I am currently trying to read up on this subject. My audio interface accepts either balanced or unbalanced 1/4" jacks into its inputs, and out of its outputs. I am going to a remote session where they are using a bass preamp that will generate line level signals out of two unbalanced 1/4" outputs, for stereo operation. I could simply use TS cables and be fine, however - I am curious if using an adapter to take the cable from TS output to TRS input would help the noise issue. Or is that only necessary if my inputs were balanced only? I have read that you shouldn't use a balanced cable from an unbalanced output to a balanced input, in Mike Seniors "Recording Secrets" book.
