Classe Audio CA-2200 owner manual 4Classé CAN Bus Control Ports, 5IR Input and Output

(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 and soldered 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.

These RJ-45connectors are reserved for future control and communication applications using Classé Audio’s implementation of the Controller Area Network (CAN) Bus specification.

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.

Since an IR distribution system such as your dealer may design for you usually must control many products, your amplifier includes both an IR input (for the control of this product) and an IR output (so as to pass along the same signal to the next product). This allows you to “daisy chain” your control wires from one product to the next.

The amplifier is designed to respond to IR commands of 5 Volts DC, with the tip of the mini mono-plugs defined to be “positive” relative to the shank of the plug.
