Need help?Do you have a question about the Bryston OBSOLETE 3B-NRB and is the answer not in the manual?
Bryston's 3B stereo power amplifier has two modules, operable independently or combined for 400W mono operation.
The 3B requires direct wall connection due to massive power supplies drawing high current; avoid preamps or power bars.
Three-color LEDs indicate power status and signal distortion thresholds, with red signaling overload requiring immediate attention.
Amplifier can drive speakers to full potential; clipped signals can cause damage, especially to tweeters. Consider speaker fuses.
Mono mode combines two sections for increased output voltage, producing over 400W into 8 ohms; uses only the left channel input.
Features unbalanced RCA/phono and balanced XLR/1/4" phone jacks with a switch for selecting input type.
Equipped with four gold-plated binding posts accepting banana plugs or bare wire for speaker connections.
Recommends low inductance speaker cables for minimal signal loss between the amplifier and speakers.
A ground lift switch can eliminate hum caused by ground loops in specific multi-amplifier or wiring setups.
Illustrates connection methods for dual (stereo) operation (120W/80) and mono (bridged) operation (400W/80 min.).
Details on rear panel controls for selecting input types (balanced/non-balanced) and output modes (DUAL/MONO).
Twenty-year limited warranty covering manufacturing defects for original and subsequent owners, starting from purchase date.
Service is available through Bryston dealers or direct contact in Canada and the United States.
Warranty is voided by damage from abuse, tampering, or failure to follow operating instructions.
