Resumen del manual


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 eliminate 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 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 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 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. 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 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 (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 sufficient 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 7B SST Series Amplifier 2 Rear Panel Input / Output Connections 1. Input Select Switch. Each SST channel gives the user the option of switching between either balanced input or single ended input. 2. Balanced Input connector. ( Imp. 20k ) This input connector accepts standard ‘XLR’ or 1/4” TRS . Use quality, 100% shielded cables with gold plated connectors. 3. Single Ended Input. ( Un-balanced input ) ( Imp. 50k ) This input connector accepts standard ‘RCA’ or ‘Phono’ connectors. Use quality, 100% shielded cables with gold plated connectors. Balanced input Vs Single ended input: The balanced input requires a balanced pre-amp source. Balanced systems provide noise rejection from external electrical interference, so cable length can be very long ( 50m or longer ). The single ended or unbalanced input is provided for pre-amps without balanced output. Single-ended cables should be kept to 20’ (7m) or less. In general never use longer cables than necessary, never coil excess cable length, and keep signal wires away from AC power or speaker cables. 4. Input Sensitivity (Gain) Switch. The optimum gain setting will depend upon the source pre-amp operating level, and or personal preference. The 1v setting is used when the source is single-ended, or from a transformer coupled balanced source. This is the home theatre setting for single ended or un-balanced operation. The 1v setting provides the most amplifier gain - 29 dB. (1v in = 100w @ 8 ohms.) (noise -110 dB) The 2v setting is used when the sources output is actively Balanced. This is the home theatre setting for balanced operation Or use this setting with any systems where the volume control rotation is limited to the bottom half of the control or less. The 2v setting provides an amplifier gain - 23 dB. ( 2v in = 100w @ 8 ohms.) ( noise -113 d...
