Sensors on the heatsink monitor temperature and shut down the amplifier if it overheats.
The complete schematic of the RX 4000 can be broken down into five primary functional blocks: Input Stage & Signal Processing
Due to the massive toroidal transformer and filter capacitors, turning on the amplifier creates a massive initial current surge. A soft-start relay forces the AC mains current through current-limiting thermistors or resistors for the first few milliseconds, protecting the venue’s circuit breakers. 7.
