9B ST Specifications Bryston Five-Channel Amplifier

The Bryston 9B-ST is a superior quality, 5 channel power amplifier delivering 120 watts of power at 8 Ohms, and 200 watts at 4 Ohms. The 9B-ST is basically a five channel version of our very popular 3B-ST stereo amplifier but intended for use in applications where compactness, versatility and expandability are of prime importance.

Each modular channel contains all the electronic circuitry, connections and independent power supply. The chassis simply provides AC to each channel and a separate power LED illuminates on the front panel indicating individual channel power status.

Dimensions are: (WHL) 19 x 5.25 x 16 Inches | 4.25 x 13.33 x 42 cm. | Weight 75 lbs, 34 Kg.
17 inch version also available.

VERSATILE FEATURES:

• Five channels in a single compact chassis.
• Modular construction for quick and easy repairs.
• Balanced or unbalanced operation at the flick of a switch.
• Gold plated custom 5-way banana jacks, RCA and XLR connectors.
• Totally separate and independent power supplies for each channel.
• Remote 12 volt trigger. (THX version)
• THX certified.
