Professional musicians and mobile entertainers can now access studio-grade amplification without breaking the bank, thanks to the RMXa Series amplifiers that pack serious power into remarkably compact chassis designs. The RMX850a delivers 300 watts per channel into 4 ohms and 430 watts into 2 ohms, all within a chassis measuring less than 16" deep, making it ideal for performers who need reliable power in tight spaces.
These amplifiers showcase impressive engineering with high-current toroidal transformers that provide superior 2-ohm power output whilst maintaining low noise levels. The RMX4050a stands out by operating on a standard 15 amp plug at 120V despite its 4000-watt capability, whilst both the RMX4050a and RMX5050a feature dual mono, high-current power supplies for enhanced reliability. The series offers remarkable power density, fitting up to 2500 watts in two rack spaces or 5000 watts in three rack spaces.
Practical features include independent user-defeatable clip limiters to reduce distortion, selectable low-frequency filters at 30 Hz or 50 Hz for speaker protection and increased headroom, plus front-mounted gain controls for easy access during performances. Connectivity options are comprehensive with balanced 1/4" TRS, XLR, and barrier strip inputs, complemented by touch-proof binding post and Neutrik Speakon® outputs. Signal and clip LED indicators provide real-time performance monitoring, whilst independent DC and thermal overload protection on each channel automatically safeguards both amplifier and speakers, all backed by a 3-year warranty with optional extended service contract available.
