banneduser Posted March 28, 2004 Posted March 28, 2004 When switching on my MIDI-Box, the power supply starts buzzing (around 1kHz), and with every LED turned on or off the buzzing changes. Is it possible, that this is because of an defect in the voltage converter?
TK. Posted March 29, 2004 Posted March 29, 2004 Hi,are you using a switched power supply, or a common transformer?Best Regards, Thorstem.
