1 Standby button & LED indicator
e front panel Standby button will toggle the amplifi er between operate,
its fully operational state, and a standby mode that leaves the amplifi er 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).
e current state of the amplifi er is indicated by the LED indicator in the
center of the Standby button. e state of this LED indicates the
following:
• on = standby
• fl ashing (on power-up) = initialization
• off + Channel LED on = operate
• fl ashing (after power-up) = AC mains voltage out of range
When in standby, the amplifi er’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 amplifi er 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 amplifi er 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. e best protection in the case of severe electrical
storms is to simply remove the electronics from any connection with the
power grid.
