Part of the ADECIA series of Dante-networked wireless conferencing components, the Yamaha RM-WGL is a wireless microphone with an adjustable 12" gooseneck, indicator LEDs on the control ring and mic, and a rechargeable battery that can power the mic and transmitter for up to 20 hours, enough time for even the lengthiest discussions. The mic supports the 1.9 GHz DECT standard with 256-bit AES encryption, providing safe and secure transmission at a range up to 164'. The slim gooseneck allows the speaker to position the mic for optimal sound pick up, and the shorter 6" length on this model provides a discreet, low-profile appearance. The cardioid polar pattern provides a 90° angle of acceptance, focusing audio capture on the speaker for less unwanted background sound.
