| RMX850, 830 Watt 2 Channel Amplifier RMX850, 830 Watt 2 Channel Amplifier (Power Amps) |
 | Comprehensive Features: The RMX Series is packed full of professional features that increase performance and flexibility: The RMX 1850HD provides improved thermal performance that gives you higher continuous power in 2 ohms stereo or 4 ohms bridged applications (a RMX 1850HD exclusive!) 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 1/4in 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 coolGeneral Features: Compact size - up to 2400 watts in 2 rack spaces Professional quality performance - incorporates road-proven QSC designs High-current toroidal transformers for greater two-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 1/4in (6.3mm) 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 Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers 3-year Manufacturer's warranty SPECIFICATIONS RMX 850 RMX 1450 RMX 1850HD RMX 2450 STEREO MODE (Both Channels Driven) 8 ohms FTC 20 Hz - 20 kHz, 0.1% THD EIA 1 kHz, 0.1% THD 185 W 200 W 260 W 280 W 350 W 360 W 450 W 500 W 4 ohms FTC 20 Hz - 20 kHz, 0.1% THD EIA 1 kHz, 0.1% THD 280 W 300 W 400 W 450 W 550 W 600 W 650 W 750 W 2 ohms EIA 1 kHz, 1% THD 430 W 700 W 900 W 1200 W BRIDGE MONO MODE 8 ohms FTC 20 Hz - 20 kHz, 0.1% THD EIA 1 kHz, 0.1% THD 530 W 600 W 800 W 900 W 1100 W 1200 W 1300 W 1500 W 4 ohms EIA 1 kHz, 1% THD 830 W 1400 W 1800 W 2400 W Signal to Noise, 20 Hz-20 kHz 100 dB 100 dB 100 dB 100 dB Distortion (SMPTE-IM) Less than 0.01% Less than 0.01% Less than 0.02% Less than 0.02% Input Sensitivity @ 8 ohms 1.15V (+3.4 dBu) 1.15V (+3.4 dBu) 1.16V (+3.5 dBu) 1.23V (+4.0 dBu) Voltage Gain 31.6x (30 dB) 40x (32 dB) 46x (33 dB) 50x (34 dB) Output Circuitry AB AB Class H Class H Power Requirements 1/8 power pink noise at 4 ohms * 5A 6A 6A 7A ALL MODELS Distortion (Typical) 20 Hz - 20 kHz: 10 dB below rated power 1.0 kHz and below: full rated power Less than 0.03% THD, 4 and 8 ohms Less than 0.03% THD, 4 and 8 ohms Frequency Response 20 Hz-20 kHz, ±1 dB -3 dB points: 5 Hz - 50 kHz Damping Factor, 1 kHz and below Greater than 300 at 8 ohms Input Impedance 10k ohms unbalanced, 20k ohms balanced Input Clipping 10 Vrms (+22 dB) Cooling Continuously variable-speed fan, rear-to-front air flow Connectors, each channel Input: Active balanced; barrier strip, XLR and 1/4in (6.3mm) TRS tip and XLR (pin 2 positive) Output: touch-proof binding posts and Neutrik® Speakon® Controls Front: AC switch, Ch. 1 and Ch. 2 gain knobs Rear: 10-position DIP switch Indicators Power-On: Green LED Signal: Yellow LED (1 per channel) Clip: Red LED (1 per channel) Amplifier Protection Stable into reactive or mismatched loads Load Protection On/off muting, AC coupling (850, 1450), triac crowbar (1850HD, 2450, on each channel) Power Requirements 100, 120, 230 VAC, 50-60 Hz Dimensions 19in (48.3 cm) rack mounting, 3.5in (8.9 cm) tall (2 RU), 15.9in (40 cm) deep (rack mounting to rear support ears) Weight 35 lbs (15.9 kg) net 40 lbs (18.2 kg) net 44.5 lbs (20.2 kg) net 44.5 lbs (20.2 kg) net |
