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.
B-52 US-4000 Power Amplifier
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

bought this amp 5 weeks ago to power my lx-18 b-52 subs.does the job with easy,bass is tight and very accurate,very clean sound,and fans are quiet.front blue leds lights are easy to see at night.also have a pair of plye pro 21" subs,which i built in a 5 cubic foot box vented by 2- 4" flare tuned ports,tuned at 34hz.hooked up the us-4000 amp pushed them with no problem,also have a pair of selenium 18" subs rated at 1100 watts rms 2200 max,which are in 2 lx-18 boxes.hooked them to us-4000 pushed them with easy.this amp is very powerful and clean sounding,also hooked it to my selenium mid,highs sound was open,and soundstage was outstanding.I wound recomend this amp to any who high power with clean sound.equiment used preamp-adcom gtp 550,2-audiocontrol c-131,31 band eqs,2-dbx-223xl crossovers,marantz-cd-67se cd player 2-us-4000 power amps,2-rotel rb-1080 amps.speaker 2-b-52 lx18,2- selenium sws1100 subs,[in lx 18 boxes],4-selenium 300 watt 50 oz magnet horn drivers,4-selenium 15" 800 watt pw5 mids
