.

This icon will lead you to in-depth explanations of features and practical tips. While not
mandatory, they usually have some valuable
nuggets of information.

How To Use This Manual
Since many of you folks will want to hook up your
1202-VLZ3 immediately, the first pages you will encounter after the table of contents are the ever-popular
hookup diagrams. These show typical mixer setups for
Record/Mixdown, and Stereo PA.
After this section is a detailed tour of the entire mixer.
Every feature of the 1202-VLZ3 is described “geographically;” in other words, in order of where it is physically
placed on the mixer’s top or rear panel. These descriptions are divided into the first three sections, just as
your mixer is organized into three distinct zones:

Appendix A is a section on troubleshooting and repair
information.
Appendix B is a section on connectors: XLR connectors, TRS balanced connectors, TS unbalanced connectors, and Insert connectors.
Appendix C shows the technical specifications, and
a block diagram showing the internal signal path and
general goings-on within the mixer.

Patchbay: The patchbay along the top and back,
where you connect things.
Channel Strip: The eight channel strips where you
adjust each channel.
Output Section: The output section on the right.
Throughout these sections you’ll find illustrations,
with each feature numbered. If you’re curious about a
feature, simply locate it on the appropriate illustration,
notice the number attached to it, and find that number
in the nearby paragraphs.

PHANTOM POWER
Most modern professional condenser mics are
equipped for phantom power, which lets the mixer
send low-current DC voltage to the mic’s electronics
through the same wires that carry audio. (Semi-pro
condenser mics often have batteries to accomplish the
same thing.) “Phantom” owes its name to an ability to
be “unseen” by dynamic mics (Shure SM57/SM58, for
instance), which don’t need external power and aren’t
affected by it anyway.

Each LOW CUT switch, often referred to as a High
Pass Filter (all depends on how you look at it), cuts bass
frequencies below 75 Hz at a rate of 18 dB per octave.
We recommend that you use low-cut on every microphone application except kick drum, bass guitar, or
bassy synth patches. These aside, there isn’t much down
there that you want to hear, and filtering it out makes
the low stuff you do want much more crisp and tasty.
Not only that, but low-cut can help reduce the possibility of feedback in live situations, and it helps to conserve
amplifier power.
Another way to consider low-cut’s function is that it
actually adds flexibility during live performances. With
the addition of low-cut, you can safely use low equalization on vocals. Many times, bass shelving EQ can really
benefit voices. Trouble is, adding low EQ also boosts
stage rumble, mic handling clunks and breath pops.
Applying low-cut removes all those problems, so you can
add low EQ without losing a woofer.
Here’s what the combination of low EQ and low-cut
looks like in terms of frequency curves:

CONSTANT LOUDNESS ! ! !

TROL ROOM [15] and PHONES [12] outputs. If you
want the ALT 3–4 signals to go back into the main mix,
engage the ASSIGN TO MAIN MIX [36] switch, and the
CONTROL ROOM/SUBMIX [34] level control becomes
the one knob to control the levels of all the channels
assigned to ALT 3–4.

The 1202-VLZ3’s PAN controls employ a design called
“Constant Loudness.” It has nothing to do with living
next to an all-night disco. As you turn the PAN [26]
knob from left to right (thereby causing the sound to
move from the left to the center to the right), the sound
will appear to remain at theALLsame volume
(or loudness).

1202-VLZ3

This control gives you up
to 15 dB boost or cut above
12 kHz, and it is also flat
at the detent. Use it to add
sizzle to cymbals, and an
overall sense of transparency, or edge to keyboards,
vocals, guitar and bacon
frying. Turn it down a little
to reduce sibilance, or to
hide tape hiss.

Each AUX send level ranges from off through unity
(the center detent position) on up to 15 dB of extra gain
(when turned fully clockwise). Chances are you’ll never
need this extra gain, but it’s nice to know it’s there if
you do.

MODERATION DURING EQ
With EQ, you can also screw things up royally. We’ve
designed a lot of boost and cut into each equalizer circuit, because we know everyone will occasionally need
that. But if you max the EQs on every channel, you’ll
get mix mush. Equalize subtly and use the left sides of
the knobs (cut), as well as the right (boost). Very few
gold-record-album engineers ever use more than about
3 dB of EQ. If you need more than that, there’s usually a
better way to get it, such as placing a mic differently (or
using a different kind of mic entirely).

