Product Introduction
The PT2399 Reverb Board is a reverb module that uses the PT2399 chip to generate analog reverb via delay. For proper operation, the recommended connection order is: Microphone → Microphone Preamplifier → Microphone Reverb Board (this module) → Power Amplifier. Therefore, to use this module, you usually need to pair it with additional components like a microphone preamplifier; otherwise, the effect will not work properly.
Electrical Parameters of the Reverb Board
Operating voltage: DC 6-15V

Notes
R27 is the resistor for adjusting reverb depth. If you need to modify the depth:
1.Remove R27.
2.Solder a potentiometer (20kΩ or 50kΩ recommended) to the S–G–G pads for adjustment.
Wiring Instructions
Usage Instructions
- Adjust the reverb effect using the potentiometer.
- Follow this connection order: Microphone → Microphone Preamplifier → Microphone Reverb Board (this module) → Power Amplifier.
