14.3 Mic Input
Each microphone input unit features two inputs and A/B switchover. In-
puts A and B are transformer-balanced mono microphone inputs. The
maximum input level is such that also mono line level signals can be proc-
essed if required.
The analog path has an insert point right after the preamplifier stage. Both
the insert send and return signals are electronically balanced. The nominal
send and return levels are +6 dBu, with 9 dB headroom for 0 dB

Two control outputs (CTRL OUT xA/B) are available for each individual

players, R-DAT units, or a radio automation system, or for red light sig-
naling. The control signals can be triggered by various functions and de-
pend on the selected fader start mode (INPUT CONFIG. page). For details
please refer to

open.
PFL/ON & FADER Output is closed if either PFL is active (independent of the fader position),
or ON key is pressed and fader is open.
