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:

BAL

ance –

UN

balance

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.

Features:

•

Tabletop box design or Decora™ style available.

•

Safely sends stereo signals up to 1000’ (300 m).

•

Sends infrared signal from receiver back to sender.

•

PS1202 power supply required on send side only.

•

Mix and match tabletop and decora style.
