The QSC RMX 5050a power amplifier packs an impressive 5000 watts into just 3 rack spaces, making it a powerhouse solution for professional sound reinforcement. This Class H design amplifier has been optimised for touring professionals, performing musicians, and mobile entertainers who demand sustained high power output with exceptional audio performance. The three-tier Class H topology ensures remarkable efficiency at real-world power levels, converting more AC current into useful audio power rather than wasting it as heat.
Built with high-current toroidal transformers, the RMX 5050a provides superior 2 ohm power handling and reduced noise compared to conventional designs. The amplifier incorporates component upgrades that boost peak power by 25% over its predecessor, the RMX 4050a, whilst maintaining the road-proven reliability that QSC is known for. Independent user-defeatable clip limiters work to reduce distortion, while selectable low-frequency filters at 30 Hz or 50 Hz protect connected speakers and increase available headroom.
Connectivity options include balanced 1/4" TRS, XLR, and barrier strip inputs, with touch-proof binding posts and Neutrik Speakon® outputs ensuring secure connections. Front-mounted gain controls provide easy access during setup, while signal and clip LED indicators allow real-time performance monitoring. Each channel features independent DC and thermal overload protection, automatically safeguarding both the amplifier and connected speakers from damage.
