The Bryston 4B³ gives you the power and control to drive demanding loudspeakers with confidence. It delivers 300 watts per channel into 8 ohms and up to 500 watts into 4 ohms, providing ample headroom for dynamic music and complex passages. Its dual-mono design gives each channel an independent power supply and transformer, helping maintain consistent performance when both channels are working hard.
Connect your preamplifier through balanced XLR or single-ended RCA inputs, and select between 23dB and 29dB gain to suit your system. Bryston's patented Salomie input circuit helps keep distortion and noise low, so you can hear the detail in your recordings without unwanted interference. If your setup requires more power, the 4B³ can also operate in bridged-mono mode with a compatible load.
The machined, anodized aluminum chassis is designed for dependable long-term use, while fanless convection cooling keeps mechanical noise out of your listening room. Microprocessor-controlled SoftStart helps manage the initial power draw at startup, and a DC trigger makes integration with compatible system controllers straightforward.
A strong choice for serious two-channel systems that need substantial power, low distortion, and reliable everyday operation.
