It has been confirmed that after updating to Ver.5.00, when you turn on the power with the INPUT2 (audio input 2) switch set to LINE, the audio from CH2 may become unintended level. Due to this issue, we have suspended the download of V5.00.
For customers who have already updated to Ver.5.00, please change the INPUT2 (audio input 2) switch to MIC and then back to LINE to use the device normally. Please wait for a while until the corrected version is released. (May 31, 2024)
