KT0642 is another star product launched by KTMicro after the previous generation VHF-band wireless transmitter chip. It adopts a unique design and patented low power consumption technology. On the basis of improved performance compared with the previous generation product, the power consumption is greatly reduced, and it can be applied to more occasions, especially portable products with strict requirements on power consumption. 
KT0642 also integrates more abundant functions, which can further reduce the overall BOM cost and improve product consistency and reliability. Among them, 15-band audio equalizer designed in the KT0642 allows users to freely and flexibly adjust the audio frequency response to achieve good sound effects. Echo function can make the sound like that in karaoke. 
KT0642 integrates audio AGC and audio ALC functions to improve dynamic range and noise performance, and can effectively adjust and control the frequency offset and bandwidth of the transmitted signal. 
KT0642 optimizes the audio compressor. By co-operating with KT065x series products, KT0642 can effectively optimize the tone tail, distortion and noise floor. 
KT0642 adds the microphone audio signal detection function, which provides a solution for automatic mute and shutdown without audio input.
