QSC RMX 1450,  The QSC RMX Series amplifiers give you clean, dynamic power with the legendary QSC sound quality and reliability that pros depend on. The RMX Series deliver unmatched performance at a new breakthrough price.

Comprehensive Features
The RMX Series is packed full of professional features that increase performance and flexibility:

• The RMX  provides improved thermal performance that gives you higher continuous power in 2-ohms stereo or 4-ohms bridged applications (a RMX 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 1/4" 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.

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 1/4" (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
• 3-year warranty plus optional 3-year extended service contract
