Bridged Mode
A pair of amplifier channels may be bridged together to make a single
output with a power rating equal to the sum of both channel power ratings
at twice the load rating of a single channel. In other words‚ bridging two
amplifiers rated for 160 Watts into 4 Ohms will produce 320 Watts into 8
Ohms.
In Bridged Mode‚ the channels operate at opposite polarity from each other
so that one channel pushes and the other pulls equally. This mode sends the
input signal to one channel and the same signal with its polarity reversed to
the other channel for any two channels (1/2, 3/4 on the CM 2204-AB/DV or
1/3, 2/5, 4/6, 7/8 on the CM 2208-AB/DV). For example, to bridge channels
1 and 2, connect the input signal to the channel 1 input connector using
the standard connections (see # 9, Channel Inputs in Back Panel section).
On channel 2 however, reverse the positive and negative input connections
so that the positive (+) connector is connected channel 2’s negative (-)
receptacle and the negative input connector (-) is connected to channel 2’s
positive (+) receptacle.
Both channel level controls (in this example‚ 1 & 2) MUST be used to
control the signal level and both MUST be set at the same position.
