SE500 Mono Class-D Subwoofer Amp Module

$54.00 USD

2024 Update: Tectonic-D500 will be renamed to "SE500"

SE500 compact amplifier module, specifically designed for subwoofer and rugged - full range PA applications.

Upgrade your amplifier by retrofitting our SE500 module into the power amp section of your busted plate amp or subwoofer amp. Our module is engineered to provide high current output without the aggressive limiters or excessive protections found in other class-D implementations.

The SE500 features a flat wire, high current, low loss ferrite core output filter inductor, guaranteeing optimal performance. Additionally, we've integrated housekeeping supplies, simplifying installation by requiring only the main split power supply. Each SE500 undergoes rigorous testing and quality checks before shipping, ensuring you a fault-free product that you can trust.


Package Includes
1 pc assembled and tested mono module without heatsink.
1pc JST Input connector
5pc Female faston tab

Gain can be further increased by a applying a solder jumper under the PCB.
Clock and mute headers for advanced / multi-channel projects.