Channel 5–12 AUX knobs control the mono sum of
the channel’s stereo signals for each AUX send. For
instance, channel 5 (L) and 6 (R) mix together to feed
that channel’s AUX send knobs.
We recommend going into a stereo reverb in mono and
returning in stereo. We have found that on most “stereo”
reverbs the second input just ties up an extra AUX send
and adds nothing to the sound. There are exceptions, so
feel free to try it both ways. If your effects device is true
stereo all the way through, use AUX 1 to feed its left
input and AUX 2 to feed the right input.

29. HI EQ

Still with us? Good for you. Here come the tricky
parts, the output or master section where the mixing is
really done. We have even started it on a new page:

30. AUX 2 SEND
31. AUX 1 SEND
These knobs allow you to tap a portion of each channel signal out to another source for parallel effects
processing or stage monitoring. AUX send levels are controlled by these knobs and by the AUX 1 MASTER [39].
These are more than just effects and monitor sends.
They can be used to generate separate mixes for recording or “mix-minuses” for broadcast. By using AUX 1 in
the PRE mode, these mix levels can be obtained independently of the channel’s LEVEL control.
AUX 1 in post mode and AUX 2 are post-LOW CUT,
post-EQ and post-LEVEL. That is, the sends obey the
settings of these controls. AUX 1 in PRE mode follows
the EQ and LOW CUT settings only. PAN and LEVEL
have no effect on the PRE send (see diagram below).

Typically, the engineer sends the main mix to an

what if the engineer in the control room needs to hear
something other than the main mix? With the 1202VLZ3, the engineer has several choices of what to listen
to. This is one of those tricky parts, so brace yourself.

32. MAIN MIX
This knob controls the levels of signals sent to the
main outputs: XLR [13] and 1⁄4" [11] and RCA TAPE
OUTPUT [10]. All channels and STEREO RETURNS [7]
that are not muted or turned fully down will wind up in
the main mix.
Fully counterclockwise is off, the center detent is
unity gain, and fully clockwise provides 12 dB of additional gain. This additional gain will typically never be
needed, but once again, it’s nice to know it’s there. This
is the knob to turn down at the end of the song when
you want The Great Fade-Out.

Via these SOURCE switches, you can choose to listen
to any combination of main mix, ALT 3-4 and Tape. By
now, you probably know what the main mix is. ALT 3-4 is
that additional stereo mix bus. Tape is the stereo signal
coming in from the TAPE INPUT [9] jacks.
Selections made in the source matrix deliver stereo
signals to the control room, phones and meter display.
With no switches engaged, there will be no signal at
these outputs and no meter indication.
The exception is the solo function. Regardless of
the source selection, engaging a channel’s SOLO [24]
switch will replace that selection with the solo signal,
also sent to the control room, phones and right meter
(the left meter becomes inactive). This is what makes
the Level-Setting Procedure so easy to do.
WARNING: Engaging both the TAPE and
ASSIGN TO MAIN MIX [36] buttons can
create a feedback path between TAPE INPUT
[9] and TAPE OUTPUT [10]. Make sure your tape deck
is not in record, record-pause, or input-monitor mode
when you engage these switches, or make sure the CONTROL ROOM / SUBMIX 34] level knob is fully counterclockwise (off).
Now you know how to select the signals to send to the
engineer’s control room or phones. From there, these
signals all pass through the same level control:

34. CONTROL ROOM/SUBMIX
This knob controls the levels of both the stereo CONTROL ROOM [15] and PHONES [12] outputs. The control range is from off through unity gain at the detent,
with 10 dB of extra gain (when turned fully clockwise).
When MAIN MIX is your control room source selection, those signals will now pass through two level controls on the way to your control room amp and phones
— the MAIN MIX [32] knob and this CONTROL ROOM
/ SUBMIX knob. This way, you can send a nice healthy
level to the main output (MAIN MIX knob at “U”), and
a quiet level to the control room or phones (CONTROL
ROOM / SUBMIX knob wherever you like it).
When ALT 3-4 or TAPE is selected, or SOLO [24] is
engaged, the CONTROL ROOM / SUBMIX knob will be
the only one controlling these levels (channel controls
not withstanding).

