The Aes To Adat/Tdif Converter - Nuendo DD8 Operation Manual

6. The AES to ADAT/TDIF Converter

6.1 General
The Nuendo DD 8'S functional unit, which will be called 'left part' fur-
ther on, is an 8-channel format converter from AES/EBU to ADAT/TDIF,
with the output signal being transmitted both at the ADAT and TDIF
ports in parallel. As long as the device is not working in DS mode (Dou-
ble Speed), the output signal is even present at both ADAT and TDIF
ports (MAIN/AUX). Therefore the Nuendo DD 8 can pass on a 4 x 2
channel AES/EBU input signal to up to two ADAT and TDIF devices at
the same time (splitter 1 to 4). If AES is chosen as source in the right
part, there are the four AES/EBU outputs as well.
The four AES/EBU inputs process Double Speed (up to 96 kHz) and
Double Wire (up to 48 kHz) automatically. Excessive status displays
(Lock, SyncCheck, Emphasis, Level) help to avoid wrong configuration
and wrong clock setup.
A switchable high-end 8-channel sample rate converter can both con-
vert the sample rate and decouple the AES/EBU inputs.
6.2 Inputs
and copy protection are being ignored. Thanks to a highly sensitive in-
put stage, also SPDIF signals can be processed using a simple cable
adapter (Phono/XLR).
To achieve this, pins 2 and 3 of an XLR plug are being connected to the
two contacts of a Phono plug. The ground shield of the cable is only
connected to pin 1 of the XLR plug.
At the rear side of the
Nuendo DD 8 there are
four XLR sockets for the
AES/EBU inputs. Every
input is transformer-
balanced and ground-
free. Channel status
