NX Audio RX 4000 is a professional power amplifier built on a Class AB circuit
: The amplifier runs on a lower voltage rail (e.g., ±60V DC) for low-volume signals.
The is more than just a wiring picture; it is a diagnostic engine. Whether you are repairing blown MOSFETs due to voltage spikes or recalibrating the idle current after a component upgrade, the schematic guides every solder joint and measurement. nx audio rx 4000 circuit diagram

The VAS uses transistor pairs configured as current mirrors to ensure linear amplification and low distortion. NX Audio RX 4000 is a professional power
V2). When the audio signal is low, the amplifier runs on the lower voltage rails to reduce power dissipation. When a high-amplitude transient occurs, steering diodes or MOSFET switches rapidly connect the output stage to the higher voltage rails.
