Adastra UX240 240W Compact 100V Mixer-Amplifier

The Adastra UX240 is a compact mixer-amplifier for installed public-address and background-music systems. Its 240-watt output can operate with a 100V line speaker system or a suitable low-impedance load down to two ohms, with the mode selected by a rear-panel DIP switch. Screw terminals provide the speaker connection. A combination jack/XLR microphone input has switchable phantom power and an optional voice-operated priority function, while an RCA line input and front-panel 3.5mm auxiliary connection accept external audio sources. The built-in media player selects USB MP3 playback, DAB+ or FM radio, and Bluetooth audio. Master volume, bass and treble controls allow the output to be adjusted for the installation. The rear panel also provides antenna connections and 24V mute contacts for an external trigger. Supplied mounting brackets support paired half-width units in a one-unit 19-inch rack or flat surface mounting. This is an installation mixer-amplifier, not a stereo two-channel touring amplifier; speaker wiring and output mode must match the intended system. No unsupported phantom voltage, dimensions, weight or complete accessory list is claimed.
