Cloud Z8II User Manual

Z4II & Z8II Installation and User Manual v1.0 1111
manuals with each item for guidance on how the outputs
should be connected to an unbalanced input.
However, the wiring methods shown in g.11 and g.12 will
work in a large number of cases. If hum or other distortion
is found to result, try disconnecting the ‘cold’ leg of the
balanced output (pin 3 on XLRs).

Zone outputs
Connect the inputs of the power ampliers feeding the
loudspeakers for each zone to ZONE 1 to 8*. Note that
the zone outputs are all mono. All outputs are balanced and
will drive input impedances down to 600 Ω. 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 in g.13.
Note that the screen can be left unconnected at the source
end if earth loops are a problem.
*ZONE 1 to 4 only on Z4II.

Unbalanced inputs
