QSC RMX 4050 Power Amplifier High-Power Professional 3U Touring Amplifier

QSC RMX 4050 Power Amplifier High-Power Professional 3U Touring Amplifier

At the core of the QSC RMX 4050 Power Amplifier is a dual mono high-current power supply system, designed to improve channel separation, stability, and overall power delivery. This architecture ensures consistent performance even when driving low-impedance loads in demanding sound reinforcement environments.

The amplifier is capable of operating in both stereo and bridged configurations, making it suitable for powering full-range loudspeakers as well as high-output subwoofer systems. It supports operation into 2-ohm stereo loads and 4-ohm bridged loads, giving it flexibility across a wide range of professional PA setups.

The QSC RMX 4050 Power Amplifier includes independent user-defeatable clip limiters that help prevent distortion and protect connected speakers during high-level operation. Selectable low-frequency filters (30Hz or 50Hz) allow system tuning to match different speaker types and improve system headroom.

Connectivity options include balanced XLR, TRS, and barrier strip inputs, ensuring compatibility with a wide range of professional audio equipment. Output connections are provided via Neutrik Speakon and touch-proof binding posts for secure and reliable speaker wiring.

Advanced cooling and efficient thermal design allow the amplifier to maintain stable performance during extended high-power use, making it suitable for touring and fixed installations where reliability is critical.
