How to Use

  1. Connect the AK HC2 to the playback device (Smartphone, tablet PC, or computer) and ensure the white LED light is on.
  2. Turn down the volume on the playback device to a minimum level.
  3. Start music playback.
  4. 4mm Headphone Port (Not compatible with microphones and in-line controllers) USB Type-C Plug

IMPORTANT: Before beginning music playback, check the volume level on the playback device and reduce to a minimum level when using AK HC2. AK HC2 has a built-in amplifier making the sound output more significant than other devices at the same sound output level. It is important to start at a low volume level to protect your hearing. Depending on the playback device you are connecting to, the volume will default to the maximum output level when the AK HC2 is connected for the first time and each time thereafter. Always check the volume level on the playback device before use. The AK HC2 cable should NOT be connected to an Astell& Kern DAP as the volume will be fixed at the maximum output when connected and cannot be adjusted on the player or AK HC2. Use with the maximum volume may severely damage hearing. Astell&Kern is not liable for any damage due to user negligence. Be sure to check the volume first when using.
