Bridging Channels
Under typical conditions, for surround-sound or home theatre applications, there
are two channels available for the front loudspeakers, a channel for the center
loudspeaker, a pair of channels for the rear effects, and an extra channel to drive
either a subwoofer or a second center channel loudspeaker.
The Perreaux 6160 multi-channel amplifier can be thought of as three stereo
amplifiers built into a single box. Each pair of channels within the unit can be
bridged to form a single channel with approximately three times the potential
output of a single channel. This facility allows this 6160 to be used in a number
of configurations. For example, bridging two of the 6160 pairs of amplifiers
will provide two channels of approximately 425W into 8
Ω , suitable for the main
loudspeakers of the system, and two channels of 160W into 8 Ω for a remote set
of loudspeakers.
Ultimately, two 6160 units both operating with all channels bridged, will offer
six channels of high power amplification (6 x 425W into 8
Ω ) for home theatre
applications.
To configure for bridged mode:
à Ensure the power switch on the 6160 is switched to the OFF position
and disconnect unit from mains supply. Allow a minute to discharge
stored potential.
à Select the pair of channels to be bridged. For this example, we will use
channels 5&6. (Other pairs 1&2 and 3&4 are bridged similarly.)
à Disconnect ALL input and output cables (interconnect cables and
loudspeaker cables) from channels 5&6.
à Set the Bridging Switch to the bridged position. This converts internal
circuitry from normal to bridged mode.
à Connect the loudspeaker cable across the POSITIVE terminals of
channels 5&6 loudspeaker output terminals. When bridging two
channels, the positive loudspeaker terminals of the bridged pair form
the loudspeaker terminals for the bridged channel, i.e. the positive
output terminal of the odd numbered channel becomes the POSITIVE
terminal of the bridged pair; the positive terminal of the even numbered
channel becomes the NEGATIVE terminal of the bridged pair. To
explain further, connect the positive conductor to the positive terminal
of channel 5 and the negative conductor to the positive terminal of
channel 6, i.e. the two red terminals. DO NOT connect any cables to
the black terminals; channel 5 negative terminal (-) and channel 6
negative terminal (-).
