Although providing XLR-type connectors, on some mixing consoles the outputs are

carried out as unbalanced connections. If such a console is employed in your set-up

together with a STANDARD PRECISION SERIES power amplifier, pins 1 and 3 have to be

bridged or the pin 3 of the connection cable has to be left unconnected.

Feeding unbalanced signal sources via pin 3 (b, –, cold) and pin 2 (a, +, hot) into the

power amplifier can result in unusual humming noise and HF-interference leading to

damaging the amplifier itself or the connected loudspeaker systems.

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.

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.
