The TX9 and RX9 from Saramonic are a transmitter and receiver set from the UwMic9 system. The TX9 transmitter and two-channel RX9 receiver are easy to connect, because of the built-in infrared module, an automatic scan or on manual mode. With the TX9 comes a lavalier microphone, also named lapel microphone. You attach the microphone with a small clamp onto the tie or shirt of the person you want to interview. The included TX9 transmitter can be attached to the pocket, with one of the included clamps. The person you want to interview is now able to move freely, without worrying about a cable that’s connected to the camera.
