Introduction
Thank you for choosing one of Phonic’s many
quality compact mixers. The brand new AM642D,
AM642DP and AM642D USB mixers – designed
by the ingenious engineers that have created a
variety of mixers fantastic in style and performance
in the past – display similar prociency that previous
Phonic products have shown; with more than a few
renements, of course. Featuring full gain ranges,
amazingly low distortion levels, and incredibly wide
dynamic ranges, these amazing mixers are bound to
make a big splash in the world of mixing.
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 glancing 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.

Computer Connection (USB Model)
By simply connecting the USB cable provided along
with your AM642D USB to the device and your
Personal Computer or Laptop, you are able to send
CD quality (16-bit stereo, with a 44.1 kHz sampling
rate) signal to and from your mixer. By doing this, you
are actually turning your mixer into a highly useful
plug’n’play soundcard for your computer.
The USB sends an audio stream of the Main Left
and Right (record out) signal of your mixer to the
computer. You can use almost any dedicated Digital
Audio Workstation (DAW) software to record the
signal from the AM mixer. You can also set the mixer
as your default audio device.
The USB interface also returns the audio signal from
your computer back to the 2T Returns, the signal of
which is controlled by the 2T / USB Return control. If
there are input signals from both the USB interface
and the 2T Return, the two signals are combined and
controlled simultaneously by the 2T return control.

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 switched off 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.
3. Plug all necessary instruments and equipment
into the device’s various inputs as required.
This may include line signal devices, such as
keyboards and drum machines, as well as
microphones and/or guitars, keyboards, etc.
4. Plug any necessary equipment into the device’s
various outputs. This could include ampliers and
speakers, monitors, signal processors, and/or
recording devices.
5. Plug the supplied AC cable into the AC inlet on
the back of the device and a power outlet of a
suitable voltage.
input channel is selected, each of the Mixer’s
Channel’s ON buttons should be disengaged
(which should turn the corresponding LED
indicator off – otherwise go back and try again),
as well as the SOLO buttons on each channel,
and make sure that the 2T RTN knob is all the
way down.
2. Ensure the channel you wish to set has a
signal sent to it similar to the signal that will be
sent when in common use. For example, if the
channel has a microphone connected to it, 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.
3. Move the Channel fader and Master L/R faders
to around the 0 dB mark.
4. Turn the Channel ON.
5. Pushing the channel’s SOLO button and releasing
the Pre/Post button on the CTRL RM section will
send the pre-fader signal of the activated channel
to the Control Room / Phones mixing bus and
the Level Meter will display the Control Room’s
signal properties.
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 now repeat the same process for other
channels if you wish.
6. Turn the power switch on.

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 preampliers, serving for crystal clear sound
replication. The AM642D mixers feature a total of six
XLR microphone inputs.
NB. When these inputs are used with condenser microphones,
the Phantom Power should be activated. However, when Phantom
Power 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 balanced or
TS unbalanced inputs, for balanced or unbalanced
signals. They can be used in conjunction with a wide
range of line level devices such as keyboards, drum
machines, electric guitars, and a variety of other
electric instruments. These inputs are found at the rear
of the AM642D USB.
3. Stereo Channels
The AM642D mixers also feature a few stereo
channels, thrown in for maximum exibility. Each
of these stereo channels features two 1/4” phone
jacks, for the addition of various line level input
devices, such as electronic keyboards, guitars and
external signal processors or mixers. If you wish
to use a monaural device on a stereo input, simply
plug the device’s 1/4” phone jack into the left (mono)
input and leave the right input bare. The signal will
be duplicated to the right due to the miracle of jack
normalizing. The AM642D mixers feature four stereo
channels and include a +4/-10dB selector switch for
a maximum exibility.
4. AUX Returns
These 1/4” TS inputs are for the return of audio to
the AM642D mixers, processed by an external signal
processor. If really needed, they can also be used as
additional inputs. The feed from these inputs can be
adjusted using the AUX Return controls on the face
of the mixer. When connecting a monaural device to
the AUX Return 1 and 2 inputs, simply plug a 1/4”
phone jack into the left (mono) input, and the signal
will appear in the right as well. This, however, does
not work for the AUX Return 2 input on all AM642D
mixers. When the AUX Return 2 is used, the built-in
digital effects processor is automatically by-passed.
