Add another 8 channels of high quality Presonus preamps to your existing audio interface using the ADAT digital connection and you will instantly expand your studio. A high-quality microphone preamp can make all the difference in the sound of your recordings. Without a quality preamp, the expression “garbage in, garbage out” is especially apt. And customers and reviewers alike have long insisted that the PreSonus XMAX™ Class A solid-state preamp is the finest in its price class. The DigiMax D8 provides eight of these prized preamps-enough to raise your entire studio rig to a higher level. And that's just the beginning of the story.
