This is a Bryston 4B stereo amplifier. This model is aimed at the pro-audio market, but it's also terrific for home use. Bryston is one of those rare amplifier companies who's products are respected equally in both high end and professional audio industries. This is a fantastic freakin' stereo amplifier for this price, PERIOD. The amp has some nicks and scratches, but it's customary wear and tear for a component of this vintage.
This amplifier is out of warranty - Bryston actually offers a 20-year warranty on their products, which is another rarity! A company that stands by their products for 20 years, imagine that! Almost all their amps last FAR longer of course, and are easily serviceable.
This amp is for local pick-up only
This is a STEAL. We own two that we're never selling!
So scoop this up.
Tech Specs:
TECHNICAL SPECIFICATIONS:
Solid-state stereo power amplifier. Output power: 250W continuous into 8 ohms (24dBW), 400Wpc rms continuous into 4 ohms (23dBW); 800W continuous into 8 ohms in bridged mode (29dBW). Current delivery: 16A continuous, 48A peak, per channel. Frequency response: 1Hz-100kHz, ±3dB for 1W output. S/N Ratio: hum and noise, 108dB below rated output, 90dB IHF. Input sensitivity: 1.4V for 250Wpc into 8 ohms. Voltage gain: 30dB. THD+noise: 20Hz-20kHz, 0.01%. IM distortion (60Hz+7kHz, 4:1, SMPTE method): less than 0.01% at rated power. Damping factor: greater than 500 at 20Hz, at 8 ohms (equivalent to an output impedance of less than 0.016 ohms). Input impedance: 50k ohms unbalanced, 30k ohms balanced. Polarity: non-inverting.
