Danger!

10DC 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-700.

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.

11Ground terminal

The ground terminal on your preamplifier is most often used for the ground wire of a turntable, assuming you have the optional phono module installed (see your authorized Classé dealer for more information on this option if you are interested). Connecting the ground wire from your turntable’s tonearm to this screw terminal usually minimizes any hum

or buzzing to which the turntable might otherwise be susceptible. Your authorized Classé dealer can assist you in handling this problem if it should arise.

12DC Power Input

The DC Power Input for the CP-700 is located near the middle of the rear panel. Connect the provided multi-pin “umbilical cord” between the outboard power supply and this connector to provide the preamplifier with the clean, pure DC power it needs to do its job.

There is also an AC mains switch on the back of the outboard power supply. Switching the power supply on (assuming the preamplifier is connected with the umbilical cord) puts the preamplifier in standby mode. The preamplifier should also be in standby before power is switched off.

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