1202-VLZ3

A WORD ABOUT PRE-FADER SOLO (PFL)
Engaging a channel’s SOLO [24] switch will cause
this dramatic turn of events: Any existing control room
source selections will be replaced by the solo signal,
appearing in the control room, headphones, and in the
right meter. The audible solo levels are then controlled
by the CONTROL ROOM / SUBMIX [34] knob. The solo
levels appearing on the right meter display are not controlled by anything — you wouldn’t want that. You want
to see the actual channel level on the meter display
regardless of how loud you’re listening.
“PRE-FADER” SOLO means that the channel signal
is being tapped before the channel’s LEVEL [23] knob
(not really a fader in this case, but we were afraid you’d
laugh if we called it Pre-Knob Solo). It does, however,
obey GAIN [4], LOW CUT [3] and EQ [27] settings,
making it the perfect tool for quick inspections of suspect channels. The channel’s PAN [26] and MUTE/ALT
3-4 [25]settings have no effect on the solo signal.
Note: For stereo channels 5-12, the solo signal is the
mono sum of the left (odd-numbered) and right (evennumbered) signals for that channel strip.
WARNING: PRE-FADER SOLO [24] taps the
channel signal before the LEVEL knob. If you
have a channel’s LEVEL knob set below “U”
(unity gain), SOLO won’t know that, and will send a
unity gain signal to the control room, phones and meter
display, that may result in a startling level boost at these
outputs.

35. RUDE SOLO LIGHT
This flashing Light Emitting Diode serves two purposes — to remind you that at least one channel is in solo,
and to let you know that you’re mixing on a Mackie. No
other company is so concerned about your level of solo
awareness. If you work on a mixer that has a solo function with no indicator lights, and you happen to forget
you’re in solo, you can easily be tricked into thinking
that something is wrong with your mixer. Hence the
RUDE SOLO LIGHT. It’s especially handy at about 3 a.m.
when no sound is coming out of your monitors but your
multitrack is playing back like mad.

36. ASSIGN TO MAIN MIX
Let’s say you’re doing a live show. Intermission is nearing and you’ll want to play a soothing CD for the crowd
to prevent them from eating the furniture. Then you
think, “But I have the CD player plugged into the TAPE
inputs, and that never gets to the MAIN OUTS!” Oh, but
it does. Simply engage this switch and your control room
source selection, after going through the CONTROL
ROOM / SUBMIX [34] knob, will feed into the main mix,
just as if it were another stereo channel.
Another handy use for this switch is to enable the ALT
3-4 mix to become a submix of the main mix, using the
CONTROL ROOM/SUBMIX knob as its level control.

Owner’s Manual

Whatever your selection, you can also use the CONTROL ROOM [15] outputs for other applications. Its
sound quality is just as impeccable as the MAIN OUTS
[11 and 13]. It can be used as additional main mix
output, which may sound silly since there are already
three, but this one has its own level control. However,
should you do something like this, be sure that you do
not engage a SOLO switch, as that will interrupt your
SOURCE selection.

Side effects: (1) Engaging this switch will also feed
any soloed channels into the main mix, which may be
the last thing you want. (2) If you have MAIN MIX as
your control room source selection and then engage ASSIGN TO MAIN MIX, the main mix lines to the control
room will be interrupted to prevent feedback. Then
again, why would anyone want to assign the main mix to
the main mix?

37. METERS – MANY DISPLAYS IN ONE!
The 1202-VLZ3’s peak metering system is made up of
two columns of twelve LEDs. Deceptively simple, considering the multitude of signals that can be monitored by
it.
If nothing is selected in the SOURCE matrix and no
channels are in SOLO, the METERS will just sit there
and do nothing. To put them to work, you must make
a selection in the SOURCE matrix (or engage a SOLO
switch).
Why? You want the meter display to reflect what the
engineer is listening to, and as we’ve covered, the engineer is listening either to the CONTROL ROOM [15]
outputs or the PHONES [12] outputs. The only difference is that while the listening levels are controlled by
the CONTROL ROOM / SUBMIX [34] knob, the meters
read the SOURCE mix before that control, giving you the
real facts at all times, even if you’re not listening at all.
Thanks to the 1202-VLZ3’s wide dynamic range,
you can get a good mix with peaks flashing anywhere
between –20 and +10 dB on the METERS. Most amplifiers clip at about +10 dB, and some recorders aren’t so
forgiving either. For best real-world results, try to keep
your peaks between “0” and “+7”.
You may already be an expert at the world of “+4” (+4
dBu=1.23 V) and “–10” (–10 dBV=0.32 V) operating
levels. Basically, what makes a mixer one or the other
is the relative 0 dB VU (or 0 VU) chosen for the meters.
A “+4” mixer, with a +4 dBu signal pouring out the back
will actually read 0 VU on its meters. A “–10” mixer,
with a –10 dBV signal trickling out, will read 0VU on its
meters. So when is 0 VU actually 0 dBu? Right now!

