Designed to provide outstanding performance on any stage.

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.

  • Compact 2-rack size
  • High-current toroidal transformers for greater 2-ohm power
  • 21-position detent gain control knobs for consistent settings
  • Front panel LED display: Power, bridge and parallel LEDs and signal,
  • 20dB, -10dB, 0dB, clip and protect LEDs for each channel
  • Protection: short circuit, output current limiting, thermal, DC offset, turn on/off muting, RF protection and circuit breaker
  • Clip 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 connectors
  • 5-Way binding post and Speakon„¢ outputs
  • Low-noise cooling fans with continuously variable speed and highly efficient front-to-rear forced air keeps the amplifiers cool

Get the super-clean power you need for any gig.
