KT0655M

Description
KT0655M 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. 
KT0655M 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, KT0655M adds digital audio output, which can directly output digital audio to DSP for sound effect processing. KT0655M adds a Line-In interface, which can input external audio sources into KT0655M for sound effect processing and mix output with the demodulated audio signal of the receiver.
KT0655M optimizes the audio compressor. Co-operating with KT064x series products, KT0655M 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.  
KT0655M integrates howling-sound suppression function, which can effectively improve the occurrence of harsh noise and equipment damage caused by howling.  
KT0655M newly integrates the battery voltage detection and alarm function to meet the user's battery voltage monitoring needs on portable products.  
KT0655M improves product integration, functionality, performance and greatly reduces power consumption so it can meet the more high-end customer user needs.
