Product Overview

The QSC RMX4050a amplifier is a 3RU unit designed for high power live sound reinforcement applications. The amplifier features both XLR and 1/4" balanced inputs as well as Speakon and touch-proof binding post output connectors. The integrated user-defeatable clip limiters and selectable low-frequency filters allow you to adjust the amplifier to your application.

The amplifier is rated at 850W per channel at 8Ω from 20 to 20,000 Hz, 1400W per channel at 4Ω from 20 to 20,000 Hz, 2000W per channel at 2Ω from 20 to 20,000 Hz, and 2800W in bridge mono mode at 8Ω from 20 to 20,000 Hz.

This unit is less than 16" deep and features a three-tier Class H output circuit design for efficient power management. As a result, less AC current is wasted and more available current is utilized for amplification

Features:

Compact size — up to 5000 watts in three rack spaces
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
The 4000-watt RMX4050a operates on a standard 15 amp plug (120V)
The RMX4050a features a dual mono, high-current power supply for increased reliability and performance
The RMX4050a's particularly exceptional combination of cooling capacity and electrical efficiency provides robust thermal performance suitable for high continuous power in 2-ohm stereo or 4-ohm bridged applications.
Balanced 1/4-inch (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 for monitoring performance
Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
