Output balance options
outputs are impedance balanced as standard
operating at nominal -2dBu and with +21dBu
maximum drive. They provide similar interference
rejection to electronically balanced outputs when
connected to balanced equipment inputs.
electronically balanced option is available if you
require nominal +4dBu and higher output drive up to
+26dBu over very long cable runs. However, it is not
usually necessary to fit this option as the impedance
balanced drive satisfies most applications.
that you really need the option before fitting it.
There are two balanced driver ICs which may be
used. Either is suitable. These are available from
Allen & Heath or most electronic component
suppliers. The Allen & Heath part number is shown
below:

For each aux master, snip the legs of the two zero
ohm resistor links next to the IC socket.
removes them from the circuit. Now simply plug the
option IC into the socket. Observe the correct IC
pin1 orientation and make sure its legs are correctly
aligned with the socket. Test the output once the
work is complete. You should measure the same
level but opposite polarity signal between + (hot) and
ground, and – (cold) and ground.
Sys-Link II input/output option

replaced with an optional card which provides the
console inputs, outputs and PFL system on two
37way D connectors for linking to other Allen &
Heath consoles already fitted with Sys-Link II. The
3
WZ 14:4:2 can become an input channel expander
(slave) or have its number of input channels
expanded (master) when linked to other consoles.
A 37way shielded multi-core cable carries the
MixWizard balanced mix signals and PFL system to
or from the other console.
IMPORTANT: Note that you need an adapter cable
if you are connecting Sys-Link II (Version 2) to the
older Sys-Link I (Version 1) standard.
