12. Mute Button and Indicator
Pushing the Mute button in will cut off
the main mix’s feed of the corresponding
channels signal. If the AUX pre/post
button is set to post, the AUX 1 and 2
signals will also be cut off. Muting an
input channel is accompanied by the
lighting up of the Mute LED.
13. Clip LED
This LED indicator will illuminate when
the channel hits high peaks, slightly
before the signal is dynamically clipped.
It is best to adjust the channel’s level
control so as to ensure the Clip indicator
does not light up. This will ensure a
greater dynamic range of audio. This
indicator also doubles as a Solo indicator,
when the Solo button is engaged.
14. Solo Button
The Solo button is pushed to allow the signal of the corresponding
channel to be sent to the Control Room / Phones mix (pre or post
fader, depending on the properties selected by the Solo/PFL button
located below the level meter), for use with either headphones
or studio monitors. This button also allows for easier isolation of
individual channel signals, enabling simpler setting of the input
gain or tracking of audio by sound engineers. When the Solo
button is not engaged, the LED indicator works as a Clip Indicator,
illuminating when the signal reaches high peaks.
15. 1-2 and 3-4 Buttons
These two buttons allow users to route the channel’s signal to
their respective subgroups. There are four subgroups in total.
If users wish to send the channel’s signal to, say, sub 1 but not
sub 2, simply use the channel’s pan (turn it hard to the left) to
accomplish this.
16. Main Button
Pushing this button in allows the channel’s signal to be sent to
the Main mix.
17. Channel Fader
This control will alter the signal level that is sent from the
corresponding channel to the corresponding mixing buses.
Stereo Input Channels
Stereo channels differ slightly to the mono channels in their
connections and controls. To follow you will find a run-down on the
differences and what these channels are actually good for.
18. Stereo Inputs
The AM mixers each feature 4 stereo input channels, the inputs of
which differ slightly to the mono channels.
The two 1/4” TRS inputs are for the addition
of various stereo line level input devices,
such as keyboards or drum machines. If you
wish to use a monaural device on a stereo
return input, simply plug the device’s 1/4”
phone jack into the left (mono) stereo input
and leave the right input bare. The signal will
be duplicated to the right due to the miracle
of jack normalizing.
19. 4-Band Equalizer
The stereo channels of the AM mixers
feature equalizer almost identical to those
on mono channels; however instead of a Mid
frequency control and sweep control there
are High-Mid and Low-Mid controls instead.
They provide a peaking style of boost and cut
to middle frequencies, where the frequencies
are set at 3 kHz and 800 Hz for the High- and
Low-Mids respectively.
20. AUX Controls
The AUX controls on stereo channels are the same as on mono
channels, however, since the AUX mixes are always mono, any
stereo signal will be mixed into a mono signal before being sent
to the corresponding AUX mix.
21. Balance Control
This rotary control alternates the degree or level of audio that the
left and right side of the main mix should receive. Adjusting the
balance control will attenuate the left or right audio signals of the
channel accordingly.
22. Mute and Routing Buttons
The Mute, Main, 1-2 and 3-4 buttons on stereo channels do not
differ in their operation to mono channels at all. However, it is
important to make sure that when the 1-2 and/or 3-4 buttons are
pushed that the Balance control is set to the middle, as this will
ensure the stereo signal remains a stereo signal.
23. Stereo Channels 21/22 and 23/24(AM2442FX)
Stereo Channels 29/30 and 31/32(AM3242FX)
The final 2 stereo channels on both AM mixers feature slightly
simplified controls. Here you will find two AUX sends (permanently
wired to be pre-fader, useful in monitoring), a level control and Solo
button. As there are no routing switches, the signal is permanently
sent to the Main mix (and appropriate AUX mixes).
