QSC RMX1450 1400W POWER AMPLIFIER

The QSC RMX 1450 Power Amplifier gives you clean, dynamic power with the legendary QSC sound quality and reliability that pros depend on.

The QSC RMX 1450 Power Amplifier delivers 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.

The QSC RMX 1450 Power Amplifier main features include:

• 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.
• 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 1/4" (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
