INTRODUCTION
Thank you for choosing the 6BSST2 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
6B
SST
2
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
inverted or non-inverted operation(0 or -180 degrees). The power up of the 6BSST may be controlled by remote control
voltage. The
6B
SST
2
includes ‘soft start’ power control circuitry to eliminate high inrush currents when A/C power is applied.
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, ship the amplifier only in the original packing mate-
rial, as the unit is not insurable by carriers otherwise.
INSTALLATION & VENTILATION
The most important installation consideration is ventilation. The
6B
SST
2
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
6B
SST
2
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
6B
SST
2
for ventilation and
dressing cables to and from the amplifier.
Never operate the 6B
SST
2
in a vertical position
.
SPEAKER WIRES
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 application.
A/C POWER
Before plugging in the power cord be sure your
6B
SST
2
is specified for the
correct a/c voltage
for your locality. The voltage
is listed on the data plate located on the Power Inlet Panel (see page 4). The
6B
SST
2
when operated with all channels at
maximum power 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.
FUSES
When replacing fuses, first power down the amplifier and then disconnect the power cord from the amplifier. Use a 3/16"
blade screw driver to rotate the fuse caps (see Back Page for fuse locations) approsimately 30 degrees counter-slockwise
to release locking mechanism and then pull the fuse holder out of its socket. It is recommended that if you have to replace
a fuse, that you replace the pair of fuses for the affected channel. Use fast acting 4A/250V fuses such as Littelfuse 217004.
A/C POWER LINE CONDITIONERS
Bryston urges caution in choosing a power conditioner for your audio/video system. Large power amplifiers can draw very
substantial current from the wall plug, and many so-called power conditioners can in fact hinder the supply of current by
inserting resistances in series with the line cord. However, there are now power conditioners that can reduce or eliminate
RF and 'hash' from the AC supply and may actually improve current delivery to your system. This type of power condi-
tioner (exemplified by 'TORUS' Power Conditioners) uses the energy storage in a large toroidal tranformer to provide high
instantaneous power and reduce the substantial AC output resistance of the wall socket and house wiring. This resistance
can be in the range of 0.5 to 1 Ohm and is typically reduced to only a few milliOhms by the Power Conditioner. That in turn
considerably reduces Voltage drop in the power line on high current surges and quite substantially increases the stability
of the power line improving audio (and video) focus, precision and clarity.
