Radical Design Innovation
Multi-Channel Sound:

For the finest home theater and surround sound music systems, requiring multiple channels of superb sound, Bryston's 9B THX five-channel modular amplifier provides you with an extremely versatile and flexible source of power. The 9B THX is the ideal choice for an audiophile-quality surround installation where high power for the two fronts, one center channel and two rear channels is desired.

The Bryston 9B THX is a hand-crafted, modular, single-chassis 5-channel power amplifier delivering 120 watts per channel at 8 Ohms, and 200 watts at 4 Ohms. Each Modular channel contains all the electronic circuitry connections and independent power supply, necessary to deliver the best possible sonic quality. The chassis simply supplies AC and five power LED's on the front panel indicating each channel's functional status, (green for power-on, red for overdrive). A 17-inch faceplate version without handles is also available.

New Standards of Accuracy:
The Bryston THX amplifiers incorporate the use of an innovative gain stage topology, which yields the quietest possible noise floor through the use of low-impedance pathways within the amplifier. This approach also has strong advantages in improving 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. The 9B THX amplifier uses Bryston's proprietary Quad-Complementary output section, which improves linearity to a new standard of accuracy, while virtually eliminating aggressive higher harmonic distortion products. These power supplies employ multiple filter capacitors per channel, rather than a single pair of larger filter cans. This improves 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 balanced inputs can be switched to allow normal gain (23 dB) or high gain (29 dB). The RCA inputs have a gain of 29 dB. From input to output, all the circuitry in the 9B THX has been optimized for the most accurate performance and flexibility possible.

5 Modular Channels
Independent Power Supplies:


Exclusive to Bryston among 5-channel amplifiers, independent (one per channel) toroidal-transformer power supplies provide precise and focused sound-staging. Bryston's research has shown that all amplifiers require separate power supplies per channel for the best imaging, clarity and dynamic range, especially crucial given today's and tomorrow's most demanding digital sound sources.

The Lucasfilm Home THX certification parameters are easily met for their intended use within a multi-channel audio/video installation. The 9B THX amplifier comes standard with a rear panel, 4 to 12 volt (A/C or D/C), power on/off trigger function to allow remote turn-on from your processor.

Unique Burn-In Procedure:

Each and every Bryston amplifier undergoes a very extensive "burn-in" procedure. Following a complete operational checkout, every amplifier is placed on a test-bench and run for 100 hours at full output (one-hour on/one-hour off for additional thermal stress), with a high frequency squarewave input and a capacitive load. This extremely rigorous burn-in quickly "matures" components and weeds out any potential premature failures. The result is reliable trouble-free performance for many years, and is backed by Bryston's exclusive 20 year full warranty.

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 9B THX amplifier provides you with an open window on your listening experience.
