Maybe! The ModMic operates safely at 1-12v, we've tested as high as 12v phantom power, but anything higher will damage your mic.

If your mixer has a 12v setting or outputs 12v or less you are safe to hook up an XLR to 3.5mm adapter.

However, if your mixer or XLR device outputs 48v phantom power, you NEED to use an XLR Power Converter.
