The Adastra A2 is a high quality amplifier that'll comfortably power your speakers. We've bundled the A2 with the popular Q Acoustics ceiling speakers to create a high quality yet cost-effective ceiling speaker system.

An inbuilt media player section offers playback of mp3 audio tracks from USB drive or SD card and also has a Bluetooth receiver and FM radio tuner.

A rotary switch selects between 2 rear stereo inputs, a front 3.5mm stereo input or the built-in media player.

Speaker connections on the rear panel are via 4mm binding posts, which can drive up to 2 x 8 Ohm speakers per channel to deliver 2 x 100W.
