Hello James. Welcome to the Golden Records Forum. RecordPad has its own forum. It has been reported in this forum, when using Golden Records, that the best results are obtained by connecting your turntable to an AV receiver and connecting the Behringer, or whatever converter device you have, to the Tape Line Out jacks. Some turntables just don't put out enough "oomph" to record reliably, at least when using Golden Records.
Hope this was of some limited help. Have a great day.
Regards,
-Phil
