Applications
Mono Bridge Operation
The two internal power amplifiers (CHA and CHB or CHC and CHD) can be bridged together to
form a single, higher powered amp.
This is especially useful when using the amplifier to power a subwoofer. In the mono mode, the
amplifier uses the channel A or C input jacks and sensitivity control(channel B and D's are
disabled). When operation in this mode, each channel is independently protected. The minimum
speaker load impedance must be 8 ohms.
Please set the amplifier as follow: Link CHA and CHB ,or CHC and CHD, Set the phase of the CHB
or CHD to 180°
