Classe Audio CA-D200 Single-Ended RCA Input, Speaker Outputs, Classé CAN-Bus Control Ports

2Single-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 effort to ensure that the single-ended (RCA) input of your power amplifier is as good as possible. However, this connection standard cannot offer the immunity from interference that balanced interconnection does—hence our recommendation to use the balanced inputs when possible.

3Speaker 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 identical) sets of speaker cables between each amplifier channel and its corresponding loudspeaker. In many cases, the benefit 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 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 frequencies.)

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.

Actually, this IR Input and Output description is a bit of a misnomer: the input supplied to these plugs is electrical in nature, not IR. It is obtained by using standard IR receivers, distribution amplifiers, and emitters (available from your dealer) to translate the remote’s flashes of infrared light into corresponding pulses of electricity. 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.
