BZBGear BG-AMPC40 40W 70V/100V Amplifier with Mic Ducking

The BG-AMPC40 drives a 70V or 100V distributed speaker line at 40W, switchable between the two, which is the usual requirement in a retail floor, a lobby or a warehouse where speakers are daisy chained across a long run.

It takes two stereo inputs, a TOSLINK digital input and a balanced 3-pin mic input with selectable 48V phantom power and noise suppression. Ducking pulls the music down when the mic opens, and a mic mixer and EQ are included. A rotary knob sets one of 16 IR ID codes so several amplifiers in one building can be addressed separately, and RS-232 is there for a control system.
