Power-up Procedure
You are now ready to power up the system. Be sure to do so in the sequence outlined below.
10. If any effects processors, electronic instruments, tape recorders or CD players are connected
to the mixer, switch them on.
11. Connect the mixer’s Power Supply Unit (PSU) to the mixer and to AC power. Note that the
POWER light on the mixer illuminates. Also note the locking tab - you will need to press it to
release the connector when disconnecting the PSU.
12. Switch on the power to the EON15 G2s. The green LED on the front baffle will illuminate.
13. Reverse this process when shutting down your system.
Set Levels
14. On the EON15 G2s bring the INPUT 1 LEVEL control to the 10:00 o’clock position.
15. On input channel 1 of the mixer engage the ON switch.
16. On input channel 1 of the mixer engage the LISTEN switch. This will allow you to observe the
signal level on the mixer’s meters. Note the LISTEN ON LED illuminates.
17. Speak or sing into the microphone connected to channel 1 (or ask the performer to do so).
Make sure that the performer holds the microphone and speaks or sings as they will during
the actual performance.
18. Slowly rotate the channel 1 SENS control CW (clockwise) until you see the following
indications on the meter…
•When the performer is at their “normal” performance level, the meter should indicate “0”.
•When the performer is at their loudest you should see the meter reaching to “10”.
•An occasional flickering of the top LED on the meter during the loudest passages is OK. If
this light illuminates steadily, reduce the SENS control setting by turning it CCW.
7

19. Bring the channel 1 FADER up to the “0” position.
20. With the performer speaking / singing, slowly bring the MIX L and MIX R faders up until the
desired level is reached. Listen carefully for the onset of feedback and be prepared to bring
the MIX L and MIX R faders down.
21. Set the PAN control to position the sound in the stereo field. With this control centered the
sound will be heard equally in both speakers.
22. Disengage the channel 1 LISTEN switch.
23. Repeat steps 15 thru 22 for all other channels that are in use.
Congratulations – you’ve successfully set-up your system. Now let’s fine tune the mix.
Setting Channel EQ
The term “EQ” is shorthand for Equalization. The tone control on your radio or stereo is a most
basic form of EQ. Sound reinforcement equipment offers more comprehensive control over tonal
balance. Here is a table describing undesired tonal characteristics and how to handle them.
Sound Quality EQ Adjustment
• Too dark, lacks brilliance, seems muddy • Turn up the HF (High Frequency)
• Speech is not clear, vocals don’t project • Increase the MF (Mid Frequency) level
• Rotate the MF frequency control to locate the
desired frequency
• Not enough bass, sound is thin, lacks power • Turn up the LF (Low Frequency)
and authority • Disengage the LOW CUT control
• Sound is brittle, “S” sounds are too hissy, • Turn down the HF
very high-frequency feedback is heard
• Sound is honky or nasal sounding • Turn down the MF EQ
• Rotate the MF frequency control until the sound
quality improves
• Sound is boomy or rumbling, feedback is • Turn down the LF
heard at very low frequencies • Engage the LOW CUT control
• With a lavaliere mic, speech has too much • Turn down the MF LEVEL and set the MF
low mid content frequency control between 300 and 500
Fine Tuning the Mix
Adjust the channel FADERS until the desired blend is achieved.
With the performers speaking or singing, observe the PEAK indicator on the EON15 G2 input panel.
This indicator flashes when the loudspeaker’s on-board amplifiers are approaching maximum out-
put. Occasional flashes are normal for very loud operation. However, if the PEAK LED stays illumi-
nated, the sound may be distorted and it is an indication that more speakers or a lower perform-
ance volume may be required for your specific application.
Doing More With Your System
The Quick Start section of this guide addresses a simple 2-speaker system with microphones only.
This section will explain more advanced uses for your EON System.
Other Sources
In addition to microphones, your EON system will accommodate many sources. Some of these
sources may require special adapters or adapter cables. See the “Connectors” section for more
information.
8

