Know before you buy
The modular design means each of the five channels has its own independent power supply. This isolation prevents interference between channels, ensuring that a demanding scene in one speaker doesn't impact the performance or clarity of the others.
Yes, the 9B SST2 features bridgeable channels. This allows you to combine two channels into one for significantly higher power output if you have particularly demanding speakers that require more headroom.
Balanced (XLR) inputs are ideal for longer cable runs or environments with potential electrical noise, as they reject interference. Single-ended (RCA) inputs provide standard compatibility with most consumer pre-amplifiers and receivers.
Yes, the unit is designed to be rack-mountable. Given its weight of 76 pounds, ensure your rack system is rated to support the load and provides adequate ventilation for the amplifier.
Bryston’s legendary 20-year warranty is transferable and covers the amplifier against defects in materials and workmanship. It is a testament to the build quality and the company's confidence in the longevity of their hand-built components.
With 140 Watts RMS per channel into 8 Ohms, this amplifier is robust enough to drive most high-end home theater speakers with ease. If you are using low-impedance or inefficient speakers, the power output increases to 200 Watts into 4 Ohms, providing plenty of dynamic headroom.
