CONTROLS AND SETTINGS

Channel Controls

12. Line/Mic Gain Control
This controls the sensitivity of the
inputsignal of the Line/Microphone
i n p u t . T h e g a i n s h o u l d b e
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
w i l l a l l o w t h e p e a k i n d i c a t o r
occasionally illuminate. The AM55 features a single
gain control for channel 1, located on the face of the
mixer, whereas the AM85, AM105 and AM105FX
all feature gain controls on both channels 1 and 2,
located directly below the Line inputs. The AM125
and AM125FX feature gain controls on channels 1
through 4.
13. 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.
14. Low Cut Filter (75 Hz) (AM85, AM105,
AM105FX, AM125 and AM125FX only)
This button will activate a high pass filter that
reduces all frequencies below 75 Hz at 18 dB per
octave, helping to remove any unwanted ground
noise or stage rumble. This button can be found on
mono channels of the AM85, AM105, AM105FX,
AM125 and AM125FX only.
15. Middle Frequency Control (AM85, AM105
and AM105FX only)
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. 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.

16. 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
11
channel, and bring more warmth
and punch to drums and bass
guitars.
17. AUX/EFX Control (AM85,
AM105, AM105FX, AM125
and AM125FX only)
These controls alter the signal
level that is sent to the AUX or
EFX Sends, which can be used
in conjunction with external signal
processors, or simply as an auxiliary output for any
means required. On the AM105FX and AM125FX,
the EFX control is used to alter the signal level that is
sent to the internal effects mix.

18. +4 / -10 Switch (AM85,
A M 1 0 5 , A M 1 0 5 F X ,
AM125 and AM125FX
only)
This switch is used adjust
the inputsensitivity of the
corresponding channels, which will adapt the mixer
to external devices which may use different operating
levels. If the inputsource is -10 dBV, it is best to
engage the switch, allowing the signal to be heard.
The +4 dBu mode is suitable for use with professional
audio level signals, which are considerably higher
than the consumer level. If you are unsure of the
source's operating level, we suggest leaving the
switch disengaged until you test the source's signal.
You can then engage if necessary (if the level of
input is obviously too low).
19. 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), where as
on a stereo channel, adjusting the BAL control will
attenuate the left or right audio signals accordingly
(balance). Each model features a PAN or BAL control
on every one of their channel strips.
20. 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. This will ensure
a greater dynamic range of audio. The Peak indicator
is featured on the mono channels of every model.
21. Level Control
This control will alter the signal level that is sent from
the corresponding channel to the main mixing bus.
