Stereo class-D amplifier

This two-channel class-D power amplifier delivers 50 watts per channel into 8-ohm loads or 65 watts per channel into 4-ohm loads. It suits installers building distributed whole-house audio systems who need a compact, rack-friendly stereo amp with flexible trigger options.

Power ratings and bridge mode

Each channel provides 50 watts RMS into 8 ohms and 65 watts RMS into 4 ohms for typical multi-room zones. Bridging the output yields 120 watts into a single 8-ohm load for a larger zone or subwoofer, while the buffered loop line output passes the signal to additional amplifiers.

Trigger and power-on modes

The unit offers always-on, signal-detection and 12-volt triggered power-on states plus a 12-volt trigger output for sequencing other gear. Buyers who need network streaming, built-in DSP or more than two channels should consider a different product class.

Questions about this item

Will the 100 W per channel into 8 Ω from this amp overdrive older 50 W bookshelf speakers?

Each channel delivers up to 100 watts RMS into 8 ohms, so the amp can supply more power than 50 W speakers are rated for; keep the volume control low enough to avoid clipping and driver damage.

How can I verify the 120 W bridged output into 8 Ω is active after wiring?

Set the rear bridge switch, connect a single 8 ohm speaker across the designated terminals, play program material and confirm clean output; the front power LED stays solid when the amplifier is operating normally.

Does the box include the 4-pole speaker connectors and 12 V trigger cable, or must I buy them?

The detachable 4-pole speaker connectors are included; a 12 volt trigger cable is not supplied and must be purchased separately.
