The microphone can only be used in USB input 1.0 mode, not in Bluetooth, optical fiber, etc; The microphone is not supported in RCA output mode, only in headphone output mode.
Why can't the microphone function be used in USB 2.0 mode?
Because 2.0 supports higher sampling rates, while the sampling rate of the microphone is only 16bit/48khz. When playing high sampling rates such as dsd or 384khz, if the microphone is turned on at the same time, the two will conflict.
Does the 3.5mm audio output interface on K7 support 4-section headphones inserted to use the microphone for calls?
Not supported.
Does the microphone have noise-reduction processing?
Yes, K7 has targeted the ambient noise frequency band and has processed it in an algorithm to make your call clearer.
Microphone mute function.
After turning on the microphone mute function with one click, the other party will not hear any of your voice.
