This adapter cable - Dual XLR Male to a Gold Plated Female Stereo Mini Jack - will allow you to connect devices 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).
In standard configuration, the adapter supplies +9V across 5.6K ohm resistors to each microphone channel. For "three-wire" lapel-style mics, the adapter is available in a mono configuration, with either a balanced or unbalanced input via minijack or mini-XLR connectors. See this product instead.
