First Arduino project..wireless microphone system with NRF24L01

Hello there,
Was wondering how I can attach a handheld hi-z microphone into a arduino-powered nrf24 (designated as a transmitter) and have another arduino as the reciever will be connected to an amplifier. Therefore in theory this will give me wireless communication.

I've only found codes that deal with powering motors wirelessly but nothing that can transmit the small voltages that a microphone might produce.

Any help would be much appreciated.
