About this model

The QSC RMX2450 is a 2-channel power amplifier built around 2-tier Class H output circuitry and high-current toroidal transformers, delivering 450 W per channel at 8Ω and 650 W per channel at 4Ω in stereo mode, scaling up to 2400 W in bridge-mono at 4Ω. It fits in a compact 2-rack-space chassis under 16 inches deep, making it practical for both installed and portable applications.

A rear 10-position DIP switch allows configuration of independent clip limiters and selectable low-frequency filters at 30 Hz or 50 Hz, with independent DC and thermal overload protection per channel.
