Hello everyone, I'm quite new to using forums but I'm having a problem that I can't seem to shake. I have a Roland Fantom X8 that I purchased on craigslist. The L and R outputs don't seem to work too well so I've been using the phones jack. This has worked for awhile now until I started getting a lot of static in my mix. I tried connecting my keyboard to many different amps but it doesn't seem to cure it. The strange thing is my headphones work without any of it. If anyone needs anymore info I'm happy to help, I appreciate your time.
