All SST amplifiers are convection cooled. Each SST channel gives the user the option of switching between either balanced input or single ended input.

The RED binding post is connected to the amplifier output. The SST amplifier uses a magnetic-trip circuit breaker 1 to protect the amplifier.

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.

Ship the amplifier only in the original packing material, as the unit is not insurable by carriers otherwise. This warranty gives you specific legal rights and you may also have other rights which may vary from province to province and country to country.

Balanced systems provide noise rejection from external electrical interference, so cable length can be very long 50m or longer. Bryston will custom build cables for your application. Bryston can provide an optional fan package if required.

The speaker binding posts will accept wire up to 3 gage in size.

The control current is determined by the source equipment. Connect to this post the – terminal on the loudspeaker.


See figure brystln below. Never operate the amplifier in a vertical position. Spade lugs provide high contact area and secure fastening. See diagram for details.

Bridged W 8 ohms Max.

Gold plated spade lugs are available from Bryston. Cables should be kept as short as practical and should never be terminated with connectors that may become confused for AC power connectors. The 1v setting mannual used when the source is single-ended, or from a transformer coupled balanced source.

Lugs should be gold plated. Should your instillation conditions be constricted, then additional forced air-cooling may be necessary. Then power the unit up normally. For this reason do not install anything directly above it.

The 2v setting provides an amplifier gain – 23 dB. Should thermal shutdown occur, the channel will mute, and the channel LED will turn orange indicating this condition. Note that copper wire is malleable and may require further tightening after the initial installation.

Input Sensitivity Gain Switch. Bryston welcomes any suggestions you brystln have, or comments regarding the operation of your amplifier. Clipping flashing red Clipping occurs when the channel output level no longer can follow the level increase at the input Overdriven input condition. This warranty is considered void if the defect, malfunction 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.

In the event of a defect or malfunction, Bryston will remedy the problem by repair or replacement, as we deem necessary, to restore the product to full performance. The amplifier will now power-up only when the control voltage is present on.

When the channel has cooled to a safe operating condition the channel will return to normal operation. Do not install directly above other heat generating equipment. Push again and the amplifier will power-down.


Use paired wire of 22 to 18 gage sufficient in length between the source device and the SST amplifier.

The balanced input requires a balanced pre-amp source. Gold plated locking banana plugs are available from Bryston. The circuit feeding the 4B SST should be sufficient so as not to cause the circuit breaker to trip 15 amp min. Tampering by persons other than factory authorized service personnel, or failure to fully comply with Bryston operating instructions, voids the warranty. Do not over tighten or the binding post may become damaged. Graph shows that distortion is essentially unaffected by load.

Momentary clipping can be tolerated, however it indicates that maximum undistorted power has been surpassed and potential speaker damage may result if overload conditions persist. Balanced input Vs Single ended input: Master circuit – breaker.

In general never use longer cables than necessary, never coil excess cable length, and keep signal wires away from AC power or speaker cables.


In the unlikely event you have a problem and must return it for service you must use the proper packing material. The SST control circuitry itself draws less than 2 mA from the control current when operating.

Combinations may be used when bi-wiring.

Installation see rack mounting section if applicable Ventilation. Push firmly the center of the switch until the power-up sequence begins.
