kutabare Posted November 14, 2020 Share Posted November 14, 2020 (edited) One of my TTM57SL mixers has started to die. If powered off for a while it will work and then after an arbitrary time it will die. When dead the only thing that works is the mic LED when that's turned on. Everything else is dead, no audio, no LED on the USB port, no audio bumps on the headphones when togging the power switch. It needs to de powered for a good day or so before it will work again and then it will only work for an hour or so. I thought the PSU may be flaky but the test points on the PCBs give good reading for +3.3, +5 and ±9volts. Any ideas/suggestions as to what's wrong? Alternatively, is there someone UK based that could check it out? Thanks Edited November 15, 2020 by kutabare Quote Link to comment Share on other sites More sharing options...

kutabare Posted December 7, 2020 Author Share Posted December 7, 2020 Quick update. I realised I was using 250Ω Beyerdynamic headphones with the 57. I swapped them out for a 32Ω pair and haven't had any issues since. 1 Quote Link to comment Share on other sites More sharing options...
