The WiiM Vibelink Amp can enter standby mode in three ways to reduce power consumption:

Standby Button: Press the standby button on the device.
Auto-Standby: Automatically enter standby mode after 30 minutes of inactivity.
12V Trigger In: Enters standby when triggered by a connected device.

Note: In standby mode, the WiiM Vibelink Amp's LED indicator dims to half brightness.

For maximum power saving, the WiiM Vibelink Amp can enter sleep mode, dropping power consumption to an ultra-low 0.5 W.

You can manage sleep mode and wake up the WiiM Vibelink Amp in two ways:

WiiM Home App: You can manually put the device into sleep mode and wake it up directly through the app. For details, see How to Manage Your WiiM Vibelink Amp Using the WiiM Home App.
Auto-Sleep via 12V Trigger In: Once entering standby via Trigger In, the device will automatically switch to sleep mode after remaining in standby for 30 minutes. It will also automatically wake up from sleep mode when an active trigger signal is detected.

Note: In sleep mode, the WiiM Vibelink Amp's LED indicator turns off completely.
