皇冠CROWN XLS-202D 音频功率放大器
XLS202包含着一系列优异特性与*的可靠性能。每个通道上的高通滤波器由三档选择，包括(30Hz/15Hz/关闭)。用于全频音箱时，可以选择30Hz或15Hz，用来防止无用的**低频信号过载低音单元。用于**低音时，可以关闭。
采用金属封装的输出器件，虽然它比其他厂家使用的塑封输出器件贵的多，但是它的效率和可靠性很高。
采用先进的设备检测了每个器件的功率曲线和峰值功率处理能力，然后刷选和配对。
采用坚固的全钢质机壳，并配置*强制式风扇以免过分热量聚积。

Legendary Crown quality at an easy price.
330W/ch @ 2 Ω, 300W/ch @ 4 Ω, 200W/ch @ 8 Ω, 660W bridged mono @ 4 Ω, 600W bridged mono @ 8 Ω. Designed to provide the quality, power, and reliability you expect from other Crown amps with many of the same controls and features for a much friendlier price.
Features sophisticated protection circuitry (from shorted, open, or mismatched loads, input and high frequency overloads), 5-way fault indicator, red LED on each channel that turns on when distortion becomes audible, green **-present LED that flashes when the level is extremely low (indicating cabling problems), and detented level controls. Mode select switch for stereo or bridged; 3-speed fan; and XLR inputs and Speakon or binding post outputs; all in a rugged steel chassis designed to handle serious road use.
