11DC Trigger Input and Output

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

The 1/8th-inch mini mono-jack Trigger In provides for remote-controlled turn-on (that is, toggling between operate and standby) of the preamplifier.

Two 1/8th-inch mini mono-jacks provide individually controllable DC trigger outputs which can be used for any of a number of purposes, as described in The Menu System. For example, your dealer can program Trigger Out1 to toggle your Classé power amplifier between operate and standby with your CP-500.

The remote trigger input will respond to the presence of 5–12VDC, with tip polarity as shown below:

Similarly, the trigger outputs will create a 12VDC signal that can source up to 100mA of current.

12AC Mains Power Switch

The main power switch for the CP-500 is located near the middle of the rear panel, just above receptacle for the power cord.

Switching the unit on puts it in standby mode. The preamplifier should be in standby before being switched off.

Potentially dangerous voltages and current capabilities exist within your preamplifier, even when disconnected from AC mains. Do not attempt to open any portion of the preamplifier’s cabinet. There are no user-serviceable parts inside your preamplifier. All service of this product must be referred to a qualified authorized Classé dealer or distributor.

13AC Mains Input

An IEC standard power cord (supplied) is used with the CP-500. Plug the cord into the IEC receptacle provided, and the other end into a suitable wall outlet.