ARWord About Aux

First of all, there is no particular alliance between
AUX
SEND 1 (or 2) and STEREO RETURN 1 (or 2).
MAIN OUT
They’re just numbers. They’re like two complete strangMONO
ers.

At the risk of creating another standard, Mackie’s
compact mixers address the need of both crowds by
calling things as they are — 0 dBu (0.775 V) at the
output shows as 0 dB VU on the METERS. What could
be easier? By the way, the most wonderful thing about
standards is that there are so many to choose from.

SENDS are outputs, RETURNS are inputs. The channel AUX [30 and 31] knobs tap the signal off the channel
and sends it to the AUX SEND [8] outputs. AUX 1
R
signal is sent to the AUX 1 MASTER [39] knob before
going to the AUX SEND 1 [8] output and the AUX 2

Besides being used to work effects into your mix, Aux
Sends serve another critical role — that of delivering
cue mixes to stage monitors, so musicians can hear what
they’re doing. On the 1202-VLZ3, AUX SEND 1 can play
either role, depending on the position of this switch.
With this switch up (disengaged), AUX SEND 1 will
tap a channel pre-fader (LEVEL) and pre-MUTE/ALT
3-4, meaning that no matter how you manipulate those
controls as they feed the main mix, the AUX SEND will
continue to belt out that channel’s signal. This is the
preferred method for setting up stage monitor feeds. EQ
settings will affect all AUX SENDs.

So, the original “dry” signals go from the channels to
the main mix and the affected “wet” signals go from the
STEREO RETURN [7] to the main mix, and once mixed
together, the dry and wet signals combine to create a
glorious sound. So, armed with this knowledge, let’s visit
the Auxiliary World:

With the switch down, the AUX SEND 1 becomes an
ordinary effects send — post-fader (LEVEL) and postMUTE/ALT 3-4. This is a must for effects sends, since
you want the levels of your “wet” signals to follow the
level of the “dry.”

POWER

CONTROL
ROOM
SOURCE

These outputs can be fed to the inputs of a reverb or
other device. From there, the outputs of this external
device are fed back to the mixer’s STEREO RETURN [7]
jacks. Then these signals are sent through the STEREO
RETURN [40] level controls, and finally delivered to the
main mix.

LEVEL
SET

This knob provides overall level control of AUX SEND
1, just before it’s delivered to the AUX SEND 1 [8] output. (AUX SEND 2 has no such control.) This knob goes
from off (turned fully down), to unity gain at the center
detent, with 10 dB of extra gain (turned fully up). As
with some other level controls, you may never need the
additional gain, but if you ever do, you’ll be glad you
bought a Mackie.
This is usually the knob you turn up when the lead
singer glares at you, points at his stage monitor, and
sticks his thumb up in the air. (It would follow suit that
if the singer stuck his thumb down, you’d turn the knob
down… but that never happens.)

40. STEREO RETURNS
These two controls set the overall level of effects received from STEREO RETURN [7] inputs 1 and 2. These
controls are designed to handle a wide range of signal
levels, from off, to unity gain at the detent, with 20 dB
gain fully clockwise, to compensate for low-level effects.

Engage the RETURN TO AUX 1 switch, and now the
STEREO RETURN 2 knob will become an additional
AUX SEND 1 knob for the signal at AUX RETURN 1. Say
that ten times! Once again, AUX RETURN 1 will behave
normally, as always.
Congratulations! You’ve just read about all the features of your 1202-VLZ3. You’re probably ready for a cold
one. Go ahead. The rest of the manual can wait.

Signals passing through these controls will proceed
directly to main mix, with one exception (see paragraph
below). The STEREO RETURNs do not have MUTE/ALT
3-4 switches, so if you want these signals to get to the
ALT 3-4 mix, you’ll have to patch the effects device’s
outputs into one of the stereo channels, and MUTE/ALT
those channels.

