The Ultra Audio Streamer is also equipped with an Ethernet RJ-45 LAN jack (10/100Mbps) for a wired network connection to your router. By connecting the WiiM Ultra Audio Streamer to your network and ISP, you get access to a variety of online music services and internet radio from the WiiM Home App, Amazon Alexa, and Google Cast; as well as DLNA compatibility and Roon-Ready certification (coming soon).

ESS ES9038 Q2M DAC: The WiiM Ultra Audio Streamer features a premium ESS ES9038 Q2M DAC (digital-to-analog converter) for Hi-Res sound quality with high 121db SNR (signal-to-noise ratio) and ultra-low 0.00018% THD (total harmonic distortion). Its capable of playing back 2ch stereo Hi-Res music files up to 32-bit/384kHz stereo PCM.

Auto Calibration: The WiiM Ultra Audio Streamer's connected amp, receiver, or speaker may have different audio path latency due to different hardware, software and DSP processing. To maintain audio synchronization of each component, WiiM incorporates auto calibration. By leveraging a built-in microphone and proprietary algorithm, the entire audio path latency is measured automatically when the WiiM is connected with your integrated amplifier, AV receiver, or powered speaker. The latency value will be used to maintain the perfect audio synchronization in wireless multi-room or multi-channel playback.

Advanced EQ: When adaptive EQ is enabled, the music genre information and other tags included in the audio content are used to adjust the frequency of the WiiM Ultra Audio Streamer in real-time by bringing in rich audio to capture every musical detail or make vocals clearer. You can also further cater to your listening taste by applying multiple EQ options including 24 EQ Presets, Bass & Treble adjustment, a 10-band Graphic EQ or Parametric EQ.

Linkplay: Using Linkplay protocol, the WiiM Ultra Audio Streamer can be configured in a multi-room application with other WiiM and Linkplay devices, or can be paired with another Ultra Audio Streamer in a stereo configuration. Using proprietary hardware, algorithm, and software optimization, WiiM can achieve less than 150uS (0.00015s) synchronization accuracy among connected devices as long as all your compatible devices are on the same wireless WiFi network.

• Multi-Room Audio: Using the WiiM Home App (for Apple iOS or Android OS) you can create a multi-room audio experience by wirelessly linking multiple WiiM and Linkplay devices together in different rooms of your house. You can choose to play the same audio content on all your devices or a group of devices, or play a different music source on each WiiM or Linkplay device in your home. Multiroom compatible sources include Network content, Bluetooth sources, as well as analog & digital inputs. You can also control the volume globally, by group, or for each device.
• Stereo Pairing: If you have two separate powered speakers, you can use two WiiM Ultra Audio Streamers to create a stereo pair by connecting one Ultra Audio Streamer to each powered speaker. Use the WiiM Home App to setup Stereo Pairing between two Ultra Audio Streamers and then designate which one is the Left channel and which one is the Right channel.

Gapless Playback: Precise gapless playback is important to many user's listening experience when listening to live concert recording. With precise gapless playback, the playback timing is guaranteed to be identical to the source. Whereas some software, firmware, and hardware components may add substantial delay associated with starting the playback of a track, WiiM uses two decoders to remove the extra samples at the beginning and end of each file and combines them. As a result, here are no gaps or overlaps (crossfading) between successive tracks. This works for all the supported music services and music on your smartphone, tablet, and local network.

HDMI ARC: The WiiM Ultra provides an HDMI ARC jack so you can connect the unit to the HDMI ARC jack of your TV, allowing you to listen to your favorite TV shows, movies, sports, and games through the WiiM Ultra and your connected speakers.
