Hey guys, hope you can help.
I'm getting a high pitched noise from the G90 which gets much more noticeable the more gain is added. I realise all the gain is doing is amplifying the noise which makes the noise more apparent but It shouldn't be there in the first place, the noise is non existent when using a cable. Unfortunately I don't have any other receivers or transmitters to switch out and test. I have tried another cable (guitar to transmitter) and it's still the same, the noise stops when the transmitter is switched off.
Many thanks!
