SUPERB SOUND is derived from the extremely low distortion, high "Headroom" design.
State-of-the art, low noise, balanced XLR preamps from our Concert Series mixers provide
common mode rejection of better than 78 dB, which means that any possible noise that may
come over your cables is virtually eliminated. Distortion is nearly non-existent with THD below
0.1% from input to output, guaranteeing the purity of your sound. Hear the difference - your
sound will not seem "sterile" or "processed". It will be dynamically open and transparent just
like it was meant to be!
LIGHT WEIGHT and EASY TO USE Controls are logically laid out making the XP
Series simple to use, reducing errors during setup and perfomance. Its compact size and
weight of only 20 lbs. makes it the lightest, most powerful mixer of its kind. No other manufacturer offers a higher performance to weight ratio!

2 INDEPENDENT 24-Bit STEREO DSP EFFECTS allow you to assign each channel to your choice of effects. You can dedicate chorus/reverb to the acoustic guitar channel
and a lush reverb to the vocals, etc. Both effects are adjustable to your stage monitors so you
can hear yourself with full effects. The effects processors with 256 effects each, include
reverbs, choruses, flanging and echoes with fully adjustable parameters for damping, decay,
depth, speed, regeneration and time.
ACTIVE 3 BAND CHANNEL EQ provides easy adjustment for the tone you want. The
80Hz LO frequency controls deliver solid non-flabby bass. A simple adjustment with the MID
band control brings out the best sound for vocals or guitar by affecting the very important
750Hz frequency range. The 11.5k Hz HI treble control adds sparkle to your top-end without
adding harshness. Both the LO and HI controls are "shelving", which means they are effective
from 20Hz to 20kHz.
THREE 7 BAND EQUALIZERS provide precise adjustments to fine tune your overall
sound and to help control feedback. A stereo (dual) graphic equalizer controls the main L and
R outputs and a mono equalizer controls the monitor output.
ENGINEERED TO LAST Every XP Series mixer incorporates a rugged injection molded case and steel chassis. Continuous full power is assured from a high-grade 6063-T5-aluminum heat sink cooled by a variable speed fan. Sealed controls and switches guard against
the outside elements while heavy-duty connectors provide a positive connection to your
cables. Hidden deep in the heart of these mixers is the “SMT” Surface Mount Technology
construction that utilizes surface mounted components to prevent parts from shaking or
vibrating loose. Precision 1% tolerances guarantee that your settings will be accurate every
time. Fire retardant FR-4 military spec circuit cards feature double-sided copper construction
to guard against noise and radio frequencies (RF). The XP Series is made in the USA for years
of dependable service!

QUICK START UP
7. CHANNEL EFFECTS 1&2 LEVEL
13. MAIN LEVEL (L & R AMPS)
If you’re like most new owners, you’re probably in a hurry
to plug your mixer in and use it. Here are some brief instructions to get you going quickly. With the mixer unplugged and
the unit turned off, complete the following procedures:
The EFF 1&2 adjusts the level sent to the dual effects processor and to the front EFF SND 2 jack. The effects control is
post-channel level, which automatically tracks the channel’s
LEVEL & EQ controls. Turning this control to the left will
send to the internal effects processor 1. Turning to the right
will send to the internal effects processor 2 (and the external
EFF 2 SND jack). Center “0” is off. Reduce these levels if the
PK LEDs are flashing on the effects processors.
The MAIN control is the master volume control for all channels. The MAIN signal is sent through the MAIN L-R
GRAPHIC EQ to the L and R amps and the front L / R output
jacks.
A. CONNECTING AC POWER TO YOUR MIXER
• Be sure to plug your mixer into the proper voltage marked
on your mixer, either 120V-60Hz or 240V-50Hz.
• Use only a grounded (3 prong) power outlet to prevent a
shock hazard (do not bypass). This gives the quietest grounding for your mixer.
B. CONNECTING INPUTS TO YOUR MIXER
• For balanced microphones, use a shielded cable and plug
into the XLR MIC inputs.
• For high output devices like instruments & keyboards, plug
into the LINE input jacks using a shielded cable. Adjust the
channel GAIN control for mic or for instrument.
C. TURNING YOUR MIXER ON
• Set all channel and master LEVEL controls to their OFF
positions
• Set all HI, MID, and BASS controls and the GRAPHIC
EQUALIZERS to the center “flat - no boost or cut” position.
• Adjust all channel “PAN” controls to their center position.
• Connect your speakers and monitors at the rear panel.
• Turn the mixer on by the rear POWER SWITCH and watch
for the front POWER LED to come on. Your mixer is now
ready to operate by turning the levels up.
MIC CHANNEL FEATURES
1. XLR MICROPHONE INPUT
The XLR MIC input is designed for balanced low impedance
microphones. The high performance, low noise preamps do
a superb job of noise reduction. The XLR connector is wired
as per the industry standard, pin 1 is ground, pin 2 is noninverting (positive), and pin 3 is inverting (negative). Note:
Make sure the phantom power is switched off before connecting or disconnecting microphones to the mixer.
8. CHANNEL MONITOR CONTROL
The MON control adjusts the volume of the channel going to
the master MONITOR control. The MON control is a preLEVEL control. This means it is unaffected by the channel
LEVEL.
14. MONITOR LEVEL (MONITOR AMP)
The MONITOR master level is sent through the MONITOR
GRAPHIC EQ to the MONITOR amp and front output jack.
15. TAPE OUT LEVEL
The TAPE OUT LEVEL sends the MAIN signal mix to the
TAPE OUT jacks for recording. The TAPE OUT level is unaffected by the MAIN level control so a recording level can be set
independently of the MAIN speaker volume.

