Nx Audio Rx 4000 Circuit Diagram Jun 2026

~28-30 Kgs (due to the robust transformer and heatsinks). Cooling: 4 individual cooling fans. 5. Where to Find the Schematic

Before analyzing the individual schematic blocks, it is vital to understand the primary power delivery metrics found on the official NX Audio Product Page. These metrics dictate the load requirements and operating voltages managed by the circuit board: Operational Metric Specification Details High-efficiency Class AB Configuration Power Output (2 Ohms) 1550W + 1550W RMS per channel Power Output (4 Ohms) 1150W + 1150W RMS per channel Power Output (8 Ohms) 700W + 700W RMS per channel Bridge Mode Power 3400W RMS @ 4 Ohms / 2400W RMS @ 8 Ohms Damping Factor >400 into 8 Ohm loads Frequency Response 20Hz to 20kHz Built-in Crossover Switchable 160Hz Low-Pass / High-Pass / Bypass 🔍 Technical Analysis of the RX 4000 Circuit Diagram

⭐⭐⭐⭐☆ (4/5)

The RX 4000 schematic can be broken down into several distinct stages. Locating these on the is essential for troubleshooting. A. The Input & Pre-Amplifier Stage

The NX Audio RX 4000 is a stalwart in the professional audio reinforcement industry, known for its rugged reliability and substantial power output, particularly in live sound and DJ applications. Understanding its is key to repair, maintenance, and unlocking the full potential of this heavy-duty Class AB amplifier . nx audio rx 4000 circuit diagram

This is the critical intermediary stage on the circuit diagram.

A complex part of the rx 4000 diagram is the protection logic. You will find:

If you can share a photo of the actual RX 4000 board or note whether it’s or PA mains powered , I can give more precise component IDs and test points.

The diagram is a multi-page PDF (usually 4–5 sheets) covering the power supply, input stage, main amplifier section (both channels), and protection circuit. Component labels (R12, C23, Q7, etc.) match the actual silkscreen on the board—this was a relief. ~28-30 Kgs (due to the robust transformer and heatsinks)

Understanding the circuit diagram of the NX Audio RX 4000 is essential for audio engineers, bench technicians, and electronics enthusiasts who need to maintain, troubleshoot, or repair these workhorse units. This article breaks down the internal architecture, power supply design, amplification stages, and protection mechanisms found within the RX 4000 schematic. Structural Overview of the Amplifier Architecture

Thermistors mounted on the heatsinks monitor operating temperatures. If the temperature exceeds safe limits (usually around 90°C), the circuit mutes the audio or cuts power until it cools down.

If you are considering this amplifier for your system, its official specifications provide a reliable reference for its power and performance. If you need the schematic for troubleshooting or repair, your best course of action is to contact the manufacturer or search in specialized tech forums.
