PT2399 Echo Sound Board | Karaoke Microphone Reverb Module | Delay Repeat Echo Control | Low Noise Audio Processor | Preamp DIY Audio Board

Upgrade your audio setup with this PT2399 Echo Sound Board, a high-performance digital echo processor module designed for karaoke systems, microphones, and DIY audio projects. Built using advanced CMOS technology, this board integrates ADC, DAC, and 44K digital memory, ensuring smooth and high-quality echo effects.

It delivers low distortion (THD < 0.5%) and ultra-low noise (No < -90dBV), producing clear, rich, and professional-grade sound output. The onboard VCO (Voltage Controlled Oscillator) allows easy adjustment of echo timing and delay frequency, giving you full control over your sound effects.

With dedicated knobs for Delay, Repeat, and Echo control, you can fine-tune your audio to achieve the perfect reverb effect for karaoke, music, or instruments.

⚠️ Important Note:
This is a pre-amplifier (front tuning board) and does NOT provide direct speaker output. It must be connected to a power amplifier board to function properly.

Perfect for audio enthusiasts looking to build a custom echo system with professional sound quality.
