4Classé CAN-Bus Control Ports

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.

6DC Trigger Input and Output

Many audio/video preamplifiers can supply a DC control voltage to associated equipment in order to induce desired behavior. Your Classé amplifier can take advantage of these capabilities in order to be switched between operate and standby automatically, perhaps in concert with the A/V preamp itself.

Two 1/8th-inch mini mono-jacksprovide this remote-controlled turn-on (that is, toggling between operate and standby) of the amplifier. These jacks provide a simple pass-through of the control voltage from one to the other, allowing you to “daisy-chain” a series of amplifiers quite easily.

The remote trigger will be operated by the presence of 5–12 Volts DC, with tip polarity as shown below:
