28B-SST Amplifier
1
Introduction
Thank you for choosing the 28B-SST C-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 28B-SST
The 28B-SST is a single channel 1000 Watt audio power amplifier. The 28B-SST selects a balanced (3 pin XLR or ¼"
phone plug) or single ended (RCA/phono plug) input. A gain of 29dB or 23dB may be selected. The 28B-SST includes
‘soft start’ power control circuitry to eliminate high inrush currents when A/C power is applied. The power up or turn-on of
the 28B-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 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 28B-SST amplifier is convection cooled.
Unrestricted air-flow across the 28B-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
generating equipment. Should your instillation conditions be constricted, then additional forced air-cooling may be neces-
sary. 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
ventilation and dressing cables to and from the amplifier.
Never operate the amplifier in a vertical position.
Wiring the 28B-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 28B-SST amplifier is specified for the correct ac voltage for your locality.
The voltage is listed on the label found at the upper right of the rear panel. The circuit feeding the 28B-SST should be suf-
ficient so as not to cause the circuit breaker to trip (15 amp min.). Note: the 28B-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.
