sample frequency of the mixing desk – but not identical. Remedy: To drive the ADAT re-
corder from its digital input, set it to slave mode (DIG), and connect the input to the
Nuendo 96/52's ADAT3 output. Nuendo 96/52 is already in sync with the mixing desk,
so it will send an identical (synchronous) signal to ADAT3 out. The ADAT recorder will
lock onto this, its output will also be in sync. The signal from the ADAT recorder is now
fully in sync with the signals from the mixing desk.
Thanks to the its "AutoSync" technology and a lightning fast PLL, the Nuendo 96/52 is
not only capable of handling standard frequencies, but also any sample rate between
25 and 105 kHz. The input selected in "Pref Sync Ref" serves as the synchronization
source. If the Expansion Board has been installed, and the word clock input is selected
(clock mode "Word Clock"), this will serve as the synchronization source, allowing any
sample frequency between 25 kHz and 56 kHz in varispeed operation.
The current sample frequency at the S/P-DIF input (displayed in the "S/P-DIF In" field)
is useful for troubleshooting and checking the configuration of all connected digital
devices. If an input without a valid signal (or a faulty one) is selected, "No Lock" will ap-
pear. In varispeed mode, or if the sample frequency is way out of tune, "Lock" is dis-
played.
At 88.2 or 96 kHz, the sample frequency shown in the "S/P-DIF In" field differs from the
one shown in "Sync Ref", if one of the ADAT inputs has been selected in "Pref Sync
Ref". The card automatically switches to its Sample Split mode here, because ADAT
optical inputs and outputs are only specified up to 48 kHz. Data from/to a single input/
output is then spread onto two channels, the internal frequency stays at 44.1 or 48
kHz. In this case, the ADAT recorder sample frequency is therefore only half the S/P-
DIF frequency.
