Using a Microphone

Be sure that the XP308i’s Power switch is set to the off

position.

• Turn all of the channel VOLUME (VOL) controls fully

counterclockwise to the “0” position.

• If the speakers are not connected, connect the

speaker’s wire as described in the previous section.

• Next, connect the power cable to an AC socket.

• Using a standard XLR cable, plug a microphone

into the XP308i’s Channel 1 MIC INPUT.

• Switch the XP308i’s Power switch to the ON

position.

• Set the Channel 1 VOLUME (VOL) control to about

half way.

• While speaking into the microphone, slowly raise

the MASTER level control until you have reached

the desired level.

XP308i Quick Start

In the following pages of this manual, you will find a

detailed eXPanation of all the XP308i’s functions and

controls, but if you just want to get started quickly

you can follow the steps below.

Unpacking and Setting Up the XP308i

• Unpack all the system components fromthe

shipping carton and save all the packing material

in (the unlikely) case your unit ever needs to be

returned for service.

• Remove the mixer by turning the quarter turn

screw counter clockwise towards the RELEASE

position.

IMPORTANT NOTE! – In order to ensure proper

ventilation, always remove the mixer before

powering it on.

• Remove the accessory compartment cover by

turning the quarter turn screw counter clockwise

towards the RELEASE position and remove the

included speaker cables.

• Replace the accessory panel by aligning the

bottom of the panel into the slots, make sure the

quarter turn screw is in the RELEASE position, then

close the panel and turn the quarter turn screw

clockwise to LOCK.

• Position the speakers on the floor or on stands and

using one of the included speaker cables, connect

the mixer’s LEFT SPEAKER OUT to the left speaker’s

input connector. Next use the second included

speaker cable to connect the RIGHT SPEAKER OUT

to the right speaker’s input connector.

Using a Line Level Signal

• Be sure that the XP308i’s Power switch is set to the

OFF position.

• Turn the VOLUME controls fully counterclockwise

to the off position.

• Connect the power cable to an AC socket.

• Using standard ¼-inch cables, connect a line

level signal from akeyboard into the XP308i’s LINE

INPUTS.

• Switch the XP308i’s Power switch to the ON

position.

• Now, play your guitar or keyboard and slowly raise

the channel control and the MASTER level control

until you have reached the desired VOLUME.

Microphone Positioning - How to Reduce

Feedback

Feedback is the annoying howling and squealing

that is heard when the microphone gets too

close to the speaker and the volume is high. You

get feedback when the microphone picks up

the amplified signal from the speaker, and then

amplifies through the speaker again, and then picks

it up again, and so on and so on. In general, it is

always recommended that any LIVE mic (a mic that’s

on) is positioned behind the speaker enclosures. This

will give you the best level from your system before

Electric Acoustic

Guitar

XP308i Quick Start

feedback. One possible exception is when you are

adjusting the sounds of the microphones, since

you want to listen in front of the speaker to hear

properly. To do this, lower your mixers MASTER

VOLUME while setting the EQ and effect from in

front of the speakers. Once you have the sound you

like, move the microphones to behind the speakers

and raise the MASTER volume.

Speaker Placement

Whenever possible, it is a good idea to raise the

speakers above the heads of the listening audience.

The XP308i enclosures’ feature standard 1 3/8” pole

mount receptacles, which are compatible with

speaker stands from a variety of manufacturers

including the models LS2, TS50 and TS100 from

Samson. In a smaller setting like a school cafeteria,

library, or a mall kiosk, you can also use the XP308i

on its side in the tilt back monitor position, which

will improve the projection of the speakers and may

eliminate the need for speaker stands.

1. MIC – XLR connector (channels 1 - 4)

Use these XLR jacks to connect low impedance

microphones to the XP308i’s built-in mic preamps.

2. LINE - ¼-inch phone connector (channels 1 - 4)

Use these 1/4” jacks to connect instrument or audio

source with line-level signals to the XP308i. You can

connect the outputs from acoustic guitar pickups,

keyboards, drum machines, CD/MP3/TAPE players

and other units with line level outputs here.

3. MIC/LINE – switch (channels 1 - 4)

The MIC position changes the gain of both input

jacks to MiC level. The LINE position reduces the

gain of both jacks by 30dB to line level.

4. HIGH FREQUENCY(HF) – control knob

The HF knob controls the amount of treble

applied to that channel. The channel’s HIGH

frequency response is flat when the knob is in

the “12:00” position. Rotating the knob towards

the right will boost the channel’s high frequency

response above 10 kHz by 15dB, and rotating

it towards the left will cut the high frequency by

15dB.

