1. Introduction

Congratulations on your purchase of a ADI-2. This hi-quality analog to digital and digital to ana-

log converter includes AES/SPDIF and ADAT optical digital interfaces. It represents a sophisti-

cated, highly flexible and universal tool. Advanced circuit technology combined with latest inte-

grated circuits result in a unique and outstanding device, meeting highest quality standards.

The ADI-2 will excite you even after many years of operation.

Please check that your ADI-2's package contains each of the following:

The ADI-2 is a 2-channel analog to digital and digital to analog converter in a half-rack (9.5")

enclosure of 1 U height. Latest 24 bit / 192 kHz converters offer up to 119 dBA dynamic ratio.

This value is not only printed in the brochure, thanks to our Low Jitter Design it is available with

every sold unit.

The servo balanced analog inputs and outputs are fitted with both XLR and 1/4" TRS jacks. The

signal path from the jacks to the ADC is completely symmetrical. Both signal paths A/D and

D/A are internally DC-coupled, for highest phase accuracy at lowest roll-off. The digital inputs

and outputs are available as AES/EBU, SPDIF coaxial and optical, as well as ADAT optical.

To maintain the full dynamic range within the best operating level, RME's ADI-2 includes elec-

tronic switches of the latest technology, which introduce no additional noise or distortion to the

audio path. Two switches on the front panel let you control input and output level for a perfect

adaptation to the most often used standards -10 dBV and +4 dBu. Two compact level meters

provide 6 LEDs each. Multiple brightness stages and peak hold functionality make reading and

adjusting input levels easy and convenient.

The ADI-2 can provide all sample rates between 32 kHz and 192 kHz. The unique Intelligent

Clock Control technology (ICC) offers a flexible operation with internal clock and the digital

input signals. Furthermore, RME's SteadyClock guarantess exceptional performance in all

clock modes. Thanks to a highly efficient jitter suppression, the AD-conversion always operates

on highest sonic level, being completely independent from the quality of the incoming clock

signal.
