美国JBL:PRX618S-XLF单18吋有源超重低频音箱

JBL PRX618S-XLF 单18吋有源超重低频音箱



更强大



忘掉功率、大声压级这些评价有源扬声器水平的指标，在这些重要的指标上，PRX600全系列表现都非常出色。JBL一直致力于优化扬声器和功放的表现，了扬声器大功率输出、准确的动态以及清透的音质。我们推荐您使用PRX600跟同档次的扬声器作试听比较，您会发现，它们声音清澈高扬、优美动听。





更稳定



JBL有着60年的生产历史，有着无可比拟的经验，在设计中不断优化扬声器的性与可靠性。实际上，JBL在40年前生产的扬声器到现在还没退出舞台。无论是户外演出还是演艺场馆，客户每天的演出或演讲靠的就是扬声器，扬声器就是他们的一切----一旦扬声器出现故障，他们就无法工作。这责任重大！因此，JBL新推出了稳定、、抗损的PRX600系列，经长时间测试，PRX600系列经得起流动演出和恶劣固定安装环境的严酷考验。



更多功能



PRX600全新系列扬声器外形、，无论对音乐人、艺人、安装工程商、A/V租赁公司或者是任何需要的扬声器的场所，这都是一个非常吸引人的选择。在设计上，PRX600内置了多个悬挂吊点方便安装和调校角度，并配套了双角度支架孔方便地面安放，更吸取了JBL Tour系列产品的优点，并在此基础上做出一系列非常好的改进，使得扬声器更小、更轻，是真正意义上的便于携带以及方便安装和操作。

Applications :

The PRX618S-XLF, extended low frequency subwoofer was designed and engineered to provide sub bass frequencies with accuracy and power. Used as a single sub in a sub/sat system or in multiples as part of a scalable, large format sound reinforcement system, the PRX618S-XLF performs with extreme efficiency and control. The subs are stackable and light-weight ensuring quick set-ups and tear-downs. And due to their rugged construction are perfect for AV rental inventories. With a pole receptacle (that accepts a SS4-BK or SS4-BK24) on the top panel and integrated stereo pass-thru this is the most powerful low-frequency complement to the PRX full-range systems. The addition of a polarity reverse option further enables system optimization.



The PRX618S-XLF is a high performance self-powered subwoofer system. The PRX618S-XLF is comprised of a powerful 2268FF Differential Drive? dual voice-coil and magnetic gap, neodymium woofer driven by a 1000 Watt (dual 500 watt) Crown Class-D power amplifier. Dual-Bridge Technology? directly links discrete amplifier channel outputs to each voice coil in the Differential Drive woofer. Electrical power transfer to the transducer is optimized for more power performance. A proprietary DSP chip is at the core of a fully featured input section, providing user selectable cross-over functionality, polarity optimization, protection, dynamic limiting and discrete component optimization.



The amplifier input panel offers stereo inputs with XLR or ? inch jack compatibility. A user selectable crossover ensures a smooth transition to full-range system connected to the stereo outputs. Signal present and limiter lights indicate the system status and assist in setting the optimum level, via the level control knob.



All PRX600 cabinets are built from a combination of 25mm (on the top and bottom for added rigidity) and 18mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints. All PRX600 Series cabinets are protected by JBL’s tour proven DuraFlex? finish. Grilles are made from dent-resistant 16 gauge steel and handles are made from light-weight glass-filled nylon for added strength and durability.



Special note: JBL highly recommends that no more than 70 lbs of weight be placed on a speaker pole that is mounted to a PRX618S

or PRX618S-XLF.