5. LOW FREQUENCY (LF) – control knob

The LF knob controls the amount of bass applied

to that channel. The channel’s LOW frequency

response is flat when the knob is in the “12:00”

position. Rotating the knob towards the right will

boost the channel’s low frequency response below

100 Hertz by 15dB, and rotating it towards the left

will cut the frequency by 15dB.

6. REVERB – switch (channels 1 - 4)

Use the REVERB switch to add a reverb effect to

a mic or line input on any of the inputs 1 – 4. The

REVERB switch is used in conjunction with the mas-

ter REVERB return control knob #23.

7. REVERB LED – indicator (channels 1 - 4)

The REVERB LED will illuminate when the REVERB

switch is pressed down indicating the channel is set

to add reverb. See number 6 above.

8. VOLUME (VOL) – control knob

Sets the overall level for the Mic or Line input.

using RCA connectors on channels 5/6 and 7/8.

Use these RCA inputs for connecting the output

of devices such as MP3, CD, computer soundcard,

cassette player, or any other line level device.

11. MONITOR OUT - 1/4-inch phone jacks

The signal present at the MONITOR OUT jacks is

sent from the MONITOR level control knob, which

is fed from the input channels. In many live sound

situations, a monitor speaker is set up facing

the performer or speaker. The XP308i provides a

dedicated output, with level control (see 21) to send

the stereo mix to a monitor speaker or speakers. To

run a monitor from it XP308i, use the MONITOR OUT

by connecting the to a powered monitor or power

amp and monitor speaker.

12. REC OUT – RCA jacks

This output is used to send the main mix to

an external recorder. The signal present at this

connector is the MAIN bus signal before it has

passed through the MASTER level control. The

nominal output level is -10dBV and the impedance

is 100 Ohms.

13. SPEAKER OUT - 1/4-inch phone jacks

The XP308i has two 1/4-inch phone connectors,

which are powered outputs used to connect your

left and right speaker. Use the included speaker

cables to connect the speakers.

CAUTION: The total impedance load for each side

of the amplifier must not exceed 4 Ohms, therefore

do not connect additional speakers to the XP308i

mixer.

14. AC - IEC inlet

to turn down the MASTER level controls before

plugging and unplugging the mic cables when the

phantom power is active.

19. POWER LED - indicator

The Power LED will illuminate when the MAIN power

switch is turned on.

20. SPEECH /MUSIC – switch

The SPEECH MUSIC switch is use to change the

overall frequency response, or tone contour for the

XP308i sound system. The SPEECH setting boosts

the mid a little for vocal articulation, while the

MUSIC setting boost the lows and highs for a more

hi-fi sound. If your application is mainly for MUSIC,

press the switch down to select the MUSIC response

curve. If your application is mainly for speech, leave

the switch up to select the speech response curve.

21. MONITOR – control knob

The MONITOR volume control is used to control the

overall level sent to the MONITOR OUT, which can be

used to send to a second set of powered speakers

for monitors.

22. MASTER – control knob

The Master volume knob controls the overall output

level. This knob determines the final output signal

level. Signals from all eight channels are routed

here just before being routed to the built-in power

amplifiers and Left and Right output jacks (see #13

above).

23. REVERB - control knob

The REVERB control knob is use to adjust the total

amount of reverb added to any channels with their

REVERB switch (see #6 above) pressed down.

24. METER - LED indicators

This six-segment bar meter shows the XP308i’s

output level. For optimum signal-to-noise ratio,

set the Volume control so that program material is

usually at or around +3 to +6 VU, with occasional

but not steady excursions to the red “LIMIT”

segment.

most any speaker stands without the need for any

additional adapters. The LS2, TS50 and TS100 speaker

stands from Samson are recommended.

• Using one of the included speaker cables

connect the mixer’s LEFT SPEAKER OUT to the

left speaker’s input connector.

• Next use the second included speaker cable to

connect the RIGHT SPEAKER OUT to the right

speaker’s input connector.

Connecting Microphones And Instruments

1. Before connecting your microphones or

instruments, make sure that the power of all

your systems components, including the XP308i,

is turned off. Also, make sure that the VOLUME

controls of each channel of the XP308i and the

MASTER level control are turned all the way

down.

2. Connect the cables to your microphones and

instruments, and insert the other end of the

cable firmly into the appropriate input on the

XP308i.

3. Switch on the power of any peripheral devices,

and then power up the XP308i.

