The PreSonus DigiMax D8 is an 8-channel microphone preamplifier with 24-bit ADAT optical output which provides an excellent front-end or expander for ADAT optical-equipped digital audio devices. The DigiMax D8 delivers incredibly high headroom, deep lows, smooth highs, and a rich overall sound.

Description

The PreSonus DigiMax D8 is an 8-channel microphone preamplifier with 24-bit ADAT optical output which provides an excellent front-end or expander for ADAT optical-equipped digital audio devices, such as the AudioBox 1818VSL, Studio 192, and Studio 192 Mobile audio/MIDI interfaces. For more than a decade, DigiMax-series preamp/converters have been relied on in countless recording studios worldwide. Based on the highly lauded XMAX Class A solid-state preamp, the DigiMax D8 has become a classic, offering eight of these prized preamps - enough to raise your entire studio rig to a higher level.

A good microphone preamp boosts a mic's level to almost 400 times that of the original signal, making the preamp one of the most important stages in an audio system. A cheap, off-the-shelf, op-amp-type mic preamp delivers thin, noisy, harsh results. In contrast, PreSonus® XMAX microphone preamps deliver incredibly high headroom, deep lows, smooth highs, and a rich overall sound. With XMAX preamps, your system's sound quality is limited only by the microphone you plug in.

Its complement of inputs and outputs makes the DigiMax D8 a versatile front-end for virtually any system. Two convenient front-panel instrument inputs let you plug in guitars, bypassing the mic inputs. All other connections are in the rear, keeping the wiring out of your face. With eight XLR mic/line inputs, you can plug in virtually any mic- or line-level sound source. Eight 1/4", balanced, direct channel outputs allow you to add preamps to devices with line-level inputs or split the mic preamps between two devices.

Eight-channel, 24-bit, 44.1/48 kHz ADAT Optical ("Lightpipe") output makes the DigiMax D8 an excellent way to add more analog inputs to any third-party, Lightpipe-equipped digital-audio device. Better yet, add a DigiMax D8 to a Lightpipe-equipped PreSonus AudioBox 1818VSL for a 2-rack space 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 ADAT Optical.

The DigiMax D8 is a proven solution for adding eight professional microphone preamplifiers to any digital recording system. You can easily integrate it into your studio, thanks to plentiful I/O, variable trim control for each preamp, 48V phantom power (switchable in odd-even pairs), fast-acting LED metering, and a 20 dB pad. And you'll love its sound!
