INTRODUCTION
Thank you for choosing one of Phonic’s many quality
compact mixers. The MU 1202 and 1202X Compact
Mixers – designed by the ingenious engineers that
have created a variety of mixers fantastic in style and
performance in the past – display similar prociency
that previous Phonic products have shown; with more
than a few renements, of course. The entire MU series
features full gain ranges, amazingly low distortion lev-
els, and incredibly wide dynamic ranges, just showing
the dominance these small machines will have in the
mixing World.
We know how eager you are to get started – wanting
to get the mixer out and hook it all up is probably your
number one priority right now – but before you do, we
strongly urge you to take a look through this manual.
Inside, you will nd important facts and gures on the
set up, use and applications of your brand new mixer. If
you do happen to be one of the many people who atly
refuse to read user manuals, then we just urge you to
at least glance at the Instant Setup section. After glanc-
ing at or reading through the manual (we applaud you if
you do read the entire manual), please store it in a place
that is easy for you to nd, because chances are there’s
something you missed the rst time around.

GETTING STARTED
1. Ensure all power is turned off on your mixer.
To totally ensure this, the AC cable should not be
connected to the unit.
2. All faders and level controls should be set at the
lowest level and all channels muted to ensure
no sound is inadvertently sent through the
outputs when the device is switched on. All levels
can be altered to acceptable degrees after the
device is turned on using the channel setup
instructions.
3. Plug any necessary equipment into the device’s
various outputs. This could include ampliers and
speakers, monitors, signal processors, and/or
recording devices.
4. Plug the supplied AC cable into the AC inlet on the
back of the device and then into a power outlet of a
suitable voltage.
5. Turn the power switch on and follow the channel setup
instructions to get the most out of your equipment.
CHANNEL SETUP
1. To ensure the correct audio level of the input channel
is selected, each of the level input controls of the
Mixer should be turned counterclockwise or down as
far as they will go.
2. No input other than the one being set should have
any device plugged in. This will ensure the purest
signal is used when setting channels.
3. Set the level and AUX 1 controls of the channel you
are setting to the 0 dB mark. Also set the Main L-R
fader to the 0 dB mark.
4. Press down the AUX 1 button on the control room
source section, allowing the level meter to display
the level of the channel being set.
5. Ensure the channel has a signal sent to it similar to
the signal that will be sent when in common use. For
example, if the channel is using a microphone,
then you should speak or sing at the same level
the performer normally would during a performance;
if a guitar is plugged into the channel, then the guitar
should also be strummed as it normally would be (and
so on). This ensures levels are completely accurate
and avoids having to reset them later.
6. Set the gain so the Level Meter indicates the audio
level is around 0 dB.
7. This channel is now ready to be used; you can stop
making the audio signal.
8. You can repeat the same process for other channels.
Or not, it’s your call.

MAKING CONNECTIONS
Inputs and Outputs
1. XLR Microphone Jacks
These jacks accept typical 3-pin XLR inputs for balanced
and unbalanced signals. They can be used in conjunction
with microphones – such as professional condenser,
dynamic or ribbon microphones - with standard XLR
male connectors, and feature low noise preampliers,
serving for crystal clear sound replication. The MU1202
and MU1202X mixers feature four standard XLR
microphone inputs for your convenience.
NB. When these inputs are used with condenser microphones, the Phantom Power
should be activated. However, when Phantom Power button is engaged, single ended
(unbalanced) microphones and instruments should not be used on the Mic inputs.
2. Line Inputs
This input accepts typical 1/4” TRS or TS inputs, for
balanced or unbalanced signals. There are various
numbers of these inputs depending which mixer you are
using. They can be used in conjunction with various line
level devices, such as keyboards, drum machines, electric
guitars, and a variety of other electric instruments.
3. Stereo Channels
The MU1202 and MU1202X mixer features a couple of
stereo channels, thrown in for maximum exibility. Each
of these stereo channels features two 1/4” TRS phone
jacks, for the addition of various line level input devices,
such as electronic keyboards, guitars and external signal
processors or mixers. These Stereo Channels can also
be used as Mono channels, where the signal from any
1/4" phone jack plugged into the Left stereo input will
cause the signal to be duplicated to the Right input due
to the miracle of jack normalizing. This does not work in
reverse, however.
4. Stereo AUX Return
These 1/4” TS inputs are for the return of audio to the
MU1202 and MU1202X mixer, processed by an external
signal processor. If really needed, they can also be used
as additional stereo inputs, with a level control located on
the face of the mixer. The Stereo AUX Return can also
accept Mono signals, where plugging the 1/4" phone jack
of any device into the Left input will cause the signal to
be duplicated to the Right input also. This does not work
in reverse, however.
MU1202

