Hello, everyone,
I'm making cables for various things around the studio and one of them is a nice stereo 1/8" to two (2) male XLR connectors for my Sound Devices Mix-Pre 3 II. I wanted to make the XLRs impedance balanced but I don't know the value of the resistors that is inline with the tip and ring connections on the 1/8" jack on the unit. I emailed the company to find out and they said they didn't have that information and when I pressed further they again said they didn't know, which I thought was weird. On the spec sheet is says that the stereo out impedance is 500 ohms, but I don't know what that means as it applies to what I'm trying to accomplish. To me, that sounds a little high for impedance balancing considering most of what I've seen for accomplishing this task ranges from 47-120R. Can someone break down what a manufacturer is/might be using for the output connection impedance spec?
I know I can just do an unbalanced XLR and call it good, but it's just as easy to add a resistor and have it play nicer with balanced input connections on a console.
Thanks!
Paul
