40 W Plenum Audio Amplifier

This 40 W plenum-rated amplifier delivers 40 Watts of power for distributed audio systems. It accepts two analogue audio inputs with independent volume controls and includes a 3.5 mm stereo port plus RCA left/right connections. Automatic shutdown with instant wake reduces energy draw when no signal is present.

Installers needing plenum-rated safety

The unit carries TUV listing to UL 60065 and meets FCC and plenum requirements, making it suitable for in-ceiling or plenum-space deployment. Buyers who require more than 40 W output, digital inputs, or multi-zone matrix switching should consider alternative products.

40 W output power

The 40 W rating determines how many speakers can be driven at the required volume level. Verify that this power figure matches the load and SPL targets of the installation before purchase.

Questions about this item

What speaker connections does the 40100 amplifier require?

Connect two speakers to the 8-pin terminal block using the four dedicated speaker pins.

Can I keep my existing RCA source and 3.5 mm source connected at the same time?

Yes, the amplifier provides one RCA pair and one 3.5 mm stereo input, each with its own volume control.

How do I confirm the 40 W amplifier is operating correctly after installation?

Verify audio plays through both speakers, check that the unit wakes instantly from automatic shutdown when a signal is present, and ensure no distortion is audible at normal listening levels.
