21. Compressor Control and Indicator
This controls the onboard compressor
function on mono channels. Turning
this control up towards the 12 o'clock
position will adjust the threshold and
ratio of the compressor at varying
degrees. Once you reach the 12
o'clock position, the control will then
adjust the compression settings along
with an onboard expander (or, in other
words, a compander). The LED that
accompanies this control will light up
when the compressor is triggered.
22. 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.
23. 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 difficult
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 of the AM442D
USB and AM642D USB mixers feature
a High-Mid and Low-Mid
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 (High-Mid is set at 3 kHz
and Low-Mid is set at 800 Hz).
24. 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.
25. AUX Control and Pre/Post Button
This control alters the signal level that is being sent to the AUX 1
mix, the signal of which is suitable for connecting stage monitors,
allowing artists to listen to the music that is being playing. Also
included is a Pre/Post button, which alternates the feed to the
AUX mix between a post- and pre-fader feed. The AM642D USB
features a second AUX send mix, and thus offers a second AUX
control.

26. EFX Control
This control alters the
signal level that is sent to
the EFX send (AUX 2 or
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.
27. 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, 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).
28. 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.
29. 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.
30. 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 so as to allow the PEAK indicator to light
up on regular intervals only. This will ensure a greater dynamic
range of audio.
31. Solo Button
The Solo button is pushed to allow the signal of a corresponding
channel to be sent to the Control Room / Phones control (pre
or post fader, depending on the properties selected by the pre /
post button, located by the Control Room / Phones control), for
use with either headphones or studio monitors. This also allows
easier setting of the input gain and tracking of audio by sound
engineers. The corresponding green LED will illuminate when the
Solo button is engaged.
32. Channel Level Fader
This control will alter the signal level that is sent from the
corresponding channel to the main mixing bus.
