Unitex Mixer Amplifier, 30 W, Black, USSA-30U

The Unitex USSA-30U is a professional 100 V line mixer amplifier for public address work, rated at 30 W RMS and able to drive 4, 8 and 16 ohm speakers as well as 70 V and 100 V constant-voltage lines. 3 balanced microphone inputs with echo, an AUX input, Bluetooth, USB, MicroSD and an FM tuner cover every source, and mic priority keeps announcements above the music. Its compact desktop cabinet is the entry point of the USSA range and suits a single small room. It is installed daily in mosques, schools, factories, warehouses and showrooms, where a single pair of wires feeds a long chain of ceiling or horn speakers. Power comes from 220–240 V AC / 50–60 Hz with 12 V DC backup input, and the 60 dB signal-to-noise ratio with bass and treble controls keeps speech clear. Install it on a ventilated shelf and match the speaker tapping.
