[MAC Computer]
MAC computer does not need to install the driver, just choose to set the corresponding sound output device.
It is recommended to adjust the system volume to the maximum, and adjust the output volume of the machine by adjusting the potentiometer.
When K7 is connected to Mac, it supports up to DSD128 to play DSD tracks. This is because under OSX, it can only support DSD128 through DoP (DSD256 needs to be packaged with 768K under MAC, while K7 supports up to 384kHz ).
In theory, OSX can also connect to K7 to play DSD256 through Native, but the corresponding playback software must also pass MFi and support Native output.
【Linux Computer】
The Linux system is drive-free. In theory, it can be used directly by connecting it to it. However, due to the large number of versions, it cannot be guaranteed that all systems can be adapted. If the connection is not recognized, it is recommended to change to another data cable or USB port for troubleshooting.
