From the project
A KiCAD project for the TPA3255 amplifier in PBTL mode
This repository contains schematics, PCB layout and documentation for a compact, rack mountable PBTL (Parallel Bridged) Class‑D amplifier based on the Texas Instruments TPA3255. The design is intended to house three amplifier modules in a single 2U rack enclosure and includes front‑panel controls such as button‑enabled DC‑coupling, balanced XLR inputs/outputs, and protection/status indicators.
