Overview

The Behringer NX3000 is a Class-D power amplifier designed to solve one of the most common problems in live sound: getting serious wattage into a package that won't break your back. Weighing just 7.7 pounds, it delivers up to 3000 watts in bridge mode or 2 x 1500 watts into 2-ohm loads — output figures that would have required a 40-pound amplifier just a generation ago. The Class-D topology and switch-mode power supply make this possible while also drawing less current from the mains, an important consideration when working with limited power at outdoor events or smaller venues.

Behringer's SmartSense Loudspeaker Impedance Compensation technology sets the NX3000 apart from basic Class-D competitors by actively correcting for the impedance variations inherent in real-world loudspeakers, resulting in a more linear and consistent frequency response. Input flexibility comes via both XLR and 1/4-inch TRS connections, while twist-lock speaker outputs provide the secure, locking connections that professional use demands. Thermal overload protection ensures the amplifier can operate reliably during extended sets, and the standard single-rack-space form factor integrates cleanly into any touring or installed rack setup. For sound professionals seeking raw power and portability on a budget, the NX3000 is a compelling workhorse amplifier.

Pros & Cons

👍 Pros

  • 3000 watts of total power in bridge mode provides substantial headroom for large venues and speaker systems
  • Ultra-lightweight at 7.7 lbs, making it exceptionally easy to transport and rack-mount
  • SmartSense impedance compensation maintains consistent frequency response across different speaker loads
  • 100 dB signal-to-noise ratio ensures clean, low-noise amplification
  • Twist-lock speaker connectors prevent accidental disconnection during performances

👎 Cons

  • No built-in DSP, crossover, or limiter — requires external processing for speaker management
  • Fan cooling can produce audible noise in quiet environments or recording settings
  • Basic front-panel controls with no LCD or detailed metering
  • Limited to two channels with no daisy-chain or network control capability
  • Build quality and components reflect the budget-oriented price point

Frequently Asked Questions

The NX3000 delivers 2 x 1500 watts into 2 ohms, 2 x 900 watts into 4 ohms, or 3000 watts into 4 ohms when used in bridge mode.
SmartSense is Behringer's technology that automatically adjusts the amplifier's output to maintain a linear frequency response regardless of the connected speaker's impedance characteristics, helping ensure consistent sound quality.
At just 7.7 lbs (3.5 kg), the NX3000 is dramatically lighter than conventional Class-AB amplifiers of similar power, thanks to its Class-D switching design and lightweight switch-mode power supply.
The NX3000 accepts input via XLR and 1/4-inch TRS connectors, and uses twist-lock (Speakon-compatible) connectors for speaker outputs, providing secure, reliable connections.
Yes, it includes thermal overload protection that prevents damage from excessive heat, along with additional safeguards to ensure stable and reliable operation during demanding use.
