The Adastra DM40 40W mixer amplifier features Bluetooth connectivity, a USB input, and an FM tuner. This versatile amplifier is compatible with both 100V line and low impedance speakers. 

The single-zone amplifier features an integrated USB/FM tuner as well as Bluetooth connectivity. This is great for connecting your Smartphone/Tablet or inserting a memory stick with downloaded music on. For shop's and cafe's the USB input can be set to 'loop' meaning the audio will continuously play so you do not have to keep visiting the amp. Play/Pause, Skip track and Mode buttons are also located on the front of the amp.

A 6.5mm microphone input is situated on the face of the amp with its own dedicated volume control. This is great for installs that need to be able to make announcements like last orders, pub quizzes, or just generally getting peoples attention. Other inputs feature AUX and OUT that also have individual volume control's. These inputs can take a direct connection from external devices such as smartphones, media players, and mixers etc.

The DM40 operates both on 4-16ohm and 100V Line.
