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

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
All ve channels support single-ended inputs for use with the widest range
of preamp/processors.
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.
3 Speaker Outputs
One pair of high-quality ve-way binding posts are provided for each
amplier channel. ey are positioned in such a way as to allow the best
access for tting high-quality speaker cables.
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.
4 Classé CAN-Bus Control Ports
ese RJ-45 connectors are reserved for control and communication
applications using a Classé implementation of the Controller Area
Network(CAN)Busspecication.RefertotheCAN-Bus section located
later in this manual for more information.
5 IR Input and Output
Your Classé amplier includes two 1/8th-inch mini mono-jacks in order to
support the IR remote controls that are ubiquitous today. IR commands
exist for toggling the amplier between operate and standby, as well as
discrete command codes for either operate or standby. ese codes may be
used in “macros” for sophisticated remote control systems, facilitating the
control of the amplier in the larger context of a complete system.
