Output Devices

To play music via different devices, you can select your desired output device from the My computer/USB speakers/[Media renderer name] (indicating the device you have been streaming music to) drop-down menu on the control bar, and add songs to individual devices.

The output devices include the following:

  • My computer: Stream music to your computer for playback via the speakers of your computer.
  • USB speakers: Play music via the USB speakers connected to the USB port of your Synology NAS, or via external speakers or home stereo equipment connected to the audio dock of Synology Remote (sold separately).
  • Media renderer: Play music via a Digital Media Renderer (DMR) or an AirPlay compatible device within your local area network. Once they are found, their device name will appear in the drop-down menu, like Apple TV, Sonos.


  • Only users with the USB/DLNA Renderer privilege (in Settings > Privileges) can play music through USB devices or DLNA renderers.
  • The output modes for USB speakers and Media renderer are available only when corresponding output devices are found by Audio Station.
  • If you play music via the Optical S/PDIF Output port on the audio dock of Synology Remote, adjust the remote volume to maximum to achieve best audio quality.
  • For more information about Synology Remote, visit

To switch between output devices:

Choose any of them from the drop-down menu at the top of the music player. You can play music via different devices at the same time.

High Quality Output

You can enjoy better audio quality if your music files and the sound card of the DAC (Digital-to-analog converter) connected to your Synology NAS support 24-bit audio output when USB speakers are plugged in to your NAS server.

To enable high quality output or DSD over PCM output:

  1. Go to Settings > Advanced.
  2. Once you have ticked Enable high quality output for USB speakers, you can then tick Enable DSD over PCM (DoP) output for USB speakers.
  3. Click OK.


  1. Only 2-channel DSD64 and DSD128 files are supported if you enable DSD over PCM (DoP) output for USB speakers.
  2. Once you enable DSD over PCM (DoP) output for USB speakers, both DSD64 and DSD128 files will be played via DoP. For example, a DAC that only supports DSD64 cannot play DSD128 files.

Music Transcoders*

Music transcoders allow Audio Station to support more audio formats under streaming. If your web browsers or DLNA devices do not support the audio formats mentioned below, please find the transcoding advice. Also, please note audio files transcoded by Audio Station can only be 16 bit; 24-bit files would be downsampled.

To transcode audio formats for web browsers:

Follow the steps below if your web browsers do not support the formats: FLAC, APE, AAC, OGG, AIFF, WMA.

  1. Go to Settings > Options > Transcoder for Web Browsers.
  2. Choose any of the following options:
    • Transcode to WAV format: WAV format is supported on specific browsers only (Firefox 3.6 and above, Safari 5, Opera 10.60, and Chrome 9).
    • Transcode to MP3 format: By transcoding to MP3, you can enjoy better browser support. However, this also occupies more system resources. In addition to the formats listed above, WAV format will also be transcoded to MP3 when this option is selected.
  3. Click OK.

To transcode audio formats for DLNA devices:

Follow the steps below if your DLNA devices do not support the formats: FLAC/APE, ALAC/AAC, OGG, AIFF.

  4. For better compatibility between your DLNA device and the selected formats, tick Downsample audio files for better DLNA compatibility.
  5. Click OK.
