3B SST and 4B SST Series Amplifiers

6. Output binding posts.

The RED binding post is connected to the amplifier output. Connect to this post the (+) terminal on the loudspeaker. The BLACK binding post is connected to signal ground. Connect to this post the (-) terminal on the loudspeaker.

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.

1. 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.

2. Spade 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.

3. 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.

3B SST, 4B SST specifications

The Bryston 4B SST and 3B SST power amplifiers are renowned in the audio industry for their exceptional performance and reliable build quality. Designed for both audiophile and professional applications, these amplifiers bring out the finest detail in music while delivering high power and low distortion.

One of the main features of the Bryston 4B SST is its power output capability. It can deliver up to 300 watts per channel into 8 ohms, making it an ideal choice for driving demanding speakers with ease. The 3B SST, while smaller, still offers impressive performance with 100 watts per channel into 8 ohms. This versatility means both amplifiers can accommodate a variety of audio setups, whether in a home theater or a high-fidelity stereo system.

The SST series incorporates Bryston’s proprietary amplifier technology known as “Squared” which allows for class A performance with an overall class AB operation. This design minimizes distortion and provides a warm, natural sound. Alongside this, the amplifiers feature a highly efficient, low-noise toroidal power transformer that contributes to their impressive transient response, allowing music to play with precision.

Another standout characteristic is the build quality. Both the 4B SST and 3B SST are constructed using a sturdy 17-inch faceplate made from aluminum, designed to withstand the rigors of both studio and home environments. The amplifiers also feature a uniquely designed heat-sink system that keeps temperatures in check during heavy operations, ensuring optimal performance without overheating.

Bryston amplifiers also boast a long lifespan, backed by a 20-year warranty on their products, which speaks volumes about their reliability and customer confidence. They include fully balanced input circuitry, allowing for low noise pickup and signal integrity over long cable runs.

Furthermore, the 4B SST and 3B SST are equipped with user-friendly features like RCA and XLR connections for flexible integration into a range of audio systems. With their transparent sound reproduction, high power output, and robust construction, the Bryston 4B SST and 3B SST amplifiers continue to be the preferred choice among audio enthusiasts and professionals alike. Their enduring legacy is rooted in their commitment to superior sound quality and long-lasting performance.
