Adastra RM120B Mixer Amplifier Bluetooth

The Adastra RM-120D is a 5-channel 19″ rack-mountable mixer-amplifier, tailored to commercial sound installations to power 100V line speakers or standard speakers down to a 4 Ohm load. Input options include XLR (with switchable phantom power), mic/line jack, and RCA line. Features an inbuilt DAB+/FM radio tuner, front-mounted SD/USB ports, and Bluetooth® connectivity, all controlled via an integrated media player for hassle-free playback.
