Amplifier Connections: unbalanced RCA
If your amplifier has RCA inputs, you can
connect them to the preamplifier’s Main 1 or
Main 2 outputs. It does not matter which pair
you use, because they are identical.
Main 2 is provided if you want to run a
second amplifier, perhaps to play speakers in
another room, or to drive an active subwoofer.
A third amplifier can be connected to the
balanced XLR outputs if you have another set
of speakers in a third room. Note that all the
amplifiers would be playing the same music
selection.
System Configurations
If you are using an electronic crossover to
bi-amp or tri-amp your speakers:
• Connect a cable from either of the
preamplifier’s main outputs to the
active crossover’s inputs
• Connect the crossover’s High, Mid,
and Low outputs, as appropriate, to the
separate power amplifiers in your
system.
