JamieCrain Posted June 25, 2020 Share Posted June 25, 2020 Hi all I recently acquired a FH1500 and it performs as expected, but have come across an issue. When I adjust the Mid dial on the top of the FH and turn left towards the 9 oclock position, the amp cuts out completely, and the message "Thermal Shutdown" scrolls across the LCD. Sometimes, after a few seconds, the amp comes back to life, sometimes it requires a reboot. It only happens on the Mid dial (so far as I can tell), and at any volume, after any time. So I'm fairly sure it is not actually a heat issue, it's a glitch. I've tried the downgrading the firmware to 1.0 and then back up to 1.3. No change. Anyone seen this before? Any fixes? Is it serious? Quote Link to comment Share on other sites More sharing options...
