Micro Player mkIII

The MicroPlayer mkIII is a standalone audio player supporting WAV and MP3 files stored on an SD card or a USB flash drive. Files are played automatically according to an “AutoPlay” setting or a triggering by external events (dry-contact inputs, RS-232 serial commands, etc.).

  • Interactivity:

    • Electrical contacts: 4 configurable inputs that can be combined to trigger the playback of up to 15 folders or to control the playback through sensors, push-buttons, relays, etc.
    • 2 MOSFET switches that allow to control other players and devices.
    • Commands through the RS-232 serial link. A simple protocol is used to send playback and volume commands (management of up to 1000 folders).
    • Infrared sensor usable with a remote control.
    • 2 buttons to which functions can be assigned.

  • AutoPlay: this feature makes it possible to automatically start playback upon power-on. This feature is configurable and can be disabled.

  • Playback behavior: the audio files stored on an SD memory card or a USB flash drive can be organized in a particular way that defines the playback rules with the names assigned to the files and the folders. This smart programming allows a wide flexibility of use.

  • Power supply: the player is protected against polarity reversal and against the use, by mistake, of an alternating-current (AC) power supply instead of the provided direct-current (DC) power supply. The input power supply is transferred to dedicated pluggable terminal blocks to make it easier to power other devices.

  • RS-232 serial link: the player can be controlled by a PLC, a computer, or a remote control using a serial link. The player receives data on its Rx input and sends data on its Tx output.

  • The most common audio formats are supported: WAV and MP3.

  • Flash drive devices: the player allows to manage simply the media content with standard USB flash drives or SD cards.

  • The player offers an all-in-one and cost-effective audio output set with an unbalanced line-level stereo audio output on RCA, an adjustable amplified speaker stereo audio output on pluggable terminal blocks, and a headphone stereo audio output on a standard 3.5 mm jack.
