Our Adastra MM3260 Mixer-Amp & 70W In-Ceiling Speaker Package is the perfect installation for small restaurants, bars, hotels, offices, and retail spaces that require high-quality music playback and/or public address.

Featuring 4x 70W in-ceiling speakers, the kit is sure to fill your space with excellent audio quality and provides a number of playback options such as Bluetooth, FM Radio, USB as well as RCA Phono inputs for connecting external CD/media players. 

The 4 speaker PA speaker package comes complete with the Adastra MM3260 Mixer-Amplifier, 4 x 5.25" 70W in-ceiling speakers, and 50m of high-quality speaker cable; ideal for background music and public address applications. 


Adastra MM3260 Mixer-Amp

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

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.


Adastra 5.25" 70W In-Ceiling Speakers

A high-grade ceiling speaker featuring a hi-flex polypropylene cone main driver for an extended low-frequency response, and a mylar tweeter unit for accurate HF reproduction.

A flared wave-guide baffle helps to aid dispersion for wider coverage, and a precision 2-way filter network gives accurate high-low separation.

The twist-fit grille enables quick and neat installation resulting in a premium quality sound delivery system.
