10-2 Using External Synchronization and Two Channel Digital Audio Input
and Output
Example synchronization signal connections (2)
This example uses a PCM-3324S Digital Audio
Recorder as the other digital audio device, and a PCM-
1630 Digital Audio Processor system.
The video equipment and PCM-3348HR are
synchronized by a composite video signal, and the
PCM-3324S and PCM-1630 system both use a word
sync signal for synchronization. The digital audio
signal input uses the SDIF-2 (BALANCE) INPUT
connector and SDIF-2 (UNBALANCE) INPUT
connector simultaneously.

In this configuration the slave and master units must
have the same sampling frequency. You can use 44.1
kHz or 44.056 kHz as the sampling frequency.
If using this configuration with an additional time
code synchronizer for synchronized operation, set the
VARI SYNC switch on the PCM-3348HR MC board
to OFF. If this switch is set to ON, this results in
variable speed playback, and the digital I/O
synchronization with the PCM-1630 system will be
lost.
