Sounds like a input monitor issue. So if you are listening to the input or listening to the input after it's processed. There seems to be 4 dip switches on the back, the 3rd may be the solution,. From the manual
[INPUT MONITOR] Switch
These are miniature switches that you can move upward or downward when you want to change various settings.
This specifies whether the audio signal received at the GUITAR/MIC jack, the MIC
(PLUG-IN POWERED) / DIGITAL IN jack, and INPUT jacks will be output from the
PHONES/DIGITAL OUT jack and the OUTPUT jacks.
ONSwitch DownThe audio input signal will be output directly from the PHONES/DIGITAL OUT jack and the OUTPUT jacks.
* If the [REC SOURCE] switch (P.14) is set to DIGITAL, the PHONES/DIGITAL OUT jack
and OUTPUT jacks will output the audio that was received in digital form at the MIC
(PLUG-IN POWERED) / DIGITAL IN jack, regardless of the setting of this switch
Try changing the switch position. It does say something about this being able to be done from the software, so also try that.
