QSC RMX 4050HD 4000W Power Amplifier for sale in Riverdale, MD
QSC's RMX 4050HD power amplifier represents the state-of-the-art in professional quality performance at an affordable price. Perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians, and mobile DJs, the RMX 4050HD is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven reliability.Like its smaller sibling (the RMX 1850HD), the RMX 4050HD is one of two RMX "Heavy Duty" models designed to work as hard into 2 ohm loads as most competing amplifiers will at 4 ohms. With a three-tier, Class H design, the RMX 4050HD is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. The 120 volt versions of the RMX 4050HD accomplish all this with a standard 15 amp plug.Like all RMX amps, the RMX 4050HD features balanced 1/4" TRS, XLR and barrier strip inputs, binding posts and Neutrik SpeakonŽ outputs, front-mounted gain controls, plus signal and clip LED indicators to monitor performance. General Features: The RMX 4050HD provides improved thermal performance that gives you higher continuous power in 2 ohms stereo or 4 ohms bridged applications Dual mono, high current power supply for increased reliability and performance 3RU chassis only 16" deep Professional quality performance - incorporates road-proven QSC designs High-current toroidal transformers for greater 2 ohm power and low noise Independent user-defeatable clip limiters reduce distortion Selectable low frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom Balanced 1/4" (6.3 mm) TRS, XLR and barrier strip inputs Binding post and Neutrik Speakon outputs Front mounted gain controls for easy access Signal and Clip LED indicators to monitor performance 3-year Manufacturer's warranty SPECIFICATIONS RMX 4050HD RMX 4050HD / CE Compliant STEREO MODE (Both Channels Driven) 8 ohms FTC 20 Hz - 20 kHz, 0.1% THD EIA 1 kHz, 0.1% THD 800 W850 w 650 W 4 ohms FTC 20 Hz - 20 kHz, 0.1% THD EIA 1 kHz, 0.1% THD 1300 W1400 w 1300 W 2 ohms FTC 20 Hz-20 kHz 0.1% THD EIA 1 kHz 1% THD 1600 W2000 w 1600 W2000W BRIDGE MONO MODE 8 ohms FTC 20 Hz-20 kHz 0.1% THD EIA 1 kHz 0.1% THD 2600 W2800 w 2600 W2800 w 4 ohms EIA 1 kHz 1% THD 4000 W 4000W Distortion (SMPTE-IM) Less than 0.02% Distortion (Typical)20 Hz-20 kHz: 10 dB below rated power1 kHz and below: full rated power Less than 0.02% @ 4 ohms, less than 0.01% @ 8 ohmsLess than 0.02% @ 4 ohms, less than 0.01% @ 8 ohms Frequency Response 20 Hz to 20 kHz, 8 ohms, LF filter bypassed, +0/-1 dB5 Hz to 50 kHz, 8 ohms, LF filter bypassed, +0/-3 dB Damping Factor Greater than 250 @ 8 ohms Noise (unweighted) 100 dB below rated output (20 Hz - 20 kHz, 8 ohm load) Input Impedance 20k ohm balanced, 10k ohm unbalanced Input Sensitivity 1.25 Vrms for 800 W into 8 ohms 1.12 Vrms for 650 W into 8 ohms Voltage Gain 64x (36 dB) for 8 ohm load Controls Front:Controls Rear: AC power switch, Ch. 1 and Ch. 2 gain control10-pole DIP switch featuring LF filter on/off, LF filter 30/50 Hz, Clip Limiter on/off controls for each channel and switches for selecting Stereo, Parallel, or Bridge mode.
