Audio issues on channel A of (parisian producer) #MarlonB 's DMX15-80S solved: no more distortion! 👌 . This was actually due to an unintentional electrical bridge on the solder side of the unit's motherboard, between a loooong jumper wire and some solder joint on the PCB... this very wire, bringing one of the sampling frequency signals to Channel A's DAC3 board, was so much disturbed by the electrical short that the output of the converter added a lot of harmonics... . Anyway, now on to the few issues left: some glitches still occur due to one of the ribbon cables gone brittle. Last, a global check for all the remaining functions will be on order, naturally ;-) . #AMSNeve #AdvancedMusicSystems #AdvancedMusicSystemsLtd #AdvancedMusicSystemsBurnley #DMX1580 #DMX1580S #AMSDMX1580S #VintageDigitalFXBox #VintagePitchShifter #VintageDigitalDelayLine #Repair #Fix #VintageElectronics #EarlyDigital #MarlonBParis #StudioMagnetica #StudioMagneticaParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager
