dicovish Posted April 10, 2009 Share Posted April 10, 2009 Hi All, I really should know the answer to this but can I just check with you all, when wiring a keyboard into an active DI box, should I use 2x balanced (stereo) or 2x unbalanced (mono) jack leads? The only reason I ask is because some keyboards I have come across have line outs with an L+R and R on them which makes me think its expecting a balanced jack in the L+R socket and an unbalanced in the R socket? Thanks in advance for your thoughts. David. Link to comment Share on other sites More sharing options...
paulears Posted April 10, 2009 Share Posted April 10, 2009 hardly any keyboards have balanced outputs - use a two circuit jack (tip and sleeve) and all will be well. A stereo keyboard uses two unbalanced outputs. The confusion arises from thinking that balanced=stereo. A 3 circuit jack with a ring, is usually mono, balanced. Headphones are stereo, unbalanced - and this kind of connection is pretty rare on keyboards. The L and L/L+R connection is just arranged with switching contacts, so if the keyboard detects you only have one cable in, it sums the L+R channels, if you stick in two jacks, then you get the left and right split needed. Nothing to do at all with balanced. Link to comment Share on other sites More sharing options...
Pyramid Posted April 10, 2009 Share Posted April 10, 2009 Agreed. L+R labelling on a socket is ambiguous as could imply as the OP asks, do L+R come out of one socket, separately? A clearer and more accurate way of labelling used by some manufacturers is L/mono and R. Andy Link to comment Share on other sites More sharing options...
