Bridging
Any or all pairs of channels (1/2, 3/4 or 5/6) on your
POWERCLASS
™
multi channel amplifier are capable of being
bridged into a 4 ohm mono output without switches or bridging
modules (2 ohm mono on Channels 5/6). This feature permits
the creation of a mono channel for a subwoofer or center
channel.
Deriving the mono channel is accomplished by using the left
channel positive wire of the pair as the positive speaker wire
and the right channel negative wire as the negative speaker
wire. You should always be working with the wires of a single
POWERLOCK
speaker connector when bridging a pair of
channels.
NOTE: It is important that a minimum 4 ohm impedance is
observed (2 ohm mono on Channels 5/6). If the impedance
drops significantly below 4 ohms while the amplifier is wired
in the bridged configuration, the amplifier's protection
circuitry may engage.
Mixed Mono Output
The ability to run stereo speakers while simultaneously running
a mono output from the same channel pair is accomplished by
running the stereo speakers normally and tapping into the
appropriate wires for the "mixed mono" channel (left channel
positive for the positive speaker wire and right channel negative
for the negative speaker wire). Total speaker impedance should
be no lower than 2 ohms on the stereo channels and 4 ohms
on the mono channel.
NOTE: Passive crossovers must be used for "mixed mono"
operation. Choose a low pass crossover around 100Hz for
your subwoofer, then choose a high pass crossover for your
stereo channels. The high pass crossover must be at the same
or slightly higher frequency than the low pass crossover to
maintain the correct impedance. See your
PrecisionPower
dealer or call

for more information about
passive crossovers.
