PreSonus ADL 700 High Voltage Tube Channel Strip

Beyond superb sound quality, the ADL 700’s preamp is special because of its ease of use and flexibilityThe full-featured FET compressor in the ADL 700 was custom-designed to work with the ADL tube preamp and the new ADL 700 EQThe ADL 700’s 4-band semi-parametric EQ was designed to match the preamp and compressor. It combines isolated filters and optimized, per-band Q to provide subtle signal-shaping without harsh artifactsWe've given the ADL 700 all the features you expect in a high-end professional channel strip, with flexible features that let you work the way you want to