NOTE: Since the XP308i contains two power

amplifiers, it is important to remember the Golden

Rule of audio … “ LAST ON, FIRST OFF”. Translated,

this means that when turning on your system, you

should always turn your power amplifiers on LAST,

and when turning your system off, turn your power

amps off FIRST. This helps avoid any loud pops

caused by in rush current at power up or power

down, which can sometimes damage loudspeakers.

Setting up The XP308i system

1. Remove the accessory compartment cover

by turning the quarter turn screw counter

clockwise towards the RELEASE position and

remove the included speaker cables.

2. Remove the mixer by turning the quarter turn

screw counter clockwise towards the RELEASE

position.

IMPORTANT NOTE! – In order to ensure proper

ventilation, always remove the mixer before

powering it on.

3. Place the mixer on a table-top and extend

the kickstand to provide a comfortable,

ergonomically correct mixing angle. For added

flexibility, you can attach a standard mic

stand adapter to the bottom of the mixer for

mounting on a standard microphone stand.

4. Plug the power cable into an available power

source but keep the mixer’s POWER switch off

for now.

Note: The XP308i’s power supply is a universal voltage,

switching supply, so it will operate on any voltage from

100 to 240 volts.

5. Position the speakers on the floor or on stands.

In order to minimize the possibility of feedback,

be sure to carefully consider where you locate

the speakers. It’s always a good idea to place

the speakers in front of any live microphones. If

possible, use speakers stands to help project the

sound above the audience. Since the XP308i’s

speakers include built-in standard,1 3/8-inch

(35mm) speaker stand receptacles, you can use

4. Set the MASTER level control to about halfway

up.

5. While speaking into the mic (or playing the

instrument), adjust the channel GAIN control

so that the “PEAK” LED of the channel lights

occasionally, then back it down slightly.

6. Slowly adjust the channel VOLUME control until

the desired level is reached.

7. If you wish to adjust the tone of each channel,

adjust the LF and HF equalizer controls as

desired. If you add a lot of EQ, you may have to

re-adjust the channel VOLUME.

8. Use the MASTER level control and SPEECH /

MUSIC switch to adjust the overall volume and

tone.

Using The Reverb Effect

The XP308i features a built-in, high quality, Reverb

effect that you can add to channels 1 through 4.

You can use the REVERB to create a studio effect by

simply following the steps below.

1. Connect a mic or instrument to the desired

channel, and adjust the volume and equalizer to

your liking.

2. Now press the REVERB switch down on the

channel you want to add the reverb effect to.

4. Once you have selected the channels for effects

by using the channel REVERB switch, raise the

REVERB main level control to apply the amount

of reverb effect.

NOTE: If the effect sound is distorted, lower the

REVERB main level.

Using Monitor Speakers.

In many live sounds applications, it’s necessary

to have a monitor system to help the performers

hear their performance. A monitor system includes

a dedicated signal from the main mixer feeding

amps and monitor speakers, or powered monitor

speakers, facing the performers on stage.

Monitor speakers are typically angled enclosures

and can be miniature stand mounted monitors used

in small situations, or for medium to large PA set-ups

floor monitors are used.

The XP308i’s mixer provides a MONITOR OUT on

two ¼-inch phone jacks for connecting additional

speakers.

Follow these steps to connect your monitor

speakers.

Be sure to select the correct type of monitor

speakers. The MONITOR OUT is a line level, un-

powered output so you must use a powered

monitor (like the Samson LIVE 612M) or a passive

monitor with a power amp.

Place the monitor in position.

Connect a standard, shielded instrument type cable

with ¼-inch phone plugs from the MONITOR OUT

Left and Right jacks to the input of each monitor as

shown in the diagram below.

neatly into the top of the XP308i’s mixer allowing

you to interface the latest iPod MP3 players

to provide background music for meetings or

performances. Follow the steps below to install your

MP3 player.

1. Before you connect your iPod, check to see if it

came with a dock adapter. If your iPod player

came with a dock adapter, fit it in the XP308i’s

docking station.

2. Next, simply place the iPod player in the dock.

3. If an optional iPod MP3 player is installed, its

output arrives at 7/8, so use the channel 7/8

VOLUME control to adjust the iPod’s playback

volume.

Configuring the XP308i for Carry Case

You can easily carry your sound system using the

XP308i’s “Slide and Lock” feature. The “Slide and

Lock” speaker enclosures allow you to connect

booth speakers together into a single easy to carry

unit. Follow these simple steps to configure the

XP308i for easy transport.

• Place one speaker on the floor and set it on its

side.

• Grab the second speaker and while holding it

above the first speaker, line up the “slide and

lock” tracks and grooves so they are parallel with

the speaker on the floor.

Configuring the XP308i for Carry Case

• Slide the second speaker into the speaker on the
