The WiiM Amp features three distinct audio input interfaces: the analog LINE IN, the digital optical (TOSLINK) SPDIF IN, and HDMI ARC. Connect a wide range of devices such as CD players, TVs, PCs, or turntables, to your WiiM Amp for high-quality playback.
Both the SPDIF-In and HDMI ARC support an impressive audio quality of up to 192kHz/24bit, ensuring premium sound delivery.
How to play audio from external devices:
- Open the WiiM Home App and select the 'Device' tab.
- Choose the device or group where you want the audio to play.
- Go to the 'Browse' tab, scroll down, and select the appropriate input option: HDMI ARC, Line-In, or SPDIF-In.
Enjoy exploring these features to elevate your audio experience with both ease and versatility.
Supported Audio Format for HDMI ARC and Optical Input:
The HDMI ARC and optical input port on the WiiM Amp are tailored for stereo PCM audio. It does not support other TV audio formats like Dolby Digital, Dolby Atmos, or DTS.
To ensure compatibility and proper sound output, select PCM as the audio format on your TV or Blu-ray player settings.
Important notes on HDMI port:
1. To connect your TV to the WiiM Amp using an HDMI cable, please select HDMI port on your TV or BD player marked as ‘HDMI ARC’. Please note that connecting to other HDMI ports will not transmit sound to the WiiM Amp.
2. If you experience no sound after connecting the WiiM Amp to your TV via the HDMI ARC port, ensure that the HDMI ARC output on your TV is activated.
3. Should you encounter issues with your TV not controlling the Wiim Amp or the WiiM Amp not controlling your TV, verify that the HDMI-CEC control on your TV is enabled. 4. If your TV doesn’t have an HDMI ARC port, you'll need to connect to your TV’s optical digital OUT port with the optical input port of the WiiM Amp.
Enabling Auto-Sensing for Audio Input:
Auto-sensing allows the WiiM Amp to automatically play audio from the connected input as soon as a signal is detected, regardless of the device's current state or standby mode.
Steps to Activate Auto-Sensing:
- In the WiiM Home App, navigate to the 'Device' tab.
- Tap on the gear icon to access device settings.
- Select 'Audio Input' and activate 'Auto Sensing' (Note: This feature is disabled by default).
By enabling Auto-sensing, your WiiM Amp will seamlessly transition to input audio, enhancing your listening experience with convenience.
*Note:
When the auto-sensing feature is enabled on the WiiM device and it is streaming music from a Wi-Fi source, the feature will be inactive if any of the following inputs - Aux-in, Line-in, Optical-in, or HDMI - are simultaneously playing music. To engage the auto-sense feature and switch to one of these inputs, the current source signal must be paused for a minimum of 17 seconds. Following this pause, a continuous signal from the desired input source for over 3 seconds is required for the device to switch to that input mode.
