1 POWER BUTTON
Pressing this latching
power button connects the amplifier to the AC mains,
charges the power supply (which takes about five seconds), and places it in
standby. Having a true standby function keeps the sensitive voltage gain
stages warmed up and sounding their best at all times. Power consumption
when in standby is less than 100 watts.
Note that if the amplifier has been disconnected from the AC mains power
by depressing the front panel
power button or by unplugging it from the
AC outlet, it cannot respond to a remote turn-on command from a control
unit. If you wish the amplifier to turn on and off via the Proceed communi-
cations bus (or by a DC trigger), the amplifier needs to be in standby, with
this
power button engaged.
2 STANDBY BUTTON
Assuming that the power is on and the unit is in standby (see 1, above),
pressing the
standby button engages the output stage of the amplifier, tak-
ing it from standby to fully on . Pressing the standby button again will
toggle the amplifier back to standby. Power consumption when fully on and
at idle is less than 150 watts.
At your option, you may also toggle the amplifier between standby mode
and fully on by connecting a suitable 5-12V DC trigger such as can be pro-
vided by the Proceed PDSD or AVP to its remote trigger input .