5. AUX Sends
These 1/4” TS outputs may be used to connect to
an external signal processor, or even to an amplier
and speakers (depending on your desired settings)
from the mixer. The signal from the AUX Sends is
controlled by the AUX master controls (on the face
of the mixer), which obtain their signal from the AUX
controls located on each channel strip. The AM642D
mixers feature a total of 3 AUX sends.
6. Foot Switch Jacks
This port is for the inclusion of a foot switch, used
to remotely turn the Digital Effects Processor on
and off.
English
7. 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
Control Room / Phones control.
3AM642D / AM642DP / AM642D USB
8. Record Out
These outputs will
English
accommodate RCA
cables, able to be fed
to a variety of recording
devices.
9. 2T Return
These RCA inputs are
used to connect the mixer
with external devices,
such as CD, Tape and
Cassette Players.
10. Main Out
These two XLR jacks will
output the final stereo
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
ampliers (and in-turn, a pair of speakers), other
mixers, as well as a wide range of other possible
signal processors (Equalizers, Crossovers, etcetera).
Rear Panel
11. Channel Inserts
Located on the rear of the mixer, 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 6 on the AM642D
mixers. This send and return will require a Y cord
that can send (pre-fader and pre-EQ) and receive
signals to and from an external processor.
12. Control Room Outputs
These two 1/4” phone jack outputs feed the signal
altered by the Control Room / Phones level control
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, or, alternatively, for
the addition of external signal processing devices
or mixers, as well as acting as a “side ll” output,
supplying audio to indoor areas that the main
speakers do not reach.
13. Group Out
These 1/4” phone jacks output the nal feed from
the Group 1 and 2 Faders on the main mixer. These
outputs can be used to feed a wide range of devices,
such as mixers, signal processors, and even to
connect an amplier and speakers to be used along
with the Main Speakers, for a more rounded audio
experience.
14. Main Out
These two XLR ports will output the nal stereo
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 ampliers (and in-turn, a pair of speakers),
other mixers, as well as a wide range of other
possible signal processors (equalizers, crossovers,
etcetera).
4 AM642D / AM642DP / AM642D USB
15. Power Connector
This port is for the addition of a power cable, allowing
power to be supplied to the mixer. Please use the
power cable that is included with this mixer only.
Controls and Settings
Rear Panel
Channel Controls
18. Low Cut Filter (75 Hz)
This button will activate a high-pass lter that reduces
all frequencies below 75 Hz at 18 dB per Octave,
helping to remove any unwanted ground noise or
stage rumble. This Low Cut Filter is only available
on Mic channels.
English
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.
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. If unsure, however, the
microphone’s user manual should be consulted.
17. Power Switch
This switch is used to turn the mixer on and off.
Ensure you turn all level controls down before
activating.
19. 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.
20. 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.
21. Middle Frequency Control
This control is used to provide a peaking style of
boost and cut to the level of middle frequency sounds
at a range of ±15 dB. These mixers also provide
a sweep control, allowing you to select a center
frequency between 100 Hz and 8 kHz. Changing
middle frequencies of an audio feed can be rather
difcult when used in a professional audio mix, as
it is usually more desirable to cut middle frequency
sounds rather than boost them, soothing overly harsh
vocal and instrument sounds in the audio.
The stereo channels feature High-Mid and Low-Mid
controls instead of the typical controls described
above. They provide a peaking style of boost and cut
to middle frequencies, where the frequencies are set
at 3 kHz and 800 Hz, respectively.
22. 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.
23. AUX Control
This control alters the signal level that is being sent
to the auxiliary 1 mixing bus, the signal of which
is suitable for connecting stage monitors, allowing
artists to listen to the music that is being played.
Also included is a Pre/Post button which alternates
the feed to the AUX mixing bus between a post and
pre-fader feed.
5AM642D / AM642DP / AM642D USB
24. EFX Control
This control alters the signal level that is sent to the
English
EFX send (AUX 3) output and the built-in digital
effect processor. The EFX send signal can be used
in conjunction with external signal processors (this
signal of which can be returned to mixer via the AUX
return input), or simply as an additional auxiliary
output.
