7B SST Series Amplifier

Introduction

Thank you for choosing the 7B SST SERIES mono block Power Amplifier.

Bryston welcomes any suggestions you may have, or comments regarding the operation of your amplifier. We consider you, our customer, to be Bryston’s most important resource, and your opinion is very much appreciated.

Description 7B SST

The 7B SST is a single channel mono 600 Watt audio power amplifier. The 7B SST selects a balanced or single ended input and a gain of 29dB(1v) or 23dB(2v) may be selected. The 7B SST includes ‘soft start’ power control circuitry to elim- inate high inrush currents when A/C power is applied. The power up or turn-on of the 7B SST may be activated by a remote control voltage 4v to 12v ac or dc.

Warranty ( see back page for details )

Shipping Box & Packing Material

Please keep the original shipping box and all packing material. This will ensure the amplifier is protected in future trans- port. In the unlikely event you have a problem and must return it for service you must use the proper packing material. Ship the amplifier only in the original packing material, as the unit is not insurable by carriers otherwise.

Installation ( see rack mounting section if applicable )

Ventilation. The most important installation consideration is ventilation. The 7B SST amplifier is convection cooled. Unrestricted air-flow across the 7B SST heat sinks is a must. For this reason do not install anything directly above it. Allow 3.5’ (2u) to 5” (3u) inches of space above and to the sides of this amplifier. Do not install directly above other heat gener- ating equipment. Should your instillation conditions be constricted, then additional forced air-cooling may be necessary. Bryston can provide an optional fan package if required. Thermal shut down during operation indicates insufficient air flow, and a remedy must be found for cooling the amplifier. Provide a minimum 6” space to the rear of the amplifier for ventila- tion and dressing cables to and from the amplifier.

Never operate the amplifier in a vertical position.

Wiring the SST amplifier ( also see rear panel description )

Speaker wires should be as short as practical. Use quality wire, and if runs are more than 3 meters use at least 12 gage wire. The speaker binding posts will accept wire up to 3 gage in size. Bryston offers speaker cables and amp interconnects for your application. Check our website under products/cables (www.bryston.ca) for more information.

A/C power

Before plugging in the power cord be sure your 7B SST amplifier is specified for the correct a/c voltage for your locality. The voltage is listed on the label found at the upper right of the rear panel. The circuit feeding the 7B SST should be suf- ficient so as not to cause the circuit breaker to trip (15 amp min). Note: the 7B SST when delivering maximum power into a 4 ohm load, will consume all the available power in a normal household circuit, therefore a dedicated electrical circuit may be necessary with this situation. Never lift the safety ground to the amplifier nor remove the ground pin from the plug.

Power line conditioners will not improve the 7B SST amplifier performance, in fact most of the time they restrict the flow of current to the amplifier, reducing performance at higher output levels

7B SST specifications

The Bryston 7B SST is a high-performance power amplifier renowned for its exceptional sound quality and robust build. As a part of Bryston’s SST (Super Silent Technology) line, the 7B SST represents a culmination of innovative engineering and unwavering dedication to audio fidelity, making it a favored choice among audiophiles and professionals alike.

One of the standout features of the 7B SST is its impressive power output, delivering 800 watts per channel into 4 ohms and 400 watts per channel into 8 ohms. This ensures that it can drive even the most demanding loudspeakers with ease, offering the headroom necessary for dynamic music playback. The amplifier employs a fully balanced differential design, minimizing noise and distortion, which results in cleaner, more accurate sound reproduction.

The 7B SST utilizes advanced technologies such as Bryston’s proprietary output devices, which contribute to its high performance and reliability. These output devices are designed to handle higher current levels, reducing the chances of clipping and ensuring that high volumes can be achieved without loss of quality. Additionally, the amplifier features a unique design that allows it to maintain stability and performance across a wide range of speaker impedances.

Thermal management is another key aspect of the 7B SST’s design. The unit is equipped with a robust heat sink system that allows for efficient dissipation of heat during operation, ensuring that the amplifier remains cool even under strenuous conditions. This is complemented by a toroidal transformer that provides excellent voltage regulation while minimizing electromagnetic interference.

Connectivity options on the 7B SST are versatile, including balanced XLR and single-ended RCA inputs. This flexibility allows for seamless integration into various audio systems, whether in home theaters or professional studio settings. The amplifier also boasts an impressive signal-to-noise ratio, providing a silent background for delicate musical details to emerge.

In summary, the Bryston 7B SST is a powerful amplifier that combines cutting-edge technology with exceptional performance characteristics. Its ability to deliver high-quality sound, even under demanding conditions, makes it a prized asset for any serious audio setup, ensuring that users experience their music as the artist intended. Its robust construction and reliability further underscore Bryston's reputation for quality in the world of audio amplifiers.
