The NX Audio RX 4000 is a high-power professional PA amplifier. Its circuit design follows the standard Class-AB topology common to robust audio amplifiers of this class, designed to handle low-impedance loads (4Ω–8Ω) and 100V/70V constant voltage systems. “NX Audio RX 4000 circuit diagram” Here’s a

• Locate the Speaker Relay (typically a white or black box near the speaker terminals).
• Trace the relay coil back to the protection IC. Check if the relay driver transistor (often a 2N2222 or similar) is receiving voltage.
• Check the Mute Circuit: In the preamp stage, look for a transistor that shunts the audio signal to ground during power-up. If this transistor is shorted, you get silence.

Review: NX Audio RX-4000 Circuit Diagram

While official schematics are typically restricted to authorized service centers, common components identified in the RX series include: Locate the Speaker Relay (typically a white or

For a visual "walkthrough" of the board and component layout, see the RX 4000 full circuit study or the Power Supply Repair Guide on YouTube .

Before you order replacement MOSFETs or op-amps, take the time to study the power supply section of the diagram. Locate the PWM controller, measure its Vcc pin for voltage, and verify the feedback loop. With the correct schematic in hand and a multimeter, even a complex failure in the RX 4000 becomes a manageable repair.
