Overview
Connectivity

* 1 x Stereo Analog I/O
* 1 x ADAT or SPDIF I/O (optical and coaxial, AES/EBU compatible)

The ADI-2 is a both compact and extremely flexible 2-channel Hi-End
AD/DA-converter. The small 9.5" unit offers top notch AD/DA-
conversion from/to SPDIF, AES and ADAT, at up to 192 kHz. Its
ability to use SPDIF, AES and ADAT format provides outstanding
compatibility. Whatever it is - simply get connected!

Key features of this extraordinary flexible converter are balanced
inputs and outputs, monitoring via headphone out, SteadyClock for
optimal converter quality, 3-stage hardware input and output level
control, and its capability to run on a wide range of power
supplied.

Features

The ADI-2 is equipped with a balanced stereo line input via two
Neutrik XLR/phones combo jacks, a balanced stereo line output with
XLR plus separate and simultaneously active phone jacks, as well
as an adjustable headphone output.

The analog inputs and outputs use the same circuit design as RME's
famous ADI-8 DS, guaranteeing outstandingly low noise and
distortion. Three different settings for the input and output
levels each provide perfect compatibility on analog domain. A
further highlight is SteadyClock(TM), a proprietary clock
technology for maximum jitter suppression. SteadyClock guarantees
superb sound quality completely independent from the quality of
the current reference clock. The ADI-2 uses the latest generation
of AD/DA-converters capable of up to 192 kHz sampling frequency at
S/N ratios up to 119 dBA.

But the ADI-2 has more to offer than tremendous sound, it also gives
you exciting digital connectivity. Its transformer-balanced
coaxial (RCA) SPDIF I/O has switchable Channel Status to make it
fully AES/EBU compatible. The optical TOSLINK I/Os can handle up
to 192 kHz and also serve as ADAT I/O with up to 96 kHz sample
rate. You can even use SPDIF input and ADAT output or vice versa
in AD/DA mode.

The clear layout and the distinct labeling of the front panel with its
functional buttons, the informative status displays, a 6 LED level
meter as well as the tidy functional back panel make it easy to
operate the unit right out of the box. Protective rack handles and
a strain-relief for power cord and audio cables are further useful
details that make the ADI-2 even more unique.

Power to this unit!

Following the 'Universal Power Supply' philosophy of RME's Digiface,
Multiface, QuadMic und OctaMic, the ADI-2 comes with an external
switching power supply. The unit's additional internal switching
power supply has been specially designed and optimized for audio
applications. It accepts any voltage from 7 to 30 V, be it AC or
DC, and even runs on batteries and rechargeable batteries.
