ADI-8 DS MK III
8-Channel 192 kHz High-End ADAT & AES/EBU Converter &
Digital Format Converter & Digital PatchBay

ADI-8 DS MK III
The ADI-8 DS Mk III is a highly flexible 8-channel AD/DA 
converter and digital to digital format converter with an 
unrivalled bunch of features. The device combines 
excellent analog circuit design with outstanding low 
latency AD/DA converter chips. Along with SteadyClock, 
the QS offers AD and DA conversion of the highest quality, 
redefining the reference class of analog/digital converters.
The compact 1U device provides a host of extraordinary 
features, including 4 hardware reference levels up to +24 dBu, 
AES/EBU and ADAT I/O up to 192 kHz, and a comprehensive 
Patch Mode.
The ADI-8 DS Mk III uses a completely symmetrical signal path, 
that guarantees an exceptional sound quality, outstanding low 
distortion and highest Signal to Noise ratio in all level settings. 
To maintain the full dynamic range within all operating levels 
the ADI-8 DS Mk III uses discrete gain stages which are 
switched electronically, so that no additional noise or distortion 
is introduced into the audio path.         
Sophisticated AD/DA converters provide sample rates up to 
192 kHz with a SNR of 120 dBA. On the digital side, SteadyClockTM, RME’s unique clock technology and jitter suppression, 
further enhances the list of features, ensuring the best sound 
quality regardless of the quality of the reference clock signal.
Of course other typical RME features such as Intelligent Clock 
Control (ICC), SyncCheck 
implemented.
The specially developed internal high performance switching 
power supply provides operation with voltages ranging from 
100 to 240 AC Volts. It is short-circuit proof, has an integrated 
line filter, is fully regulated against voltage fluctuations, and 
suppresses mains interference.
Analog Outputs. The ADI-8 DS Mk III has separated driver 
stages for the TRS and D-sub outputs. The servo-balanced TRS 
jacks will work up to +21 dBu. When selecting +24 dBu the 
balanced D-sub connector outputs will provide the higher 
output level while TRS stays at +19 dBu.
TM
 and SyncAlignTM have also been 
2 ADAT I/Os support up to 8 channels at 96 kHz (S/MUX) and 4 
channels at 192 kHz (S/MUX4). 
A 25-pin AES/EBU interface features 8 channels at 192 kHz.    
All outputs can be used simultaneously, i.e.: analog (balanced 
TRS and/or D-sub), ADAT, AES/EBU.
Analog Inputs. The ADI-8 DS Mk III provides inputs via TRS or 
D-sub connectors. Both operate servo-balanced and accept 
levels up to +24 dBu.
Digital Patch Mode. A digital patchbay with free choice of 
source and destination setup can be used to convert ADAT to 
AES, AES to ADAT, cross-convert them at the same time, pass 
ADAT on to ADAT while monitored analog, and many more. 
The ADAT outputs also feature copy mode for connection of 
two different ADAT devices. These powerful and easy to use 
modes add significant value to the already outstanding 
conversion quality.
