The pin assignments of the 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).

Refer to the operating manuals of your balanced-output line-level source to verify that the pin assignments of its output connectors correspond to the CAP-2100. If this is not the case, wire the cables so that the appropriate output pin connects to the equivalent input pin.

To achieve the best possible results, we suggest that you use only high- quality interconnect cables. Please consult with your local Classé dealer for advice on the best cables for use in your system.

7IR Input and Output

Your Classé integrated amplifier includes two 1/8th-inch mono mini-jacksin order to support the infrared (IR) remote controls that are ubiquitous

today. Infrared commands exist (for example) for toggling the integrated amplifier between operate and standby, in addition to 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 integrated amplifier in the larger context of a complete system.

The list of commands available is quite extensive, enabling even complex macros (chains of commands strung together) to operate flawlessly. If this capability is of interest to you, we strongly recommend discussing it with your authorized Classé dealer.

Note that IR Input and Output is a bit of a misnomer: the input and output of these plugs is electrical in nature, not infrared. They are used with standard IR receivers, distribution amplifiers, and emitters (available from your dealer) to translate the remote’s IR signal to an electrical signal and vice versa. 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 integrated 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 integrated amplifier is designed to respond to IR commands of

5 VDC, with the tip of the mini-plug defined to be positive relative to the shank of the plug.
