The PD4 series is a high-end speaker with 2 amplifiers for great performance. The low-frequency is powered by a class-D amplifier, while the high-frequency gets its power from a class-AB amplifier. The PD4 features a built-in DSP with 4 preset modes for speech, PA, sub and monitor sound settings. In sub mode the speaker can be used as a top in combination with a subwoofer. This series has been designed in a polypropylene construction both to handle the power and still lightweight enough for mobile use. The perfect speaker for any DJ or live-performer but also suitable for monitor use or club installation.
