Bryston's Model 10B Electronic Crossover combines ideal signal-handling with an enormously flexible control function.Simple, direct front-panel switches allow any crossover curve to be setinstantly, and the signal purity is always maintained.<p>The Model 10B features independentlyselectable crossover points for high-pass and low-pass, in case the speakerinstallation requires slightly overlapped, (or slightly staggered), responsecurves for the drivers. You can also independently select crossover slope,from 6, 12, or 18dB/Oct., where one driver requires faster cutoff thananother in the same system. A fixed frequency plug in Linkwitz-Riley alignmentwith steep rolloff curves of 24 dB/Oct. is also available.<p>The crossover may be used in any ofthree internal connections: 2-way stereo, 3-way mono, and a special configuration,2-way stereo with summed low pass out to allow the use of one sub-woofer.The 10B is available in two stock versions, a 10B sub incorporating frequenciesmore suitable to sub-woofer applications and a JOB standard which is moreapplicable to speakers requiring frequency control in the midband and tweeterareas.<p>All crossover selections are extremelyaccurate and repeatable, being implemented with 1% selected metal-filmresistors and polystyrene capacitors. All switches are heavily gold-plated,for lifetime protection from corrosion. The level controls are precise1 dB increments, also derived from gold-plated switches and 1% metal-filmresistors. Most important, however, is that the Bryston 10B Crossover usesNO integrated circuits in the signal path. All internal buffer and amplificationstages are Bryston's exceedingly linear and superbly quiet discrete op-ampcircuitry. This means the signal is always maintained as "Audiophile Quality",with stability and freedom from noise and distortion unapproached in othercrossovers.<p>From the point of view of adaptability,flexibility and signal integrity, the Bryston 10B Electronic Crossoveris the ideal choice for the widest range of multi-way speaker installations.

Learn more <B>Bryston SST Series Amplifiers:</B> <P>Bryston has a continuing commitment to design and manufacture the most accurate and reliable audio products available. We maintain an extensive research and development division, which is constantly looking for methods to improve the performance, value and reliability of our amplifiers. The Bryston SST Series of amplifiers is the direct result of this continuing quest for perfection. These amplifiers represent a significant step forward in the art and science of audio amplification. Among the advances included in this new SST Series are: Faster, more linear and more reliable output transistors for better high frequency accuracy; doubled filter capacitance for even deeper and better-controlled bass; a new proprietary grounding protocol which eliminates the need for ground-lift switches and reduces system noise; new computer-modeled heatsink profile for cooler operation and longer component life. Sound quality is improved to a stunning degree. Reviewers agree, this new product line sets a higher standard for musical accuracy than ever before possible. <P><B>Design Philosophy Ensures Sonic Superiority:</B></B. <p> <BR><BR>All analog signal circuitry is fully discrete to avoid the compromises, phase shift and non-linearity inherent in IC's. The Bryston SST Series amplifiers incorporate the use of an innovative gain stage topology, which yields a substantially lower noise floor through the use of low-impedance pathways within the amplifier. This same approach also has strong advantages in reducing the overall distortion performance. Bryston's computer controlled distortion analyzers confirm Intermodulation Distortion levels less than 10 parts per million (below 0.0009%) are typical for this new circuitry. All SST amplifiers use Bryston's proprietary Quad-Complementary output section, which improves linearity to a new standard of accuracy, while virtually eliminating aggressive higher harmonic distortion products. From input to output, all the circuitry in the SST series of amps has been optimized for the most accurate performance possible. Custom totally independent and separate torodial power supplies for each channel of amplification provides precise and focused soundstaging. The power supplies employ multiple filter capacitors per channel, rather than single pairs of larger filter cans. This allows improved high frequency response and reduces overall losses in the supply. Gold-plated balanced or single-ended (RCA) input connectors are standard as well as gold-plated 5-way loudspeaker binding posts, to eliminate possible causes of distortion from corrosion. A rear panel switch allows for the use of Balanced inputs (XLR or 1/4" phone jack) or unbalanced inputs (RCA). The inputs can be switched to allow different gain settings.

Learn more 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. <BR><BR>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. <BR><BR>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.
