Thread: Troubleshoot this hiss
...What are some things that I can do to troubleshoot this.
-- isolatediguana
without having proper knowledge i had been messing around with hissing noise in audio equipment every now and then.
in some cases the direction of the AC power plug solved my issue.
in other cases i figured out that a totally different device (e.g. some light) had been the cause
sometimes an additional wire (ground to ground) solved my problem.
further you can try to narrow down the cause by unplugging all modules in both cases and replug+check them one by one.
good luck!
