Balanced sources:
Source equipment with balanced outputs may be connected
directly to Line Inputs 3, 4 5 or 6. Use good quality twin-
and-screen cable and connect to the mating screw-terminal
connectors provided as shown below:
PIN CONNECTION
1 Screen
2 Signal ‘-’ (cold)
3 Signal ‘+’ (hot)
If it is necessary to connect an item of source equipment with
an unbalanced output to Line Inputs 3 to 6, connect the signal
to Pin 3 (“hot”) and Pin 1 (screen), as shown below:

Mono and stereo sources:
The Z8MK4 and Z4MK4 are mono mixers; the stereo line
inputs are summed internally to mono. Stereo sources should
be connected in a normal stereo conguration, using both L
and R inputs. If connecting a mono source with only a single
output, it may be connected to either the left or the right
input.
Zone outputs
Connect the inputs of the power ampliers feeding the
loudspeakers for each zone to the OUTPUT connectors
for Zones 1 to 8*. Note that the zone outputs are all mono.
The outputs are balanced and will drive input impedances
down to 600 ohms. Nominal output level is 0 dBu (775 mV).
The output is designed to drive professional/industrial power
ampliers with balanced inputs (typically on XLRs). In this
case, wire as the diagram below. Note that the screen can
be left unconnected at the source end if earth loops are a
problem.
