CONTROLS AND SETTINGS

Channel Controls

11. Line/Mic Gain Control
This controls the sensitivity of the input signal of the Line/Micro-
phone 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.
12. 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.
13. 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.
14. 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.
15. Low Cut Filter (75 Hz)
This button, located on channels 1 through to 4, will activate a
low-cut / 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.
16. AUX/EFX Control
The AUX or EFX control alters the signal level that is sent to
the AUX/EFX mix. In the case of the AM440D, AM440W and
AM440DP, this signal makes its way to the built-in Digital Effects
Processor and is in-turn sent through the EFX send output.
These controls are pre-fader, therefore any changes made to the
corresponding channel level controls are not applied to the AUX
or EFX signals.
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), where as on a
stereo channel, adjusting the BAL control
will increase the left or right audio signals
accordingly (balance).
18. Level Control
This rotary control will alter the signal level
that is sent from the corresponding channel
to the main mixing bus.

19. 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.
20. +4 / -10 Switch
This button, located on all stereo channels,
is used adjust the input sensitivity of the
corresponding channels, which will adapt
the AM440 mixers to external devices
which may use different operating levels.
If the input source is -10 dBV (consumer
audio level), it is best to engage the switch,
allowing the signal to be heard. The +4
dBu level is suitable for Professional Audio
11
signals, which are considerably higher than the consumer level.
However, 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 the input
signal is obviously too low).

21. Program Control
This rotary control allows users to select
14
the digital effect program of your choice.
There are 16 points on the rotary control,
each of which corresponds with an effect
15
type. See the digital effect table for more
information.
22. Parameter Control
Turning this control will adjust the one main
parameter of the selected effect. Each
effect's parameter can be found on the
digital effect table.
23. EFX "to Main" Control
This will adjust the level of the Digital Effect signal that will be
sent to the Main left and right mixing bus to be applied to your
main feed.
24. EFX "to Ctrl" / EFX "to Phone" Button
On the AM440D and AM440W, this button is pushed to allow the
signal from the Digital Effect processor to be sent to the Control
Room outputs for monitoring purposes. This same button on the
AM440DP will send the effect signal to the headphones mix only.
