650 W Per Channel Power Amplifier

Building on a legacy of power and performance, Q44-II amps take Electro-Voice’s unique amplifier philosophy to a new level of efficiency and value. The Q44-II achieves superb audio performance because it's designed for superior dynamic headroom and transient response, resulting in 30% greater output capability for short-duration signals. High-power Q Series models use sophisticated Class-H topology that dramatically reduces heat and cuts energy consumption by up to 50%, yielding racks that are easier to power and easier to cool.

Smaller Q series models are based on the proven Class-AB designs of EV’s reference-standard P series. All models incorporate dynamic limiting to prevent dangerous output clipping, as well as extensive protections against thermal damage and electrical malfunction. Combining Class-H innovation with the sonic excellence and robustness of its Precision series heritage, the compact, affordable Q series is the ideal amplifier line for all sizes of clubs, concerts, performance centers, and sports venues.
