Big power in a small size.
The RMXa Series amplifiers from QSC offer true professional-quality performance at an affordable price. The 3-rackspace RMX4050a provides 2000 watts per channel at 2 ohms. It features a compact chassis less than 16" deep. RMXa amplifiers include a comprehensive set of features including XLR and 1/4" balanced inputs, Speakon and binding post outposts for convenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.
The RMX 4050a is a "heavy duty" model designed to work as hard into 2 ohm loads as most competing amplifiers will at 4 ohms. It features a three-tier, Class H design that is extremely efficient at real world power levels. Less AC current is wasted and more available current goes into producing useful audio power. 120 volt versions of the RMX4050a accomplish all this with a standard 15 amp plug.
High-current toroidal transformers
Independent user-defeatable clip limiters
Balanced 1/4" (6.3 mm) TRS, XLR, and barrier strip inputs
Touch-proof binding post and Neutrik Speakon outputs
Independent DC and thermal overload protection
Outrageous power, borderline indestructible and great-sounding. Order today.
