When used with your Apple TV, WiiM Amp Pro and WiiM Ultra support playback of both Dolby Digital Audio (AC-3) and PCM formats, while WiiM Amp supports playback only in PCM format.


There are three options to use your WiiM device with your Apple TV.

  1. Use an HDMI cable to connect the HDMI ARC port on your WiiM device to the HDMI ARC/eARC port on your TV.

  2. Set your TV's audio output to select your WiiM device.
