Home Theater Example (Diagram 8)
This example uses the power amplifier to drive the speakers in the home the-
ater system. The two channels remaining are used to provide music to a sepa-
rate area or room.
This configuration utilizes the bridging mode to provide additional power.
The following adjacent channels are bridged together: 1and 2, 3 and 4, 5
and 6 , 7 and 8, 9 and 10. Note that on each one of these the signal is con-
nected to the “LINE IN” on the first channel of the pair, the Bridging switch is
set to “ON”, and the Impedance switch is set to 8 ohms. In addition, the
speaker outputs used are the ones to the left and right of the Bridged text on
the output.

There are many ways to configure the BB1235 amplifier. The following pages
contain some typical installation examples. Use these examples to generate
ideas for your system design.
Multi-Room Installation Example (Diagram 4)
This illustrates the simplest use of the BB1235, distributing audio throughout
the home. In this example only one source can be selected at a time, all pairs
of speakers have the same audio signal available.
The Input Selection switch is set to “BUS” on all channels. Adjacent channels
are assigned left and right.
Multi-Zone Example #1 (Diagram 5)
This illustrates the simplest way to provide an audio signal to one area that is
independent of the main audio signal. Zone 2 uses a CD player connected to
just that Zone. The rest of the system operates Zone 1 and is connected to
the preamplifier / receiver.
The Input Selection switch on channels 1-10 is set to “BUS” with adjacent
channels assigned left and right. The Input Selection Switch on channels 11
and 12 are set to “LINE”.
Multi-Zone Example #2 (Diagram 6)
This illustrates the ability to listen to different audio signals in each zone, inde-
pendent of every other zone. The system relies on a multi-zone preamplifier
or up to 6 independent preamplifiers.
The Input Selection switch on each channel is set to “LINE”
Home Theater / Multi-Room Example (Diagram 7)
This configuration allows the user to access the sources connected to a home
theater receiver for use in a multi-room installation. It relies on the home the-
ater receiver having a multi-room or similar output.
The Input Selection switch on each channel is set to “BUS” with adjacent
channels assigned left and right.
