How to Use

  2. Turn down the volume on the playback device to a minimum level.
  3. Start music playback.

IMPORTANT: Before beginning music playback, check volume level on playback device and reduce to a minimum level when using PEE51. PEE51 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 PEE51 is connected for the first time and each time
thereafter. Always check the volume level on the playback device before use.
The PEE51 cable should NOT be connected to an Astell& Kern DAP as the volume will be fixed at maximum output when connected and cannot be adjusted on the player or PEE51. Listening to music at maximum volume may cause permanent hearing damage. Astell&Kern is not liable for any damage due to user negligence.

Note

Compatibility

  • The product is compatible with most Android-powered smartphones and tablet PCs, Windows 10 and macOS products, but iOS-operated devices are not supported. Additional manual settings may be required for some Android devices.
  • The PEE51 is not compatible with every Android device. Due to hardware, software and/or system requirements for some Android devices, compatibility issues may occur. Compatibility issues will not be accepted as a reason for exchange, refund or repair.
  • When connected to an Android-powered smartphone or tablet PC, the product can play tracks without any additional driver or application installed.
  • When connecting the PEE51 with a Windows PC for the first time, the computer should recognize the device and the driver should install automatically.

  • Connecting to a playback device using various adapters (USB-A, Micro 5 pin, etc.) may cause an unstable connection and other compatibility issues.
  • The product requires a separate paid/free player to be installed to be able to play DSD and high-quality PCM audio files on a smartphone.
