Persistent Thermal shutdown indicates steps need to be taken to increase airflow across the channel or channels heat sink. For this reason do not install anything directly above it.

Do not install directly above other heat generating equipment.

Clipping flashing red Clipping occurs when the channel output level no longer can follow the level increase at the input Overdriven input condition. Should your instillation conditions be constricted, then additional forced air-cooling may be necessary. The optimum manjal setting will depend upon the source pre-amp operating level, and or personal preference. Bridge mode is for mono operation.

Never operate the amplifier in a vertical position. Check that the voltage rating on the label conforms with your locality. The single ended or unbalanced input is provided for pre-amps without balanced output.

Combinations may be used when bi-wiring. Warranty coverage is automatic and ssst with the original date of manufacture which is kept on file at Bryston. In the unlikely event you have a problem and must return it ss service you must use the proper packing material. This is the home theatre setting for balanced operation Or use this setting with any systems where the volume control rotation is limited to the bottom half of the control or less.


When the channel has cooled to a safe operating condition the channel will return to normal operation.

gryston Each channel selects a gain of 29dB 1v or 23dB 2v. This is the home theatre setting for single ended or un-balanced operation. The voltage is listed on the label found at the upper right of the rear panel. Note that copper wire is malleable and may require further tightening after the initial installation. Ship the amplifier only in the original packing material, as the unit is not insurable by carriers otherwise. Push firmly the center of the switch until the power-up sequence begins.

Push again and the amplifier will power-down.

Tampering by persons other than factory authorized service personnel, or failure to fully comply brysotn Bryston operating instructions, voids the warranty.

The above noise ratings represent minimum readings, actual readings may be better. If both channel LED indicators are unlit the amplifier probably needs only to be powered on.

Should thermal shutdown occur, the channel will mute, and the channel LED will turn orange indicating this condition. The speaker binding posts will accept wire up to 3 gage in size. Gold plated spade lugs are available from Bryston. Never lift the safety ground to the amplifier nor remove the ground pin from the plug. See diagram for details. Should the breaker trip, lower or remove the amplifier input signals.

Balanced systems provide noise rejection from external electrical interference, so cable length can be very long 50m or longer. Wiring the SST amplifier also see rear panel description Speaker wires should be as short as practical.

Connect to this post the – terminal on the loudspeaker. When the power supplies have stabilized the channel will come out of mute hryston the LED will change to green normal operation. Any amplifier that is constantly operated into clipping indicates a more powerful amplifier is needed for that application. Master circuit – breaker. Different input configurations result in slightly different noise readings. The balanced input requires a balanced pre-amp source.


The SST amplifier uses a magnetic-trip circuit breaker 1 to protect the amplifier. Lugs should be gold plated. Momentary clipping can be tolerated, however it indicates that maximum undistorted power has been surpassed and potential speaker manuwl may result if overload conditions persist. Spade lugs provide high contact area and secure fastening. Also see installation section on ventilation. The SST control circuitry itself draws less than 2 mA from st control current when operating.

This warranty is considered void if the defect, bruston or failure of the product or any component part was caused by damage not resulting from a defect or malfunction or abuse while in the possession of the customer.

Bridged W 8 ohms Max. Balanced input Vs Single ended input: Installation see rack mounting section if applicable Ventilation.

All SST amplifiers are convection cooled. It’s a community-based project which helps to repair anything.

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. 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.
