Adastra RM240D Mixer-amp 100V BT/DAB+

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. A switchable ‘voiceover’ feature automatically lowers the background music volume when a signal is detected via mic input 1, and rear panel 24V contacts can mute all except mic input 1 when triggered. Outputs on screw terminal are via 4 switchable zones with a separate "always on" output for priority alert speakers.