Playback Sources
Any device that plays pre-recorded audio fits into this category.
• Cassette or DAT players
• CD
• Mini-Disc
• mp3 Playback Devices
• Computer audio outputs
• Video Cassette Recorders (VCRs), DVD players, Laser Disc players
• Turntables (note that turntables require a special pre-amplifier and will not work properly when
connected directly to a mixer input.)
Musical Instruments
Technology has brought us an array of musical instruments that rely on digital electronics to pro-
duce their sound. In addition, many traditional acoustic instruments may have special pick-ups
installed so they can be amplified without the use of microphones. Musical instrument sources
include:
• Digital pianos and synthesizers.
• Digital drums and drum machines.
• Electrified acoustic guitars (acoustic guitars that have had a special pick-up installed that allows
them to be amplified and retain their acoustic sound character)
Regarding electric guitars (as opposed to electrified acoustic guitars) – the tonal and distortion
characteristics of the guitar amp and speaker are part of the sound of the instrument. Plugging an
electric guitar directly into a sound system will usually not yield satisfactory results. 9
The following illustration shows how various sources may be connected to your EON MusicMix 16
mixer.

Effects and Signal Processors
Your MusicMix 16 mixer is designed to accommodate a variety of audio processors. The following
illustration shows examples of how these devices would be connected to your mixer.
Connecting and Using Digital Effects Processors
Digital signal processing (DSP) technology has produced effects processors that are low cost and
packed with features and performance. These processors can enhance your performance by
adding studio quality reverb and effects to your sound. Your effects processors can easily be
connected to your mixer as shown. Here’s how to set-up and use your effects processor with
your MusicMix 16.
1. Complete the system set-up as described in the Quick Start section of this guide.
2. Connect your effects processor as shown in the illustration.
3. Determine which inputs will have the effect applied. For this discussion, let’s add reverb to a
vocal mic on input channel 1.
4. Bring the channel 1 EFX control to the 2:00 o’clock position.
5. Bring the EFX MASTER control to the 2:00 o’clock position.
6. Engage the LISTEN switch next to the EFX MASTER control. Note the LISTEN ON LED lights.
7. Ask the performer to speak or sing into the microphone. Observe the MusicMix16 METER and
make sure that it is not being driven past the top LED. Disengage the EFX LISTEN switch.
10

8. Bring the INPUT LEVEL control of your effects processor up…
•If the processor has an input meter or a clip (or peak) LED, bring the input level control up
until the clip LED lights on the loudest peaks then back off slightly.
•If the processor has no input meter or LED bring the input level control to the 2:00 or 3:00
o’clock position (see the effects processor user guide).
9. Engage the channel 11-12 LISTEN switch.
10. Slowly rotate the channel 11-12 SENS control CW (clockwise) until you see the following
indications on the meter…
•When the performer is at their “normal” performance level, the meter should indicate “0”.
•When the performer is at their loudest you should see the meter reaching “10”.
•An occasional flickering of the top LED on the meter during the loudest passages is OK. If
this light illuminates steadily, reduce the SENS control setting by turning it CCW.
11. Engage the channel 11-12 ON switch.
12. Bring the channel 11-12 FADER up until the desired level of effects is heard through the speakers.
13. Disengage the LISTEN switch.
Adding a Second Effects Processor
A second effects processor may be added to the system (see “Effects Processor 2” in the illustration
for connection details). If a second effects processor is used, be sure to set the EFX2 / MON2 switch
to the EFX2 (disengaged) position. Note that the use of a second effects processor will prevent the
use of a second monitor mix (see “Adding Monitors to Your System”).
Signal Processors
A signal processor is typically used to modify (rather than add to) an audio signal. This being the case,
signal processors are typically connected to the “insert” point of the mixer (see the “Controls and
Connections” section of this Guide).
Adding Monitors to Your System
In live sound reinforcement a monitor speaker is a speaker that is intended to be heard by someone
other than the audience. There are two types of monitors that your EON MusicMix 16 mixer will sup-
port.
11

