6BSST THREE CHANNEL POWER AMPLIFIER Introduction Thank you for choosing the 6BSST Three 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 Bryston’s most important resource, and your opinion is very much appreciated. Description The 6BSST is a modular design 3 x 300W per channel audio power amplifier. Each channel selects a balanced or single ended input.
6BSST THREE CHANNEL POWER AMPLIFIER Rear Panel Input / Output Connections 1. Input Select Switch. Each 6BSST 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. ‘XLR’ type ‘TRS’ type ‘RCA’ type 3. Single Ended Input. ( Un-balanced input ) ( Imp.
6BSST THREE CHANNEL POWER AMPLIFIER 6. Output binding posts & polarity. The RED binding post is connected to the amplifier output. Connect to this post the (+) terminal on the loudspeaker. The BLACK binding post is connected to signal ground. Connect to this post the (-) terminal on the loudspeaker. When the polarity switch is set for 0 degrees (normal operation ) the output at the RED binding post is in phase with the input signal.
BSST THREE CHANNEL POWER AMPLIFIER 2 1 Front Panel 1. 'SST POWER' switch The front panel label 'SST POWER', is a touch sensitive membrane switch used to apply or remove a/c line power to the 6BSST circuitry. Push firmly the center of the switch until the power-up sequence begins. Push again and the 6BSST will power-down. ( Note: the rear circuit breaker must be on for the 6BSST to power-up) 2.
6BSST THREE CHANNEL POWER AMPLIFIER Power Control Panel 1. Master circuit - breaker. The 6BSST uses a magnetic-trip circuit breaker (1) to protect the amplifier. This switch should be ‘OFF’ when installing the 6BSST. When switched ‘OFF’ all A/C power is removed from the amplifier, including standby power. The circuit breaker is not the day to day power switch and should be switched and left ‘ON’ after the installation is complete.
6BSST THREE CHANNEL POWER AMPLIFIER Rack Mounting Instructions The 6BSST 19” version may be rack mounted with or without the ability to remove the channels. If removal of the channels is desired then the shipping screws securing the channels need to be removed.
