The B-52 US-1200 Power Amp has low noise, low distortion circuitry, and high current output stages. B-52 uses oversized toroidial transformers and large filter capacitors to deliver super-clean, fist-pumping output even when driving 2-ohm speaker loads. The stellar looking US-Series professional power amplifiers are made to outperform in any setting. B-52 US-series power amplifiers use the most reliable linear output devices, which provide ultralow distortion and ruler-flat frequency response. Backed by a 3-year warranty.

With our Guaranteed Lowest Price, you can be assured of complete satisfaction and the lowest available price, or your money back!

B-52 US-1200 Power Amp Features:

Compact 2-rack sizeHigh-current toroidal transformers for greater 2-ohm power21-position detent gain control knobs for consistent settingsFront panel LED display: Power, bridge and parallel LEDs and signal,20dB, -10dB, 0dB, clip and protect LEDs for each channelProtection: short circuit, output current limiting, thermal, DC offset, turn on/off muting, RF protection and circuit breakerClip limiters reduce distortion without sacrificing peak performance (defeatable on US-3000/US-4000)Sub-sonic filters protect speakers and increase headroom (defeatable)Balanced combo XLR and ¼" TRS input connectors and link XLR output connectors5-Way binding post and Speakon™ outputsLow-noise cooling fans with continuously variable speed and highly efficient front-to-rear forced air keeps the amplifiers cool
