Meet the 9B Cubed Multi-Channel Amplifier
Taking your Multi-Channel applications to New Heights
Bryston's 9B is a legendary line of multi-channel amplifiers. This new Cubed iteration lifts the performance of theatres and other multi-channel applications to new heights far beyond expectations set by inferior options.
The Bryston 9B Cubed Multi-Channel Amplifier provides premium grade multi-channel amplification for exceptional power, clarity and control for immersive home cinema and high-performance surround sound systems.
Now with each channel capable of 200 watts, more speakers than ever before can be driven with ease. Unlike most multi-channel amplifiers and receivers, the all new 9B Cubed features up to 5 self contained channels. Since each has a fully independent power supply, high output on one channel won't be a drag on the others, so every note will be dynamic and clear.
Network monitoring and control is built into every unit to make integration with home automation systems easy. Keep tabs on the temperature, see overdriving warnings, and even mute individual channels all from the amp's own webpage.
Best of all, the new 9B Cubed brings Bryston's patented Salomie circuit to a 5 channel form factor for the first time. Finally, you can have a multi-channel amplifier that sounds as great as other Bryston amps.
Brystons Cube Series
At Bryston, finding ways to eliminate distortion from of their designs is a way of life. All Cubed Series electronics feature a new patented input circuit precisely optimised and linear beyond any they’ve used before. Featuring twelve active devices in a groundbreaking array, this new circuit both matches the amplifier to virtually any preamplifier and provides the first 6dB of gain.
The new input stage is so transparent, its measurable distortion is less than 1/1000th of 1 percent! Newly designed circuitry in the Cubed Series amplifiers is virtually impervious to noise such as RFI and others induced by external and environmental causes. Bryston's patented Salomie Circuit feature a unique method of trapping distortion components in the main signal path that pass through other amplifiers only to be amplified and played by your loudspeakers. This innovative distortion reduction method results in a much more natural and nuanced rendition of your recordings—playback more true to the original recordings and more enjoyable to your ears.
Quad-Complementary topology improves linearity to a new standard of accuracy while virtually eliminating aggressive higher harmonic distortion byproducts. Quad Complementary eliminates crossover distortion by improving transistor matching and reduces capacitance in the output stage by a factor of four which improves transient response and bandwidth. The overall harmonic distribution of Bryston’s Quad-Complementary output mimics the characteristics of a class-A design but with dramatically lower distortion. Each amplifier channel includes its own fully independent power supply with separate transformer; a feature uncommon even in amplifiers far more expensive.
Bryston engineers strive for accuracy and transparency because that is what sounds best. When a playback system is faithful to the recording, the listener can enjoy the most subtle details, capturing the depth and soul of the performance as the artist intended.
