Nostromo Posted March 31, 2015 Share Posted March 31, 2015 Hi, Can anyone confirm if its ok to connect a balanced output preamp to an unbalanced input power amp ? My preamp has a balanced XLR output and the power amp has an umbalanced mono jack input. Any thoughts on if its possible to connect them together and where I might get a lead ? Thanks, Quote Link to comment Share on other sites More sharing options...
bigjohn Posted March 31, 2015 Share Posted March 31, 2015 I connect an unbalanced mono jack output to a balanced XLR input on my power amp. I cant see there being a problem. I bought a bespoke cable from OBBM. Quote Link to comment Share on other sites More sharing options...

Nostromo Posted March 31, 2015 Author Share Posted March 31, 2015 Thanks for the link . . . Very helpful . . . . I just need to pluck up the courage to choose a connection method ? . . . . I have no idea whether I should incorporate the neg to earth link in the XLR end of my connector cable ???? Quote Link to comment Share on other sites More sharing options...
