INTRODUCTION

Designed to help ease the transition to the digital world, the DI/O offers
high-resolution stereo 24-bit A/D-D/A conversion at switchable sample rates
from 44.1 to 96kHz. In external sync mode, the DI/O’s intelligent
synchronization allows for automatic sync to outboard equipment from
22kHz to 100kHz.

The DI/O can be used in a wide variety of applications including recording,
project, and home studios. Let the DI/O be the interface for your “classic”
analog signal processing gear in an all-digital production environment. It’s
the perfect interface for any computer-based recording system and gets the
A/D-D/A conversion process out of the noisy digital environment.

You can use the DI/O as your instrument’s direct-to-digital interface, thanks
to its high input impedance. Upgrade the A/D-D/As on your DAT machine or
older digital I/O equipment with the DI/O’s high-resolution converters. Get
more dynamic range on new samples and overdubs. You can loop thru the
DI/O to add “analog” warmth and musicality to an existing digital track.

The latest refinements in ART’s award winning tube pre-amp design are
integrated on the front end, before the A/D converter, for analog gain and
dynamic range control.  At the clean setting, the tube circuitry is virtually
bypassed and the A/D sees a “straight wire with gain” signal.  As you
increase the control the signal goes from ultra clean and transparent, thru
silky, to smooth, to warm, to fat.  At the warm end the tube becomes the
dominant gain element, enhancing lower and mid level signals and soft
limiting peaks and overshoots before they hit the A/D.

FEATURES:

• 2 channels of A/D and 2 channels of D/A conversion
• High Resolution 24-bit, 96kHz, 128x oversampling converter
• 44.1, 48, 88.2, 96kHz switch-selectable sample rates
• Intelligently syncs to external sample rates from 22kHz to 100kHz
• S/PDIF Coaxial, Digital inputs and outputs, RCA type jacks
• Hand-selected 12AX7A dual triode tube
• Fully variable tube character from transparent to warm
• ¼” High impedance stereo inputs and ¼” line level stereo outputs
• Variable input gain from 0dB(unity) to +20dB
