CONTROLS AND SETTINGS

Channel Controls

12. Mic/Line Gain Control
This controls the sensitivity of the
input signal of the line/microphone
inputs. The gain should be adjusted
to a level that allows the maximum
use of the audio, while still maintain-
ing the quality of the feed. This can
be accomplished by adjusting it to a
level that will allow the peak indicator
occasionally illuminate. The AM120
MKIII features a single gain control
for channel 1, located on the face of the mixer, whereas
the AM220 and AM220P features a gain control on both
channels 1 and 2 located directly below the line inputs.
13. High Frequency Control
This control is used to give a shelv-
ing 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 syn-
thesizers.
14. Middle Frequency Control
(AM220 / AM220P)
This control is used to provide a
peaking style of boost and cut to
the level of the 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
– soothing overly harsh vocal and instrument sounds in
the audio. The middle frequency control is featured on the
AM220 and AM220P. The AM120 MKIII features high and
low frequency controls only.
15. 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.

16. AUX Control (AM220 / AM220P)
These controls, found on each input channel, determines
the level of the current channel that is sent to the AUX send
output. This signal can be used in conjunction with external
processors or for any other auxiliary application. The signal
can then be returned from processors via the AUX return
inputs. This control is post-fader, therefore any channels
made to the corresponding channel fader are also applied
to the EFX signal. This control is featured on the AM220
and AM220P only.

17. 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, this control will adjust the level that the left and
right should receive (pan). On a stereo channel, adjusting
the BAL control will attenuate the left or right audio signals
accordingly (balance). Every model features a PAN or BAL
control on each of their channel strips.

18. Peak Indicator
14 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
15
up on intervals. This will ensure a greater dynamic range
of audio. The AM120 MKIII features a peak indicator on
16
channel 1 only, while the AM220 and AM220P feature a
peak indicator on channels 1 and 2.

19. Level Control
18
This control will alter the signal level that is sent from the
19
corresponding channel to the main mix.
