Caution!

Also, it is a good practice to physically disconnect any and all valuable electronics from the AC mains during electrical storms, as a lightning strike anywhere near your home can put a tremendous surge on the AC mains that can easily damage any piece of electronics, no matter how well designed and protected. The best protection in the case of severe electrical storms is to simply remove the electronics from any connection with the power grid.

2Select button

The Select button is used (along with the Mode button) when conﬁguring the ampliﬁer for either balanced or single-ended operation. It is also used when conﬁguring the turn-on delay or ampliﬁer number for connection with a Classé preampliﬁer by the DC Trigger or CAN Bus control systems.

3Channel status LED indicators

Your ampliﬁer has two front-panel Channel LED indicators. There is a separate LED to indicate the use of either the balanced (XLR) or single- ended (RCA) input.

These indicators are also used to indicate fault conditions in your ampliﬁer, should any ever arise. If either of the Channel LED indicators blinks red, there is a problem with your ampliﬁer.

If you see any Channel LED Indicator blinking red, please disconnect the ampliﬁer from the AC mains immediately and check that all external connections are cleanly made and secure. If the AC mains are not easily accessible, you can press and hold the Standby button for three seconds to reset the ampliﬁer. If no fault is immediately obvious, please call your authorized Classé dealer for assistance.
