1POWER 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 150 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.

2STANDBY 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 250 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.

Note that pressing the standby button has no effect until after the power supply is fully charged.
