BRIDGING
B r i d g i n g
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
