QSC RMX 4050a

This heavy-duty model is designed to work as hard at 2-ohm loads as most competing amps will at 4 ohms. With a 3 rack unit, Class H design, it is extremely efficient. Delivers 1,600W/ch. at 2 ohms, 1,300W at 4 ohms, 800W at 8 ohms and 2,600W at 8 ohms bridged. It features a dual mono high-current power supply, high-current toroidal transformers, independent user-defeatable clip limiters, selectable low-frequency filters (30Hz or 50Hz), balanced 1/4" TRS, XLR and barrier strip inputs, binding post and Neutrik speakon outputs, front mounted gain control, signal and clip LEDs. 3RU chassis only 16" deep.

• 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 (120V)
• 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
• 3-year warranty plus optional 3-year extended service contract
