QSC RMX1450 Power Amplifier 700 Watts
Limited Offer: 6-Year Warranty The best warranty promotion in the business has been extended. All PLX, RMX, or PL2 model amplifiers purchased now through December 31, 2005, will receive QSC's 6-Year Full Factory Warranty... FREE! Simply register the purchase online at www.qscaudio.com. The best professional warranty. Muscular Power Plant: The power supply is the heart of an amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The RMX uses a powerful high-current toroidal transformer and ample filter capacitance to ensure generous energy reserves. This makes a critical difference in sound quality, allowing the amp to effortlessly punch out high level transients, even when driving abusive 2-ohm speaker loads. Superior Performance RMX amplifiers deliver true studio-quality sound. A full complementary output circuit using the highest-grade linear output devices delivers ultra-low distortion (<0.05% THD) and a ruler-flat frequency response. SMT (Surface Mount Technology) triples small-signal component density, enabling us to pack up to 2400 watts of power in a chassis only 2 rack spaces and less than 16" deep. And unlike other designs, RMX output devices are direct-mounted to the heat sink for optimum thermal coupling and cooling. RMX1450 Power Amplifier 700 Watts Features• Independent defeatable clip limiters reduce distortion without sacrificing peak performance.• Selectable low-frequency filters boost system response, protect speakers, and ensure low-end tightness by more precisely matching the amplifier's range to the loudspeakers. • Barrier strip, XLR, and 1/4" balanced inputs plus Speakon and binding post outputs provide easy connections. • Low-noise variable speed fans with rear-to-front air flow keep amplifiers and racks cool.Technical Description • Stereo Mode (EIA: both channels driven) • 8 ohms EIA 1 kHz 0.1% THD: 280W • 4 ohms EIA 1 kHz 0.1% THD: 450W • 2 ohms EIA 1 kHz 1% THD: 700W • Bridge Mono Mode • 8 ohms EIA 1 kHz 0.1% THD: 900W • 4 ohms EIA 1 kHz 1% THD: 1400W • Signal to Noise (20 Hz-20 kHz): 100dB • Distortion (SMPTE-IM): Less than 0.01% • Input Sensitivity @ 8 ohms: 1.12v (+3.4 dBu) • Voltage Gain: 40x (32 dB) • Output Circuitry: AB • Current Consumption (1/8 power pink noise at 4 ohms @ 120VAC,both channels driven; multiply current by .5 for 230V units.): 7A • Distortion (typical): 20 Hz-20 kHz: 10 dB below rated power: Less than 0.03% THD 4 and 8 ohms • 1.0 kHz and below: full rated power: Less than 0.03% THD 4 and 8 ohms • Frequency Response: 20 Hz-20 kHz, ± 0/-1 dB, -3 dB points: 5 Hz-50 kHz • Damping Factor (1 kHz and below): greater than 300 at 8 ohms • Input Impedance: 10 K ohms unbalanced, 20 K ohms balanced • Input Clipping: 10 Vrms (+22dBu) • Cooling: Continuously variable speed fan, rear-to-front air flow • Connectors (each channel): Input: Active balanced; barrier strip, XLR,and 1/4" (6.3 mm).
