Use an M6 screw to attach a grounding wire to the front or rear grounding point on the enclosure.2. Route the wire under the frame of the enclosure and connect the wire to your facility’s earth ground connection. (figure 1)figure 1Grounding wireLock or unlock the front or rear doorFor additional security, the front and rear door of the enclosure can be locked with the provided door keys.• To lock or unlock the front or rear door of the enclosure, insert one of the provided door keys in the lock on the door and turn the key clockwise or counterclockwise.Remove the side panels1. If the side panels are locked, use the provided side panel keys to unlock the panels.2. Pull the two tabs on the side panel towards the center of the panel. (figure 2)figure 2figure 33. Lift the side panel free from the enclosure. (figure 3)4.Repeat steps 1 to 3 to remove the other side panel.To put the side panels back on the enclosure, place one of the side panels in the groove at the bottom of the enclosure. Pull the two tabs on the side panel towards the center of the panel, push the top part of the side panel into the enclosure, and release the tabs. Use one of the provided side panel keys to lock the side panel.figure 4Access your cablesThere are two cable access covers on the enclosure that you can remove to access and manage your cables.1. To take off a cable access cover, use a Phillips type screwdriver to remove the two screws on both ends of the cable access cover.2. Pull the cable access cover away from the enclosure. (figure 4)To put the cable access cover back on, place the cover over the cable access opening and use a Phillips type screwdriver to insert the screws through the cover and into the enclosure. Tighten the screws.Reverse the front doorTo accommodate different rack configurations, you can reverse the front door of the enclosure so that it opens to the left or right of the enclosure. The front door of the enclosure is attached to the enclosure with levers that are located at the top and bottom of the front door.1. In the top corner of the inside of the front door, pull the lever down and move the top corner of the front door away from the enclosure.2. In the bottom corner of the inside of the front door, pull the lever up and remove the front door from the enclosure. (figure 5)figure 53. Flip the front door so that the levers are located on the opposite side.4. Position the front door so that the top and bottom levers are aligned with the washers located in the hinge area of the enclosure.5. In the top corner of the front door, pull the lever down and release it into the washer and hole in the enclosure.6. In the bottom corner of the front door, pull the lever up and release it into the washer and hole in the enclosure. (figure 6)figure 6Adjust the depth of the mounting rails The mounting rails come pre installed in the enclosure. The mounting rails can be adjusted independently in 3/4 inch (20 mm) increments to accommodate different sizes of equipment.Warning! Do not attempt to adjust the mounting rails when equipment is installed in the enclosure. Remove the equipment first before you adjust the mounting rails.1. Each of the mounting rails is connected to the enclosure with a screw and cage nut in the upper and lower corners of the mounting rail. Use a Phillips type screwdriver to remove the screws and cage nuts from the mounting rails.2. Install the cage nuts at the desired depth.3. Slide the mounting rail to the depth of the cage nuts and use a Phillips type screwdriver to install and tighten the screws that you removed in step 1. (figure 7)figure 7Use the mounting rail tapped holesThe mounting rails come preinstalled in the enclosure but you can adjust the mounting rails so that you can use the tapped holes to install your equipment.Warning! Do not attempt to adjust the mounting rails when equipment is installed in the enclosure. Remove