QSC RMX1450a Low-Z Power Amplifier, 500W / Channel 4Ω, LED Indicators for Power, Signal, Clip, Built-In Protection Circuits, Balanced 1/4" TRS, XLR, User-Defeatable Clip Limiters, Black | RMX1450A

The 500 watts per channel 4Ω QSC RMX1450a Low-Z 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.

• 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

QSC RMX1450a Power Amplifier at a Glance:

• Compact chassis leaves more room in your rack
• Quality connections for reliable performance
• Optimize your sound with a switchable low-cut filter

Compact chassis leaves more room in your rack

Rack space counts, especially when you're touring the country with tons of equipment. The QSC RMX1450a packs a ton of power into a chassis that's less than 16" deep, which gives you more room to make connections and manage your rack equipment.

Quality connections for reliable performance

The QSC RMX1450a power amplifier has both XLR and 1/4" balanced inputs, plus vinding post and speakON outputs for maximum convenience. Whether you're playing at the local club or managing a large-scale stage production, it's easy to integrate the QSC RMX1450a into virtually any system that requires powerful, transparent audio performance.

Optimize your sound with a switchable low-cut filter

There's a low-cut filter on the QSC RMX1450a, to help protect your speakers and also help you maintain more headroom. Set it at 30Hz if you're using the RMX1450a to power a subwoofer, giving you powerful low-frequency response while filtering out sub-sonics that eat up your headroom. Set it to 50Hz if you're powering main speakers, giving you even more headroom for clear, dynamic, full-range sound while maintaining powerful low-end presence.
