The RMX 1450a amplifier from QSC offers true professional-quality performance at an affordable price. Three 2-rackspace range in power from 430 to 1200 w per channel at 2 ohms. Two 3-rackspace provide 2000 to 2500 w per channel at 2 ohms.

Description

The RMX 1450a features a compact chassis less than 16” deep. The RMX 1450a amplifier includes a comprehensive set of features including XLR and 1/4” balanced inputs, Speakon and binding post outposts for convenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.

Features

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.
Touch-proof 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.