25. Pan / Balance Controls
This alternates the degree or level of audio that the
left and right side of the main mix should receive. On
Mic channels, the PAN 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).
26. On Button and
Indicator
This turns the channel
on, allowing the user to
use the feed from the
channel’s inputs to supply
the MAIN L/R, GROUP 1/2,
AUX and EFX buses. The
corresponding indicator
will be illuminated when
turned on.
27. 1-2 and L/R Buttons
These handy buttons allow you to decide the audio
path of the corresponding channel. Pushing the “12” button allows the signal to be sent to the Group
1-2 mix, where the “L/R” allows it to be sent to the
Main L/R mix.
30. Level Faders
These faders allow users to adjust the level of the
signal from the corresponding input channel that is
to be sent to the destinations selected by the 1-2
and L/R buttons.
Digital Effect Processor
31. Program Control
This rotary control allows users to select the digital
effect program of your choice. There are 16 points
on the rotary control, each of which corresponds with
an effect type. See the digital effect table for more
information.
32. Parameter Control
Turning this control will adjust the one main parameter
of the selected effect. Each effect’s parameter can
be found on the digital effect table.
33. Effect On Button
This button is pushed to turn the corresponding effect
panel on or off. Effects can also be disabled by using
a footswitch with the jack on the rear of the mixer.
Please note: this button will not lock down as similar
buttons on the mixer do.
31 32

28. Peak Indicator
This LED indicator will illuminate when the channel
hits high peaks, 6 dB before overload occurs. It is
best to adjust the channel level control to a level
slightly prior to the peak indicator does not light up.
This will ensure a greater dynamic range of audio.
This indicator also doubles as a Solo indicator, when
the SOLO button is engaged.
29. Solo Button
The Solo button is pushed to allow the signal of a
corresponding channel to be sent to the Control
Room / Phones control. The signal is either that of a
pre- or post-fader depending on the pre/post button
in the master section.
6 AM642D / AM642DP / AM642D USB
Master Section
34. AUX Return Controls
These controls adjust the signal level of audio fed
through to the stereo AUX Return inputs. The “To AUX
1” control adjusts the pre-fader level of the signal from
the AUX Return inputs to the AUX 1 mixing buses.
35. EFX Return (AUX Return 2) Control
This control adjusts the signal level of audio fed
through to stereo AUX Return 2 inputs. If no device
is plugged into the AUX Return 2 inputs, this control
then acts as the nal level control of the built-in Digital
Effect Engine.
36. Main L/R and Group 1-2 Buttons
The EFX Return control is accompanied by Main L/
Rand Group 1-2 buttons. These buttons change the
destination of the EFX Return signal between the
Main L/R signal and/or Group 1-2 sub mix.
37. Return Solo Buttons
Pushing either of the Return Solo buttons allows
users to send the signal from the AUX Returns 1
and/or 2 to the Control Room / Phones mixing bus.
38. AUX Send Master Control
This control adjusts the nal level of the AUX mixing
bus (as taken from the AUX level controls on each
channel strip), the audio of which is sent to AUX Send
output. The corresponding SOLO button allows you
to send the AUX Send signal to the Control Room /
Phones mixing bus. The AM642D mixers feature 3
sends, where the rst is in fact a 60mm fader, rather
than the simple rotary control. Also incorporated with
the AUX 1 control of the AM642D mixers is a Peak
LED, as well as an ON button and indicator, allowing
AUX 1 to be activated and muted when required.
Activation of AUX Send 1 is, of course, accompanied
by an illuminated LED.
39. EFX Send Master Control
This control adjusts the nal level of the EFX mixing
bus (as taken from the EFX level controls on each
channel strip), the audio of which is sent to the AUX
Send 3 outputs, as well as the built-in digital effect
engine. The corresponding SOLO button allows you
to send the signal to the Control Room / Phones
mixing bus.
40. Control Room / Phones Controls
This control is used to adjust the audio level of the
Phones feed, as well as the signal sent to the Control
Room output, for use in monitoring and tracking of
audio.
