3 Speaker Outputs
Two pairs of high quality five-way binding posts are provided on
the amplifier, in order to facilitate "bi-wiring."
In practice, bi-wiring involves connecting two (preferably identi-
cal) sets of speaker cables between each amplifier channel and its
corresponding loudspeaker. In many cases, the benefit is a subjec-
tively improved level of clarity and detail from the speaker, as a re-
sult of being able to feed the two separate sections of its crossover
and driver complement with identical, yet separate signals.
(Many high quality loudspeakers also offer two sets of connections on their
speakers. Generally, one set of the connections on the loudspeaker feeds the
portion of the speaker's crossover network that supplies the woofer with its
signal; the other set of connections connects to the portion of the crossover
that supplies the rest of the speaker with the midrange and high frequen-
cies.)
Although the binding posts on your Classé amplifier will accept
bare wire connections, we strongly recommend the use of high
quality spade or hook lugs, crimped and soldered onto the ends of
your speaker wires. Using high quality connectors will ensure that
your speaker connections do not gradually deteriorate from fraying
and oxidizing bare wires. It also helps prevent accidental short-cir-
cuits from poorly-terminated connections.

These RJ-45 connectors are reserved for future control and com-
munication applications.
5 IR Input and Output
Your Classé amplifier includes two
support the IR remote controls that are ubiquitous today. IR com-
mands exist for toggling the amplifier between Operate and
Standby, as well as discrete command codes for either Operate or
Standby. These codes may be used in "macros" for sophisticated re-
mote control systems, facilitating the control of the amplifier in the
larger context of a complete system.
Actually, this "IR Input and Output" description is a bit of a mis-
nomer: the input supplied to these plugs is electrical in nature, not
IR. It is obtained by using standard IR receivers, distribution am-
plifiers, and emitters (available from your dealer) to translate the
remote's flashes of infrared light into corresponding pulses of elec-
tricity. The big advantages here include being able to easily route
the signals anywhere they might need to go, and the reliability of a
solid electrical connection.
