User manual ELECTRO-VOICE Q SERIES BROCHURE

[. . . ] In the 1990s, EV launched its Precision Series amplifiers. The flagship P3000's success was built upon its groundbreaking headroom, accompanied by electrical and thermal stability under all load conditions. [. . . ] 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. Sine wave and music signal on the output of an amplifier. 30% b a Specified output power, measured with sine wave signal. b The dynamic headroom designed into Electro-Voice amplifiers allows maximum dynamic response from music signals, providing more punch and power than other equally spec'd amps 100% a Transient Response When processing dynamic signals, other important criteria are signal speed and dynamic distortion. For example, kick drum signals carry pulses of many frequencies as an overlay spectrum. Therefore, and in contrast to many other manufacturers, EV specifies a lot more information on their amplifiers' dynamic behavior than just "slew rate" figures. Important tests referring to the amp´s ability regarding multitone signal pulses are expressed by IMD-SMPTE measurements at high power levels. And, while IMD tests show the Intermodulation Distortion behaviour (how much "sound" is added by the amplifier), DIM30 is the real spec for speed in an amplifier.
