Q Series Amplifiers
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.
