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

Emphasis
The AES/EBU and TDIF interface of the Nuendo DD 8 support Emphasis.
Please note that an Emphasis indication will not be stored or processed
on the sound when doing digital transfers between AES/EBU or TDIF
and ADAT, because the ADAT standard does not include Emphasis.

7. The ADAT/TDIF to AES/EBU Converter

7.1 General
The Nuendo DD 8's functional unit called 'right part' further on, is an 8-
channel format converter from ADAT/TDIF to AES/EBU.
Because the Double Wire and Sample Split (S/MUX) formats don't con-
tain a coding, the Nuendo DD 8 cannot distinguish them from normal
(44.1/48 kHz) material. Whether the AES/EBU outputs are supposed to
work in Single (44.1/48 kHz) or Double Speed (88.2/96 kHz) has to be
set explicitly by the user. This happens in the clock section with the
sample frequency button, activating DS.
Complete status displays (Lock, SyncCheck, Emphasis, Level) help to
avoid wrong configuration and wrong clock setup.
7.2 Inputs
The Nuendo DD 8 provides two digital inputs, both in ADAT optical and
TDIF-1 format. The key SOURCE sets the desired input active.
In normal operation only the MAIN inputs are used. When using more
than the first 4 channels at activated DS (Double Speed), the AUX in-
puts also have to be used.
The input data is passed on to the four AES/EBU outputs in logical order:
ADAT/TDIF
AES/EBU
1 2 3
1L 1R 2L
4 5 6
2R 3L 3R
7 8
4L 4R
