Introduction: Thank you for your purchase of a Knoll active  
balun system. This system is specifically designed to send a  
three wire Pb, Pr, Y component or RGB and Digital Audio or  
S/PDIF (Dolby® digital or DTS®) signals safely down a single  
cat 5 or cat 5e wire up to 500 feet (250 feet for 1080p) without  
encountering signal degradation problems. Balun is an acronym  
for:  
Input and Outputs:  
Quad Receive Modules: four gold RCA input jacks, one RJ-45  
out-jack, one-DC power input.  
BALance – UNbalance  
US4-Hub: Four RCA input jacks, six RJ-45 output jacks, one DC  
power input, one input and one output link RJ45 jack.  
The hub is a send module and takes a conventional component  
signal and balances it (signal is not tied to a ground reference)  
then sends it via cat 5 to a receive module. The receive module  
unbalances the component signal back to its former state. This  
process does not allow any stray magnetism of any sort to  
contaminate the signal while it is being transported.  
Power  
Receive Unit: 12 VDC 40mA.  
US4-Hub: 15 VDC (one PS1506 included).  
This US4-Hub requires up to six Knoll US Quad receive modules  
(enclosure or decora in-wall style) to operate. Each quad receive  
unit also requires a PS1202 power supply.