Stage Monitors
Stage monitors (sometimes called “foldback” speakers) are used to allow the performers to hear
themselves and each other. Frequently the performers will need to hear a different blend (a “mix”)
of the microphones and direct inputs than the audience is hearing. The “MON” and “MON2” sec-
tions of your MusicMix 16 allow two independent mixes to be sent to performer’s stage monitors.
An additional set of EON powered speakers is a great choice for stage monitors. The illustration
shows how to use EON powered speakers in a monitor application. Here’s how to operate the sys-
tem.
1. Complete the system set-up as described in the Quick Start section of this guide.
2. Connect at least one EON powered speaker to the MON output of the mixer as illustrated.
3. Set the controls on the EON monitor speaker as directed in the Quick Start section of this guide.
4. Turn on the power to the EON monitor speaker.
5. Bring the EON monitor speaker’s level control to the 10:00 o’clock position.
6. On the mixer bring the MON master control to the 2:00 o’clock position.
7. Determine which channels you want to hear in the monitors and, one at a time slowly bring the
MON control of those channels up until the desired level is heard.
Control Room or Booth Monitors
Ideally, the person operating the mixer should be in the audience area hearing exactly what the
audience hears. But sometimes the system operator has to mix from a control room or booth. The
MusicMix 16 has a CONTROL ROOM OUT feature that supports the use of booth monitors. The
signal that is sent to the control room monitors is identical to that which is supplied to the PHONES
output.
• With the MIX / TAPE CD switch in the MIX position and with all LISTEN switches disengaged the
Control Room monitors will receive the same signal as the main speakers.
• With the MIX / TAPE CD switch in the TAPE CD position and with all LISTEN switches disengaged
the Control Room speakers will monitor TAPE / CD IN.
• When a LISTEN switch is engaged, the signal from the associate channel or output will replace
the MIX or TAPE CD signal.
• The CONTROL ROOM & PHONES control adjusts the level of both the Control Room monitors
and the headphones.
Subwoofers
Much contemporary music relies on low-frequency energy for its impact and power. Subwoofers
are speakers that are especially designed to produce the frequencies below approximately 125 Hz.
The EON PowerSub G2 shown in the following example is a powered subwoofer that can be easily
added to your EON G2 system if you need even more low-frequency output.
12

Basic Stereo System with Subwoofers
In this illustration the MIX L & R outputs of the MusicMix16 are connected to the inputs of the left
and right subwoofers. The loop-thru feature of the subs is used to feed the left and right EON15 G2
speakers. To operate the system…
• Connect the system as shown in the illustration.
• Set the input level control of the EON PowerSubs fully CCW (counter clock wise).
• Adjust the system as described on the Quick Start section of this guide.
• Slowly bring up the level controls of the EON PowerSubs until the desired balance is achieved.
For further tips, see the EON PowerSub User’s Guide.
Recording a Live Performance
There are a number of ways in which the MusicMix 16 may be used to make a live recording of a
performance. When making such a recording it is important to remember that the recording may
not sound like the actual performance. This is because the recording will only include the sound
that is picked up by the microphones (or direct inputs to the mixer). Instruments that are heard
acoustically in the venue may not be captured to tape. For example, a vocalist singing into a micro-
phone will be recorded onto tape just fine. But the bass guitar amp (which sounds great in the
venue) is not going directly to the mixer so the only way it gets onto tape is by bleeding into the
vocal microphone. The result will be lots of vocals and not much bass guitar. Details on live
recording are beyond the scope of this User’s Guide, but the following information will help you
understand how to take advantage of the features of your MusicMix 16 mixer.
13

