1. Introduction
With the ADI-2 FS, RME introduces the successor to the renowned ADI-2. Although the ADI-2
FS has been completely redesigned – for example with the complete analog input stage of the
award-winning ADI-2 Pro - it still has the same, easy operation and I/Os as its predecessor.
During its development some useful improvements were also added. The step-less adjustment
of the rear output level can be activated directly on the front instead of internal jumpers. The
new ANA option, which realizes an analog bypass from the analog input to the analog output,
gives the ADI-2 FS a cornucopia of applications beyond AD and DA conversion. And naturally
the ADI-2 FS comes with RME's latest SteadyClock.
Mute relays on XLR and Phones Out and four times the output power at the headphone output
with only 0.1 ohm output impedance make the ADI-2 FS, among other things, an ideal, low-
priced supplement to all RME interfaces up to the ADI-2 Pro. The ADI-2 FS provides these
devices with two additional analog inputs and outputs and an additional headphone output.
The ADI-2 FS is a high quality, yet highly flexible and universally applicable tool. Advanced
circuit technology combined with latest integrated circuits result in a unique and outstanding
device, meeting highest quality standards. The ADI-2 FS will excite you even after many years
of operation. The ADI-2 FS works as:
x
AD/DA converter in professional studio quality
x
Powerful headphone amplifier with analog and digital input
x
Multi-format converter (AES, SPDIF, ADAT) with monitoring
x
SPDIF/ADAT playback system
x
Analog impedance converter
x
Analog level adaptation
x
Analog balanced converter (unbalanced to balanced)
x
Analog distribution amp

3. Brief Description and Characteristics
The ADI-2 FS 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 120 dBA dynamic range. This
value is not only printed in the brochure – it is what the unit achieves in real-world operation.
The servo-balanced analog inputs and dedicated balanced and unbalanced outputs are fitted
with both XLR and 1/4" TRS/TS jacks. The unit's analog input stage uses a fully balanced and
DC-coupled circuit design, for highest phase accuracy at lowest roll-off.
The Hi-Power² headphone output provides reference sound. The digital inputs and outputs are
available as SPDIF coaxial (AES/EBU compatible), SPDIF optical and ADAT optical.
