Designed to provide outstanding performance on any stage, in the clubs, and on the road.
The B-52 US-4000 Power Amplifier features low noise, low distortion circuitry and high current output stages. B-52 uses oversized toroidal transformers and large filter capacitors to deliver super clean, fist pumping output even when driving a 2-ohm speaker load.
All B-52 US-series power amplifiers use the most reliable linear output devices to provide ultra-low 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.
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.
