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 RMX1450a delivers 500 watts per channel into 4 ohms and 700 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.
Smart protection features include independent user-defeatable clip limiters that reduce distortion, plus selectable low-frequency filters at 30 Hz or 50 Hz to protect speakers and increase headroom. Each channel benefits from independent DC and thermal overload protection that automatically safeguards both amplifier and connected speakers. Connectivity options are comprehensive, featuring balanced 1/4" TRS, XLR, and barrier strip inputs, alongside touch-proof binding post and Neutrik Speakon® outputs.
Practical design elements include front-mounted gain controls for easy access during performances, plus signal and clip LED indicators for real-time performance monitoring. The RMX4050a’s exceptional cooling capacity and electrical efficiency provide robust thermal performance suitable for demanding applications including high continuous power in 2-ohm stereo or 4-ohm bridged configurations. All models come with a 3-year warranty, with an optional 3-year extended service contract available for additional peace of mind.
