Lowering
the
weight
control for one channel:
•
decreases the
auto mix gain
display during ambience for that channel and in-
creases it slightly for the others;
•
makes it more difficult for that channel’s talker to be heard over the others.
For optimal performance, balance the
weight
controls so the channel gains display
approximately equally when no one is talking.
Figure 5-10 shows eight- and four-mic systems with appropriate
auto mix gain
displays
when no one is talking.
Figure 5-10
Multiple mic ambience:
auto mix gain
hovers around -9 dB for eight mics, -6 dB for four mics
You can perform the following functions using the
weight
controls:
•
If there is ongoing noise near one mic (e.g., computer fan or air vent), sup-
press it by reducing that channel’s
weight.
Of course, you will hear that noise
increase when that talker speaks.
•
To allow the chairperson to override interruptions, set his/her
weight
higher
than the other channels. If you set the chairperson’s weight too high, quiet
speech from the other channels may be lost.
•
To duck all mics when another sound source is playing, use a
dummy input
,
that does not get routed to a mix bus.
