Knoll Systems UDR-STEREO RECEIVER, UDS-STEREO SENDER, US-STEREO SENDER, UR-STEREO RECEIVER PS1202

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.
