1. Put all the live mic channels in automatic mixing mode by deactivating bypass

and mute.

2. Activate the mute buttons for all unused channels.

3. Using a normal speaking voice, adjust the console input trim controls to the highest

possible gain without clipping.

The input gain to the Model E should be high enough keep the level LED lit

green during silences. If the input trim controls do not provide enough level,

set the +4/-10 switch to the -10 position.

If the preamp gain controls are set too low, the inputs drop below their minimum

operating level. This causes downward expansion to prevent feedback but the

smooth ambience is disrupted.

4. Set the console faders to your normal operating positions.

5. Balance the preamp gain controls so the fluctuating ambient noise registers

equally on the Model E’s meters.

Note that raising the preamp gain of one channel causes its gain to rise and the

others to fall; it’s a balancing act. When balanced, all mics have equal access

to the system gain.

6. If clipping occurs because someone speaks louder than expected, turn down all

of the console’s input trim controls the same amount, which maintains the am-

bient noise balance.
