Bryston 7B (2.0) Mono Power Amplifier

Bryston 7B Cubed – 600 Watt Mono Power Amplifier for uncompromising sound control

The Bryston 7B Cubed is an uncompromisingly designed mono power amplifier for demanding hi-fi systems, combining enormous power reserves with precise and dynamic sound reproduction. As a powerful evolution within the Cubed series, this amplifier is designed to effortlessly control even demanding loudspeakers and reproduce music with high fidelity and exceptional dynamics.

With 600 watts at 8 ohms and up to 900 watts at 4 ohms, the 7B Cubed boasts ample power reserves. Even during quiet passages, the amplifier operates with sensitivity, enabling detailed reproduction of nuances and musical subtleties. Conversely, sufficient power is always available for dynamic transients, allowing for the controlled driving of even complex speaker loads.

A key factor in the high performance is the specially developed power supply with its particularly efficient transformer. This sophisticated power supply supports the superior operation of the mono power amplifier and helps to ensure stable and controlled performance even at high volume levels.

The patented Salomie circuit, a feature of all Bryston Cubed series amplifiers, is also employed. Together with the meticulously designed amplifier architecture, it enables low-noise and low-distortion signal processing.

For flexible integration into high-end systems, the Bryston 7B Cubed features both balanced XLR and unbalanced RCA inputs. Two pairs of speaker terminals simplify connection and offer additional installation flexibility. The gain is switchable between 23 dB and 29 dB, allowing for adaptation to different preamplifiers and system configurations.

In terms of noise level, the mono amplifier is consistently designed for use in high-quality listening environments. Convection cooling requires no fan and is therefore exceptionally quiet. A soft-start microprocessor controls the power-on process and prevents unnecessarily high loads on the power grid during startup.

For convenient integration into automated systems, the 7B Cubed features a DC trigger for automated switching on and off. Its standby power consumption is less than 500 mW, thus supporting efficient standby operation.

The robust housing made of machined and anodized aluminum underscores the amplifier's high-quality design. The 7B Cubed is available with a choice of silver or black front panel and in 18-inch or 19-inch rack-mount versions. The 19-inch version also features front-mounted handles.

The Bryston 7B Cubed mono power amplifier combines enormous output power, high current delivery, and precise signal processing with Bryston's typical robust construction. It provides a compelling foundation for controlled, dynamic, and detailed music reproduction, especially for demanding loudspeakers and performance-oriented stereo systems.
