6BSST    

THREE CHANNEL POWER AMPLIFIER

1

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.
