FEATURES

• Compact size — up to 2500 watts in two rack spaces, or 5000 watts in three rack spaces
• High-current toroidal transformers, for greater 2-ohm power and low noise
• Independent user-defeatable clip limiters reduce distortion
• Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
• The 4000-watt RMX4050a operates on a standard 15 amp plug (120 V)
• Both the RMX4050a and the RMX5050a feature a dual mono, high-current power supply for increased reliability and performance
• The RMX4050a's particularly exceptional combination of cooling capacity and electrical efficiency provides robust thermal performance suitable for high continuous power in 2-ohm stereo or 4-ohm bridged applications.
• Balanced 1/4-inch (6.3 mm) TRS, XLR, and barrier strip inputs
• Touch-proof binding post and Neutrik Speakon® outputs
• Front mounted gain controls for easy access
• Signal and clip LED indicators for monitoring performance
• Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers

DESCRIPTION

The 300 watts per channel 4Ω QSC RMX850a Power Amplifier is a 2RU rack mountable amplifier designed for live sound reinforcement applications. The amplifier features two Class AB output channels that can operate in either stereo or mono bridge mode. The unit operates on a standard 15 amp plug and utilizes high-current toroidal transformers for less noise and better performance when pushing a 2 ohm load. To reduce distortion, the amplifier utilizes independent user-defeatable clip limiters and includes LED indicator lights to show the presence of the signal and when the signal is clipping.
