Description

The Adastra UA30 Compact Mixer-Amplifier is designed for smaller PA installations where space-saving and reliable performance are key. Its half-width 1U design houses a 5-input mixer with three mic/line switchable inputs, an RCA line input, and a 3.5mm aux input. Each input has independent level controls, supported by master volume and tone adjustment for simple operation.

Delivering 30W RMS, the amplifier connects to either 100V line or 8 Ohm speaker systems through secure screw terminal outputs. Channel 1 supports switchable +20V phantom power, making it compatible with condenser microphones for clear and professional speech reinforcement.

Safety is built in with 24V fire alarm mute contacts, ensuring emergency announcements take priority. The UA30 is supplied with hardware for rack-mounting two units together or fixing under a desk or wall. Compact, efficient, and reliable, it is an excellent choice for small shops, offices, classrooms, and reception areas.
