The Saramonic Blink 500 TX is a remarkably compact and lightweight clip-on wireless microphone transmitter that delivers broadcast quality sound and is designed to work with the Blink 500 RX, RXDi, and RXUC portable dual receivers. The Blink 500 TX has an excellent sounding built-in mic 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 use handheld. The built-in mic 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 mic, providing an even more professional and visually discreet miking solution.
