Behringer NU-3000 เพาเวอร์แอมป์ Ultra-Lightweight, High-Density 3000-Watt Power Amplifier

The iNUKE NU3000, like the rest of the iNUKE Series power amplifiers, packs massive amounts of output power into an exceptionally lightweight, rackmountable package. Behringer's revolutionary high-density Class-D technology combined with ultra-efficient switch-mode power supplies ensures this feather-light powerhouse will drive your rig effortlessly for many years to come.

Superb transient response

Behringer spent years fine-tuning the high-density Class-D technology that gives the iNUKE Series its oomph. By carefully selecting transistors with extremely high slew rates and optimizing other proprietary parts of the circuitry, this amp reacts instantly to even the most demanding electronic bass impulses.

When this amazing amplifier technology is combined with Behringer's state-of-the-art switching-mode power supplies, this amplifiers= provides tremendous punch. And, because it is so much more efficient than conventional designs, it runs cooler and doesn’t require the massive heat sinks and heavy toroid transformers typically associated with other conventional counterparts.

Sublimely simple operation

The front panel controls and indicators provide your system’s vital signs at a glance. After pressing the Power button, the Power LED lights to show the amp is ready for action. All channels feature positive-detent Gain controls with Signal LEDs that light when a signal is present, as well as clip LEDs to indicate when the signal is distorted and you need to reduce the input signal.

The rear panel is just as elegant, with combo XLR and 1/4" TRS input connectors making the iNUKE NU3000 compatible with virtually any source, balanced or unbalanced. Professional twist-lock speaker sockets are provided to ensure every drop of output power gets to your loudspeakers.The rear panel is also where you’ll find the switches that enable iNUKE amps to work in either dual mono, stereo or mono bridge mode. A built-in CROSSOVER switch enables the amp to operate in bi-amp mode, sending low frequency content to passive subwoofers, while the high-frequency output is channeled to full-range loudspeakers (CH1>100 Hz / CH2<100 Hz or FULLRANGE). Flick the LIMITER ON/OFF switch to activate the built-in overload protection, or turn it off if you’re feeling lucky.
