The RMXa Series is an update on a proven line of amplifiers line of amplifiers combining legendary QSC reliability, audio performance and affordability. Entertainers and touring users can continue to rely on the RMXa as one of the leading amplifier series in the world. For mid-power applications, the 2RU models offer 4Ω power ratings from 300 to 800 watts per channel. For premium speaker systems with extremely high power capacity the 3RU models (RMX 4050a and RMX 5050a) are unchallenged.
With 300 W/CH into 4 ohms and 430 W/CH into 2 ohms all in a chassis that is less than 16" deep the RMX850a is perfectly suited for performing musicians and mobile entertainers.
