This adapter cable – Dual XLR Male to a Gold Plated Female Stereo Mini Jack – will allow you to connect microphones with a 1/8″ male output connector to dual XLR inputs with phantom power. With this Y adapter, you can plug mini mics that normally run on “plug in power” into this adapter and plug the adapter into a phantom powered mixer, preamp, etc, and power your mics without the need for a separate battery module. Made in USA. Here is how it works:
This device is an adaptor for plug-in power mics, which enables the mics to be connected to standard professional microphone preamplifiers or digital recorders with phantom powered XLR inputs. The adapter supplies the appropriate voltage to the plug-in power microphones, and provides a balanced, low impedance output to the microphone preamplifier.
The left and right channels of the adapter operate independently, so phantom power must be supplied to both channels for stereo operation. The adapter requires +9V to +48V phantom power to operate (supply voltage to microphones will be reduced with phantom power supply of less than +12V).
The adapter supplies +5V to each microphone channel.

Great adapter! Now I can finally make 32-bit float recordings with my Sound Professionals binaural mics and my LOM Elektrouši, and also use my 3.5mm TSR camera mics with XLR-input recorders. The only gripe I had was that the Left / Right (or channel 1 and 2) plugs are not labeled in any way, you’ll need to test and mark the plugs yourself.
SP tech note: We don’t label them because some 3.5mm plugs are wired differently than others, and this would cause the labeling to be backwards in some cases. It’s better to let the customer label them once they have them.
