Q Series Amplifiers
Q44, Q66, Q99 and
Q1212 rear view
Building on a legacy of power and performance,
Q Series amps take Electro-Voice’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 and 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 and Q66 models are based
on the proven Class-AB designs of EV’s reference-
standard Precision 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.
