Outdoor PA System Overview

Adastra DM25 25W 100V Mixer Amplifier

The Adastra DM25 is 25W Mixer Amplifier that is a perfect install into ANY small venue such as a cafe, shop, office or into a home environment. 

The single-zone amplifier features a integrated USB/FM tuner aswell 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/PauseSkip 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 it's 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 direct connection from external devices such as smartphones, media players, and mixers etc. 

The DM25 operates both on 4-16ohm and 100V Line. Here at Secure360 we strongly recommend using the amplifier in sync with the 100V/8ohm speaker range.
