1. Description
The DY-HL30F is a DC 12V/24V, 30W Mono Voice Playback Module designed to be triggered by 9 input signals. It functions as a one-on-one segmented trigger control player, supporting both MP3 and WAV decoding formats. The module utilizes a low-level trigger mechanism and operates on a wide voltage range of 9-24VDC. It can directly drive a 4-8 ohm speaker with a maximum output power of 30W. The module features built-in 64Mbit (8MByte) flash storage, allowing audio files to be replaced via a USB data cable connection to a computer. It also includes volume adjustment capabilities and can be connected to external warning lights. Multiple triggering working modes can be configured, making it suitable for various applications.

6. Notes
- This module uses a low-level trigger; the input port accepts a GND signal.
- The module must be restarted after changing work modes.
- For the 'Inter-Cut Trigger' mode, background music is stored in the root directory, and triggered music files must be in the 'CHABO' folder. The 'CHABO' folder is not required for other play modes.
- Music file names must be 5-digit numbers (e.g., 00001.mp3, 00009.mp3).
- Each input port controls a specific music file (e.g., S3 controls 00003.mp3).
- Use a USB data cable for computer connection; a USB power cable will not be recognized.
7. Applications
- Speaker modification, repair, or replacement.
- Amplifier equipment for training or activity sites.
- Car Bluetooth devices.
- Music festivals and parties.
- Family entertainment and leisure.
- Games and cinema sound systems.
