3B SST3

The Bryston 3B³ is a dual-channel stereo power amplifier designed for audio and home cinema systems requiring substantial power without compromising sonic accuracy, stability or long-term reliability.

Its active, extremely low-distortion input buffer is complemented by balanced and unbalanced inputs, with selectable 23dB or 29dB gain for flexible system matching. Regulated power supplies are provided to all voltage-gain stages, while each channel has an independent power supply for improved separation and consistent performance.

The amplifier is housed in a robust, fully aluminium chassis and uses convection cooling, eliminating the need for fans or other moving parts. This provides silent operation and effective thermal management for reliable long-term use.

A bridging switch allows the two channels to be configured as a single 400W mono amplifier when additional power is required.
