The Adastra RM120-WIFI installation amplifier combines a 5-channel mixer with built-in audio playback for systems using 100 V line speakers or standard low-impedance speakers. Its output power is 240 W RMS, and its network connection via LAN or WiFi supports streaming from internet radio, streaming services and a local NAS drive, with setup and control through the WiiM Home app for Android or iOS.

The unit plays MP3 files from USB and streams audio via Bluetooth 5.0. The voiceover function automatically lowers the music volume when a signal is detected at the Mic 1 input, while the 24 V contacts can mute all inputs except Mic 1. The speaker outputs include four switchable 100 V zones and one unswitched output for priority announcements.
