Presonus - Digimax D8

8 Channel Preamplifier with 24 bit ADAT digital output

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.

The Lightpipe Kid

With its eight XLR mic inputs and eight ¼” balanced, direct channel outputs, you can route each channel’s signal independently. This makes the DigiMax D8 a premium front end for virtually any system.

And thanks to its eight-channel, 24-bit ADAT Lightpipe output (which operates at 44.1 or 48 kHz), the DigiMax D8 provides an excellent front end for Lightpipe-equipped digital-audio devices, such as Avid's Digi 003. You’ll immediately hear the improvement.

Better yet, add a DigiMax D8 to a Lightpipe-equipped PreSonus AudioBox 1818VSL. This combination provides a two-rackspace rig with 16 XMAX-equipped recording channels—enough to record an entire live band.

To keep your digital audio in sync with ultra-low jitter, the D8 receives word clock at its BNC connection and sends word clock via Lightpipe.

Careful, It’s Loaded!

In addition to its eight rear-panel mic inputs, the DigiMax D8 offers two front-panel instrument inputs so you can conveniently plug guitars into your system. All outputs are in the rear, keeping the wiring out of your face.

All of the key features you need are here: all eight preamps include variable trim control, 48V phantom power (switchable in odd-even pairs), ultra-fast acting LED metering, and a 20 dB pad.

The DigiMax D8 is a great solution for adding eight professional microphone preamplifiers to any digital recording system, especially a system with ADAT Optical expansion capability. It’s the perfect choice for expanding an AudioBox 1818VSL. And the price is so reasonable that your budget won’t need to expand!
