Power:  
Introduction: Thank you for your purchase of a Knoll active  
balun system. This system is specifically designed to send a  
stereo line level and an infrared signal safely down a cat 5 or cat  
5e wire up to 1000 feet without encountering noise problems.  
Balun is an acronym for:  
Send Unit: 12 VDC unregulated (one PS1202 will power one  
each send and receive).  
Receive Unit: 12 VDC unregulated (one PS1202 will power one  
each send and receive).  
Infrared:  
BALance – UNbalance  
Send Unit: One stereo 3.5mm jack to connect one single or one dual  
emitter.  
The send module takes a conventional stereo line level signal  
and balances it (signal is not tied to a ground reference) then  
sends it via cat 5 to the receive module (with power from the  
send module). The receive module unbalances the stereo 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.  
Receive Unit: One triple 3.5 mm jack to connect a three wire Knoll or  
other infrared receiver. Supplies 12 VDC power for infrared receiver  
without requiring another power supply.
