R-44

4-channel Portable Recorder

Q.How precise is the synchronization when two R-44s are connected via the CONTROL SYNC terminals?

A.When two R-44s are connected via the CONTROL SYNC terminals, they share the audio clock.
Therefore, delay due to time passing does not occur with recorded data.
In addition, the operation information is also sent, and start and stop operations are also synchronized. However, there is a time lag between two R-44s and the recording start time can slightly differ.

Reference:
The clock synchronization jitter is 1000ppm or less.
Difference of recording start time between two R-44s is approximately 10msec.
If pre-recording is set, the time lag becomes larger.
Because a time lag occurs with the recording star time as mentioned above, you need to use DAW or other tools to strictly align the phases after recording.
