SewellU-Link Ul10 , USB 2.0 Over Single CAT5E/6 Extender, 200 ft, 480 Mbps, 4 Port - V2.0

OK this USB 2.0 extender is a game changer. I've been searching for one that works with a 1080P webcam and this one delivered and I am running now 2 webcams at the same time a 1080p and a 480p over 100 foot ethernet cable. It also gave me about 35 MB transfer speed on my external hard drive which is very good works with keyboard and mouse also. I bought a cheaper one but it was too slow and wouldn't work with a 1080P webcam. Also you can plug the power adapter in at the computer side which frees up the hub end my other adapter you had to power it at the hub end which makes it more cumbersome.

Great, great unit, rugged and reliableAll the other great and helpful reviews on here were exactly right.Worth every pennyBUY IT!

Works to send output from one Amp to input on another Amp in another room

can not be used

OK, this is a real, isolated balun! I took it apart just to be sure (see photo), and there they are: the isolation transformers. You can also see from the photo that the traces are surrounded by a good ground plane with many vias to help shield the signal. Do not confuse this product with the $10 units that only wire the RCA connectors directly to the CAT twisted pairs. Those cheaper units will not protect your signal!Basically, these isolation transformers "float' your audio signal so that it is no longer referenced to any other potentials. What this means is that your audio signal is not disturbed by stray magnetic fields or differences in the ground potential between your sender and receiver equipment, both of which can be significant over longer distances. It's worth the extra money to avoid that 60Hz hum or other noise in your audio signal. Also, these baluns are passive so you don't need to hook up any connection to a power source.
