KT0656M

Description
KT0656M is another star product launched by KTMicro after the previous generation of wireless microphones. It adopts a unique design and patented low-energy technology, less energy cost and performs better than the previous generation. It can be applied to more occasions, especially portable products that require strict power consumption. 
KT0656M integrates more functions, which can further help users reduce PCB area, improve product reliability and consistency, and make production easier. Equalizer, exciter, and Echo can improve sound quality on some occasions and help customers design better products. While retaining the previous-generation analog audio output interface, KT0656M adds digital audio output, which can directly output digital audio to DSP for sound effect processing.
KT0656M optimizes the audio compressor. Co-operating with KT064x series products, KT0656M can effectively optimize the tone tail, distortion and noise floor.  
The true diversity function is also a highlight of this generation of products. On the basis of a small increase in cost, users can easily realize the true diversity function, which greatly improves the transmission and reception distance.  
KT0656M integrates howling-sound suppression function, which can effectively improve the occurrence of harsh noise and equipment damage caused by howling.  
KT0656M newly integrates the battery voltage detection and alarm function to meet the user's battery voltage monitoring needs on portable products.  
KT0656M improves product integration, functionality, performance and greatly reduces power consumption so it can meet the more high-end customer user needs.
