Our thoughts

A five-channel power amplifier that lets an AV receiver hand off the heavy lifting, with full rated output all the way down to 5 Hz.

Direct coupling removes capacitors and inductors from the audio path, so the aim is fewer components between your receiver and the speakers. Each channel has its own secondary winding on an encapsulated toroid, designed to keep channels from sharing one supply. Balanced XLR inputs, built on discrete circuits, take a balanced feed from a preamp or processor.

It suits home theatre systems where the AV receiver is the hub and the speaker array needs dedicated power, particularly surround and height layouts. Auto turn-on from an audio signal or 12V trigger lets it follow the receiver's lead. Our team can talk through how it connects to your receiver and how your speakers' impedance affects the decision, by phone or in person.
