SETUP > RECORD SETTINGS > PRE-RECORD TIME
The Pre-Record time can be set from zero up to 20 seconds. The selected value may not always be possible
due to the physical limitation of the built-in memory. The Pre-Record time depends on following factors:
•
Number of Tracks being assigned
•
Sampling frequency
•
Sample Rate and Pull UP/ Pull DOWN correction
When the required pre-record time is not possible, the SX-R4 will perform on "best effort" basis to provide
with the maximum possible. The table below shows the maximum values of the pre-record time [seconds]:
