If you are using your Classé power amplier with a Classé preamplier/
processor, you’re all set – just remove the supplied shorting pins (between
Pins 1 and 3) from the amplier’s XLR connector(s), take standard
balanced interconnect cables and plug them in.
If you are using another brand of preamplier or processor, please refer to its
operating manual to verify that the pin assignments of its output connectors
correspond to those of your amplier. If not, have your dealer obtain cables
with the appropriate output pin connecting to the equivalent input pin.
2 Single-Ended (RCA) Input
Single-ended cables using RCA connectors are the most common form
of analog connection used in consumer electronics. When implemented
carefully and with use of high quality interconnecting cables, this standard
can provide excellent performance. Classé has gone to extraordinary eort
to ensure that the single-ended (RCA) inputs of your power amplier
perform exceptionally well.
When using single-ended (RCA) inputs: to reduce the potential
to conduct noise, be sure to leave the shorting pins in place
between pins 1 and 3 of the XLR connector.
3 Speaker Outputs
e Delta MONO is designed to accommodate the impedance range of all
commercially available loudspeakers. Your dealer is in a good position to
advise which and/or how many ampliers are suitable for your particular
loudspeakers.
To facilitate bi-wiring, two pairs of high-quality ve-way binding posts
are provided on the amplier. ese connectors are made of rhodium-
plated copper and designed with a feature called Torque-Guard, which
ensures the optimum contact pressure to mate with your speaker wire
connector lugs without allowing the connector to be over-tightened. As
you tighten them, they will reach the proper torque and therefore act like
a torque wrench with click sounds indicating that the proper torque has
been reached.
In practice, bi-wiring involves connecting two (preferably identical) sets
of speaker cables between each amplier channel and its corresponding
loudspeaker. In many cases, the benet is a subjectively improved level of
clarity and detail from the speaker, as a result 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 oer 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 frequencies.)
Although the binding posts on your Classé amplier will accept bare wire
connections, we strongly recommend the use of high quality spade or hook
lugs, crimped 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-circuits from poorly-terminated connections.
