CONTROLS AND SETTINGS

Channel Controls

12. Line/Mic Gain Control
This controls the sensitivity of the inputsignal
of 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. 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 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, AM105, AM105FX, 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.
Effects Section
22. Effects On Button (AM105FX and AM125FX only)
Pushing this button will turn the built-in effect processor on and
off.
23. Variation Control (AM105FX and AM125FX only)
This LED indicator will illuminate when the EFX signal hits high
peaks, just before overload occurs. It is best to adjust the EFX
to Main control so as to ensure the Peak indicator does not light
up.
