6 DC 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:

7RS 232 Control Port

This DB-9 connector has two purposes:

•downloading new operating software into your amplifier (should new features ever be added, for example)

•for external control of your amplifier by systems such as AMX®, Crestron™ and Control 4™

For more information, please contact your dealer and ask about home automation systems.

8 USB Control Port

The USB connector provides the same functionality as the DB-9 connector described above. It is compatible with the USB ports on PCs and may obviate the need for a USB to RS-232 adaptor.

9AC Mains Input

An IEC standard power cord (supplied) is used with the CA-M600/CT-

M600. Plug the cord into the IEC receptacle on the rear panel, and the other end into a suitable wall outlet.

10AC Mains Fuse

Your Classé power amplifier has an AC mains fuse, accessible on the rear panel. If you suspect that your AC fuse has blown, disconnect your amplifier from the AC mains, as well as from its input connections and speaker connections, and refer to the appropriate item of the section entitled Troubleshooting.
