POWER AMPLIFIER INPUTS
Parallel to the XLR-type inputs, output connectors are provided,
offering the opportunity to feed additional power amplifiers with the
same signal.
The inputs are electrically balanced with pin-assignment according to
the IEC 268 standard.
Pin-assignment of the XLR-type input connectors:
PIN 1: SHIELD
PIN 2: a, +
PIN 3: b, -
Input sensitivity is factory set to 0 dBu.
The power amplifier can be set internally to +6dBu input sensitivity or
to +26dBu gain.
INPUT ROUTING
PARALLEL MONAURAL
Setting the selector switch to the PARALLEL/MONO position puts the
channel A and channel B inputs in electrically direct parallel configu-
ration, leaving you still the possibility to control the channels' level
settings separately, using the output controls A and B.
DUAL STEREO
When the selector switch is set to its DUAL/STEREO position both
channels are amplified individually.
