1. Introduction
With the ADI-192 DD you have an incredibly versatile digital interface to your supply. The suc-
cessor of the highly successful
ADI-8 DD is a completely re-engineered device, designed to be
the most powerful format and sample rate converter ever. 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 Format Converter is the
perfect link between the formats mostly used today.
As a consequent continuation of RME's world-wide successful ADI series, the 192 DD also
contains elaborate technology and the latest integrated circuits. The ADI-192 DD is a uniquely
powerful and high-quality device, which will excite you even after many years of operation.
This manual has been divided into three parts:
•
The first part is written as quick start guide. Even the first time user will be successfully up
and running with most of the typical applications addressed by the ADI-192 DD.
•
The second part contains both basic and detailed information on all modes supported by the
ADI-192 DD, including sample multiplexing via Double and Quad Wire technology.
•
The third part contains useful background information about the methods and technologies
found in the ADI-192 DD.
In case you want to dive deeply into the powerful features of the ADI-192 DD, please start with
chapter 11.1, Terminology.

3. Brief Description and Characteristics
The ADI-192 DD consists of three 8-channel digital format converters, in a standard 19" box
with 1 unit height. The compact device has numerous extraordinary features like Intelligent
Clock Control (ICC), SyncCheck, SyncAlign, Bitclock PLL, patchbay functionality and active
jitter suppression through SteadyClock. Switchable high-end sample rate converters (SRC) in
reference quality allow for both sample rate conversion and clock decoupling on the highest
level.
All of the ADI-192 DD's I/Os support 192 kHz/24 bit. Since ADAT optical and TDIF are restricted
to 48 kHz, and AES is often limited to 48 or 96 kHz as well, the ADI-192 DD supports the so
called
Sample Multiplexing in a unique way. Be it Double Wire, Quad Wire, S/MUX or S/MUX4 –
the ADI-192 DD receives and transmits in all these modes, and turns out to be the world's only
sample rate converter that can operate in these modes using all three interface formats.
The format conversion between AES/EBU, ADAT and TDIF operates in all directions at the
same time. LEDs of different colours show the present state of incoming and outgoing signals
and of the internal processing in a clear way.
The unique Intelligent Clock Control (ICC) allows for a flexible use with internal clock (44.1 up to
192 kHz), external word clock, or the digital input signals, thanks to a clear and easily under-
standable display of the Lock and Sync states. In short: the ADI-192 DD is a true
Intelligent
Audio Solution .
