Description

The Bryston 9B-4 is the four-channel configuration of the 9B Cubed power amplifier, designed for home theatres and multi-channel audio systems. Each channel delivers 200 watts into 8 ohms or 300 watts into 4 ohms and includes an independent power supply and toroidal transformer. This self-contained design keeps the power demands of one channel from drawing on the supply of another, supporting clear, dynamic playback across the system.

The modular construction allows a fifth channel to be added as your system grows. Bryston’s patented Salomie circuit, balanced and unbalanced inputs, and selectable gain provide flexible system integration. A built-in web interface supports remote control and monitoring, including individual channel muting, while fanless convection cooling keeps operation quiet. DC trigger control and a microprocessor-controlled SoftStart sequence simplify automated power management.

Features

Four Independent Amplifier Channels
Each channel features a dedicated power supply and toroidal transformer for independent power delivery.

Expandable Modular Design
The four-channel configuration can accommodate an additional channel module, expanding the amplifier to five channels.

Patented Salomie Circuit
Features Bryston’s patented amplifier circuit used throughout the Cubed Series.

Network Control and Monitoring
Use a web-enabled device to control power, monitor temperature and clipping, mute individual channels and access firmware updates.

Balanced and Unbalanced Inputs
XLR and RCA inputs accommodate connections from compatible preamplifiers and surround processors.

Selectable Gain
Two gain settings allow the amplifier to be matched to the connected audio system.

Fanless Convection Cooling
Passive cooling dissipates heat without adding fan noise to the listening environment.

SoftStart Power-Up
A microprocessor-controlled startup sequence helps prevent circuit breakers from tripping during power-up.

DC Trigger Control
Supports automated turn-on and turn-off with compatible system components.

Machined Aluminum Construction
The enclosure and dress panel feature machined and anodized aluminum construction.
