QSC RMX2450a 2 channel, 500w /ch @ 8-Ohm, 750w /ch@ 4-Ohm, 1200w /ch @ 2-Ohm Power Amplifier

QSC RMX2450a 2 channels, 500w /ch @ 8-Ohm, 750w /ch@ 4-Ohm, 1200w /ch @ 2-Ohm

The RMXa Series amplifiers offer true professional-quality performance at an affordable price. With 800 watts per channel into 4 Ω and 1200 into 2 Ω, all in a chassis that is less than 16" deep, the RMX2450a is perfectly suited for performing musicians. The RMXa Series is an update on a proven line of amplifiers

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 (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
