Front Panel
1 Standby button & LED indicator
The front panel Standby button will toggle the preampli–er between
operate, its fully operational state, and a standby mode that leaves the
preampli–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).
The current state of the preampli–er is indicated by the LED indicator in
the center of the standby button. When the unit is powered and switched
on, the state of this LED indicates the following:
• on =
standby
• —ashing
(on power-up) = initialization
• off =
operate
• on
(dim) = display timeout
• —ashing
(after power-up) = AC mains voltage out of range
If you are planning not to use the preampli–er for an extended period of
time, e.g. vacation or other travel, we suggest you disconnect it from the
AC mains. Please be certain that the preampli–er is turned off 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 damage any piece of electronic equipment, no matter how
well designed and protected. The best protection in the case of severe
electrical storms is simply to remove the electronics from any connection
with the power grid.
