BRYSTON 2BSST AMPLIFIER DESCRIPTION:

The 2BSST is a duel mono design power amplifier consisting of two totally independent amplifiers with +/-58V power supply modules. The Bryston 2BSST will operate as a STEREO power amplifier or as a bridged MONO power amplifier. Each 2BSST channel provides input switching and connections for balanced (XLR type) or single ended (RCA style) input. Each 2BSST channel provides sensitivity selection for 1 Volt (29dB gain) or 2 Volt input sensitivity (23dB gain). The 2BSST has remote A/C power control using a low volt trigger input. (see Remote Power Control section.)

INSTALLATION SETUP and RECOMMENDATIONS:

Check the label next to the power input connector on the rear of the 2BSST and verify your amplifier complies to your local A/C voltage and frequency requirements.

The 2BSST is a convection cooled amplifier and requires the installation to allow for un-restricted air flow through the heat sinks. We recommend maintaining at least 3 inches of clear space to the sides of the amplifier, and if pos- sible that the 2BSST be on its own dedicated shelf. Install only horizontally with logo up. The 2BSST should not be installed near other heat sources like heating vents or radiators. Equipment mounted above the 2BSST should maintain at least 3 inches of clearance. The 2BSST should not be installed in tight enclosed areas.

(See INSTALLATION of 2BSST on page 3)

Bryston recommends that at least 6 inches of space be provided to the rear of the amplifier for properly dressing input, output and power cables. Speaker cables should be as short as possible. Use quality cables of at least 16 gauge . The 2BSST binding posts will accept stripped bare wire, pin connectors, spade lugs or banana plugs. Use gold plated connectors for lowest contact resistance. After all input cables and speaker output connections are correctly made, plug the power cable into the wall outlet. The power on/off switch is located on the front panel and is labeled 2BSST. Simply depress the switch to turn on and push again to turn off. The 2BSST may also be powered on using a low voltage trigger. (see Remote Power Control section.)

LED STATUS INDICATORS:

The 2B SST uses tri-color LED’s with green indicating NORMAL operation, FLASHING RED indicating overload or clipping, and ORANGE indicating thermal shutdown. Upon power-up the 2BSST LED’s will remain “RED” until all voltages stabilize, then the unit comes out of mute, and the LED’s turn GREEN.

Should the LED indicator flash RED or contain a substantial RED content when program is present, the program INPUT level is too high and the output can no longer accurately follow the input (CLIPPING). This condition may cause speaker damage if it continues. Reduce the input level until the 2BSST flashes RED only on the loudest passages in the program. Substantial clipping indicates the amplifier application will need either a more powerful amplifier or more efficient loudspeakers.

Should the LED’s turn ORANGE the 2BSST has shut down due to overheating. The 2BSST will reset itself when the heat sink temperature returns to a safe operating temperature. Thermal shutdown indicates the amplifier is incor- rectly installed and a remedy must be found to provide better cooling for the amplifier.
