QSC RMX5050 专业功率放大器

技术参数：

QSC RMX5050功率放大器具有领先的专业性能和质量以及合理的价位,适用于各种扩声场和包括专业流动演出、音乐家演奏、对于要求持续大功率输出、非同反响的声音表现和要求高可靠性的用户来说，RMX大功率放大器是明智的选择。

 与它的“小兄弟”（RMX1850DH）一样，RMX5050采用了三层H级放大电路设计，RMX5050在实际使用中的效率非常高。交流电流损失小，更多的电流可用于产生有用的音频功率。RMX5050采用了优良组件使峰值功率比RMX4050HD提高了25％。

 像所有RMX功率放大器一样，RMX5050配有平衡1/4英寸的TRS，XLR和条形端子输入，接线柱和Neutrik Speakon TM 扬声器输出、前面板增益控制和监视功放状态用的信号和削波LED指示灯。

主要特点：

·RMX5050是RMX系列中的旗舰产品，拥有超大功率，物超所值

·RMX5050提高了散热效率，在2欧姆立体声和4欧姆桥接时提供更高的连续功率

·双路单声道，大电流供电提高可靠性和性能

·3RU高，进深40.6厘米

·专业品质－融合了经过实践证明的QSC成功设计

·大电流环形变压器使2欧姆负载输出更大、噪声更低

·独立用户可选用的削波限制器减少失真

·可选低频滤波器（30赫兹或50赫兹）保护扬声器，增益功率余量

功率放大器：机体尺寸紧凑,在2U空间中输出功率可达到2500W。专业质量性能-体现了已被证实的QSC的成功设计。大电流环形变压器使2欧姆负载输出功率更高,噪音更低。用户可选的削波限制器可将低失真。接线柱及Neutrik Speakon输出端子。可选低频滤波器(30Hz或50Hz)能保护扬声器,并提高峰值功率余量。1/4"(6.3mm)TRS平衡插孔,XLR插头和条型端子输入，信号和削波发光二极管指示灯可监视功放的工作状态，每声道独立的直流电源保护和热过载保护能自动地保护功放和扬声器

削波限制器

当RMX功放驱动困难时,削波限制器自动地找到过载点的确切位置,并使功放在其"峰值区域"保持工作并在不影响效果的情况下防止音质严重失真。低频滤波器和削波限制器均可在各声道独立调节。

输入滤波器

通过使功放和扬声器频带范围的匹配提高系统的响应能力.防止扬声器低频段音质混浊不清。每个声道单独可调: 采用最小型的全频带扬声器是为50Hz;采用次低音扬声器和大型全频带系统是为30Hz；采用录音棚监听时关闭。

QSC's RMX 5050 power amplifier represents the state-of-the-art in professional quality performance at an affordable price. Perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians, and mobile entertainers, the RMX 5050 is optimized to deliver high levels of sustained power, extraordinary audio performance and road-proven reliability.

Like its smaller sibling (the RMX 4050HD), the RMX 5050 features a three-tier, Class H design. The RMX 5050 is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. The RMX 5050 uses the best available component upgrades to increase peak power by 25% over the RMX 4050HD.

Like all RMX amps, the RMX 5050 features balanced 1/4 in. TRS, XLR and barrier strip inputs, binding posts and Neutrik Speakon outputs, front-mounted gain controls, plus signal and clip LED indicators to monitor performance.
