NOTE 1: Recordings made at a sample rate other than the selected sample rate will play
back at the wrong speed. For example, if the sample rate is set to 44.1kHz and you try to play
back a recording made at 48kHz, the recording will play back slow. Therefore, please make
sure that your recordings are made at the correct sampling rate. Recordings made at different
sample rates cannot be used in the same project.
NOTE 2: 88.2kHz and 96kHz sample rates are only available via digital outputs in a special
‘dual-channel’ format. Please refer to the separate section for further information concerning
operation at these sample rates.
DIGITAL SYNC
Pressing Sync (F2) moves the cursor to the Digital Sync field.
This allows you to synchronise the DD8 to a variety of video and
wordclock synchronisation sources for precise system
synchronisation. The options available are:
INTERNAL CLOCK
This selection uses the DD8’s internal crystal as its sync source
and so the system is ‘free running’. This is the selection used when
using the DD8 on its own - when using it with external video equip-
ment, to prevent drift of audio to picture, it is recommended to sync
the entire system (i.e. VTR, DD8, etc.) to one of the external
wordclock or video sync sources described below.
DIGITAL INPUT
This synchronises the DD8 to the digital wordclock signal being
received from the optional digital audio interface (TDIF, ADAT or
AES/EBU).
NOTE 1: When recording through multiple digital inputs, these signals MUST ALL BE AT
THE SAME SAMPLING FREQUENCY .
PAL/SECAM Video
This synchronises the DD8 to a video sync signal through the
SYNC BNC connector on the rear panel. Typically, this will be used
in Europe to sync to a common PAL/SECAM house sync source.
NTSC 29.97Hz Video
This synchronises the DD8 to an NTSC 29.97Hz house sync sig-
nal through the SYNC BNC connector. This would normally be used
in Japan or America when 29.97 frames per second timecode is
being used.
NTSC 30Hz Video
This synchronises the DD8 to an NTSC 30Hz house sync signal
through the SYNC BNC connector. This would usually be used in
Japan or America when 30 frames per second timecode is being
used.
WORDCLOCK
This allows you to sync the DD8 to a wordclock signal through the
SYNC BNC connector. This is used with a Sony PCM1630, etc.
that has a separate SDIF wordclock output.
