Description
This soultion implements a set of 2.4G wireless dual microphones with USB receiver system. It could be used in the professional audio amplifier system or the KaraOK sytem, etc. With TI's ultra-lowpower MCU controler controlling the power supply of the microphone, the battery life is longer. The volume can be manually changed with the key and the power and connection status is indicated with color LEDs.
Features
- High-Performance 2.4 GHz Digital Wireless Stereo Microphones.
- Automatic or manual pairing betweent the microphone and the dongle.
