Page 3: General Introduction
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. The 14B SST can accept a balanced (3-pin XLR connec- tor) or single ended input (RCA or phono connector) and can be set to a gain of 29dB (sensitivity = 1V) or 23dB (sensitivity = 2V). The 14B-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 14B-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 14B-SST amplifier is convection cooled. -

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. Use the 2v setting with any systems where the volume control rotation is limited to the bottom half of the control or less. 3. Balanced Input connector. (input imp 58K each leg) This input connector accepts standard ‘XLR’ or 1/4” Phone jack (Tip-Ring-Sleeve) . Use quality, 100% shielded cables with gold plated connectors. 4. Single Ended Input. ( Un-balanced input) ( Imp. 50K ) This input connector accepts standard ‘RCA’ or ‘Phono’ connectors. -
Page 5: Output Binding Posts
The BLUE binding post is the inverted-phase amplifier output. Connect to this post the (-) terminal on the loudspeak- 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. The Output binding posts provide three different interconnect options. Combinations may be used when bi-wiring. See fig- ure 2 below. Cables should be kept as short as practical and should never be terminated with connectors that may become confused for AC power connectors. Cables should be dressed away from input and power cables. ● Banana plugs offer a quick disconnect option. Before inserting a banana plug into the binding post be sure to tighten the post nut to avoid rattling and to provide full insertion of the banana plug. Gold plated locking banana plugs are available from Bryston. ● S pade lugs provide high contact area and secure fastening. Lugs should be gold plated. See diagram for details. Post diameter is 5/16’ ( 8mm ), lug width 5/8” (16 mm). Gold plated spade lugs are available from Bryston. ● Stripped bare wire up to 3 gage can be inserted through the hole in the binding post and held in place by tightening the post knob. Additional tightening pressure can be achieved using a coin in the slots of the knob. Do not over tighten or the binding post may become damaged. Note that copper wire is malleable and may require further tightening after the initial installation. Spade lug dimensions... -

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. Use the 14B-sst front panel power switch or an external control voltage to Power-up or Power-down the amplifier. Should the breaker trip, lower or remove the amplifier input signal (also see section 9 below). Switch the breaker to the ‘ON’ position. Then power the unit up normally. The circuit breaker must be ‘ON’ at all times for the 14B-SST amplifier to operate. 8. AC power input. On the rear panel is provided a high current plug for the power cord receptacle. Check that the voltage rating on the label (item 12 in figure 1, page 2) conforms with your locality. With the circuit breaker ‘OFF’ insert the power cord into the 14B- SST amplifier, then plug the other end to an appropriate A/C power outlet. Switch the circuit breaker to on and observe the LED labeled "Line Voltage Status Indicator". 9. LINE VOLTAGE STATUS INDICATOR This LED will be on anytime the amplifier is plugged into a source of electrical power. Normally the LED will be green, and it must be green for the amplifier to power on. -
Page 7: Front Panel Description
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: indicates the amplifier is turned off. nlit indicates the amplifier is muted (in a power-up sequence) - i ndicates the amplifier operation is normal. Reen - indicates the amplifier clipping. lashinG indicates channel thermal shutdown. RanGe Power up sequence After pushing the 'SST POWER' switch, the LED will turn from unlit to red (mute). When the power supply has stabilized the amplifier will come out of mute and the LED will change to green (normal operation). Unlit LED ( power off ) The 14B-SST LED when unlit indicates no A/C mains power is present and the amplifier probably needs only to be powered on or the rear panel circuit breaker is switched off. Should the amplifier not power on when the power switch is pushed see the installation instructions. -
