•Why is the Echo sound so loud when singing with a microphone? How to adjust it?The Echo volume is set to 15 by default. If you find it unsuitable, press the "Menu" button on top of the speaker briefly. When the display shows "E" (Echo), turn the volume knob to adjust the Echo volume.

•Why does the product description mention 400W, but the box says 40W?The speaker's 40W rated power is for continuous use and optimal performance, while the 400W peak power indicates the maximum output during short bursts, like loud bass or dynamic music. Both ratings accurately reflect different performance aspects.
