The 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

These pin assignments are consistent with the standard adopted by the Audio Engineering Society (AES14-1992).

If you are using your Classé power amplifier with a Classé preamplifier/ processor, you’re all set – just remove the supplied shorting pins (between Pins 1 and 3) from the amplifier’s XLR connector(s), take standard balanced interconnect cables and plug them in.

If you are using another brand of preamplifier or processor, please refer to its operating manual to verify that the pin assignments of its output connectors correspond to those of your amplifier. If not, have your dealer obtain cables with the appropriate output pin connecting to the equivalent input pin.

2Single-Ended (RCA) Input

All five 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 effort to ensure that the single-ended (RCA) inputs of your power amplifier perform exceptionally well.

3Speaker Outputs

One pair of high-quality five-way binding posts are provided for each amplifier channel. They are positioned in such a way as to allow the best access for fitting high-quality speaker cables.

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 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.

4Classé CAN-Bus Control Ports

These RJ-45connectors are reserved for control and communication applications using a Classé implementation of the Controller Area

Network (CAN) Bus specification. Refer to the CAN-Bussection located later in this manual for more information.

5IR Input and Output

Your Classé amplifier includes two 1/8th-inch mini mono-jacksin order to support the IR remote controls that are ubiquitous today. IR commands 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 remote control systems, facilitating the control of the amplifier in the larger context of a complete system.
