AM2442FX / AM3242FX
Subgroups
The Subgroups on the AM mixers allow users to create single
mono or stereo mixes of multiple input channels and control them
with a single fader. It is also common to use the Group outputs as
tape-outputs for connecting to multi-track recorders.
24. Solo Buttons
The solo button allows the Group signal to
be sent pre or post fader (depending on the
SOLO/PFL button settings) to the Control
Room / Phones mix, allowing users to be
able to monitor the subgroup signal. When
activated, the Solo LED will light up to
indicate as such.
25. Left / Right Buttons
The Group Controls also feature individual
left and right buttons, which allow you to send
the various Group signals to the Main Left
and Right. This can be handy when wanting
to combine the signals from different signals
and control their input levels simultaneously,
then send them to the Main L/R signal (eg.
when multiple inputs are used for, say,
drums, you can combine these inputs together to be controlled
much simpler by a single fader).
26. Faders
These four faders are the final level control for the Group 1 to 4
audio feeds, sent to the corresponding Group outputs on the rear of
the AM mixers to feed external devices such as effect processors,
and, most commonly, multi-track recorders. The Group mix can be
fed a signal from the various mono and stereo channels, as well
as the EFX signal, depending on your selections. When pushed all
the way up, these faders provide 10 dB of gain to the signal, and,
when set all the way down, effectively mute the signal.
27. Group Outputs
These 1/4” phone jacks output the final
feed from the Group mixes 1, 2, 3 and
4, the level of which is determined by
the Group Faders. They can be used
to feed a variety of recording and PA
devices, including multi-track recorders,
amplifiers and speakers, etc.
Mono / Subwoofer Channel
The Mono output is used as an auxiliary
output (the signal of which is taken from
the main mix), and can be connected to an
amplifier and speakers. The included low
pass filter enables the signal of the mono
output to be more appropriate for use with a
subwoofer speaker, to add a little extra bass
to your sound.
28. Low Pass Filter
The low pass filter is activated by moving the
small slide switch to the ON position. The
accompanying control allows users to adjust
the cut-off frequency of the filter. If users wish
to use the Mono channel for monitoring or
other similar purposes, the low pass filter
should not be activated.
29. Mono Fader
This fader controls the level of the mono
signal that is sent to the mono outputs.
30. Mono Output
The line-level signal sent from the Mono output
can be used to connect to an amplifier or active
speaker. It is also possible to use this output
for monitoring purposes, with headphones or
active monitors.
Talkback Section
Handy in studios or on stage, the talkback function built into the
AM mixers allows engineers or producers – anyone, really – to
communicate with the performers wherever they may be.
31. Talkback Level Control
This control adjusts the level of the talkback
signal that is sent to the AUX 1 and AUX
2 outs.
32. Talk to AUX Button
Holding this button down activates the AM’s
built-in talkback microphone, the signal of
which is sent to the AUX 1 and 2 outputs.
Keep the button pushed down until you
finish speaking.
33. Talkback Mic
Point your mouth here when wishing to communicate with the
performer/musician.
Control Room & Phones
The Control Room and Phones mixes are useful for monitoring of
audio signals. It is important to remember, particularly when using
headphones, that listening to excessively loud audio signals for
prolonged periods of time could adversely affect your hearing.
34. Level Control
This rotary control will allow users to adjust the audio level of the
Control Room / Phones signal (as received by input channels, and
those chosen by the Source Select buttons). If active monitors are
used with the Control Room / Phones output, then this control acts
as the monitor level control.
35. Source Select
This set of buttons allows users to select which signals they wish
to send to the Control Room / Phones output. There is a button
each for the AUX 1/2, CD/Tape, 1-2, 3-4 and Main mixes. These
signals can be monitored simultaneously, if wished.
36. Control Room / Phones Output
This 1/4” outputs feeds the signal altered by the Control Room
/ Phones level control on the face of the mixer to an external
speaker or headphones. 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
many other possible uses.
