18. Gain Control
These controls, found on each input channel, allow users to
adjust the sensitivity of the input signal for 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 feature this control.

19. 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. This
control and indicator can only be found on mono channels of the
AM1204FX RW.
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 (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.
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 / EFX Controls
The AUX 1 and 2 controls allow the user to send the corresponding
signal to the AUX 1 and 2 mixes, the final levels of which are
controlled by the AUX Send controls on the main mixing panel.
These signals are then sent to the corresponding AUX Send
Outputs for use with amplifiers and studio or stage monitors, or
simply in conjunction with external processors. AUX 1 features a
pre-fader, pre-EQ signal, while AUX 2's signal is post-fader, post-
EQ. The AUX 2 control doubles EFX control on the AM1204FX
RW, adjusting the signal that is sent to the built-in Digital Effects
Processor.
24. Pan / Balance Control
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), whereas on a stereo channel, adjusting the BAL control
will increase the left or right audio signals accordingly (balance).

25. MAIN / ALT3-4 Button
This button turns a mute on the corresponding channel on and
off, stopping all audio from the channel input to the Main mix.
When a channel is muted, this audio – which would normally be
wasted – is redirected to the ALT 3-4 mix.
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, if at
all. This will ensure a greater dynamic range of audio.
27. Level Control
This 60mm fader will alter the signal level that is sent from the
corresponding channel to the main mix.
