Description

The Adastra UA90 Compact Mixer-Amplifier is a feature-rich solution for small to medium PA installations requiring flexibility and reliable performance. Built into a half-width 1U chassis, it includes a 5-input mixer with three switchable mic/line channels, an RCA line input, and a 3.5mm aux input. Each channel is controlled from the front panel, along with master output, bass, and treble adjustment.

The UA90 provides mono output to either 100V line or 8 Ohm speakers via screw terminals. Switchable phantom power is available on channel 1, making it suitable for condenser microphones. A class D amplifier with transformer output ensures efficiency, while 24V fire alarm mute contacts guarantee integration into emergency systems.

Supplied with hardware for rack-mounting two units side by side, it offers easy installation in cabinets, walls, or under desks. Designed for versatility and practicality, the UA90 is ideal for schools, offices, retail spaces, and small venues that require clear sound and flexible connectivity.
