DISCRIMINATOR SENSITIVITY OF GATED INPUTS
Discriminator Sensitivity - The mixers are
shipped from the factory with the
discriminator sensitivity optimized for use with
4 - 8 microphones (normal sensitivity).
There are two other sensitivities provided with
each mixer. In applications where only two or
three microphones are connected to the mixer
the discriminator might need to be less sensi-
tive (low sensitivity). In applications in which
the microphones are mounted in the ceiling,
the discriminator might need to be more sen-
sitive (high sensitivity).
See figure below for jumper settings to
change sensitivity.
