There are various colors of the lights on the C-1/U microphones. These lights do not change when lighting up. There are two versions of the C-1, the C-1U USB and the standard slr C-1, which requires a preamp and phantom power.
The C-1U is a USB powered condenser cardiod microphone and is designed for close micing recording or podcasting. The ideal distance from the sound source should be between 4 - 10 cms. Please ensure you record from a close distance and the sound source is at a reasonable sound level.
A pre-amp cannot be fitted to the C-1U mic as it is powered via USB.
After installing the C-1U driver, you will set the input to be Behringer USB Audio inside the preferences of your recording software.
