I picked up a used NX Audio RX 4000 that had a blown channel and no schematic included. After searching for the “NX Audio RX 4000 circuit diagram,” I found a few sources—some paid, some forum-shared. Here’s what actually worked.

: A specialized system protection circuit is a core feature, providing: Short Circuit & Overload Protection : Prevents damage during output faults. DC & Thermal Protection : Guards against DC offset at the speakers and overheating. Soft Start : Reduces inrush current during power-up. Signal Processing : Includes built-in 120Hz Hi-Pass and Low-Pass filters

: Shuts down output if a short is detected in the speaker lines .
