Figure 2-4 Setting console preamp gain
2. If there is insufficient gain to keep the level LEDs lit green when no one is talking,
set the rear panel LEVEL switch to -10.
The auto mix gain meters show the channel gains resulting from the process. They
are not level meters!
3. Adjust your console’s preamp gains so all LED meters float at about the same gain
when no one is talking.
Each talker now has equal access to the system gain. Note that this is not the same
as adjusting for each talker’s level.
4. Adjust the console faders to balance the talkers.
Don’t worry about the relative positions of the faders because the automixing al-
gorithm takes care of cueing the mics in and out.
5. If your Model E-1A is inserted to the console post-fader, you are good to go.
6. If the Model E-1A is inserted pre-fader, you must use the Model E-1A’s mute but-
tons to mute mics.
With pre-fader insert patching, pulling a fader down to mute a mic leaves that
mic’s signal in the automxing process. This can cause the room ambience in the
mix to fluctuate, or in the worst case, cut off a talker.
