(VLTM crossover circuit) with a 24dB/octave slope for easy subwoofer integration. Cooling System : The chassis houses four individual cooling fans to manage the heat generated by the Class AB architecture. Power Specifications The circuit is designed to remain stable even down to 2-ohm loads Load Impedance Power Output (per channel) 8 Ohms Bridged 4 Ohms Bridged Documentation Resources
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.
In Class H circuits, faulty steering diodes or MOSFETs can prevent the amplifier from switching to the high-voltage rail, causing premature audio clipping. If you need help with a specific repair, tell me: nx audio rx 4000 circuit diagram
: Employs high-power Bipolar Junction Transistors (BJTs) and MOSFETs to drive heavy loads .
The is a professional-grade 2-channel power amplifier, often cited as a "workhorse" in the live sound industry for its high power output (up to 1550W + 1550W @ 2 Ohms ) and robust reliability. Its circuit architecture typically employs a Class H design , which uses a multi-tier power supply to maximize efficiency and reduce heat buildup—crucial for demanding environments like nightclubs and stadiums.

Nx Audio RX 4000 Circuit Diagram: A Complete Technical Guide
The circuit diagram typically indicates three primary wiring configurations: Stereo Mode: Independent operation of both channels. Parallel Mode: Sends a single input signal to both output channels. Bridge Mode: Locate the PWM controller, measure its Vcc pin
: The amplifier runs on a lower voltage rail (e.g., ±60V DC) for low-volume signals.
