Behringer NX3000 Amplifier

Behringer NX3000 Class D Power Amplifier — 3000 W in a 2U Rack

The Behringer NX3000 is a 2-channel Class D power amplifier built for live sound and mobile PA systems that need serious wattage without transformer weight. Output stages deliver 2x 900 W into 4 Ω, 2x 1500 W into 2 Ω, and 3000 W bridged into a single 4 Ω load, covering full-range tops and subs. This amplifier is the right choice for working musicians and small-to-mid venue operators who need touring-grade headroom from a 3.5 kg chassis.

SmartSense Impedance Compensation and Switch-Mode Efficiency

Two technologies separate this amp from typical Class D designs in its tier. SmartSense loudspeaker impedance compensation shapes the output so the frequency response stays linear regardless of cabinet impedance. The switch-mode power supply replaces the heavy toroid transformer, dropping chassis weight to 3.5 kg with tight transient response.

Power Output and Channel Configuration

Three operating modes give engineers flexibility. Stereo drives two independent cabinets, mono sums both inputs, and bridged unlocks the full 3000 W into a single subwoofer load.

• Power Output: 2x 900 W @ 4 Ω, 2x 1500 W @ 2 Ω, 3000 W bridged @ 4 Ω — covers full-range tops and sub stacks
• Number of Channels: 2 — switchable Stereo, Mono, or Bridged modes
• High-Density Class D topology runs cool without massive heat sinks

Limiters, Crossover, and Driver Protection Built In

Built-in processing protects drivers and adapts to common PA topologies without external gear. The 100 Hz crossover supports bi-amp setups with separate sub and top amps.

• Zero-Attack Limiters: per-channel — maximum output with reliable overload protection
• SmartSense Impedance Compensation: linear frequency response at any speaker load
• Switchable 100 Hz crossover with high-pass, low-pass, and full-range modes for bi-amp rigs

Inputs, Outputs, and Rackmount Construction

Twist-lock Speakon connectors prevent mid-show disconnects, and the variable-speed fan pulls air front-to-back through the chassis for cool operation under sustained load.

• Inputs: 2x combo XLR / 1/4" TRS — balanced and unbalanced sources accepted
• Outputs: 2x twist-lock Speakon — secure locking connection for passive cabinets
• Frequency Range: 20 Hz - 20 kHz — full-bandwidth reproduction for music playback
• Drops into any standard 19" rack at just 3.5 kg and 2 RU

Who Should Choose the Behringer NX3000

The NX3000 is the right choice for mobile DJs, small bands, and house-of-worship sound teams who need 3000 W of headroom without breaking the budget. Solo performers running a sub-and-top rig benefit from the integrated 100 Hz crossover and bridged-mode output, while venue operators get reliable thermal protection for long event days. The 3.5 kg chassis makes load-in easier than older transformer-based amps.

Behringer NX Series — Class D Amplification for Working Players

The NX series sits in Behringer's lightweight Class D amplifier lineup, bringing switch-mode efficiency and SmartSense compensation to musicians who previously chose between weight and wattage. This model sits in the middle of the family between the NX1000 and the NX6000, delivering 3000 W of bridged output in the same 2U form factor.
