Unbalanced connection
•
Connect a phono interconnect from the ‘PRE OUT’
sockets to the unbalanced inputs of the power
amplifier.
Ensure left and right channels are correctly connected.
Connecting speakers
The speakers will connect to the power amplifiers. Refer to
the power amplifier handbook for instructions to connect
the speakers.
Connecting a power amplifier/speakers
The Pre-XR requires an external power amplifier to
drive the system loudspeakers. Two types of connection
are provided for power amplifiers - balanced via XLR
connectors and unbalanced via phono connectors. Either
or both connections can be used.
If your power amplifier has balanced inputs, these are
preferred for the best quality.
Balanced connection
Balanced connection is shown in the example diagram
below with dual mono power amplifiers and bi-wired
speaker connection.
•
Connect a balanced XLR interconnect from the
‘BALANCED PRE OUT’ sockets to the balanced inputs of
the power amplifier.
Ensure left and right channels are correctly connected.