Owner’s Manual

Typically, these knobs can just live at the center
detent, and the effects device’s output control should
be set at whatever they call unity gain (check their
manual). If that turns out to be too loud or too quiet,
adjust the effects device’s outputs, not the mixer. That
way, the mixer’s knobs are easy to relocate at the center
detent.

41. RETURN TO AUX 1
If you want to add reverb or delay to the stage monitor
mixes of AUX 1, this is the switch for you.
With the switch up, STEREO RETURN 1 and 2 behave
normally — they deliver their signals into the main mix.
With the switch down, STEREO RETURN 1 still behaves
normally, but STEREO RETURN 2 will feed AUX SEND 1
instead of the main mix.
Still with us? Good. So far, with the switch down, we
have STEREO RETURN 1 feeding the main mix and
STEREO RETURN 2 feeding AUX SEND 1. Now, suppose you only have one effects device, and you want it to
feed both the MAIN MIX and AUX SEND 1. That’s where
“jack normalling” comes in:

Appendix A: Service Information
If you think your Mackie product has a problem,
please check out the following troubleshooting tips and
do your best to confirm the problem. Visit the Support
section of our website (www.mackie.com/support)
where you will find lots of useful information such as
FAQs, and documentation. You may find the answer to
the problem without having to send your Mackie product away.

Troubleshooting
Bad Channel
•

Is the MUTE/ALT 3–4 switch in the correct
position?

•

Is the LEVEL knob turned up?

•

Try unplugging any INSERT devices (Channels
1–4 only).

•

Try the same source signal in another channel,
set up exactly like the suspect channel.

Bad Output
•

Is the associated level knob (if any) turned up?

•

If it’s one of the MAIN OUTS, try unplugging
all the others. For example, if it’s the 1⁄4"
Left Main out, unplug the RCA and XLR Left
outputs. If the problem goes away, its not the
mixer.

•

If it’s a stereo pair, try switching them around.
For example, if a left output is presumed dead,
switch the left and right cords, at the mixer
end. If the problem switches sides, it’s not the
mixer.

Noise
•

Turn the channel LEVEL and AUX RETURN
knobs down, one by one. If the sound disappears, it’s either that channel or whatever is
plugged into it, so unplug whatever that is. If
the noise disappears, it’s from your whatever.

Power
•

Unplug the power cord and check the fuse.

“XLR” Connectors

Mackie mixers use 3-pin female “XLR” connectors on
all microphone inputs, with pin 1 wired to the grounded
(earthed) shield, pin 2 wired to the “high” (”hot” or
positive polarity) side of the audio signal and pin 3
wired to the “low” (“cold” or negative polarity) side of
the signal. See Figure A. This is all totally aboveboard
and in full accord with the hallowed standards dictated
by the AES (Audio Engineering Society).
Use a male “XLR”-type connector, usually found on the
nether end of what is called a “mic cable,” to connect to
a female XLR jack.

You can cook up your own adapter for a stereo
microphone adapter. “Y” two cables out of a
female 1⁄4" TRS jack to two male XLR plugs,
one for the Right signal and one for the Left.
•

Balanced mono circuits. When wired as a balanced connector, a 1⁄4" TRS jack or plug is connected tip to signal high (hot), ring to signal
low (cold), and sleeve to ground (earth).

Unbalanced Send/Return circuits. When wired
as a send/return “Y” connector, a 1⁄4" TRS jack
or plug is connected tip to signal send (output
from mixer), ring to signal return (input back

Switched 1⁄4" Phone Jacks
Switches can be incorporated into 1⁄4" phone jacks,
which are activated by inserting the plug. These switches may open an insert loop in a circuit, change the input
routing of the signal or serve other functions. Mackie
uses switches in the channel insert and bus insert
jacks, input jacks and stereo returns. We also use these
switches to ground the line-level inputs when nothing is
plugged into them.
In most cases, the plug must be inserted fully to
activate the switch. Mackie takes advantage of this in
some circuits, specifying circumstances where you are
to insert the plug only partially. See Special Mackie
Connections, on the next page.

RCA Plugs and Jacks

Special Mackie Connections

RCA-type plugs (also known as phono plugs) and
jacks are often used in home stereo and video equipment and in many other applications (Figure D). They
are unbalanced and electrically identical to a 1⁄4" TS
phone plug or jack. See Figure C. Connect the signal to
the center post and the ground (earth) or shield to the
surrounding “basket.”

