Building on a legacy of power and performance, Q Series amps take Electro-VoiceÂ’s unique amplifier philosophy to a new level of efficiency and value. The Q series 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 Q99 & Q1212 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 Q44 & Q66 models are based on the proven Class-AB designs of EVÂ’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 Class-AB sonic excellence and robustness, the compact, affordable Q series is the ideal amplifier line for all sizes of clubs, concerts, performance centers, and sports venues.
