7B SST Series Amplifier
Introduction
Thank you for choosing the 7B SST 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 7B SST
The 7B SST is a single channel mono 600 Watt audio power amplifier. The 7B SST 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

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 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 7B SST amplifier is convection cooled. Unrestricted
Never operate the amplifier in a vertical position.
Wiring the 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 7B SST amplifier is specified for the correct a/c voltage for 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 conditioners will not improve 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
