14B-SST Series Amplifier Introduction Thank you for choosing the 14B-SST 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 Figure 1 1. Input Select Switch. The INPUT SELECT switch gives the user the option of switching between either balanced input or single ended input. 2. Input Sensitivity Selection. This switch changes the gain of the amplifier. ● The 1v setting has a gain of 29dB ● The 2v setting has a gain of 23dB The optimum gain setting will depend upon the source pre-amp operating level, and or personal preference.
14B-SST Series Amplifier 6. 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 Power Control (refer to figure 1 on page 2) 7. Master circuit - breaker. The 14B-SST amplifier uses a magnetic-trip circuit breaker 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.
14B-SST Series Amplifier 14 13 FRONT PANEL (refer to illustration above) 13. ‘14B-SST’ power switch The front panel label ‘14B-SST’, is a push on push off switch used to apply or remove AC line power to the soft start circuitry. ( Note: the rear circuit breaker must be on for the amplifier to power-up) 14. LED Indicators The 14B-SST has an LED indicator to monitor the following conditions: Unlit indicates the amplifier is turned off.
