Description

The Adastra UM90 Compact Mixer-Amplifier combines digital playback with efficient 100V amplification in a slim, ultra-compact format. Featuring an integrated USB/FM/BT audio player, it allows music streaming and playback without additional equipment. Bluetooth connectivity includes a programmable ID for secure pairing, making it ideal for commercial installations.

Inputs include a microphone, RCA line input, and a 3.5mm aux input, all with dedicated controls alongside master volume adjustment. Mono output can feed either 100V line or 8 Ohm speaker systems, connected via screw terminals. The efficient class D amplifier delivers 90W RMS, with support for DC backup power via 24V terminals for added reliability.

Additional features include 24V fire alarm mute contacts for safety integration and supplied hardware for mounting two units side by side in a 1U rack space. Compact yet powerful, the UM90 is designed for small to medium PA systems in retail, hospitality, and corporate environments.
