The 512 uses a lithium-ion battery.

There is a cardboard insert located in the 512 box containing the manual and the micro-USB charging cable.

There can be only 1 active pairing at a time.

The DAC3 uses the ES9281A PRO DAC chipset

The DAC3 only needs 200mA USB power to work, which most all modern source devices are capable of.

Verify that the audio cable from the D3 is plugged in and in working order.
Verify that the sample rate selection in your computer's OS is set correctly. Your OS's output settings will determine the color of the LED on the DAC3 -- not the specific file being played.

Check the cables between DAC3 and your headphones or sound system. Also check your audio player and OS audio controls to ensure that the audio balance is centered as well.

Please check that the volume control on your phone/tablet/computer is up and at a good level; 75% should be a good level. Also try adjusting the volume on the DAC3 as well.

  1. Verify that one of the included cables is completely plugged into the DAC3 and your source device.
  2. Also verify that a 3.5mm mini-jack is firmly plugged in.
  3. Try disconnecting and reconnecting both the USB and 3.5mm cable.
  4. You will see an LED light confirming the DAC3 is getting power and is connected to an output.
  5. Check the volume level on your source.
  6. If connected to a computer, verify that the DAC3 is recognized and the active output device.
  7. Try restarting your computer.

If none of the above helps resolve your issue, please contact our Support Team for additional assistance.
