3.3.3 Setting up the Speech System
1. Put all the live mic channels in
auto
mode.
2. Activate the
mute
buttons for all unused channels.
3. For all unused channels, press the
preset
button until
mute
mode is selected.
4. De-activate the
music system
button.
This puts the channel in the Speech System.
5. Set all the
auto mix weight
controls to 0.
6. Adjust the console input trim controls to the highest possible gain without clipping,
assuming a normal speaking volume.
There should be enough gain for the
level
LED to remain green during silences.
7. Set the console faders to your normal operating positions.
8. Balance the
auto mix weight
controls so the ambient noise registers approxi-
mately equally on the
auto mix gain
displays.
Flickering is normal in the ambient noise condition, but try to get the channels
to average about the same gain on the displays. Note that raising the
auto mix
weight
of one channel causes its gain to rise and the others to fall. It’s a bal-
ancing act. Now all your mics are set for equal access to the system gain.
9. When the event begins, you may discover that some mics must be set to lower
gain to accommodate louder voices. Turn down the console’s input trim controls
to avoid clipping, then when no one is talking, turn up the
auto mix weight
of
that channel to re-balance the
auto mix gain
displays.
NOTE: If the
auto mix weight controls are turned down too far, the inputs drop below
the minimum computing level, the gains expand downward, and the green
level LED is not lit. THIS IS NOT DESIRABLE! If you want gating, use the
Music System.
