Behringer NX3000 / NX-3000 PA 功率擴大機 — 舞台與 PA 系統專用，高功率驅動被動喇叭、耳朵牌、德國百靈達
商品介紹
Behringer NX3000 是一款專為 PA 系統、舞台音響與被動喇叭設計的功率擴大機。它可搭配中大型被動式喇叭，提供穩定且強大的輸出功率，使人聲、樂器或播放音源得以在較大空間中清晰、有力地傳播。無論是現場演出、Live house、教會、活動場館或酒吧，都適合使用 NX3000 作為音響核心驅動單元。相對於單純喇叭，配合 NX3000，你可以更靈活地選擇與配置音箱，並依場所需求調整輸出功率與音量。
由於它來自歐洲音響品牌 Behringer（俗稱「耳朵牌」／「德國百靈達」），在價格與功能上兼顧了「經濟實用」與「專業可靠」的平衡，是許多樂團、音響工程師、場館或業餘玩家常見選擇。
規格（典型 / 常見）
以下為 NX3000 的常見規格與功能 — 注意實際輸出功率與阻抗需依你所用喇叭與線路匹配：
-
功率輸出（Stereo 模式 / Bridge 模式）：足以驅動中大型 PA 被動喇叭／舞台喇叭系統。
-
適用範圍：PA 系統、舞台音響、場館音響、樂團／樂手使用。
-
模式切換：雙聲道 (Stereo) 或 橋接 (Bridge-Mono) — 以便在不同喇叭配置與功率需求間彈性使用。
-
適用設備：被動式喇叭 (Passive Speakers)、PA 喇叭、Active／Passive 混合系統 (視配置)
-
品質定位：中階至專業入門級功率擴大機 — 對於小型到中型場地與 PA 需求，具備不錯的性價比。
⚠️ 使用與匹配提醒：由於 NX3000 是功率放大機 (Amplifier)，它本身不是喇叭 (Speaker)。你需要搭配合適阻抗 (Impedance) 與承受功率 (Power Handling) 的被動喇叭，才能發揮它的驅動能力。若使用喇叭阻抗過低或功率不夠，就可能導致音箱失真、過熱或損壞。

NX3000
The NX3000 power amplifier packs 3000 Watts (2 x 1500 Watts @ 2 Ohms; 2 x 900 Watts @ 4 Ohms; 3000 Watts into 4 Ohms bridge mode) into exceptionally lightweight (7.7 lbs / 3.5 kg) and rack-mountable packages. And because the NX3000 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 its conventional counterparts. Thanks to our "Zero-Attack" limiters that offer maximum output level with exceptionally-reliable overload protection and SmartSense Loudspeaker impedance compensation, which provides fully linear frequency response at any speaker load impedance, you can run the NX3000 full-out for hours on-end. Our revolutionary high-density Class-D technology, combined with an ultra-efficient, switch-mode power supply ensure this feather-light powerhouse will drive your rig effortlessly for many years to come.
Class-D - Massive Power, Perfect Sound
Thanks to our High-Density Class-D amplifier Technology, we are able to provide you with enormous power and incredible sonic performance in an easy-to-use, ultra-portable and lightweight package. Class-D amplification makes all the difference, offering the ultimate in energy efficiency-and eliminating the need for heavy power supplies and massive heat sinks. This amazing technology makes it possible to design and build extremelypowerful products that are significantly lighter in weight than their traditional counterparts, while using less energy and protecting the environment.
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 Limit LEDs to indicate when the amplifier is running at full capacity. Just as elegant as the front, the rear panel is home to the combo XLR and 1/4" TRS Input connectors, making the NX3000 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 the NX3000 amp to run in your choice of dual mono, stereo or mono bridge modes. The NX3000's built-in Crossover switch sets the amp to Full-Range mode, where the output is sent unfiltered to your loudspeakers, or Bi-amp mode, which sends only the low-frequency content (<100 Hz) to passive subwoofers, while the high-frequency content (>100 Hz) is channeled to your full-range loudspeakers.
SmartSense Impedance Compensation
Our new SmartSense Technology puts the punch back into Class-D amplification, providing vastly improved full-range frequency response with more powerfully-dynamic bass, and smoother high-frequency reproduction. The resulting output is no longer dependent on the actual load, but is rendered perfectly ruler flat via impedance compensation. NX3000's design also incorporates a significantly-higher damping factor that yields better amplifier control over the loudspeaker for stronger audio reproduction especially in the LF area.
Sound Value
Sporting massive output ratings, lightweight Class-D technology and an equally lightweight price tag plus all the amenities a professional audio engineer could ask for the BEHRINGER NX3000 power amplifier is a serious amp for your most demanding applications.
