It is sold as a single unit, so a stereo system takes two. This is the amplifier Bryston builds when current delivery matters more than chassis count.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eEffortless with any load.\u003c\/b\u003e 1000W into 8Ω doubling to 1800W into 4Ω shows a power supply that holds its voltage under load, which is what keeps bass tight when the music gets busy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eGrip on the drivers.\u003c\/b\u003e A damping factor above 500 at 20Hz into 8Ω means the amplifier keeps firm control of large bass drivers rather than letting them overhang.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQuiet in every sense.\u003c\/b\u003e Convection cooling means no fan noise, and a signal to noise ratio of -117dB balanced leaves the background properly black between notes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eUnder the Hood\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eQuad complementary output topology paired with the patented Cubed input stage and Salomie circuit, cancelling distortion at the input rather than correcting it later.\u003c\/li\u003e\n\u003cli\u003eBalanced XLR (pin 2 positive) and unbalanced RCA inputs, 29dB gain, 3.16V sensitivity for full output, input impedance 5kΩ unbalanced and 5kΩ per leg balanced.\u003c\/li\u003e\n\u003cli\u003eSlew rate above 120V per microsecond, THD below 0.005% at rated power from 20Hz to 20kHz, with SoftStart turn-on and a 5V to 12V AC or DC trigger input.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eCHT Insider Verdict\u003c\/h3\u003e\n\u003cp\u003eThe 28B³ is aimed at large rooms and speakers that punish ordinary amplifiers. What you get for the money is not just volume, it is composure, the sense that nothing is being asked to work hard. It is heavy, it draws real power at idle, and you need two of them, so plan the rack and the power circuit before it arrives.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePro Tip:\u003c\/b\u003e These run warm even without a signal, so give each chassis breathing room above and to the sides.
