Flagship of the Waves System range, the MicroPlayer mkIII+ is a professional audio solution designed to fulfill to a wide scope of playback scenarios.
On switching on the player, the playback is performed precisely and offers among others a loop playback.

Backed on the interactivity skills of the MicroPlayermkIII , the playback can be controlled with motion sensor, push buttons or an RS-232 link. Its 2 outs are able to control leds, relays or machinery.

Its energy saving mode allows an outdoor installation with solar panels or batteries.

Its built-in amplifier and headphone out ease your installations. With a small size and without any risk of heat, the MicroPlayer mkIII can be installed in a storage array or directly within your productions.

A reliable technology

An inventive content struture system shapes the playback thanks to the use of a simple file manager in order to name the files and folders . Many options are available for your applications from the more simple to the more complex.
