Bryston 3B Dual-Mono Amplifier
A Legacy of Power and Precision
The Bryston 3B Dual-Mono Amplifier is the modern evolution of a design that dates back to 1973, when Bryston first introduced the PRO 3. Over nearly five decades, this amplifier has been refined into a high-performance, dual-mono powerhouse, offering 200W per channel into 8Ω (300W into 4Ω). With its fully independent power supplies, shallow depth design, and the renowned Cubed Series Salomie circuit, the 3B³ delivers exceptional clarity, detail, and musicality, making it ideal for audiophiles and professional installations alike.
Advanced Design & Uncompromising Performance
-
True Dual-Mono Architecture – Each channel operates independently with its own power transformer, ensuring superior channel separation and dynamic accuracy.
-
Exceptional Power Delivery – 200W into 8Ω and up to 300W into 4Ω per channel, delivering effortless dynamics.
-
Patented Salomie Circuit – Found in all Cubed Series amplifiers, minimizing distortion (<0.005% THD+N, 20Hz-20kHz @ Rated Power, 8Ω) for pure, uncolored sound.
-
Ultra-Wide Frequency Response – Extending from <1Hz to 100kHz (-3dB) for full-range accuracy.
-
Switchable Gain – Choose between 23dB or 29dB gain for precise system matching.
Superior Build & Silent Operation
-
Balanced XLR & Single-Ended RCA Inputs – Ensuring compatibility with various preamplifiers and sources.
-
Fully Convection-Cooled – No fans, ensuring silent operation and long-term reliability.
-
SoftStart Microprocessor-Controlled Startup – Prevents circuit breaker trips and extends component lifespan.
-
Machined & Anodized Aluminum Chassis – Enhancing durability and shielding from external interference.
-
Ultra-Low Noise Floor – RCA: < -106dB | XLR: < -111dB, revealing every detail in your recordings.
-
DC Trigger – Enables automated turn-on and turn-off for seamless integration.
-
Energy Efficient – Less than 500mW standby power consumption.
