Re: [emax] Stereo sample phase reversal?

2009-08-29 by Tristan

Hello Daniel,

I would say the output of your soundcard is balanced TRS, where the
tip and ring carry the same mono signal but with inverted polarity.
However, the Emax II sampling input uses the tip and ring of the TRS
plug as unbalanced left and right signals. So when you sampled in
stereo you were not getting stereo, just normal and inverted mono
signals. If you want to sample in stereo with your present cable then
try plugging into a stereo TRS output like a headphone socket.
Otherwise you will need a Y adapter plugged into the Emax II sampling
input so you can connect it to separate left and right unbalanced mono
signals.

Regards,

Tristan
