Hello, thank you for reply again,
I try to use the XLR input the eclipse,
its better sound than I heard the distortion noise, but its still too low volume.
May it be the I/O board problem?
Our country distributor without any help,
so the only way is to send it to the U.S eventide maintain station? or maybe can replace the parts on our local distributor?
Really thank you for your help.
