Adastra RMD Series 100V 4 Zone Mixer Amplifier with DAB+, BT, USB/SD

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.
