14B SST Series Amplifier Introduction Thank you for choosing the 14B SST SERIES Stereo 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 14B SST The 14B SST is a dual channel 600 Watt audio power amplifier.
14B SST Series Amplifier Rear Panel Input / Output Connections Fig 1 2 1/4” PHONE PLUG 1 4 3 XLR TYPE RCA PLUG 5 1. Input Select Switch. Each SST channel gives the user the option of switching between either balanced input or single ended input. Input Sensitivity Selection. The optimum gain setting will depend upon the source pre-amp operating level, and or personal preference. The UNBAL setting is used when the source is single-ended, or from a transformer coupled balanced source.
14B SST Series Amplifier 5. Output binding posts. The RED binding post is the in-phase amplifier output. Connect to this post the (+) terminal on the loudspeaker. The BLUE binding post is the inverted-phase amplifier output. Connect to this post the (-) terminal on the loudspeaker. Note: At no time should either output be connected to a ground, or chassis. Failure of the amplifier may result. Never connect either output in parallel with another amplifier. The minimum recommended loudspeaker load is 4 ohms.
14B SST Series 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 soft start circuitry. Push firmly the center of the switch until the power-up sequence begins. Push again and the amplifier will power-down. ( Note: the rear circuit breaker must be on for the amplifier to power-up) 2.
14B SST Series Amplifier Power Control 1. Master circuit - breaker. The 14B SST amplifier uses a magnetic-trip circuit breaker (1) to protect the amplifier. This switch should be ‘OFF’ during installation. When switched ‘OFF’ all A/C power is removed from the amplifier, including standby power. The circuit breaker is not the power switch and should be switched to and left ‘ON’ after the installation is complete.
