The LIONBEAM lb-wifiamp-2 is a stereo Class-D in-wall WiFi audio amplifier rated at 45 watts total output, delivering 25 watts RMS per channel. Designed for permanent in-wall installation, it accepts wireless audio streaming over WiFi and includes a wired AUX input for direct device connection. Operating on 24 volts DC, the unit runs a Class-D amplifier stage, which keeps heat generation low and makes it well-suited for enclosed wall-cavity mounting. Licensed contractors and low-voltage audio installers handle this type of installation in both residential and light commercial settings.
The lb-wifiamp-2 is intended for in-wall audio distribution in residential or light commercial environments where a clean, flush-mounted amplifier installation is required. It supports wireless streaming through the 4STREAM and MUZO apps, making it compatible with multiroom audio setups that use those platforms. The AUX input allows a locally connected source device to play through the unit when wireless streaming is not needed. Minimum speaker load resistance is 4 ohms, which covers most standard in-wall and in-ceiling speaker pairs used in distributed audio systems.
Compatible with the 4STREAM and MUZO audio apps and supports Spotify playback. Designed for use with speaker loads rated at 4 ohms or higher.
Installation should be performed by a licensed low-voltage or electrical contractor in accordance with NEC Article 725 and any applicable local codes for in-wall audio equipment. De-energize all circuits in the work area before beginning rough-in or wire termination. Verify that the 24-volt DC power supply is correctly rated for the unit before connecting. Do not enclose the unit in an airtight cavity without confirming adequate thermal clearance per the manufacturer guidelines.
