7B SST Series Amplifier1 Introduction
Thank you for choosing the 7BSST 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 Brystons most important resource, and your opinion is very much appreciated.
Description 7B SST
The 7B SSTis a single channel mono 600 Watt audio power amplifier. The 7BSST 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 mustuse 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 wiresshould 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 voltagefor 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 conditionerswill notimprove 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
