What is the NanoPlayer unit and what is it used for?

The NanoPlayer Box is a standalone and interactive WAV and MP3 audio file player that uses an SD/SDHC memory card for data storage.

It is primarily used for broadcasting background music, messages, sound effects, or commentary in various environments such as:

• Museums and exhibitions
• Point of Sale (POS) advertising and displays
• Information kiosks and vending machines

Key Features and Uses:

• Autonomous and Automatic Playback: Thanks to its Autoplay function, the player can start broadcasting one or more files as soon as it is powered on. It can also play files in a loop autonomously.
• Interactivity via Triggers: The unit is equipped with a dry contact input (Phoenix terminal block) that allows playback to be triggered by an external event. Various devices such as a push button, an infrared presence detector, or smoke, light, or pressure sensors can be connected to it.
• Versatile Audio Outputs:It offers three types of connections to adapt to different needs:
  • A line output (3.5mm mini-jack) for connecting to an external amplifier or mixing console.
  • An amplified output (via terminal block) for directly connecting speakers, allowing sound coverage for an area of several dozen square meters.
  • Two headphone outputs for individual proximity listening.
• Configuration via Naming: Although it does not have a complex programming interface, the player's behavior (random playback, sequential, retriggerable mode, or not) is entirely determined by how folders and files are named on the SD card.
• Control and Operation: The unit features a volume control button that also serves as a manual trigger button. It can also be controlled by an optional infrared remote control to manage playback, volume, or skipping to the next file.

From a technical standpoint, it supports MP3 files up to 128 kbit/s and WAV files at 16-bit / 44.1 kHz, and requires a 12V DC power supply.
