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.
