9BSST THX FIVE CHANNEL POWER AMPLIFIER1 Introduction Thank you for choosing the 9BSST Five 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 Brystons most important resource, and your opinion is very much appreciated. Description The 9BSSTis a modular design 5 x 120 Watts per channel audio power amplifier. Each channel selects a balanced or sin- gle 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 9BSST may be controlled by a remote control voltage. The 9BSST 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 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 9BSST 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 equip- ment. Should your installation conditions be constricted, then additional forced air-cooling may be necessary. Bryston can provide an optional fan package if required. Any 9BSST channels thermally shutting down during operation indicates insuf- ficient cooling, and a remedy must be found for cooling the amplifier. Provide a minimum 6 space to the rear of the 9BSST for ventilation and dressing cables to and from the amplifier. Never operate the 9BSST in a vertical position. Wiring the 9BSST( 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 gauge wire. The speaker binding posts will accept wire up to 3 gauge in size. Bryston can custom build cables for your applica- tion. A/C power Before plugging in the power cord be sure your 9BSST is specified for the correct A/C voltagefor your locality. The volt- age is listed to the right of the power input connector. The circuit feeding the 9BSST should be sufficient so as not to cause the circuit breaker to trip. Note: the 9BSST when operated with all channels at maximum power into 4 ohm loads, can con- sume 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 conditionerswill notimprove the 9BSST 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.
