Unitex Mixer Amplifier, 80 W, Black, USSA-80EU

The Unitex USSA-80EU is a professional public address mixer amplifier that delivers 80 W RMS, with a maximum output of 110 W, into either 100 V and 70 V constant-voltage lines or conventional 4, 8 and 16 ohm speakers. Four balanced microphone inputs with an echo control let an imam, teacher or shop announcer speak clearly over background music fed from Bluetooth, USB, MicroSD or the built-in FM tuner. It is widely installed in mosques, schools, small factories, supermarkets, clinics and meeting halls, where its 100 V line output allows dozens of ceiling or horn speakers to be daisy-chained over long cable runs with almost no loss. The unit runs from 220–240 V AC mains and accepts a 12 V DC battery input for uninterrupted announcements. It weighs about 8.5 kg and has bass and treble controls to tune the sound to the room.
