1. Introduction
WiththeNuendoDD8youhaveanincrediblyversatiledigitalinterface
to your supply. What at first looks like a simple AES/TDIF/ADAT format
converter turns out to be the universal problem solver at a closer look.
From small project studios to broadcast and television, the Universal
FormatConverter is the perfect link between the formats mostly used
today.
The Nuendo DD 8 contains elaborate technology and the latest inte-
grated circuits, delivering 8 full channels in 24 bit and 96 kHz. The Nu-
endo DD 8 is a uniquely powerful and high-quality device, which will
excite you even after many years of operation.
2. Package Contents
Please check that your Nuendo DD 8 package contains each of the fol-
lowing:
•Nuendo DD 8
•Manual
•Power chord
•Optical cable 2 x 2 m (TOSLINK)

All of the Nuendo DD 8's I/Os support 96 kHz/24 bit. As ADAT optical
andTDIFarerestricted to48kHz,inDSmode (DoubleSpeed)twochan-
nels are being used for the transmission of one channel's data. The
SampleSplit algorithm used is also implemented in Steinberg’s
Nuendo 96/52. Thus the Nuendo DD 8 also serves as an ideal AES/EBU
frontend for these interface cards, on both Mac and PC.
The format conversion between AES/EBU and ADAT/TDIF operates in
both directions at the same time, both completely independent or in-
telligently coupled. LEDs of different colours show the present state of
incomingandoutgoingsignalsandoftheinternalprocessinginaclear
way.
The unique Intelligent Clock Control (ICC) allows for a flexible use with
internalclock(44.1,48,88.2and96kHz),externalwordclockorthedig-
ital input signals. These options being available for both directions are
intelligently coupled in a way typical for Steinberg and easy to apply
thanks to a clear and easily understandable display of the Lock and
Syncstates. Besides, theunique CopyMode allows for operationas dig-
ital patchbay and signal distributor. Up to 16 channels can be distrib-
uted and converted at the same time. In few words: The Nuendo DD 8
is a true IntelligentAudioSolution .

5. First Usage –Quick Start
The user interface of the Nuendo DD 8 is characterized by a clearly
structuredarchitectureandanunambiguouslabellingofthefrontand
rearsides.Thedevicecanthusbeusedwithoutamanualwithoutprob-
lems, because numerous LEDs show the state of the device and all in-
coming and outgoing signals in a strictly logical way.
However, we have to question this statement a little, because we
couldn'tstopourselvesandintegrated everything in the Nuendo DD 8
that we could think of and that was in any way possible. As a conse-
quence, you will find some application examples in chapter 10 that
break up the logical structure of the front board. Those are however
very special applications for professionals, where we anticipate both
the understanding of those modes and the ability to read a manual.
Whenbeing switched on for thefirst time, theNuendo DD 8comes up
in a default mode, which should be appropriate for most applications.
Both converters are set to their typical format conversion modes, and
synchronize to the input signals.

•SOURCE: AES
