Front Panel
1 Standby 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.
