Features

1). Equipped with a high quality audio decoder, which supports MP3 and WAV sound formats.

2). Sampling rates supported: 8/11.025/12/16/22.05/24/32/44.1/48(KHz).

3). Built-in 16MBytes SPI flash memory on the board.

4). Load or update sound files via USB connection with computer. No need any any program. The on-board memory will be detected as a USB flash drive on computer.

5). It has 8 trigger ports, and the function of each trigger port can be set individually through a configuration file.

6). Supports 6 type trigger modes. Any trigger port can be set with any of these 6 type trigger modes. 

7). Activated to play back sound using high electrical level or positive pulse signal (from 12V+ to 40V+). 

8). Able to play next track after each activation. Numbers of sound files is not limited with this feature, so long as the total size of the sound files is not larger than 16MBytes.

9). Equipped with a class D mono 15 watts amplifier that can drive a 15 watts siren or speaker directly.

10). Adjustable sound volume through the blue potentiometer.

11). Industrial grade design. Opto-couplers isolation is employed on the circuits to strongly enhance the stability.