2. LINE INPUT JACKS
The LINE input is a 1/4” phone jack designed for balanced or
unbalanced line or instruments. Examples of these inputs
would be guitar, keyboard or effect returns. The line input
can be used at the same time the mic input is being used.
Channels 7/8 and 9/10 feature stereo LINE INPUTS for
stereo (use the top jack for mono input).

3. GAIN CONTROL (CHANNELS 1-6)
The GAIN control adjusts the input sensitivity on both the
LINE and MIC input jacks over a range of 40dB. For quietest
operation, set the GAIN control just below the point where
the PK LED flashes. If the PK LED lights or if distortion is
heard reduce the GAIN slightly until the PK LED is off.
1
4. CHANNEL “PK” LED
The PK LED indicates when the channel is nearing it’s clipping level, causing distortion. Reduce the GAIN slightly to
prevent distortion. On channels 7/8 and 9/10, reduce the
level from your external souce. To get more volume,
increase the master MAIN control and re-adjust your main
mix.
5. CHANNEL LEVEL CONTROL
The LEVEL control adjusts the volume of the channel before
going to the PAN control. Here is where the individual
channel volumes are adjusted to make up the desired mix at
the main outputs.
6. CHANNEL BALANCE CONTROL
The BAL control places the channel between L and R in the
main stereo outputs. At the “0” center setting, the channel will
be heard equally from the L and R outputs.
When both 1/4” jacks are used on channels 7/8 or 9/10, the
BAL adjusts the L-R levels, sending signals from LINE 7/9 to
the LEFT, and signals from LINE 8/10 to the RIGHT.
9-11. CHANNEL TONE CONTROLS
16. TAPE OUT JACKS
Each channel features active 3-band EQ tone controls LO,
MID, and HI. All three function as boost (clockwise) & cut
(counter-clockwise) controls. The center 0 is the “flat” or no
effect position. The LO and HI controls are shelving type
with corner frequencies at 80Hz and 11.5k Hz respectively.
The MID control is a band pass type centered at 750Hz.
These settings will vary with the type of voice or instrument.
Try reducing the MID to add clarity and turn up the LO and
HI for a fuller sound. Channels 7/8 and 9/10 feature stereo
EQ controls.
Use the TAPE OUT L-R jacks for recording or to send to
external power amps. If the TAPE OUT is being used to
record, make sure the TAPE IN jacks are not connected to
the recorder output or turn the channel 9/10 LEVEL to “0” or
feedback will result.
12. TAPE IN JACKS (CHANNEL 9/10)
The L-R TAPE IN inputs on CHANNEL 9/10 are for connecting a
CD or tape player. These TAPE IN jacks can be used for returning another stereo effects processor or instrument (keyboard).
Channel 9/10 inputs are NOT muted by the MUSIC BREAK
switch.
17. EFF 2 SEND JACK
The EFF 2 SEND jack can send a signal to an external processor. This is the same signal sent to the internal EFF 2 processor.
Effect returns can be connected to any input channel. Make
sure the EFF control for the return channel is set to “OFF” or
“EFF1” or feedback will occur.
18. MAIN L-R OUTPUTS
The MAIN L / R outputs are the same signals that feed the
internal LEFT and RIGHT amps. Use these balanced 1/4”
outputs to feed additional power amps, etc..
19. MONITOR OUTPUT
21. EFFECTS PEAK LED’s
The MONITOR output is the same signal that feeds the internal MONITOR amp. Use this balanced output to feed
additional power amps, etc..
The PK LED indicates that the signal level to the processor is
too high. To prevent distortion, turn the EFF 1 & 2 control
towards the center (off) position until the PK LED stops flashing.
20. DUAL EFFECT PROCESSORS
To help prevent feedback, microphones should be placed
behind the main speakers.
To reduce feedback in the low frequency range, try lowering one of the 80Hz or 160Hz sliders. High frequency feedback is usually reduced by lowering the 2kHz or 6kHz sliders.
22. MAIN EFFECTS CONTROL
Two 24-Bit processors provide a host of great sounding
effects including Flange, Reverb, Echo, & Chorus.
The channel EFF 1 & 2 send control delivers the signals to
the processors. Note: Reduce these levels if the red PEAK
LEDs are flashing at the processors.
Turn up the MAIN EFFECTS control to add your effects to the
L-R outputs. Adjust the SELECT and the PARAMETER to get
the desired effect. Note: An audible noise will be heard while
adjusting the effects.
The MAIN EFFECTS level controls the amount of the effects
that go to your L and R outputs.
23. MONITOR EFFECTS LEVEL
The MONITOR EFFECTS level controls the amount of the
effects that go to your MONITORS.
26. OUTPUT LED’s /AMP “CLIP” LED’s
The OUTPUT METER LEDs indicate the output levels for
each power amp. The yellow “+6” LED indicates the output
level is near maximum. The red CLIP LEDs indicate when
the power amps are starting to distort (clip). Reduce the
MAIN and/or MONITOR master levels to prevent distortion.
27. POWER LED
The blue POWER LED indicates the mixer is powered ON.

