4. Output Stage (Power Amplification)

This is the high-power section on the diagram, easily identified by the rows of power transistors. The NX Audio RX 4000 is a professional-grade,

Technicians often refer to the circuit diagram to address common issues like "shorting" or thermal shutdown. nx audio rx 4000 circuit diagram

1. Topology: The RX-4000 typically utilizes a Complementary Symmetry Push-Pull configuration (Class AB).
2. Output Transistors: These are NPN and PNP power transistors (commonly 2SA1943 / 2SC5200 pairs or TIP series depending on the revision) mounted on the heatsink. They work like fast switches, sourcing current from the positive rail (positive half of wave) and sinking to the negative rail (negative half of wave).
3. Bias Servo: A transistor (often attached to the heatsink) monitors temperature and adjusts the bias voltage to prevent "crossover distortion" and thermal runaway.
