The ZPR-3520V2 is a 3-Zone mixer / preamplifier with two stereo and one mono zone output. On the choice of the installer, the zones can be level-controlled by either the internal front-panel control or an external potentiometer control (ZCP10A, optional). Every output zone’s source signal can be freely chosen from any of the 4 stereo inputs, with two of these stereo inputs re-routable to the front side 3.5mm TRS stereo input and the rear-side balanced stereo input (FOH), thus providing connectivity to both mobile players and balanced sources like a connected DJ or stage mixer. Two microphone inputs with switchable priority can either be included or excluded in/from every zone. Additional 2-Band EQs for every zone output and the music mute and emergency signal inputs with automatic priority make the ZPR-3520V2 a truly versatile core of any installed sound system.
