Unbalanced Input

Use this input if your preamplifier or surround controller doesn’t have balanced output 

connectors or if you simply prefer to use unbalanced connections. 

What You’ll Need:

• 

One shielded interconnect cable with RCA plugs

• 

A source component with RCA output jacks

Before Connecting

 

Leave  the  AC  cord  on  the  JC  1  disconnected  until  you  have  made  all  other 

connections to prevent any surprise burst of sound.

 

Make  sure  that  all  your  cables  are  long  enough  so  they  are  not  strained  or 

stretched once they are connected.

 

Make sure the 

Select 

switch on the JC 1 is in its 

Unbalanced Input 

(left) position.

To Connect 

 

Plug one end of the cable into the 

Unbalanced Input 

jack on the JC 1.

 

Plug the female end of this cable into the desired channel output jack on your 

preamplifier or surround controller.

 

Repeat steps 1 and 2 above to connect additional amplifiers.
