RCA connectors accept signals from unbalanced
sources, while the XLR connectors are for balanced
sources. A small toggle switch near the input
connectors selects either the balanced or unbalanced
inputs.
When you have a choice, a balanced connection
will offer slightly higher sound quality than an
unbalanced connection.
Note that the input selector switch for some
channels will be in the “up” position, while the
input selector switch for other channels will be in
the “down” position.
Only one set of inputs (balanced or
unbalanced) may be connected at a
time.
Pass-Through Outputs
The pass-through output
connector is wired in parallel
with the input connector.
Each channel features a pass-through output,
supplied via an XLR connector. This allows
multiple channels to be driven with a single source
and is especially useful for subwoofers, passive bi- or
tri-amplification, or distributed sound systems.
Simply use a balanced cable to connect the
pass-through output of one channel to the XLR
input of another channel on the same amplifier, or of
another amplifier with true balanced inputs.
The pass-through output does
not convert unbalanced sources
to a true balanced signal.
If you wish to drive an unbalanced amplifier from
the pass-through outputs, you will need to use
XLR-to-RCA adapters at the pass-through outputs.
These are available from your Ayre dealer.
