CONNECTING THE AUXILIARY OUTPUTS TO A
COMPONENT WITH UNBALANCED INPUTS
The 865 Integrated Amplifier’s balanced outputs can drive
unbalanced inputs with a cable having an XLR connector at the source
(865) end and an RCA connector at the load end.
A special cable required to make this connection connects Pin 1
to the shield and Pin 2 to the RCA center conductor. It leaves Pin 3
unconnected.
Connecting the unused Pin 3 to ground will cause excessive ground
currents and degrade performance. Use an ohmmeter or continuity
checker to determine how a cable is wired. The diagram of the proper
termination technique for this cable is shown below.
When using these outputs for bi-amplification into unbalanced
inputs and if the external amplifier has the standard 26dB of gain, the
loudspeaker outputs of the 865 will be 6dB louder than the external
amplifier.
