Upgrade your AV system to more immersive sound

The PA4 is the ideal upgrade for many AV amplifiers and receivers, ARCAM and others, past and present. Simply use your processor's preamp outputs to add extra channels of surround sound. With four channels you could add four ceiling speakers to an existing 5.1 system, or step up from 5.1.2 to 7.1.4, as long as your AV amplifier supports preamp outputs.

The natural partner for ARCAM Radia

With its sleek Radia design, the PA4 is the perfect aesthetic and technical match for other Radia products. It is the natural Class D partner for adding speakers to the AVA15, and can also add channels to the AVA25, AVA35, and AVP45.

Punchy power with channel versatility

The PA4 delivers 4 x 50 watts, ample for surround effect channels in most rooms. For added flexibility, the channels can be bridged to boost power to 2 x 100 watts, making future system upgrades easy.

Slim, cool, and easy to install

The compact 1U chassis is easy to rack mount and simple to house. It features 12V in and out triggers for remote power operation, ideal when the system lives in a dedicated utility space, and firmware updates are handled via USB. Highly efficient amplification reduces energy consumption and heat output, which is especially beneficial when units are stacked for multiroom use and helps deliver long-term reliability.
