AUDIO CONNECTIONS
Analogue inputs
The analogue audio inputs use 3-pin 3.81 mm-pitch screw
terminal connectors. Mating connectors are supplied with
the unit. The inputs should be wired according to the
diagram below:
Hot (+):
Red (UK) or
Blue (US)
fig.2: Analogue Inputs
To minimise hum and noise pickup, balanced analogue
interconnections between audio sources and the
IndustryAmp should always be used wherever possible. If
driving from an unbalanced source, use the same wiring
as shown above at the amplifier end, but connect the 'hot'
core to the signal output and the 'cold' core to the ground
terminal of that output; the cable's own screen should be
connected at the amplifier end only.

Amplifier outputs
The amplifier outputs are on 3-pin 7.62 mm-pitch
screw terminal connectors. The secondary winding of
each channel's 100 V-line output transformer has an
intermediate tapping for use with 70 V-line systems, and
this is available at the same connector. Wire the output
connectors as shown below:
