The NX Audio RX 4000 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. Circuit Breakdown & "Deep Story"
The "deep story" of the RX 4000's circuit lies in its focus on thermal management and component density:
High-Power Output Transistors: The unit typically utilizes a massive bank of transistors—for instance, similar models in the series like the MT1601 use up to 28 pairs of NJW0302 and NJW0281 transistors to handle extreme current without failure.
Power Supply Headroom: To ensure it doesn't "sag" during heavy bass notes, the power supply often incorporates a massive toroidal transformer and high-capacitance banks (e.g., 15000uF/100V capacitors) to provide instantaneous energy.
Protection Suite: The circuit is "deep" with safety features, including CLP™ (Clip Limiter Circuit) to prevent distortion from damaging speakers and DC inrush protection via Carling switch circuit breakers.
Built-in Crossover: Unlike standard power amps, the RX series often features a built-in crossover, allowing it to be switched between subwoofer (low-pass) and mid-high (high-pass) modes without external gear. Technical Resources
