The 28B-SST is a powerhouse balanced mono amplifier providing a minimum of 1000-watts at 8-ohms.
A significant part of the design criteria for the 28B SST 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-SST
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-SST 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 28B-SST 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-SST 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-SST 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.
