MicroPlayer features

Interactivity

The MicroPlayer mkIII is an interactive player. It reacts based on events:

• Playback behavior defined by folder or file names.
• Electrical contacts: 4 combinable inputs for up to 15 possibilities to trigger files via sensors, push buttons, relays, etc.
• 2 outputs can control LEDs, relays, motors, or any other external systems using MOSFET transistors capable of switching up to 500mA.
• Commands via RS-232 serial connection. A simple protocol is used to send commands to the player.
• An infrared sensor is included in the player to control it remotely via a remote control.

Autoplay Function

The MicroPlayer mkIII features the Autoplay function. This means that at power-up, the player can automatically play one or more files. This function is configurable and can be disabled.

Playback Behavior

Files stored on the storage media (SD/SDHC, USB drive, etc.) can be organized in a specific way to define playback behavior. File and folder names define the playback behavior, giving the player great flexibility in use.

Audio Output

2 types of outputs are available:

• A stereo line-level audio output via standard RCA connector.
• An amplified stereo output via detachable terminal block.

Power Supply

The player is powered by an external power supply providing 12V. The player is protected against polarity reversal and against the accidental use of an AC power supply instead of the provided DC power supply.

Note: The player can accept a power supply voltage tolerance between 10V and 15V. Outside this voltage range, the player may be damaged.

The input power supply is routed to the RS-232 connector and the output terminal block to power connected accessories.

The power supply capacity determines the output power of the amplifier. For line-level output use, a 500mA (6W) power supply is sufficient to operate the player.

For high-power use of the amplifier output, a power supply of at least 3.45A (45W) is essential. If you use an insufficient power supply, you risk getting very poor sound quality and overheating the power supply to the point of failure.

RS-232 Serial Connection

The MicroPlayer mkIII can be controlled by an automation system, computer, or remote control using a serial connection. The MicroPlayer mkIII receives information on its Rx input and sends information on the Tx output.