Stereo Method 1
If the performance does not require the use of stage monitors you can use the MON and EFX2 /
MON2 outputs to create an independent stereo mix for recording. Connect your recorder to the
MON and EFX2 / MON2 outputs as shown and set the EFX2 / MON2 switch to the MON 2 position.
Connect your headphones to the recorder. Bring up the MON control of a mixer input channel to
record it to the left channel. Bring up the EFX2 / MON2 control of a mixer channel to record it to
the right channel. To center a mixer channel, set the MON and EFX2 / MON2 controls to the same
position. Note that MON and EFX2 / MON2 are not effected by the channel faders, so changes in
the live sound mix will not effect the recording.
Stereo Method 2
Connect your recorder to the CONTROL ROOM OUT jacks of your MusicMix 16 mixer. Disengage
all LISTEN switches. Disconnect the headphones from the mixer. Set the MIX / TAPE CD switch to
the MIX position (disengaged). The CONTROL ROOM & PHONES control will adjust the level of the
signal going to the recorder. Note that you will not be able to use the LISTEN system while recording.
You may monitor the recording by connecting headphones to the headphone jack of the recorder.
Direct to Multi-Track
Digital multi-track recorders are affordable and widely available. With the help of a simple ‘Insert /
Direct Out Adapter’ (see the illustration) it’s possible to make a multi-track recording of a perform-
ance. Over-dubs can be added in the studio and a final mix can be perfected.

Block Diagram
Mono Input Channel
MIC INPUT CONNECTOR
The MIC input accepts XLR-type connectors and is designed to accommodate a wide range of
BALANCED or UNBALANCED signals. If you engage the 48V PHANTOM POWER switch (top right-
hand side of the mixer) the input provides a suitable powering voltage for professional condenser
mics (this is also known as Phantom Power).
LINE INPUT CONNECTOR
Accepts 3-conductor Tip-Ring-Sleeve (TRS) 1/4” or 2-conductor 1/4” phone jacks. Use this input
for sources other than mics, such as keyboards, drum machines, synthesizers, tape machines or
guitars. When using unbalanced sources, it is best to keep cable lengths as short as possible. The
MIC input and the LINE input on a single channel can not be used simultaneously.
INS CONNECTOR
The INSERT point is a break in the channel allowing limiters, compressors, special EQ or other
signal processing units to be added in the signal path. The INS is a 3 conductor 1/4” phone plug.
When a jack is inserted, the signal path is broken just before the EQ section and the signal is rout-
ed out of the mixer via the tip of the connector. The signal can then be processed and returned to
the mixer via the ring of the TRS jack. The Send may be tapped off as an alternative pre-fade, pre-
EQ direct output if required, using a lead with tip and ring shorted together so that the signal path
is not interrupted.
SENS
The input SENSITIVITY matches the source level to the mixer. If this control is set too high the
signal will distort as it overloads the channel. Too low, and the level of any background hiss will be
more noticeable and you may not be able to get enough signal level to the output of the mixer.
Note that the lowest number (-60 dBu) would deliver the greatest “gain” and would be used, for 15

