6BSST

THREE CHANNEL POWER AMPLIFIER

Introduction

Thank you for choosing the

6BSST Three Channel 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

The

6BSST is a modular design 3 x 300W per channel audio power amplifier. Each channel selects a balanced or single

ended input. Each channel selects a gain of 29dB(1v), 23dB(2v) or 17dB(4v). Each channel input may be operated invert-

ed or non-inverted operation(0 or -180 degrees). The power up of the 6BSST may be controlled by remote control voltage.

The 6BSST includes ‘soft start’ power control circuitry to eliminate high inrush currents when A/C power is applied.

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 transport.

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 6BSST is a convection-cooled amplifier.

Unrestricted air-flow across its 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 generating

equipment. Should your instillation conditions be constricted, then additional forced air-cooling may be necessary. Bryston

can provide an optional fan package if required. Any 6BSST channels thermally shutting down during operation indicates

insufficient cooling, and a remedy must be found for cooling the amplifier. Provide a minimum 6” space to the rear of the

6BSST for ventilation and dressing cables to and from the amplifier.

Never operate the 6BSST in a vertical position.

Wiring the 6BSST ( 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 gauge

wire. The speaker binding posts will accept wire up to 3 gage in size. Bryston can custom build cables for your applica-

tion.

A/C power

Before plugging in the power cord be sure your 6BSST is specified for the

correct a/c voltage for your locality. The voltage

is listed to the right of the power input connector. The circuit feeding the 6BSST should be sufficient so as not to cause the

circuit breaker to trip. Note: the 6BSST when operated with all channels at maximum power into 4 ohm loads, can 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 or remove the ground pin from the plug.

Power line conditioners

will not improve the 6BSST performance, in fact most of the time they restrict the flow of cur-

rent in the power line to the amplifier, reducing performance at high output levels.
