Connecng a power amplier/speakers
Bi-amping
The pre-amplier output may be used in conjuncon with
addional power amplier(s) to signicantly upgrade your
loudspeaker system through Bi-amping.
The Cyrus range of power ampliers is recommended for
this applicaon as they will have the correct matching
gain. Both stereo and high power monobloc Cyrus power
ampliers are available to partner your Classic PRE.
NOTE: A bi-amp system can only be set up with speakers
that have bi-wire connecons (separate bass and treble
connecons).
CAUTION: Ensure that any bi-wire or bridging links are
removed from the speaker terminals before connecng up
a bi-amped system.
Refer to the wiring plan of a bi-amplied system below.
Take care to connect each of the output channels to the
correct power amplier and loudspeaker.
Connecng speakers
The speakers will connect to the power ampliers. Refer to
the power amplier handbook for instrucons to connect
the speakers.