The mixer will “protect”, engaging relays to mute the speakers if: a) impedance is below minimum on any amplifier b)
shorted speaker cables, or c) ventalation problems. If the
LED comes on, shut the mixer OFF and check for cable
problems, proper impedance and obstructed rear cooling
vents. If you encounter an over-heat problem, leave the
mixer ON allowing the fan to cool down the internal components. The mixer will auto-reset in about 5 minutes.
29. 48V PHANTOM POWER SW/LED
The 48V PHANTOM POWER switch turns on the microphone phantom power in the channel XLR jacks. This
power is used for supplying a high voltage to condenser
microphones. The LED indicates the phantom power is
turned on. The phantom power will not damage conventional dynamic microphones. Note: Make sure the phantom
power is switched off before connecting or disconnecting
microphones to avoid a “pop”.

24. MUSIC BREAK SWITCH/LED
The MUSIC BREAK feature turns off all inputs, except for channel 9/10. This is useful during breaks. This allows pre-recorded music to be played through the TAPE IN jacks. The channel 9/10 MIC/LINE inputs are left active for announcements or
solo acts. The remaining input channels (1-8) are turned OFF
eliminating feedback or other unwanted sounds from open
mics during breaks or changes. The LED indicates the MUSIC
BREAK is ON. The internal effects are also muted.
25. GRAPHIC EQ L/R + MONITOR
When the EQ sliders are in their center position, they do not
affect the audio signal. When EQ sliders are raised or lowered from this position, they boost or cut a narrow frequency band.
For tone enhancement you may want to raise the 80Hz and
160Hz sliders (for deeper bass) and the 6kHz and 12kHz sliders (for crisper highs) while reducing the 400Hz, 800Hz and
2kHz sliders in a moderate “curve”.
The rear panel contains the POWER SWITCH and AC power
cable connection. There are 3 groups of speaker jacks. Each
group has one Speakon™ connector and two 1/4” outputs
(wired in parallel).
The L / R amps have a 4Ω MIN IMPEDANCE
(Maximum one 4Ω or two 8Ω speakers per amp).
The MONITOR amp has a 2Ω MIN IMPEDANCE
(Maximum two 4Ω or four 8Ω speakers per amp).

A NOTE ABOUT SPEAKER IMPEDANCE (Ω) and CABLES
As you add more speakers to an amp, the total impedance (ohms) is
reduced. The L / R amplifiers will drive an impedance of 4Ω or higher. This
means up to two 8Ω speakers, or one 4Ω speaker, for each amp.
The MONITOR amplifier will drive an impedance of 2Ω or higher. This means
it will drive up to four 8Ω speakers, or up to two 4Ω speakers.
Speaker cables should be a minimum 16 gauge for up to 50ft (PH50).
Heavy-duty Speakon™ 12 gauge cables (SP100) are recommended for lengths
over 50ft.
