เพาเวอร์แอมป์ ยี่ห้อ EV Electro-Voice รุ่น Q44ii Amplifier The Q44 is based on EV’s reference-standard P-Series. It guarantees the same high-quality construction and output with a maximum power capability of 2×450 watts @4 Ohms. The Q44 is designed for cost-limited mobile applications and an excellent choice for small full-range tops and utility loudspeakers such as ZX1 Sx Series or EVID series.
Amplifier power and distortion figures are typically specified with sine wave signals. However music signals are far more dynamic than sine waves comprising a pulsed wideband spectrum.
We at EV believe that above all figures the tonal performance of live music counts most; therefore all of our amplifiers are designed for dynamic headroom. This means that each and every EV amp has at least 30% more output capability for short-term signals when compared to a long-term sine wave value. This additional headroom results in an amp that will for example allow for short term signal peaks of at least 780W when spec´d 600W.
While dynamic headroom is audible when playing music through a sound system another specification to observe is the increase in output power from an 8 Ohm load to 4 Ohms and then down to 2 Ohms. Of course all Electro-Voice amplifiers are designed to be absolutely stable into loads of 2 Ohms.