the equipment first before you adjust the mounting rails.1. Each of the mounting rails is connected to the enclosure with a screw and cage nut in the upper and lower corners of the mounting rail. Use a Phillips type screwdriver to remove the screws and cage nuts from the mounting rails.2. Change the location of the mounting rails so that the sides of the rails with the tapped holes are facing the front door. (figure 8)3. To reattach the mounting rails to the enclosure, use a Phillips type screwdriver to install and tighten the screws that you removed in step 1.figure 8Mount the enclosure to the wallWarning! Remove all equipment from the enclosure before you attempt to mount the enclosure to the wall.Warning! Wall structures vary and it is important to make sure that the type ofwall structure and mounting hardware that you are using will properly support the mounted equipment. Failure to do so might result in personal injury and/or equipment damage. The wall structure should be capable of supporting at least four times the weight of the mounted equipment.The RK12WALHM weighs 59.5 lb. (27 kg) and can hold up to 198 lb. (90 kg) in weight.Warning! If you lack the necessary expertise to attach this product to the wall that you’re using, contact a construction professional to install the enclosure or to provide specific mounting instructions for your wall structure.The number of mounting holes on the rear door of the enclosure will vary depending on the model of your enclosure. Each mounting hole can accommodate an M8, M10, 5/16”, or 3/8” bolt.• Follow the appropriate steps for the type of wall that you’re attaching the enclosure to and attach the enclosure to the wall.Caution! The enclosure is extremely heavy and you should not attempt to lift and hang the enclosure without the assistance of other people.Install equipmentWarning! Do not add equipment to the enclosure until the enclosure is securely attached to the wall.Warning! When you load equipment into this enclosure, load the heaviest equipment in the bottom section of this enclosure first. Continue loading equipment in a descending order of weight, so that the lighter equipment is installed in the upper sections of this enclosure and the heavier items are on the bottom.This enclosure comes with cage nuts and screws but the equipment you’re installing may come with mounting hardware. Consult the documentation that came with the equipment to determine the best mounting hardware that you should use and how you should install it.1. Decide where in the enclosure you want to install the equipment and insert the cage nuts in the mounting rails.2. Line up the mounting holes on the equipment with the cage nuts.3. Insert the screws through the mounting holes on the equipment and into the cage nuts.Technical support’s lifetime technical support is an integral part of our commitment to provide industry-leading solutions.

MU12 全频扬声器产品说明书
MU12音箱这个系统的设计采用的是免保护设计。大家 都知道有保护的扬声器音箱在使用过程中，特别是在保护电 路刚启动的时候，会有很多的电磁干扰对声音音质产生影响， 有些厂家的保护电路通过我们的检测发现，不仅没有保护作 用，还是一个干扰源。对于使用我公司跟随式保护电路可以 解决此类问题，但同样的会增加成本，因此MU12音箱在设 计当初我们就采用免保护设计的理念，尽量从减少干扰，提 高音质上考虑。
MU12音箱我们采用很多的新型材料，对于人们对于高 音比较敏感的听觉上考虑我们在高音驱动器上，经过多次试 验和测试实验，将高音驱动器的振膜改为了铝镁合金材料， 由于是合金材料，原理上讲，就具有比单一材料的阻尼要好， 3次谐波失真要小的特点，提高了高音单元的音质。
MU12音箱主要用于会议室、多功能厅、小型礼堂、宗教 会所、移动演出等场所。特别是对于人声的表现更是：“清晰， 饱满 ，且不失厚重”，这就是MU12音质特点。

扬声器的测量标准：
1.频率响应 噪声信号施加于扬声器，调整其电平，使扬声
器达到相当于标称阻抗下1W功率的电平，在消声 室环境中。距离扬声器1米处测试。
2.灵敏度 使用经过均衡曲线修正过的全频带粉红噪声信
号，施加于扬声器，将信号扩大，使扬声器达到相 当于标称阻抗下1W功率的电平，在消声室环境中、 距离扬声器1米处测得的平均声压级（dB-SPL）。
1. 请先阅读本说明。 2. 保留这些说明以供日后参照。 3. 注意所有警告信息。 4. 遵守各项操作指示。 5. 不要在雨水中或潮湿环境中使用本产品。 6. 不要将产品靠近热源安装，例如暖气管、加热器、 火炉或其它能产生热量的装置（包括功放机 ）。 7. 不要破坏极性或接地插头的安全性设置。如果提供 的插头不能插入插座，则应当请专业人员更换插座。 8. 保护好电源线和信号线，不要在上面踩踏或拧在一起（尤 其是插头插座及穿出机体以外的部分 ）。 9. 使用厂商规定及符合当地安全标准的附件。 10. 仅与厂商指定或与电器一同售出的推车 、架子 、三脚架、支架或桌子一起使用。推动小车/电器时，应谨防翻倒。 11. 雷电或长时间不使用时请断电以防止损坏产品。 12. 不要让物体或液体落入产品内——它们可能引起 火灾或触电。 13. 请注意产品外罩上的相关安全标志。
