The Adastra MM3260 is a 1U rack-mountable mixer-amp with a built-in media player and Bluetooth receiver.

This 2 x 60W mixer amplifier from Adastra is perfect for standalone background music systems in local areas or can be connected onto further amplifiers for larger installations. 

The MM3260 features 3 switchable mono inputs via XLR microphone or line-level input; perfect for connecting external audio devices such as smartphones, laptops and PC's as well as microphones. 

Each of these inputs has switchable +20V phantom power for use with condenser microphones or D.I. boxes and channel 1 has a variable priority function which will dim/mute any other input when a signal is picked up. This is ideal for applications needing to make announcements loud and clear. 

The built-in media player operating modes include 3.5mm Aux input, USB audio player, FM radio tuner and Bluetooth receiver for playback from a smartphone or tablet. Also has a front facing 3.5mm Aux input great for easy connection. 

Features 24V emergency mute contacts for connecting a fire alarm system. When a signal is picked up from the fire alarm, the amplifier will be muted ensuring a loud and clear alarm can be sounded. 

Main left and right speaker outputs are connected via Euroblock style screw terminals and the line signal is fed to L+R XLR outputs. This enables a balanced output to be fed to an additional power amplifier or even an active subwoofer.
