3. Brief Description and Characteristics

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 hi-power/hi-end
headphone output provides reference sound. 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 guarantees 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.