example, for microphones positioned some distance from the source. The 0 dBu setting would be
used when a device such as another mixer is connected to the input. The Quick Start section of
this guide will provide details on properly setting this control.
LOW CUT
Pressing this switch activates a steep 100 Hz., 18dB per octave high-pass filter which reduces the
level of bass frequencies. Use this in live PA situations to clean up the mix, reduce stage rumble,
microphone handling noise, or reduce `popping’ from microphones. Unless the source is specifically
intended to produce bass content, it is usually better to engage the Low Cut filter.
HF
HF stands for HIGH FREQUENCY EQUALIZER. Turn clockwise to boost high (treble) frequencies
(12kHz and above) by up to 15dB, adding “crispness” or “sparkle” to cymbals, vocals and elec-
tronic instruments. Turn counter clockwise to cut by up to 15dB, reducing hiss or excessive sibi-
lance which can occur with certain types of microphone. Set the knob in the center-detent position
when not required.
MID
These two knobs work together to form a SWEPT MID EQ. The lower knob provides 15dB of
boost and cut, just like the HF EQ knob, but the frequency at which this occurs can be set by the
upper knob over a range of 240Hz to 6kHz. This allows some truly creative improvement of the
signal in live situations, because this mid band covers the range of most vocals. Listen carefully as
you use these controls together to find how particular characteristics of a signal can be enhanced
or reduced. Set the gain (lower) knob to the center-detent position when not required. Note that
when the gain knob is centered the frequency knob will have no effect. ‘Q’ or ‘width’ of the filter is
set at 1.5.
LF
Turn clockwise to boost low (bass) frequencies (60Hz and below) by up to 15dB, adding warmth to
vocals or extra punch to synths, guitars and drums. Turn counter clockwise to cut low frequencies
by up to 15dB for reducing hum, stage rumble or to improve a mushy sound. Set the knob to the
center-detent position when not required.
MON
The MON (Monitor) send is always PRE-FADE, POST-EQ (meaning that this signal will be effected
by the EQ but not by the master fader) and therefore most appropriate for stage monitor (also
known as “foldback”) mixes.
EFX2 / MON2
This auxiliary send may be used either as a second send to an effects device such as a digital
reverb or as a second monitor send.
• When the master EFX2 / MON2 switch is set to the EFX2 position (disengaged) the signal will be
taken after the EQ and master fader which is ideal for feeding an effects device.
• When the master EFX2 / MON2 switch is set to MON2 position (depressed) the signal will be
taken before the EQ and master fader which is ideal for feeding a stage monitor system.
EFX
The EFX (effects) send is what you will use to feed an external effects device. It is always POST-
FADE, POST-EQ.
PAN
This control sets the amount of the channel signal feeding the Left and Right main output allowing
you to move the source smoothly across the stereo image. When the control is turned fully right or
left you are able to route the signal to either left or right outputs individually.
ON
All outputs from the channel, except inserts, are muted when the ON switch is released and
enabled when the switch is down, allowing levels to be pre-set before the signal is required.
16

FADER
The 100mm FADER is custom designed to give smoother control of the overall signal level in the
channel strip and allowing precise balancing of the various source signals being mixed to the
Master Section. You get most control when the input SENSITIVITY is set up correctly, giving full
travel on the fader. See the Setting Up, Gain Structuring & Troubleshooting’ section for help in
setting a suitable signal level.
LISTEN
When the latching LISTEN switch is pressed, the audio signal from the channel is fed to the head-
phones, control room output and meters, where it replaces the selected monitor source (MIX or
TAPE/CD IN). The LISTEN signal is derived after the EQ but before the channel fader so it is not
effected by fader level. The LISTEN LED on the Master section illuminates to warn that LISTEN is
active. Engaging the LISTEN switch does not effect the signal to the MIX, MON, or EFX outputs.
LISTEN allows you to hear one input at a time so you can adjust EQ or check a channel for prob-
lems without interfering with the performance.
Stereo Input Channels
The MusicMix 16 actually has 4 stereo input channels.
• Inputs 9-10 and 13-14 are very basic inputs that can only send a signal to the MIX output.
• Inputs 11-12 and 15-16 are more fully featured. This is where you would connect a stereo
keyboard, or an effects processor, or a CD player with pre-recorded accompaniment tracks.
9L / 10R and 13L / 14R INPUTS
These high impedance inputs are unbalanced and use RCA “phono” connectors. This is a good
place to connect a CD player for background music during breaks. If you’ve run out of input chan-
nels you could also connect the output of an effects processor here but you will not be able to
send the effect to the stage monitors. Alternatively they may be used as simple effects returns or
stereo instrument inputs. Note that turntables require special (RIAA) pre-amplifiers and will not work
properly if connected directly to these inputs.
9-10 and 13-14 LEVEL
These controls adjust the level of the sources connected to inputs 9L / 10R and 13L / 14R.
11L / 12R and 15L / 16R INPUTS
These inputs accept 1/4” phone jacks and are BALANCED for low noise and top quality from pro-
fessional equipment. You may also use UNBALANCED sources simply connecting 2-conductor
1/4” phone jacks. These inputs are ideal for sources such as keyboards, drum machines, synths,
tape machines or effects processors. Mono sources may be used by plugging into the left jack
only.
SENS 11-12 and 15-16
The input SENSITIVITY matches the source level to the mixer. If this control is set too high the sig-
nal will distort as it overloads the channel. Too low, and the level of any background hiss will be
more noticeable and you may not be able to get enough signal level to the output of the mixer.
HF
Same as mono input channels.
LF
Same as mono input channels.
MON
The MON (Monitor) send is always PRE-FADE, POST-EQ (meaning that this signal will be effected
by the EQ but not by the master fader) and therefore most appropriate for stage monitor (also
known as “foldback”) mixes. If a stereo source is connected to the channel, the left and the right
signals will be summed and sent to the stage monitors.
17