PHONIC CORPORATIONMU 1202/1202X USER’S MANUAL Page 6
MU 1202/1202X USER’S MANUALPHONIC CORPORATION Page 7
5. AUX / Effects Send
These 1/4” TS outputs may be used to connect to an
external digital effect processor, or even to an amplier
and speakers (depending on your desired settings), to
the mixer.
6. Main L and R Outputs
These two ports will output the nal stereo balanced line
level signal sent from the main mixing bus. The primary
purpose of these jacks is to send the main output to
external devices, which may include power ampliers
(and in-turn, a pair of speakers), other mixers, as well
as a wide range of other possible signal processors
(Equalizers, Crossovers, etcetera).
NB. When sending unbalanced signals from this output, a 1/4" TRS stereo plugs
must be used and have the ring-pin disconnected, as to avoid damaging this
mixer.
7. Control Room Outputs
These two 1/4” Phone Jack outputs feed the signal
altered by the CTRL RM / PHONES level control (Or
CTRL RM / SUBMIX level control on the MU1202X) on
the face of the mixer. This output has extensive use, as it
can be used to feed the signal from the mixer to an active
monitor, for the monitoring of the audio signal from within
a booth, among other possible uses.
8. Phones
This stereo output port is suited for use with headphones,
allowing monitoring of the mix. The audio level of this
output is controlled using the CTRL RM / PHONES
level control (Or CTRL RM / SUBMIX level control on
the MU1202X).
9. Record Out
These outputs will accommodate RCA cables, able to be
fed to a variety of recording devices. Also included is a
mini stereo jack for the addition of recording devices such
as MD players, and even laptop computers, as well as a
Trim control, allowing users to control the output signal
level, ensuring total control over recording quality.
10. 2T Return
These RCA and mini stereo inputs are used to connect
the mixer with external devices, such as tape and CD
players, or even Laptop computers, receiving a signal
from another source and feeding it to the Main L-R
mixing bus.
MU1202X

Rear Panel
11. Foot Switch Jacks (MU 1202X only)
These ports are for the inclusion of a foot switch, used
to remotely adjust properties of the built-in Digital Effect
processor, to the mixer. The left jack is used to adjust
the tap delay properties, where the right jack is used for
turning the effects on and off.
12. ALT 3-4 Output (MU 1202X only)
The signal sent from these outputs is fed from the ALT
3-4 mixing bus, and can be used in conjunction with
a large array of devices, including signal processors,
other PA systems, recording devices, and so on.
13. Channel Inserts (MU 1202X only)
Located on the rear of the MU1202X, the primary use
for these TRS phone jacks is for the addition of external
devices, such as dynamic processors or equalizers, to
mono input channels 1 through to 4. This will require a Y
cord that can send (pre-fader and pre-EQ) and receive
signals to and from an external processor.
14. Power Connector
This port is for the addition of a power cable and supply,
allowing power to be supplied to the mixer. Please use
the external power supply that is included with this
mixer only.
CONTROLS AND SETTINGS
Rear Panel
15. Power Switch
This switch is used to turn the mixer on and off. Ensure
you turn all level controls down before activating.
16. Phantom Power Switch
When this switch is in the on position, it activates +48V
of phantom power for all microphone inputs, allowing
condenser microphones (well, the ones that don’t use
batteries) to be used on these channels. Activating
Phantom Power will be accompanied by an illuminated
LED above the left channel Level Meter. Before turning
Phantom Power on, turn all level controls to a minimum
to avoid the possibility of a ghastly popping sound
from the speakers. The MU1202X's Phantom Power
switch is located on the rear of the device, whereas the
MU1202's Phantom Power switch is located on the front
panel.
NB. Phantom Power should be used in conjunction with balanced microphones.
When Phantom Power is engaged, single ended (unbalanced) microphones and
instruments should not be used on the Mic inputs. Phantom Power will not cause
damage to most dynamic microphones, however if unsure, the microphone’s user
manual should be consulted.
MU1202X
MU1202

