Designed to provide outstanding performance.
 The B-52 US-3000 Power Amplifier features low-noise, low-distortion circuitry and high-current output stages, toroidal transformers, and large filter capacitors to deliver super-clean, fist-pumping output even when driving 2-ohm speaker loads. Its highly reliable linear output devices provide ultra-low distortion and ruler flat frequency response. Backed by a 3-year warranty.
 Features
 - 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.