EFX2 / MON2
This auxiliary send may be used either as a second send to an effects device such as a digital
reverb or as a second monitor send.
• When the master EFX2 / MON2 switch is set to the EFX2 position (disengaged) the signal will be
taken after the EQ and master fader which is ideal for feeding an effects device.
• When the master EFX2 / MON2 switch is set to MON2 position (depressed) the signal will be
taken before the EQ and master fader which is ideal for feeding a stage monitor system.
• If a stereo source is connected to the channel, the left and the right signals will be summed and
sent to the stage monitors or effects processor.
EFX
The EFX (effects) send is what you will use to feed an external effects device. It is always POST-
FADE, POST-EQ. If a stereo source is connected to the channel, the left and the right signals will be
summed and sent to the effects processor.
BALANCE
This control sets the amount of the channel signal feeding the Left and Right main outputs, allow-
ing you to balance the source in the stereo image. When the control is turned fully right or left you
feed only that side of the signal to the mix.
ON
Same as mono channels.
FADER
Same as mono channels.
LISTEN
The LISTEN function on the stereo channels is identical do that on the mono channels except that
both the left and right inputs are summed to mono in the LISTEN system.

48V Phantom Power
Many professional condenser microphones need an external powering voltage, also known as
PHANTOM POWER. This is a method of sending a powering voltage down the same wires as the
mic signal. Press the switch to supply the 48V Phantom Power to all of the MIC inputs. The adja-
cent LED illuminates when the power is active. Note that mics designed to work with lower phan-
tom voltages will work fine with 48V Phantom Power.
DO NOT CONNECT UNBALANCED SOURCES TO THE XLR INPUTS with 48V Phantom Power
switched on as the phantom power voltage may damage them. Balanced dynamic mics can
normally be used with 48V Phantom Power switched on (contact your microphone manufac-
turer for guidance).
Mics should always be plugged in, and all output faders set to minimum before switching 48V
Phantom Power ON to avoid damage to external equipment.
POWER INDICATOR
This LED illuminates to show when power is connected to the console.
BAR GRAPH METERS
The 3-color peak reading BAR GRAPH METERS normally follow the Monitor selection to show:
• The level of the MIX RIGHT and MIX LEFT outputs or…
• The TAPE/CD IN input if the TAPE/CD TO MIX switch is pressed or…
• When any LISTEN switch is pressed, the meters switch to show the selected LISTEN signal on
both meters, in mono.
In typical operation, keep the average signal level around the 0 level with peaks going into the
amber section (see “Set Up and Gain Structuring”).

