POWER  BUTTON
Pressing the latching 

button connects the amplifier to the AC mains,

turning it 

. Power consumption when fully on and at idle is approxi-

mately 140 watts for the BPA 2 and 210 watts for the BPA 3.

At your option, you may also toggle the BPA between a 

mode and

fully 

 by connecting its 

to the corresponding 

on a Proceed control unit such as the AVP.

When first powered up, the BPA will always go to fully 

, regardless of the

signal present at its 

. If the control unit then turns on,

the amplifier will remain on; thereafter, the two will remain in sync. If
power is removed from the BPA, it will automatically re-sync with the con-
trol unit in the course of normal operation. No user intervention is re-
quired, beyond simply turning the system on and off from the control unit.

Power consumption in 

mode is significantly reduced from fully

“on”—just a few watts for the circuitry which controls the turn-on proce-
dure.

Note that if the amplifier has been disconnected from the AC mains power
by depressing the front panel 

button, it cannot respond to a remote

turn-on command from a control unit.

INDICATOR LIGHT
The 

glows either amber or red, depending on the opera-

tional status of your BPA. Amber indicates that the BPA is 

and ready to
