SexyBeast Posted March 5, 2005 Report Share Posted March 5, 2005 Hi,I've got a problem with my new opl3 module. In fact it works, but I get a strange, distorted sound (sounds as if the gain was too high). I got only one YAC512 stuffed, and both channels sound the same.I checked and double checked for short circuits - nothing found. I changed the TL074 chips - no effect.What can I do? Any hints welcome.regards, tom Quote Link to comment Share on other sites More sharing options...
TK. Posted March 6, 2005 Report Share Posted March 6, 2005 Hi Tom,could it be that you forgot the 22k feedback resistors at IC6 (R6/R9/R12/R15).If this isn't the reason, check the audio signal before the output amplifier (e.g., at pin 8 and 14 of IC3) - just connect it directly with your soundcard/mixer input (don't forget the ground connection)Best Regards, Thorsten.
