    Each new generation of Electro-Voice amplifiers inherits more than 60 years of experience in amplifer design and manufacturing.

    From the beginning, Electro-Voice has always considered the audio quality of an amplifier to be as important as the output power and reliability. An EV amp will do more than just work through the toughest conditions; it will ensure your system sounds its best while running safely.

    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. Failure was literally not an option with the P3000.

    As a vital part of the X-Array concert sound system, the P3000's performance was proven on the biggest world tours of the time, including the Rolling Stones and AC/DC. Moving forward into the 21st century, the IRIS-Net-controlled P3000RL followed suit on the largest tours and events of the era: LIVE8, Live Earth, Metallica, Kenny Chesney, and Foo Fighters, to name a few. As direct descendants of the legendary P3000, Q Series amps take Electro-Voice's unique amplifier design philosophy to a new level of performance, power, efficiency, and value.

    Innovative Class-H power:
    With Q Series' efficient Class-H design, the permanent voltage rail is designed to cover the average music signal, rather than permanently supplying the voltage for maximum output power. If dynamic peaks require a higher output voltage, the voltage rail is switched to the maximum. This process saves up to 50% of the power consumption found in conventional amplifier design, and results in a dramatic reduction in heat output. Q Series combines the sonic excellence and ruggedness of its Precision Series predecessors with Class-H innovation, all in a compact and affordable package.

    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. All these tests are carried out in EV labs during an amplifier's design phase, to ensure maximum sonic performance. While these technical explanations appear very complex, they are clearly audible. Take a Q Series amplifier and crank it up - you'll hear the difference immediately!

    Q-Series Amplifiers & Connectivity:
    Whatever application you choose, you can be sure your Q Series amp is prepared:
    Both inputs have a paralleled loop thru XLR output to route signal to other amp inputs.
    Besides the usual channel A & B outputs via Speakon connectors (on pin 1+/1-), output A carries the signal of channel B as well (on pin 2+ / 2-), providing an easy drive option for biamped speakers.
    Parallel & Bridge Mode option switches provide additional functionality with minimized cabling requirements.
    An additional switchable LPN (Low-Pass Notch) filter provides extra tonal fundament and kick, with protective Low-Cut for using smaller passive 12" or 15" cabinets without additional subwoofers.
