1.EMC171724S is a high-quality cascading satellite TV engineering system with more than 24 users. There are many large-scale cases with more than 25 floors.The technicians should use good quality satellite antennas and LNBs to ensure the stable signal sourse when installing.
2.This multiswitch has been designed with an internal preamplifier at the LNB signal input, so a single set of projects generally does not need to add a preamplifier; if it is a group of antenna systems work for several groups of user systems, it needs to selected slope amplifier appropriately according to slope loss.About the slope amplifier please directly consult the business contact.
3.The cable between LNB and multiswitch should be kept within 30 meters.The simplest standard is to test with DVB. The cable port signal of the multiswitch input should be stable.The 4 outputs LNB of this product can be Quad LNB and Quattro LNB.
4.The cable length between DVB and multiswitch should be kept within 60 meters,and good quality coaxial cable can support longer.
5.When installing, connect the user port at the front end of the multiswitch (close to LNB signal input port) to the farthest user. The user port at the end of the multiswitch is connected to the nearest user. Because the signal at the front end is always slightly stronger than that of the end during normal working.
6.When cascading more multiswitches, if the cascading cable length between the front multiswitch and the rear multiswitch is less than 12 meters,then no need to add an amplifier. The rear multiswitch can obtain a completely lossless TV signal. Theoretically, an infinite number of 171724S mulswitches can be cascaded. However, due to the uneven loss caused by connectors, cables, etc.,the max cascading multiswitches number is 12. If more users are needed, it is recommended to use two or more sets of parallel systems. Better to use slope splitter in parallel,which will offer a more balanced and stable signal.
7. Customers who require a high quality slope splitter can directly consult the business contact.
8.The multiswitch is a high quality product developed by our company with signal stable and easy installation. It has a preamplifier, so its operating current is around 400mA. The power adapters supplied with our S series products are also exclusive products designed by our company (model EMC1830F), which is by no means a common power adapter on the market. When using the power adapter, the first multiswitch from the antenna system must be equipped with power adapter, because it needs to supply current to the LNB;Later no need to equip every multiswitch with a power adapter,can equip every two or three multiswitches with a power supply, because each multiswitch current consumption is only 400mA, the current of the power adapter is more than 2000mA, but in order to ensure the service life of the power supply,total current consumption can not be too much.
9.At present, some multiswitches have low operating current, no preamplifier and no gain adjustment function and no slope adjustment function. Only install a row of potentiometers on the surface to pretend to be our S series product. Please be careful and consult to know product clearly before give order.
