1Standby button & LED indicator

The front panel Standby button will toggle the amplifier between operate, its fully operational state, and a standby mode that leaves the amplifier off, yet ready to respond to system commands via any of the supported control options (e.g. IR input, DC trigger, CAN Bus, or RS-232).

The current state of the amplifier is indicated by the LED indicator in the center of the Standby button. The state of this LED indicates the following:

•	on	=	standby
•	flashing (on power-up)	=	initialization
• off + Channel LED on		=	operate
•	flashing (after power-up)	=	AC mains voltage out of range

When in standby, the amplifier’s gain stages are powered down. Only a small power supply and control circuit remain on, consuming relatively little power. Fortunately, since the output stages by their nature conduct a great deal of current, they warm up and sound their best very quickly.

If you are not going to use the amplifier for an extended period of time, perhaps while traveling for a vacation, we suggest you disconnect it from the AC mains. Please be certain that the amplifier is in standby prior to disconnecting it from the AC mains.

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.
