        B-52

        Designed to provide outstanding performance on any stage, in the clubs, and on the road.

        The B-52 US-1800 Power Amplifier features low noise, low distortion circuitry and high current output stages. It uses oversized toroidial transformers and large filter capacitors to deliver super clean, fist pumping output even when driving 2-ohm speaker loads.

        All B-52 US-series power amplifiers use the most reliable linear output devices for ultralow distortion and ruler flat frequency response. The stellar looking B-52 US-Series professional power amplifiers are made to outperform in any setting. 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.