The balanced-to-unbalanced connection has been
anticipated in the wiring of Mackie jacks. A 1⁄4" TS plug
inserted into a 1⁄4" TRS balanced input, for example,
will automatically unbalance the input and make all the
right connections. Conversely, a 1⁄4" TRS plug inserted
into a 1⁄4" unbalanced input will automatically tie the
ring (low or cold) to ground (earth).

SLEEVE TIP SLEEVE TIP

Figure D: RCA Plug

Unbalancing a Line
In most studio, stage and sound reinforcement situations, there is a combination of balanced and unbalanced inputs and outputs on the various pieces of
equipment. This usually will not be a problem in making
connections.
•

•

When connecting a balanced output to an
unbalanced input, be sure the signal high (hot)
connections are wired to each other, and that
the balanced signal low (cold) goes to the
ground (earth) connection at the unbalanced
input. In most cases, the balanced ground
(earth) will also be connected to the ground
(earth) at the unbalanced input. If there are
ground-loop problems, this connection may be
left disconnected at the balanced end.
When connecting an unbalanced output to a
balanced input, be sure that the signal high
(hot) connections are wired to each other. The
unbalanced ground (earth) connection should
be wired to the low (cold) and the ground
(earth) connections of the balanced input. If
there are ground-loop problems, try connecting
the unbalanced ground (earth) connection only
to the input low (cold) connection, and leaving
the input ground (earth) connection disconnected.
In some cases, you will have to make up special
adapters to interconnect your equipment. For
example, you may need a balanced XLR female
connected to an unbalanced 1⁄4" TS phone
plug.

1202-VLZ3

TRS Send/Receive Insert Jacks
Mackie’s single-jack inserts are the three-conductor,
TRS-type 1⁄4" phone. They are unbalanced, but have
both the mixer output (send) and the mixer input
(return) signals in one connector. See Figure E.

Figure E

The sleeve is the common ground (earth) for both
signals. The send from the mixer to the external unit is
carried on the tip, and the return from the unit to the
mixer is on the ring.

Using the Send Only on an Insert Jack
If you insert a TS (mono) 1⁄4" plug only partially (to
the first click) into a Mackie insert jack, the plug will
not activate the jack switch and will not open the insert
loop in the circuit (thereby allowing the channel signal
to continue on its merry way through the mixer).
This allows you to tap out the channel or bus signal
without interrupting normal operation.
If you push the 1⁄4" TS plug in to the second click, you
will open the jack switch and create a direct out, which
does interrupt the signal in that channel. See Figure F
on the next page.
NOTE: Do not overload or short-circuit the signal you
are tapping from the mixer. That will affect the internal
signal.

Channel Insert jack

Direct out with no signal interruption to master.
Insert only to first “click.”

A mono signal connected to the RIGHT jack will show
up in the right bus only. You probably will only want to
use this sophisticated effect for special occasions.

MONO PLUG
Channel Insert jack

Direct out with signal interruption to master.
Insert all the way in to the second “click.”

Mults and “Y”s
A mult or “Y” connector allows you to route one output
to two or more inputs by simply providing parallel wiring connections. You can make “Y”s and mults for the
outputs of both unbalanced and balanced circuits.

Owner’s Manual

MONO PLUG

A stereo signal, having two plugs, should be patched
into the LEFT (MONO) and the RIGHT input or return
jacks. A jack switch in the RIGHT jack will disable the
mono function, and the signals will show up in stereo.

Remember: Only mult or “Y” one output into
several inputs. If you need to combine several
outputs into one input, you must use a mixer,
not a mult or a “Y.”

Mackie Stereo Inputs and Returns: Mono,
Stereo, Whatever
Stereo line inputs and stereo returns are a fine
example of the Mackie philosophy (which we just made
up) of Maximum Flexibility with Minimum Headache.
The inputs and returns will automatically be mono or
stereo, depending upon how you use the jacks. Here’s
how it works:
A mono signal should be patched into the input or
return jack labeled LEFT (MONO). The signal will be
routed to both the left and right sides of the return circuit, and will show up in the center of the stereo pair of
buses it’s assigned to, or it can be panned with the PAN
[26] control.
