The Adastra UA30 is an ultra-compact & easy-to-use 30W 100V Line mixer-amplifier designed to offer high-quality, dependable service for mobile and installed public address systems.

The Adastra UA30 is a simple and easy-to-use amplifier designed for small to medium-sized venues. It features 5 hard-wired inputs to which you can connect a phone, PC, radio, CD player and other sources. There is no Bluetooth on this unit which makes it a great option for public-facing areas, as it removes the possibility of the system being tampered with remotely.

Located on the front of the Adastra UA30 mixer-amp is a dedicated microphone input (1/4" Jack / XLR) with gain control, and a 3.5mm Jack input. On the rear of the amplifier, there are 3x inputs (2x 1/4" Jack / Phoenix & 1x Phono), and 1x Phono line-output. There is also a 24V fire alarm contact. 

The UA30 comes included with mounting brackets that allow it to be fixed to the underside of a desk/counter or up against the wall.
