Compact 40W amplifier for distributed audio

The BG-AMPC40 is a 2-channel Class-D amplifier that delivers 40 watts at switchable 70V or 100V outputs. It suits installers who need a small 1U unit for background music or paging in retail, education or hospitality spaces where full-sized amplifiers will not fit.

Handles line, optical and mic sources with ducking

Two RCA inputs, a 3.5mm jack, a TOSLINK port and a balanced microphone input with selectable 48V phantom power provide flexible source mixing. The built-in ducking function automatically lowers background audio when the microphone is active, and the 3-level mic mixer keeps levels manageable for announcements.

Metal chassis with captive-screw outputs

The 130 x 44 x 144 mm metal enclosure weighs 860 g and uses 3-pole 3.81 mm captive screw connectors for secure speaker wiring. Front-panel push buttons handle input selection, volume, bass and treble, while RS232, IR and 16 selectable IR ID codes allow integration into larger control systems.

Questions about this item

Will the BG-AMPC40 work with my existing 70V ceiling speakers and passive volume controls?

Yes — the amplifier delivers 40 Watts at either 70V or 100V, so it can drive your 70V speaker line directly without an additional transformer.

How can I confirm the amplifier is operating correctly once installed?

The front-panel LEDs show power and signal status; you can also query the unit over RS-232 for real-time volume, input and fault reports.

What cables and accessories are included, and what must I source separately?

The box contains the amplifier, IR remote, rack ears and a 3-pin 3.81 mm captive-screw plug for the speaker output; you need to supply RCA, 3.5 mm, TOSLINK or MIC cables and any 48 V phantom-powered microphone.
