11.What are the 8 working modes supported by K17?

The K17 has 8 working modes, explained as follows:

(1) USB: USB decoding, connect to mobile phones or computers. If the two USB ports on the front and rear panels are connected, the front one will prevail, and the rear one will be disabled. When connecting to a mobile phone, the K17 will not consume its power.

(Note: You would need to install the USB DAC driver when connecting the K17 to a Windows computer for USB decoding. Please download the USB DAC driver on our website and follow relevant instructions to install it. For macOS, it runs driver-free.)

(2) OPTICAL: Optical decoding, connect to devices with an optical output.

(3) COAXIAL: Coaxial decoding, connect to devices with a coaxial output.

(4) Line IN: Single-ended line input mode, connect analog signals of the front end to the LINE IN port on the back of the K17 for amplification.

(5) Balanced IN: Balanced line input mode, connect analog signals of the front end to the 4.4mm LINE IN port on the back of the K17 for amplification.

(6) BLUETOOTH: Bluetooth decoding, connect to devices that support Bluetooth output. When switched to the Bluetooth receiving mode for the first time, the K17 will automatically enter the pairing state. At this time, the screen of the K17 will display “Pairing...”. In later uses when entering the Bluetooth receiving mode, the K17 will automatically reconnect to the last-connected device.

(Note: The Bluetooth mode of the K17 only supports audio playback, but not voice calls.)

(7) Streaming: Streaming media receiving mode, connect the K17 to the network, supporting devices under the same LAN to play music through AirPlay or Roon.

(8) Local playback: Local playback mode, insert a USB flash disk into the USB-A port on the back of the K17 to scan and play the songs inside.
