J10 HA Series Hearing Aids BLE 5.0 Support exclusive audio transmission protocol, codec format supports CELT, G.722 Deep sleep power consumption as low as 25nA Power supply 1.1v~ 3.3v WDRC to 8 channels noise reduction effect, audio amplification AFC Can be used with TV Companion TV Streamer Can be used with USB Dongle for wireless fitting function The OTC prototype supports display volume "+" is valid, with 7 gear cycles, and the initial boot volume is the first gear with the lowest volume The internal algorithm of the OTC prototype supports a high-pass filter. In the actual application circuit application, a high-pass filter can be added at the back end to filter signals below 800Hz. The reference design will be given in the application manual later. The OTC prototype provides a hearing aid function mode and a TV mode, which can be switched by a button OTC Hearing Aids Support MFi, ASHA Audio Streaming Entertainment Project
