Stunning high-end sound and incredible versatility are hallmarks of this top-of-the-line, tube-driven channel strip. The ADL 700 integrates a proven, award-winning, boutique-quality preamp; a custom-designed FET compressor; and a custom, four-band, semi-parametric EQ.

Our premium channel strip boasts frequency response from 10 Hz all the way up to 45 kHz and offers all of the features you'd want in a high-end device. And the ADL 700 is a great value — as you expect from PreSonus!

We created the ADL 700 because you insisted! The PreSonus ADL 600 two-channel tube mic preamp was such a hit with customers—including such top artists, engineers, and producers as Chuck Ainlay, Jimmy Douglass, Mark Mancina, Demetric Collins, and Victor Wooten—that we were inundated with requests for a single-channel version in a channel strip, with a compressor and EQ that would be up to the preamp's high standards.

You were right—it was a great idea—so we gave the design job to Robert Creel, the engineering mastermind behind many of PreSonus' most beloved analog circuits, including the XMAX™ preamp. It took years of hard work but he delivered big-time. The ADL 700 channel strip is everything we—and you—hoped it would be!
