INSTALLATION STEP 1
COHERENT STEREO™ /
MIXED-MONO / BRIDGED MONO
The REFERENCE amplifiers have the ability to operate in any one of the
following modes:
Coherent Stereo™ with identical left and right stereo channels for
maximum fidelity. Best choice for satellite speakers. Use this mode unless
Mixed-Mono is necessary.
Mixed-Mono in order to drive stereo and mono simultaneously; works well
for center channels. It can be used anytime you need a summed mono
channel. Somewhat sacrifices sonic accuracy as additional circuitry is
introduced to one channel. In Mixed-Mono, the left channel is inverted, see
diagram below or on the bottom of the amplifier.
Bridged Mono for dedicated single channel operation; ideal for driving
subwoofers. It is also used when large amounts of power are necessary for
single speakers. In bridged mono, only the right channel input is active.
In bridged mono, only the right channel input is active.
NOTE: If you intend to drive a
REFERENCE amp in Mono but have stereo
outputs from your crossover or source unit,
you can put the switch in Mixed-Mono but
follow the normal wiring for Bridged Mono.