L / R SUM
The main MIX L & R signals are combined (summed) and sent to the L/R SUM output jack. Output
level is set by this rotary control.
CONTROL ROOM & PHONES LEVEL
These controls set the output level to the control room LEFT & RIGHT and HEADPHONE outputs.
If HEADPHONES are plugged into the PHONES jack, the Control Room outputs are cut off and the
knob then sets the headphone listening level. When the PHONES are unplugged the Control Room
output is restored. When any LISTEN switch is pressed, the LISTEN signal is sent to the Control
Room Outputs and Headphones without interrupting the other outputs from the mixer. The LISTEN
LED illuminates to show that LISTEN is the source for the monitors and meters. The original
monitor source is restored when the LISTEN switches are released.
MIX TAPE/CD
Pressing the MIX TAPE/CD switch routes the TAPE/CD IN source to headphones, meters and
control room monitors. The MIX output will not be heard in headphones, meters and control room
monitors when this switch is in the TAPE/CD position (depressed).
TAPE/CD LEVEL
The rotary control sets the level of the TAPE/CD input.
TAPE/CD IN TO MIX
Press this switch to add the TAPE/CD IN signal to the stereo Mix, at a level set by the TAPE/CD
LEVEL control. The signal is added pre-insert, pre-fader, and is an ideal way of feeding pre-show
music to the mix in live applications, or could be used as an alternative effects return or line level
input if required.
MON MASTER
The MON (Monitor) master control adjusts the overall level of the MON output used to feed stage
monitors.
EFX2 / MON2 MASTER
This control adjusts the overall level of the EFX2 / MON2 output which may be used to feed stage
monitors or effects processors.
EFX MASTER
The EFX (Effects) master control adjusts the overall level of the EFX output used to feed an effects
processor.
LISTEN (MON, EFX2 / MON2, EFX)
Routes the associated output signal to the CONTROL ROOM or PHONES, replacing any existing
signal. The METERS also switch from the selected source to display the LISTEN signal and the
LISTEN LED lights to warn that a LISTEN switch is pressed. The level of the signal heard on the
headphones or the control room monitors depends on the setting of the associated master level
controls.
EFX2 / MON2
Determines if the EFX2 / MON2 send is configured for use with effects processors (EFX2) or to
drive stage monitors (MON2).
• Select the MON2 position (depressed) to make all the EFX2 / MON2 sends PRE-FADE, POST-EQ.
This means that they will all be unaffected by the position of the channel faders, making them
ideal for foldback or monitoring.
• Select the EFX2 position (disengaged) to make all the EFX2 / MON2 sends POST-FADE, POST-
EQ. This means they will fade up and down with the channel faders. This is more suitable for
effects sends.
MIX L & R – Master Faders
The MIX L & R faders set the final level of the LEFT OUT and RIGHT OUT. 19

Output Section
MON
This 1/4” phone jack output will be used primarily to drive the stage monitor system. The MON
output may be used for balanced or unbalanced operation.
EFX2 / MON2
This 1/4” phone jack output may be used to drive a second stage monitor system or a second
effects processor depending on the setting of the EFX2 / MON2 switch. The EFX2 / MON2 output
may be used with balanced or unbalanced input devices.
EFX
This 1/4” phone jack output may be used to drive an effects processor. The EFX2 / MON2 output
may be used with balanced or unbalanced input devices.
L/R SUM
This 1/4” phone jack output delivers a combination of the MIX L & R signals. The output level is
controlled by the L/R SUM knob. This output may be used to drive a subwoofer or a remote
speaker system covering an overflow area. This output may be used with balanced or unbalanced
devices.
MIX INSERT L & R
These 1/4” phone jacks function in the same way as the channel INS jacks and allow a signal
processor to be inserted into the main stereo mix.
CONTROL ROOM OUT L & R
These 1/4” phone jacks are used to connect a control room (or booth) monitor system. This output
will carry the same signal as the headphone out. The CONTROL ROOM OUT jacks may also be
used to connect a recorder to record a performance. Note that if these jacks are used for recording
you must disconnect the headphones from the PHONES connector. You will also not be able to use
the LISTEN system while recording.
MIX L & MIX R
These balanced XLR connectors are the main stereo outputs of the mixer.
TAPE / CD IN
These RCA jacks are provided for connection of a tape, mini-disc, or CD player. The signal from
these jacks is controlled by the MIX / TAPE CD switch and the TAPE / CD LEVEL control.
PHONES
This stereo phone jack is provided for connection of headphones. Connecting headphones to this
jack will mute the CONTROL ROOM OUT.
PSU
This 3-pin connector is provided for connection of the Power Supply Unit. Note the tab release on
the cable connector for the PSU. This tab must be depressed to disconnect the PSU from the
mixer.
