Expansion port input signal gain control (see figure 53 on page 97,
E
)
AM block — The automixer block, when inserted, manages multiple input sources,
gating or varying input gain automatically, to improve the performance when multiple
inputs are in use. The automixer block is identical to as described for the Mic/line Inputs
AM block on page 108.
Gain control — The always-present expansion port input pre-mixer gain control
provides a fader with a gain range of 12 dB to -100 dB, adjustable in 0.1 dB
increments. The Gain block is identical to as described for the Mic/line inputs signals Gain
block on page 101.
Post-matrix signal processor chain (see figure 53,
F
)
The post-matrix signal processor chain makes adjustments to program audio material, after
it is tied to a specific output but before it is mixed with microphone or other audio material.
Filter block — The filter processor block, when first inserted, provides
one of ten filter selections; additional filters can be then be added. The
available filters and the process for adding additional filters are as

provides left and right channel controls to adjust the audio level of each
audio output from the AV switcher block through a range of -100 dB to +12
dB to ensure that there is no noticeable volume difference among sources.
Click and drag the desired fader (
1
) or click in the dB field (
2
) and enter a
value.
3
Mute buttons — Click to separately silence and unmute
unmute the left and right audio channels. If you mute both
channels, audio is completely silent on that output. When one
or both channels are muted, one or two red indicators in the block turn
on.
NOTE: When the left and right channels are ganged, either Mute
button mutes and unmutes both channels.
4
Gang button — Click to tie the left and right fader controls together.
Ganged faders move together at relative levels to the top or bottom of their
travel. If one fader reaches the limit of its travel first, it retains that position
while the other fader continues to travel. When the ganged faders travel in the reverse
direction, the fader that was at its limit reverts to its position relative to the other fader.
NOTES:
• The indicator (
5
) means that this fader is part of a group master (group 1 in
this example) (see Group masters on page 119 to create group masters).
• Multiple masters can be created for a fader, in which case the
5
indicator is .
• By default, the front panel Volume knob controls this fader.
