Ayre Acoustics V-6x - Manual (Page 6)

Inputs
When you have a choice, a
balanced connection will
usually offer slightly higher
sound quality.
The power amplifier can be driven by a
surround-sound processor or preamplifier. There are
two sets of input connectors for each installed
channel of the Ayre V-6x. The RCA connectors
accept signals from unbalanced sources, while the
XLR connectors are for balanced sources.
Only one set of inputs
(balanced or unbalanced) may
be connected at a time.
A small toggle switch near the input connectors
selects either the balanced or unbalanced inputs.
Note that the input selector switch for one channel
will be in the “up” position, while the other
channel’s input selector switch will be in the
“down” position.
Using the incorrect position on
the input selector switches will
not harm the equipment, and
the amplifier may even seem to
operate normally. However,
some sonic degradation occurs
in this situation.
Selecting “Unbal” connects the inverting input to
ground through an isolation resistor. Therefore, the
incorrect setting of this switch forces a balanced
source to operate in unbalanced mode. Conversely, if
the selector is set to “Bal” while using an
unbalanced source, the unused inverting input is
susceptible to hum pick up and radio-frequency
interference.
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
