Two Stereo Line Inputs
The analog outputs of consoles, worksta-
tions, off-air receivers, or virtually any
analog source can be connected to the
Model 40’s line inputs. The inputs accept
balanced or unbalanced signals, with an
acceptable input level range of –10dBV to
+10dBu. Signal Present LEDs provide
assistance when adjusting the input level
controls.
Talent Amplifier Output Groups
Each of the two output groups is designed
to feed up to four StudioComm talent
amplifier modules. The physical output
of each group is a 3-pin male XLR-type
connector that provides power and left
and right audio to the talent amplifiers.
The talent amplifier output groups are
short circuit protected. Error conditions
are displayed by the Over Current LEDs
on the Model 40’s front panel.
