QSC:DCA1824 四声道功率放大器技术参数

QSC DCA1824 四声道功率放大器

声音技术的最新发展，如杜比数字环绕声-EX 和三分频放大，均要求功放提供比以前更多的声
道。为此，QSC 设计了全新的DCA功放，在不增大原系统功放轻巧体积的前提下提供4 个功率放大
声道。与两声道立体声功放相比，4 声道功放更经济实用。除具备卓越的性能外，QSC 还在4 声道功放
上增加了一些专为电影市场设计的特点。

DCA1824 最适合环绕声道－每声道可以驱动4 个并联的8 欧姆扬声器，最多可驱动16 个环绕声扬声器
DCA1644 最适合驱动中小影厅的银幕声道或驱动大型影院三分频扬声器系统的高音和中音
DCA 功放设有连接QSC DCM数字影院监控器的数据口，两者结合使用大大降低了人工和连线成本
采用功波技术，以适应当今数字声声迹所需要增加的动态范围
体积小（2U 高，14 英寸深），适合安装在落地机架上的声音系统
很适合将现有系统升级到杜比数字环绕声-EX，而不需要增加机柜空间
所有DCA 型号功放仅重21 磅，安装及运输十分方便
在开电源时，有效的浪涌限制作用不会烧断电路断路器
增益控制安全罩，防止误操作

电气规格：
输出功率8Ω 170×4
输出功率4Ω 250×4
输出功率2Ω 450×4

Description:
Drives 8 ohms per channel with 170 watts(FTC 20 Hz-20 kHz 0.05% THD), 4 ohms per channel with 250 watts (EIA 20 Hz-20 kHz 0.1% THD), 2 ohms per channel with 450 watts (2 ohms EIA 1 kHz 1% THD). Features include: Active Inrush Limiting won't blow circuit breakers at turn-on, both speaker and monitor panel outputs, a hum-free noise floor and ultra low distortion, optional crossover modules for bi-amp, tri-amp, & subwoofer applications, only 3.5 inches high (build the most powerful systems in a single rack), dataport interface for DCM (Digital Cinema Monitor), only 21 lbs for easier racking and shipping, 14" deep (fits standard racks for lower cost and less floor space), custom gain control security cover protects amp from misasdjustment, LED indicators for metering, status, and operating mode, front panel LED's indicate parallel and bridged mono modes. The DCA 1824 is ideal for surround channels-each channel can power up to four 8 ohms speakers in parallel for a total of up to 16 speakers. With PowerWave technology, DCA amplifiers take your soundtracks to a whole new level. Not only does it give your music bigger bass and cleaner highs, PowerWave also cuts wasted heat and boosts reliability. PowerWave is a switching power supply that provides ample current to the audio power circuitry by charging the supply rails 230,000 times a second through an ultra-low impedance circuit, so unlike high- powered amps with conventional supplies, the audio signal is never starved prematurely, but remains crisp and clean. It virtually eliminates hum and greatly reduces noise, providing a vast dynamic range that can handle the most demanding digital soundtracks without running out of headroom. DCA Series amps also boast a set of useful features such as individually selectable clip limiters and subsonic filters; and stereo, parallel, and bridged mono operation.
