Nx Audio Rx 4000 Circuit Diagram -
: Low-noise op-amps handle the initial differential balancing and phase inversion for bridge-mono mode.
A professional amplifier must protect itself and the connected loudspeakers from catastrophic failures. The RX 4000 features several integrated protection sub-circuits:
For audio engineers, bench technicians, and DIY electronics enthusiasts, understanding the circuit diagram and internal schematics of this amplifier is essential for maintaining optimal performance, modifying the unit, or performing component-level repairs. 1.

Strengths
: Massive electrolytic capacitors (e.g., 10,000µF to 22,000µF per rail) smooth out voltage ripples. Protection Circuitry
Thermistors mounted to the aluminum heatsinks change resistance as temperatures rise. This circuit first ramps up the variable-speed cooling fans. If temperatures exceed safe thresholds (usually around 90°C), the circuit mutes the audio channel until it cools down.
: Managed by four individual cooling fans to maintain stability under stress.
