Bridging
Any or all pairs of channels (front, rear or sub) on your
POWERCLASS
™
multi channel amplifier are capable of being bridged into a 4 ohm mono
output without switches or bridging modules. 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.
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
