8Classé 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.

9IR Input and Output

Your Classé preamplifier includes two 1/8th-inch mini mono-jacksin order to support the infrared (IR) remote controls that are ubiquitous today. Infrared commands exist (for example) for toggling the preamplifier 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 preamplifier 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 preamplifier 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 preamplifier is designed to respond to IR commands of 5 Volts DC, with the tip of the mini-plug defined to be positive relative to the shank of the plug.
