The Adastra RM120-WIFI installation amplifier combines a 5-channel mixer with 120 W of output power for 100 V line speakers or low-impedance speakers. It connects to a wired LAN or 2.4 GHz WiFi network to play internet radio, streaming services or audio from a local NAS drive, and can be configured using the WiiM Home app for Android and iOS. It also supports MP3 playback from USB and wireless audio streaming via Bluetooth 5.0.

The voiceover function automatically lowers the music volume when a signal is detected at the Mic 1 input. The 24 V contacts can mute all inputs except Mic 1, while the separate non-switched output remains active for priority announcements. The unit is designed for 19″ rack mounting.