PHONIC CORPORATIONMU 1202/1202X USER’S MANUAL Page 8
MU 1202/1202X USER’S MANUALPHONIC CORPORATION Page 9
22. AUX 1 (Monitor) Control
This control allows the user to send the corresponding
signal to the AUX 1 output, which can be used in
conjunction with an amplifier and studio or stage
monitors, or simply as an auxiliary output for any means
required. The control is pre-fader, therefore any changes
made to the corresponding channel level control (27) do
not affect the AUX 1 send signal.
23. AUX 2 (Effects) Control
This control alters the signal level that is sent to the AUX
2 (or EFX) send output, which can be used in conjunction
with external signal processors (this signal of which can
be returned to mixer via the AUX return input, or any
stereo input channel), or simply as an auxiliary output for
any means required. This control is post-fader, therefore
any changes made to the corresponding channel level
control (27) are also applied to the EFX signal.
24. Pan / Balance Controls
This alternates the degree or level of audio that the left
and right side of the main mix should receive. On mono
channels, this control will adjust the level that the left and
right should receive (pan), where as on a stereo channel,
adjusting the BAL control will attenuate the left or right
audio signals accordingly (balance).
25. Mute / ALT 3-4 (MU1202X Only)
This handy little button is basically a typical
mute button – effectively stopping any
signal received by the channel from being
sent to the Main L/R mixing bus – however
it does so much more. Pushing this button
routes the channel’s signal away from the
Main L/R and to its own “Alternative” stereo
output, where the signal can be used at
will. If you wish to use it to connect an
amplier and speakers, or simply patch it
through to an unused input channel, you
can easily do so.
26. Peak Indicator
This LED indicator will illuminate when
the device hits high peaks, 6 dB before
overload occurs. It is best to adjust the gain
of the channel so that the PEAK indicator
lights up on intervals only. This will ensure
a greater dynamic range of audio.
27. Level Control
This rotary control will alter the signal level
that is sent from the corresponding channel
to the main mixing bus.
Channel Controls
17. Low Cut Filter (75 Hz)
This button, located on channels 1 through to 4, will
activate a low-cut / high-pass filter that reduces all
frequencies below 75 Hz at 18 dB per Octave, helping to
remove any unwanted ground noise or stage rumble.
18. Line / Mic Gain Control
This controls the sensitivity of the input signal of the
Line/Microphone input. The gain should be adjusted
to a level that allows the maximum use of the audio,
while still maintaining the quality of the feed. This can
be accomplished by adjusting it to a level that will allow
the peak indicator occasionally illuminate. All 4 mono
channels on the MU1202 and MU1202X feature this
control.
19. High Frequency Control
This control is used to give a shelving boost or
cut of ±15 dB to high frequency (12 kHz) sounds.
This will adjust the amount of treble included in
the audio of the channel, adding strength and
crispness to sounds such as guitars, cymbals,
and synthesizers.
20. Middle Frequency Control
This control is used to provide a peaking style
of boost and cut to the level of middle frequency
(2.5 kHz) sounds at a range of ±15 dB. Changing
middle frequencies of an audio feed can be
rather difficult when used in a professional
audio mix, as it is usually more desirable to
cut middle frequency sounds rather than boost
them, thereby soothing overly harsh vocal and
instrument sounds in the audio.
21. Low Frequency Control
This control is used to give a shelving boost or
cut of ±15 dB to low frequency (80 Hz) sounds.
This will adjust the amount of bass included in
the audio of the channel, and bring more warmth
and punch to drums and bass guitars.

PHONIC CORPORATIONMU 1202/1202X USER’S MANUAL Page 10
MU 1202/1202X USER’S MANUALPHONIC CORPORATION Page 11
28. +4 / -10 Switch (MU1202X only)
This button, located on both stereo input channels, is
used adjust the input sensitivity of the corresponding
channels, which will adapt the MU1202X to external
devices which may use different operating levels. If the
input source is -10 dBV (consumer audio level), it is best
to engage the switch, allowing the signal to be heard. The
+4 dBu level is suitable for Professional Audio signals,
which are considerably higher than the consumer level.
However, if you are unsure
of the source’s operating
level, we suggest leaving
the switch disengaged
until you test the source’s
signal. You can then
engage if necessary (if the
level of the input signal is
obviously too low).
Digital Effect Section (MU 1202X only)
29. Digital Effect Display
This panel displays the titles of different effects that can
be added to your audio signal. When you select the effect
number with the Program Control, the corresponding
effect is applied automatically. For a list of available
effects, please observe the Digital Effect Table.
30. Program Control
This control is used to scroll through the various effects
shown on the Digital Effect Display. Turning the control
will automatically change the effect and apply it to the
EFX RTN 2 feed.
31. Parameter Control
This will adjust the appropriate one main parameter of
the digital effect that is applied to the audio feed.
32. DSP Effect On and Indicator
This button is pushed to turn the corresponding effect
panel on or off. When the effect processor is turned on,
the corresponding LED illuminates.
33. Peak Indicator
This LED indicator will illuminate when the DSP is
overdriven and causes distortion. It is best to adjust
the AUX 2 / EFX Send fader so as to ensure the PEAK
indicator does not light. This will ensure a greater dynamic
range for audio.
34. Tap Delay and Indicator
When the tap delay effect is selected, this button is
used to determine the delay time. By pushing the button
several times, the mixer interprets the time between
last two pushes and remembers this as the delay time,
until the button is pushed again (this is kept, even after
the power is turned off). When the tap delay effect is
selected, the corresponding LED will ash at the intervals
selected.
Master Section
35. AUX Stereo Return Controls
MU1202: These controls adjust various properties of the
ST Rtn signals. The AUX 1 control adjusts the level that
is sent to the monitor mixing bus, where as the Level
control adjusts the level that is sent to the Main L/R mixing
bus. The BAL control will attenuate the left or right audio
signals accordingly.
MU1202X: These controls adjust the signal level of
audio fed through to the AUX
Stereo Return inputs, which
will be added to the MAIN
L-R mix. The AUX Return 2
control also acts as the built-
in DSP Effect level control,
when no device is plugged
into the AUX 2 Return jacks.
36. AUX Stereo Return “to AUX 1” Send Controls
These two rotary controls are used to adjust the audio
signal received by the AUX Return 1 and 2 jacks, which
is sent to the AUX 1 Send output. These act as an "effect
to Monitor" control, allowing performers/engineers to hear
the signal processed by either external devices or the
Internal DSP Effect Engine.

