I am getting audio signal fine through my tuner into amp input ok , but no sound from amp :( this has never happened before.

Hi Dboomer, my new transmitters both work fine with my backup system which I take on travel gigs which is the G55, so that tells me the cables are fine which I knew. So how the blazes does someone upgrade firmware on the G90? if I don't have a XD-v75? I am getting signal level fine using the new transmitters on the G90, but when I play a note on guitar no sound from Marshall head, and tuner doesn't work when I kick the TU1-2 on, obviously something isn't right but I cannot work what? It's not the cables they are brand new, it's not the new transmitters as they work fine with my G55, don't know what else to try.

Hi, I have a Wireless g90 rack system which has worked fine for almost 2 years now, I just bought two new TB12 transmitters, they came set as RF2 which I nkewwouldn't work with my g90 as the firmware isn't v2.0 so I knew I would have to set the new ones to RF1 which I did. I am getting a signal fine on both new transmitters but no signal through my BOSS TU1-2 tuner. Output from Tuner 1/4" is connected to Input on Marshall head, Tuner/Aux out on back of G90 as usual is connected to Input 1/4" on TU1-2, thought maybe the tuner had gone bad so changed it for a 2nd boss, and even my polytune, same thing, no signal from tuner. Tried different instrument cables, still same issue. I am STUCK! have a gig tonight at 9pm so need help badly, don't know what else to try. How do I upgrade the firmware on the G90 rack to newest, so that it supports RF2? there is nothing online how to do this anywhere. very frustrated right now ROD, Sarasota, FL
