microphone cable impedance
microphone cable impedance
I'm getting around to be more serious about making my own cables.
I assume that there is some sort of minimum impedance desired for cable runs that are between 10 and 20 feet long. Can someone please enlighten me on the particulars of that?
Hoping on grabbing some affordable mic cable for all my various studio gear, so it'd be mostly balanced cable for synths and drum machines etc.
Thanks for any thoughts on minimum gauge and/or impedance, conductivity, capacitance, shielding, etc.

I've been using Pro Co Dynamike 224S (24 gauge I think?) for XLR and TRS cables. I don't know the specs very well, but I haven't had any problems with it yet.
As far as I know, braided shields are 90-95% effective, and allow the cable to bend a little more naturally. Foil shields are supposed to be almost completely effective but not as flexible.
I have also been hunting for a good brand of multi-pair snake cable though, as I get more ambitious about re-doing my patchbays. Hopefully someone who replies can suggest something!

I like the Canare Star Quad cables for microphones.

Howling at the neighbors. Hoping they have more mic cables.

I've gotten 20' guitar cables and 20' XLR mic cables at US$10 during sales, and sometimes just on the floor. For some reason they seem to throw the tied circles onto mic stands a lot, literally "on the floor".
Also, if you buy a guitar, etc., they'll often throw in a cable.
I have no problem cutting up and re-ending guitar cables for patch cords for the bay or for FX pedal-boards.

I use Belden 9182 LAN network cable for mics. 150 ohm impedance, 70% propagation delay (70% the speed of light) teflon insulation and 22 AWG wire.
It's 8 pf per foot stray capacitance, very low. Compared to star quad, it's like after your ears pop landing in a jet. I have little or no need to boost the hi end as I don't lose any of it.
Paramount Pictures rewired their entire foley building with it after I brought a few long runs down to evaluate. I use Neutrik connectors with the plastic inserts pounded out to clear the cable diameter.
