BRIDGED OPERATION IS 8 OHMS. DO NOT OPERATE A
ZONE IN THE BRIDGED MODE INTO A SPEAKER THAT IS
LESS THAN 8 OHMS NOMINAL IMPEDANCE.
Bridging channels is accomplished using the

Source Connections DSP 2-150
On the left side of the rear panel are the audio inputs for the left
and right channels. In addition to the left and right inputs there are
also loop outputs for each channel.
The loop outputs allow multiple amplifiers to share common audio
sources. The loop outputs on the amplifiers are not buffered.
The number of amplifiers that can be connected in series will
depend on the output level of your audio source. The source
connected to the LEFT and RIGHT LINE IN Inputs pass through the
LEFT and RIGHT LINE Outputs (see Figure 12).
