The devices are available with different supply voltage ranges and work according to the open-circuit principle. Operating modeThe CM-SRS.1 with 1 c/o (SPDT) contact are available in 2 versions with 3 measuring ranges: 3-30 mA, 10-100 mA, 0.1-1 A (CM-SRS.11) and 0.3-1.5 A, 1-5 A, 3-15 A (CM-SRS.12). The measuring range is selected by connecting the monitored wire to the corresponding terminal B1/B2/B3-C.The units are adjusted with front-face operating controls. The selection of over- b or undercurrent monitoring a ismade with a DIP switch. Potentiometers, with direct reading scale, allow the adjustment of the threshold value I and of the hysteresis %. The hysteresis % is adjustable within a range of 3 to 30 % of the threshold value.Function diagramsOvercurrent monitoring bThe current to be monitored (measured value) is applied to terminals B1/B2/B3-C. The control supply voltage applied to terminals A1-A2 is displayed by the glowing green LED.If the measured value exceeds the adjusted threshold value, the output relay energizes and the red LED (overcurrent) andthe yellow LED (relay energized) glow.If the measured value drops below the threshold value minus the adjusted hysteresis, the output relay de-energizes and the red and yellow LEDs turn off.Undercurrent monitoring aThe current to be monitored (measured value) is applied to terminals B1/B2/B3-C. The control supply voltage applied to terminals A1-A2 is displayed by the glowing green LED.If the measured value drops below the adjusted threshold value, the output relay energizes, the red LED flashes W (undercurrent) and the yellow LED (relay energized) glows.If the measured value exceeds the threshold value plus the adjusted hysteresis, the output relay de-energizes and the red and yellow LEDs turn off.Data sheet | Current monitoring relays CM-SRS.1 -

SRS WOWSRS WOW能显著提升压缩音频的动感音质表现力、扩展音域并强化重低音震撼力。

这些改善让听众获得了无与伦比的高质量优美音色享受。

SRS WOW使用一种全景三维音象，从水平和垂直方向扩展了音场，同时使听众能感受到的低音频率远远低于驱动系统所能支持的低频段。

WOW是SRS实验室原先的四种处理技术完美的集合体。

首先，由一组人头传递函数将立体声场进行扩展与提升，从而使得它与实际扬声器位置相比远远得宽广和生动得多。

然后，通过一种专利心理声学技术，有选择性地将一些在所用扬声器实际承受范围能力之内的低频成分谐波进行增益提升，强化低音表现力。

对于单声道音源，有一种专利技术能合成一个非常自然的立体声场，并没有传统的立体声合成技术不自然的缺陷。

最后，由第二组人头传递函数对声音中的空间信息进行均衡，把声场从扬声器或耳机的水平边界外进一步扩展。

这些人头传递函数的校正曲线能使人脑将音源的位置分析成在其他的特定位置，即便实际扬声器放置在人的前方。

这样一来，整个房间内对音源中各种乐器、歌手的空间定位性都非常好，并且有明显的环绕立体声感受。

对于耳机系统，所使用的人头传递函数将音场从耳机内部扩展到了整个头部的外围。

这一强大的音频处理技术包括了大量的控制与设置，可以使其适用于各种具体产品及回放环境。

不仅如此，WOW中的各个组成部分可随意组合，以适应不同场合的特殊需要。

SRS 3D能恢复声音中的空间信息、导向信息以及其他的细微差别。

这些差别极可能在播放或录制的过程中被错位或丢失。

SRS Focus能纵向提升立体声场并改善语音清晰度。

它可以在很多扬声器位置较低的不理想场合（如汽车或背投电视）中将整个声场提升到一个合适的听觉高度。

而TruBass的心理声学提升技术营造了比扬声器最低截止频率还要低频的深沉、润泽的低音感受。

它能应用于任何扬声器或耳机上，而对于非常小型的扬声器系统特别有效，因为它使得无需再要额外的低音扬声器或附件了。
