Description
KT0653D 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.
KT0653D 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. KT0653D adds a Line-In interface, which can input external audio sources into KT0653D for sound effect processing and mix output with the demodulated audio signal of the receiver.
KT0653D optimizes the audio compressor. Co-operating with KT064x series products, KT0653D can effectively optimize the tone tail, distortion and noise floor.
KT0653D integrates howling-sound suppression function, which can effectively improve the occurrence of harsh noise and equipment damage caused by howling.
KT0653D newly integrates the battery voltage detection and alarm function to meet the user's battery voltage monitoring needs on portable products.
KT0653D no longer needs an external EEPROM to configure the chip, and directly integrates the configuration information of the OTP/MTP memory chip, which can help customers apply to smaller products while reducing costs.
