My church is trying to record the services onto a SD card using our SL 24 Series III. I am up front playing guitar so I cannot see what is being done in the booth, but when I get the SD card so that I can edit and upload the teachings in the form of a podcast, I get almost no volume on the track. I've tried everything and the whole recording is near silent. What can I adjust on the SL 24 BEFORE they record everything? Thanks!
