How to use the K7 as a USB DAC for mobile phones:

For Android phones: - Set the K7 input to USB mode - Set the K7 output to the corresponding output port: [PO] for headphone out on the front panel, [PRE] or [LO] for line-out on the rear panel - Connect the phone and K7 with a USB C to USB B data cable - If there is no sound, check mobile phone playback software settings, USB debugging, and cable compatibility

For iPhone/iPad: - Purchase a Lightning to USB B data cable with OTG function - Connect K7 and iPhone/iPad/iPod to enjoy high-quality music
