AT2022 - Extended cable length with standard xlr mic cable?
Your AT2022 mic is supplied with what looks like a standard xlr mic connector to a 1/8" stereo connector, presumably for use with a camcorder stereo mic input. Can I add a 50' lo-z standard mic cable to use the mic remotely from my camcorder?
I actually use this mic along with a Canon HD camcorder with a 1/8" trs input and a 50 foot standard XLR cable for extension. Here is what I found related to EMI (and note, it took awhile to troubleshoot this issue).
If I plug the mic into a 50 foot XLR cable, then to the XLR-to-1/8" trs adapter, and into the camera, AND run the camera solely on battery without the AC power adapter AND without connecting to an external monitor, I can run 50 feet without EMI issues.
However, if I make any connections to any plug that is separately powered--be it the included AC adapter, or an HDMI monitor (with its own power source)--then I get noticeable EMI in the audio. Plugging in headphones is fine because they do not have a power source.
