美国皇冠CROWN:XLS-202D 音频功率放大器技术参数

皇冠CROWN XLS-202D 音频功率放大器

XLS202包含着一系列优异特性与一流的可靠性能。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，用来防止无用的超低频信号过载低音单元。用于超低音时，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，并配置高效强制式风扇以免过分热量聚积。

频率响应（从20Hz-20KHz）XLS 202: ±0.75dB
相位响应（在1W时）XLS 202: 在10Hz时，-10°在20KHz时，+19°
信噪比（20Hz-20KHz）XLS 202: >100dB（A加权，在满负荷工作时）
总谐波失真（THD）XLS 202:: <0.15%（在满负荷输出时，从20Hz-1KHz）
互调失真（IMD）（4: 1时，在60Hz和7KHz）额定功率下，输出值为-40dB时XLS 202: <0.3%

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 signal-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.
