3.4. Input connections

The signal input connections (34, 35, 36, 37, 38, 39) are electronically balanced XLR-3 sockets,

with input impedance higher than 20k and a nominal sensitivity of 0dBV(1V). Pin assignment:

1. GROUND

2. PHASE (in phase with the output)

3. NON PHASE (inverted phase)

The following diagram shows the connection of balanced and non-balanced audio sources:

The “STACK” (20, 21) are in parallel with the inputs and are used to supply the same "INPUT 1,

INPUT 2" input signal to other amplifiers or sound systems. This signal output connectors are of jack 1/4"

type. The pin assignment is as follows:

HOT or direct signal > Tip

COLD or inverted signal > Ring

GROUND > Body

Some of the connection options and the corresponding switch settings are described later in

paragraph 3.5.

Depending on the chosen option, the "SP" indicators will only light for the active channels.
