Knoll US4 Leaflet

Wiring: Knoll receive 

modules (UDR-Quad 
or UR-Quad) are 

connected to the 

US4-Hub with cat 5 
unshielded wires 

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. Each cat 5 wire run is a home run and wires cannot be 
shared with two quad receive modules. 

 

Connection to stereo video source equipment: Connect the four 
US4 Hub gold RCA jacks with a good quality gold connector four wire 

component RCA jumper cable to the appropriate three component 

output and digital audio output jacks on your DVD, dish receiver, D-
VHS, VCR, stereo or other equipment. If there is a switched 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 US4-Hub comes with a 15 VDC power 

supply. Each Quad receive module requires a Knoll PS1202 power 

supply. 
 

 

 
 

 

 
 

 

 

 
           Note: The quad receive modules can be either  

other components: See documentation shipped with the receive 
units. 

 

Multiple Connection(s): If more than six component receivers are 

required in a system, multiple US4-HUB’s can be connected together. 
To wire together a second, third, etc. US4-HUB, connect the LINK OUT 

of the first US4-HUB to the LINK IN of the second US4-HUB using a 

short as possible tested cat 5 jumper with RJ45 connectors, using all 8 
wires. Connect the LINK OUT of the second US4-HUB to the LINK IN of 

the third US4-HUB and so on. In this example the second and third 

hubs do not have RCA jacks connected but do have their PS1506 power 
supply connected.  

 

IMPORTANT: All of the US4-HUB’s not connected via RCA jacks, but 

with a cat 5 wire daisy chained from another US4-HUB need to have 
their LINK switch positioned in the OUT position. The US4-HUB with 

RCA jacks connected needs to have the LINK switch in the IN position. 

UR receive units do not have any alterations.  
 

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