PHONIC CORPORATIONMU 1202/1202X USER’S MANUAL Page 10
MU 1202/1202X USER’S MANUALPHONIC CORPORATION Page 11
37. Control Room Source Buttons
Engaging any of these four buttons will enable you to
use the signal from any of the corresponding sources
to send to the Control Room mixing bus and the
LED Level Meter for level monitoring. For instance,
pressing 2T Rtn button will allow you to send the 2
Track Return signal to the Control Room Outputs
and Level Meter, where as the Main
L-R will allow you to use the Main
Left/Right signal instead, the AUX 1
allows you to use the AUX 1 signal
and the ALT 3-4 allows you to use
the addition stereo mix bus signal.
You can even use a combination of
all these signals, if need be.
On the MU1202, you can choose to
send either the AUX 1 (Stereo), AUX
2, Main or 2T Return signals to the
Control Room.
38. Assign To Main Button
(MU1202X Only)
When the "Assign To Main" button
is engaged, the 2T Return and
Alternative 3-4 signals can be selected
by using the corresponding buttons,
and are, intern, sent to the Main L-R
and Control Room mixing buses via
the Control Room / Submix control.
This can come in handy when you
want play a CD during intermission
in a live show. If you have the Main
L-R or AUX 1 buttons on the Control
Room Source section engaged, the
corresponding signals will not be sent
to the Main L-R by way of this button,
nor will their signals be sent to the
Control Room or Phones outputs.
39. Ctrl Rm / Submix Control /
Phones
This control is used to adjust the audio
level of the Control Room feed, which
is sent to both the Control Room
outputs (for monitoring, acting as side
fill or other purposes) and Phones
outputs (to be used in conjunction with headphones for
monitoring purposes). On the MU1202X it also acts as
the "submix" control, which allows the user to adjust the
signal selected by the Control Room Source when the
Assign to Main button is engaged.
40. 2T Return Control and "to Main"
button (MU1202 Only)
This control adjusts the signal level
received by the 2T Return inputs, that
is sent to the Control Room Source
section. Using the "to Main" button will
do just that: send the 2T Return signal
to the Main L-R mixing bus.
41. Record Out Trim Control
The MU1202's Record Out Trim Control
allows users to set the level of the Rec
Out outputs to that which allows clear,
quality recording on all recording
devices. The MU1202X also features
trim control on the Record Out outputs,
located by the Rec Out jacks.
42. Main L-R Control
This 60mm fader is nal level control for
the main left and right audio feed, sent
to the Main L and R output.
43. Level Meter
The MU1202 and MU1202X’s
stereo 10-segment level meters
give an accurate indication of when
audio levels from the Control Room
Matrix Source reach certain levels.
It is suggested for the maximum use
of audio to set the various levels
controls so that the Peak LEDs ash
only occasionally (and perhaps it is
better if you ensure the level stays
around a pinch below that).
44. +48 Indicator
The +48 Indicator illuminates
whenever the Phantom Power
switch is activated.
45. Power Indicator
The Power Indicator will light up
when the power of the mixer is on;
in case you weren’t too sure.
46. AUX 1 and 2 Send Master Controls (MU1202 Only)
These controls adjust the nal signal level from the
AUX 1 (MONI) and AUX 2 (EFX) mixing buses to the
corresponding AUX 1 and 2 output jacks.
