an excellent job of rejecting noise and interference that might otherwise be
picked up between the components, due to either EMI (electromagnetic
interference) or RFI (radio frequency interference). In the world of wireless
telecommunications, there is more potential interference around than ever
before—it makes sense to keep it out of music and movie soundtracks.
For this reason, we strongly recommend using the balanced analog
interconnections between your Classé components wherever possible.
e pin assignments of these XLR input connectors are:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
ese pin assignments are consistent with the standard adopted by the
Audio Engineering Society (AES14-1992).
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) input of your power amplier is
as good as possible. However, this connection standard cannot oer the
immunity from interference that balanced interconnection does—hence
our recommendation to use the balanced inputs when possible.
3 Speaker Outputs
Twopairsofhighqualityve-way binding posts are provided on the
amplier, in order to facilitate bi-wiring.
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.
