Hi I have a DP24SD and Rokit5 powered speakers which have good quality balanced cables. Recently, I’ve experienced an occasional random electrical ‘pop’ sound through both speakers on playback - at least it sounds electrical. It’s unpredictable, meaning that it might not happen at all or perhaps five times over the course of a three minute song. I’ve checked all the settings on the Tascam and tried a different SD card, but to no avail. My equipment is plugged into a surge protector, but I’ve also tried using it without one - but the pop still happens. Can anyone suggest a reason why this is happening - and a potential solution? Thanks !
