OUR MISSION

To design a state of the art 1000 watt power amplifier that does not compromise performance at 1/10th power. A significant part of the design criteria for the 28B SST2 was to develop a very powerful amplifier that would drive any speaker on the planet but maintain an ideal power curve at 1 watt as well as at 1000 watts and every power level in between. Most amplifiers exhibit a power curve whereby the best noise floor, drive capability and distortion is maintained from about 1/3 power and up. The Bryston 28B-SST2 Mono amplifier maintains its power curve right from the first watt. This results in a BIG POWERFUL amplifier that sounds incredibly detailed and musical at very low levels and maintains that same sophistication and drive capability with even the most difficult, inefficient speakers, large or small. The Bryston 28B-SST2 is a fully balanced output amplifier (BRIDGED), which has reduced THD and IMD to unprecedented low values, (typically 0.001% or less), for a new degree of transparency, musicality and ease of listening. Superbly low noise floor, typically below – 115dB, yields an inky black silence between notes for hauntingly realistic reproduction. Tremendous power reserves give the 28BSST2 virtually perfect freedom from overload on any type of speaker or music, bringing the performance and realism directly into your listening environment. The 28B’s ability to resolve subtle musical details has to be heard to be believed – it truly sets a new standard : Mission accomplished.

FEATURES

• Selectable input – balanced (xlr) or single ended (rca)

• Selectable gain – 1v = 29db or 2v = 23dB

• External power on off control – 12v trigger

• New micro controlled soft start

• New power switch

• All A/C is totally shielded from Audio circuits

• Maintains exceptionally low noise and distortion

from very low to very high power demands

HEAT SINkS

The Bryston 28B-SST2 employs a total new computer modeled heat sink design maximizing heat dissipation for long-term “fan-free” operation into the most demanding speaker loads.

POWER SUPPLy

The Bryston 28B-SST2 is a single channel mono block power amplifier capable of delivering over 1000+ watts of power. To provide this power the 28B POWER SUPPLY utilizes a 2000 VA custom power transformer, with 120,000 uf of filter capacitance, supply rails of +/- 90v. The component layout has been optimized so power path lengths are very short, and all wire has been eliminated after the power transformer.

DESIGN PHILOSOPHY ENSURES SONIC-SUPERIORITY

• All analog signals are delivered by fully discrete components.

• All critical transistors are closely matched.

• All capacitors are selected for long life.

• All audio connectors are gold plated, to be trouble free.

THE CONSEQUENCE

Obviously the goal of all this technology is to transport you to

the scene of the movie or the location of the musical recording.

Experiencing all the drama, movement and emotions intended

is the one and only true measure of any audio/video system. We

know you will agree the Bryston 28B-SST² Mono Amplifier

provides you with an open window on the musical experience.

If your requirements are for sonic excellence in both analog

and digital formats without compromises in performance,

value and reliability look no further than the Bryston

28B-SST² Mono Amplifier.
