Harman Kardon CITATION 5.1, Owner'S Manual

Page: 16 / 24

For two-channel use, make certain that BOTH bridging switches are engaged by
switching them down, to the “bridged” position.
In the bridged mode, the connections to your speakers should be made using only
the top row of binding post connections. Follow the connection diagram that is
between the speaker connections. For the speaker connected to the Channel One
input, connect the “+” terminal of the Channel One output to the wire going
to the “+” or red colored connection on your speaker. Connect the “+” terminal
of the Channel Two output to the wire going to the “-” or black terminal of
your speaker.
Repeat this procedure so that the input signal connected to the Channel Three
input connector is connected to your speaker using the “+” speaker output con-
nector of Channel Three as the “+” or “red” wire, and the “+” speaker output
connector of Channel Four as the “-” or “black” wire.
To complete the bridging of the circuits, use the jumpers packed with the 5.1 to
make a connection between the Negative (“-”) speaker connection terminals for
Channel 1 / Channel 2, and Channel 3 / Channel 4 as shown in Figure 2C.
WARNING:
The jumper connections should not be made when the amplifier
is turned on. This connection must be made before operating the amplifier in
a bridged mode.
Note: When using the 5.1 in a dual-bridged configuration, particularly with
4 ohm speaker loads, it will probably be necessary to provide additional cooling
using a small fan. This cooling will also be needed in the dual-bridged mode if
the amplifier is enclosed in a cabinet. Consult your dealer or custom installer for
more information.
