Description
The QSC RMX4050A 2000W Professional Low-Z Power Amplifier is a 3RU unit designed for high power live sound reinforcement applications. The amplifier features both XLR and 1/4" balanced inputs as well as Speak on and touch-proof binding post output connectors. The integrated user-defeat able clip limiters and selectable low-frequency filters allow you to adjust the amplifier to your application.
The amplifier is rated at 850W per channel at 8Ω from 20 to 20,000 Hz, 1400W per channel at 4Ω from 20 to 20,000 Hz, 2000W per channel at 2Ω from 20 to 20,000 Hz, and 2800W in bridge mono mode at 8Ω from 20 to 20,000 Hz.
This unit is less than 16" deep and features a three-tier Class H output circuit design for efficient power management. As a result, less AC current is wasted and more available current is utilized for amplification.
