Please Note.
The ISO Balancer is normally supplied with the Left and Right
Output Pin 1 floating to ensure full transformer isolation, with the two in-
ternal Pin 1 jumpers (designated G1 and G2) set in the 'Lift' position.
When it is being used in conjuction with the ISO De-Balancer we suggest
that these two internal jumpers be moved to the 'In' position. This ensures
that the interconnecting cables' shield drains back through the ISO Balancer
Ground circuit.
Full transformer isolation is still supplied by the ISO De-Balancer's Input

Using your Audibox
The ISO Balancer is designed to con-
vert an Unbalanced signal to a Bal-
anced signal suitable for connection
to professional audio systems. It is a
self contained, stand alone dual
channel unit with an ultra low noise
audio transformer inside. It will have
applications in Live Sound, Studio or
Broadcast use.
The ISO De-Balancer does the op-
posite, and converts a Balanced sig-
nal to an Unbalanced signal suitable
for connecting to consumer prod-
ucts. It is a self contained, stand alone
dual channel unit with an ultra low
noise audio transformer inside. It will
primarily have applications for Instal-
lation Sound, although Studio or
Broadcast engineers will find it a use-
ful tool as well.
Power Requirements
None. The ISO Balancer and ISO
De-Balancer are passive iso-trans-
former coupled devices,
ie.
they
don't need power to run.
Please note that it is advisable to
power down the system before con-
necting these units, to avoid the risk
of sending large electrical and signal
noises through the system when dis-
connecting and connecting.
