3Bsst & 4Bsst POWER 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 figure at right. 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. 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.

OPERATION

BRIDGED MODE

Bridged mode” refers to the com- bining or “bridging” of two ampli-

fier channels into a single ampli- fier channel. The primary reason

for doing this is to achieve a sin-

gle amplifier channel with much

greater output power. When two

3B channels or two 4B chan-

nels are bridged, the combined

single channel will output up to 2

times the voltage and therefore,

theoretically, 4 times the power

of a single non-bridged chan- nel. In practice, the actual output

power achieved is limited by the

capability of the power supply as

well as the ability of the amplifier to dissipate the increased heat that is generated. It should also

be noted that the load connected to a pair of bridged 3B or 4B channels should be 8 ohms or greater.

•Only one input is used: the LEFT channel (sometimes referred to as channel #1).

•The single input can be either balanced or un-balanced.

•The two BLACK binding post outputs are NOT used. Only the two RED binding post connectors are used. The LEFT (Ch. 1) binding post is the positive polarity connector and the RIGHT (Ch. 2) RED binding post connector is negative.

•The bridged output is floating or un-grounded. DO NOT CONNECT EITHER OUTPUT TERMINAL TO GROUND.

•To engage bridged mode, put the MODE switch, located on the rear panel, into the BRIDGED position, but. before do- ing so make sure all input and output connections are correct for bridged mode operation.

3BSST, 4BSST specifications

The Bryston 4BSST and 3BSST are exceptional power amplifiers that embody the premium quality and performance standards synonymous with the Bryston brand. Renowned for their robust build and superior audio fidelity, these amplifiers are designed for both audiophiles and professionals who demand excellence in sound reproduction.

The Bryston 4BSST is a higher-powered model capable of delivering 300 watts per channel at 8 ohms and easily transitioning to 500 watts per channel at 4 ohms. This amplifier is perfect for driving larger speakers and creating a more dynamic listening experience. The 3BSST, on the other hand, provides a slightly more reserved output of 150 watts per channel at 8 ohms and 250 watts at 4 ohms, making it an excellent choice for smaller systems without compromising on sonic clarity.

One of the key features of both models is the SST (Special Serial Technology) Mosfet output stage, allowing for rapid response times and low distortion rates. This technology ensures that the audio signal remains clean and clear, even at high volumes. The amplifiers employ an innovative parallel push-pull output design, which not only bolsters dynamic range but also enhances the overall soundstage.

In terms of construction, Bryston amplifiers are built to last. The chassis is made from heavy-gauge steel with a baked enamel finish that not only provides a sleek and professional appearance but also contributes to overall durability. Moreover, the 4BSST and 3BSST feature a unique thermal management system that uses extensive heat sinks to maintain optimal operating temperatures, thus ensuring reliability during prolonged use.

Another significant characteristic of both amplifiers is their low noise floor. This trait is particularly important for high-resolution audio systems, as it allows for more subtle details to come through, providing an immersive listening experience. They also include Bryston’s signature 20-year warranty, reflecting the company’s commitment to quality and customer satisfaction.

For connectivity, both models provide balanced XLR and unbalanced RCA inputs, accommodating a variety of audio sources and setups. Their simple, clean interfaces make them user-friendly while still providing the performance flexibility that seasoned audio enthusiasts seek.

In summary, the Bryston 4BSST and 3BSST amplifiers exemplify the pinnacle of audio engineering, showcasing an unmatched blend of power, clarity, and durability. Whether you are setting up a high-end home theater system or a professional studio, these amplifiers are equipped to deliver exceptional sound quality for years to come.
