How to use

Plug the iRig Mic Cast 2 into the 3.5 mm microphone/headset socket of your smartphone or tablet. Connect headphones to the microphone’s headphone output to monitor audio in real time. Adjust the gain control to set an appropriate input level—start with a low gain and increase as needed to avoid clipping. Position the microphone close to the speaker or subject for clear voice capture; when recording video, align the mic for the chosen camera (front or rear) and verify levels before starting the session. For devices without a combined TRRS port, use a compatible adapter as required by the device manufacturer.

Recommendations

For best results, record in a quiet environment and keep the microphone directed toward the speaker’s mouth at a distance of roughly 10–20 cm. Use the headphone output to monitor for background noise or clipping and reduce gain if distortion appears. When recording outdoors, use a windscreen or shield to minimize wind noise.
