Built-in Microphone & Lavalier for Blink 500 Receivers

The Saramonic Blink 500 TX is a remarkably compact and lightweight clip-on wireless microphone transmitter with built-in microphone & lavalier that delivers broadcast quality sound and is designed to work with the Blink 500 RX, RXDi, and RXUC portable dual-receivers.

The Saramonic Blink 500 TX has an excellent sounding built-in microphone and the entire device is small and light enough to clip directly to shirt collars, clothing or slide into a pocket. It is also versatile enough to set on a table or podium, or even used handheld.

The built-in microphone is capable of capturing voices clearly and naturally, but if you want an even cleaner visual look, it also operates as a traditional bodypack transmitter with the included SR-M1 professional omnidirectional clip-on lavalier microphone, providing an even more professional and visually discreet miking solution.

The item includes 1 clip-on wireless transmitter with a built-in microphone and a built-in clip, 1 SR-M1 omnidirectional clip-on lavalier microphone and windscreen.

Does not work as a stand alone unit. Requires Saramonic Blink 500 Wireless Receiver which supports up to two simultaneous transmitters.  Blink 500 Receiver for CamerasiPhones and Android Smartphones.
