5AM442D/AM642D
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
levelscanbealteredtoacceptabledegreesafter
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 ampliers 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.
6. Turn the power switch on.
Channel Setup
1. To ensure the correct audio level of the
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
performernormallywould duringa 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. Pushingthechannel’sSOLObuttonandreleasing
the Pre/Post button on the CTRLRM section will
sendthepre-fadersignaloftheactivatedchannel
to the Control Room / Phones mixing bus and
the Level Meter will display the Control Room’s
signal properties.
6. Setthegainsothelevelmeterindicatestheaudio
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 AM442D/AM642D
Making Connections
Inputs and Outputs
1. XLR Microphone Jacks
These jacks accept typical
3pin XLR inputs for balanced
and unbalanced signals. They
can be used in conjunction
with microphones–such as
professional condenser,
dynamicorribbonmicrophones
– with standard XLR male
connectors, and feature low
noise preampliers, serving for crystal clear sound
replication. The AM 442D mixer features four
standard XLR microphone inputs, whereas the AM
642D features a total of six.
NB. When these inputs are used with condenser microphones,
thePhantomPowershouldbeactivated.However,whenPhantom
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.
3. Stereo Channels
The AM 442D and AM 642D 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
andexternalsignal processors or mixers.Ifyou 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 AM 442D and AM 642D feature
fourstereochannelsandincludea+4/-10dBselector
switch for a maximum exibility.
4. AUX Returns
These 1/4” TS inputs are for the return of audio to
the AM 442D and AM 642D 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 theAUX 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 both AM442D/AM642D.When the AUX
Return2is used, the built-in digital effectsprocessor
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 amplier
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 theAUX
controls located on each channel strip. The AM
442D features 2 AUX sends, whereas the AM 642D
features a total of 3.
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.
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.

7AM442D/AM642D
8. Record Out
These outputs will
accommodateRCAcables,
able to be fed to a variety
of recording devices.
9. 2T Return
These RCA inputs are
used to connect the mixer
withexternaldevices,such
asCD,Tapeand 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 ampliers (and in-turn, a
pair of speakers), other mixers, as well as a wide
rangeofotherpossiblesignalprocessors(Equalizers,
Crossovers, etcetera).
Rear Panel
11. Channel Inserts
Located on the rear of the AM 442D and AM 642D,
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 on theAM 442D and 1 through 6 on the
AM 642D. 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
outputscan be usedto feed awiderange ofdevices,
such as mixers, signal processors, and even to
connect an amplier 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 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).

Rear Panel
16. Phantom Power Switch
When this switch is in the on position, it activates
+48V of phantom power for all microphone inputs,
allowingcondensermicrophones(well,the onesthat
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
levelcontrolsto a minimum to avoid thepossibilityof
a ghastly popping sound from the speakers.
NB. Phantom Power should be used in conjunction
with balanced microphones. When Phantom Power
isengaged,singleended(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.
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
stagerumble.This LowCutFilter isonly availableon
Mic channels on both the AM 442D and AM 642D.
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,
whilestillmaintainingthequalityof thefeed.Thiscan
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
thechannel,addingstrengthandcrispnesstosounds
such as guitars, cymbals, and synthesizers.
21. Middle Frequency Control
This control is used to provide a peaking style of
boostandcuttothelevelofmiddlefrequencysounds
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
difcult when used in a professional audio mix, as
it is usually more desirable to cut middle frequency
soundsratherthanboostthem,soothingoverlyharsh
vocal and instrument sounds in the audio.
The stereo channels feature High-Mid and Low-Mid
controls instead of the typical controls described
above.Theyprovideapeaking styleof boostand cut
tomiddle frequencies,where thefrequenciesare 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.

9AM442D/AM642D
24. EFX Control
This control alters the signal level that is sent to the
EFXsend(AUX 2 on theAM442D,AUX3 on theAM
642D) output and the built-in digital effect processor.
TheEFXsendsignalcanbeusedinconjunctionwith
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).

27. 1-2 and L/R Buttons
These handy buttons allow you to decide the audio
path of the corresponding channel. Pushing the “1-
2” 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.
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.
Thisindicatoralso doubles as aSolo 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.
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. Digital Effect Display
This 2-digital numeric display shows the program
number that is currently applied to your EFX audio
signal.WhenyourotatetheProgramcontrol,youcan
scroll through different program numbers; however
the display will revert back to the original program if
a new program is not selected within a few seconds.
