B52 US1200 | US-SERIES PROFESSIONAL POWER AMPLIFIERS An overdue and welcomed addition to the B-52 product line is the US-Series of professional power amplifiers. We took our time to design these stellar looking amps to outperform the competition on stage, in the clubs and on the road. To obtain studio quality audio reproduction we used oversized high current toroidial transformers and large filter capacitors to deliver super clean, fist pumping output even when driving a 2 ohm speaker load. NICE RACK!
B-52 believes in overbuilding all of our products and the US-Series is no exception. These amplifiers use the most reliable linear output devices which provide ultra low distortion and ruler flat frequency response. The US-Series is backed by our rock solid 3 year warranty and B-52’s commitment to reliability that is known the world over. Like all B-52 products the US-Series amps are built to perform in the most rigorous conditions. KpoDJ recommended! US Series Professional Power Amplifiers are loaded with features • Compact size - up to 3200 watts in 2 rack spaces
• 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 1/4" 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 cooling design keep amplifiers cool | Model | US-1200 | US-1800 | US-3000 | US-4000 | | Rated Output Power | << Stereo Both Channel Driven >> | | 8 Ohms | 200 watts | 300 watts | 500 watts | 700 watts | | 4 Ohms | 300 watts | 450 watts | 750 watts | 1100 watts | | 2 Ohms | 430 watts | 750 watts | 1200 watts | 1600 watts | | Rated Output Power | << Bridged Mono >> | | 8 Ohms | 600 watts | 900 watts | 1500 watts | 2200 watts | | 4 Ohms | 850 watts | 1400 watts | 2400 watts | 3200 watts | | Input Sensitivity | 1.23 (+4 dBu) for full power @ 4 Ohms | | Input Impedance | 30 kohms Balanced/15 kohms Unbalanced | | Input CMRR (1 kHz) | Better than 60dB | | Frequency Response | 0/-0.5dB: 20Hz - 20kHz <<I>> 0/-3dB: 5Hz - 60kHz | | Signal to Noise Ratio
