Wiring: A send
module (UDS-Stereo
or US-Stereo) needs
to be connected to a
Knoll receive module
(UDR-Stereo or UR-
Stereo) to work
correctly. The send
and receive module
are connected using a single cat 5 wire using all 8 conductors.
Connection is made with the RJ45 connector (RJ45 plug not supplied).
Always use standard cat 5 wiring practices. Using the correct wire pairs
and polarity is VERY important.
Connection to stereo source equipment: Connect the two UDS-
Stereo or US-Stereo to gold RCA jacks with a good quality gold
connector RCA jumper cable to the appropriate stereo output jacks on
your receiver, tuner, CD player, switcher or other equipment.
If there is a switched power outlet on your output equipment, you may
want to plug the PS1202 power supply to the switched outlet.
Make sure a good quality RJ45 8-8 crimper is used to
connect the RJ45 connector to the cat 5 wire. Poor crimping
and mismatched wires are the most frequent cause of
installation problems.
Power requirements: The Knoll balun system requires a single
PS1202 power supply connected to the send unit only. In certain cases
with very long leads a higher voltage PS1506 15 VDC power supply
may be required if some noise or distortion is evident.
Connection to the amplifier, TV or other components: Connect
the two gold RCA jacks on the UDR-Stereo or UR-Stereo with a good
quality gold connector RCA jumper cable to the appropriate stereo
input jacks on your amplifier, receiver, TV or other component. Make
sure the correct stereo input is selected.
Multiple Connection(s): If the stereo signal needs to be sent to more
than one receiver, this can easily be accomplished by paralleling or Y
cording the inputs to the stereo send unit. Depending on the source
components output, it should be acceptable to Y cord up to ten send
baluns. Each Knoll stereo send balun is connected to one stereo receive
balun. Each stereo send unit requires a PS1202 power supply.
There is no balun hub available for the stereo balun system.
Infrared: The Knoll stereo balun system can carry infrared signals
from the receive unit to the send unit. To do this a three wire infrared
receiver (not supplied) is connected to the triple connection 3.5mm
stereo jack on the receive unit. The receive unit supplies 12 VDC power
for the receiver, so a separate infrared power supply is not required.
An IR54 or IR55 connection module is connected using the ground and
IR output terminals on the IR54 or IR55 and a mono 3.5mm jack
connected to the send module. The tip is the IR output. Infrared
emitters are then connected to the IR54 or IR55. If an emitter is
directly connected to the send unit without a connection block,
a 470 ohm dropping resistor needs to be inserted in series in the
emitter wire or the emitter will fail after a short period of time. Any
infrared commands sent from the receiver on the Knoll stereo receive
balun end is sent to the infrared emitter on the Knoll stereo balun send
side and rebroadcast there.
The Knoll send receive system does not have any
user adjustments and is completely automatic. If
need be, please call our tech line for details at 1
