System configurations
1. Bridged mono operation
In a conventional system the speakers are
connected to an integrated amplifier or a
combination pre-amp and power amplifier.
Stereo output stages have separate inputs
and out-puts for the left-hand and right-
hand channels.
Certain very high-quality power amps can
be switched from stereo to bridged mono
operation. Some are even designed
exclusively as mono amplifiers.
Two of these power amps are required to
drive a pair of loudspeakers. One output
stage is connected to the pre-amplifier's
left-hand channel, and thus receives a
mono signal. The pre-amplifier's right-hand
output channel must be connected to a
second power amp of the same type.
In this mode of operation the output power
of the amplifier is more than doubled.
2. Bi-Wiring
The term Bi-Wiring describes an alter-
native method of connecting loudspeakers
in which the signals for the bass and mid- /
high-frequency
ranges
pass
along
separate speaker cables.
This gives the user the opportunity to use
the optimum cable for each part of the
frequency spectrum.
The pre-requisite for a Bi-Wiring system is
that the speakers should feature a bi-
wiring terminal.
Caution:
It is essential to remove the link pieces at
the Bi-Wiring terminals if you want to use
this system of wiring.
