Unpacking Your JC 1

Unpack  your  JC  1  from  the  shipping  carton,  remove  the  enclosed AC  power  cord,  the  small 

“L” shaped metal rack mounts, and the gray control wire with a sub-mini 2.5 mm plug on each 

end. (This is the trigger connection wire). While you are unpacking your new amplifier, inspect 

it thoroughly for possible shipping damage. If you see any, contact your Parasound dealer right 

away. Be sure to save and store both the inner and outer cartons and the packing inserts for 

possible future transport. To save
room for storage, you can cut the seams on the bottom of the cartons and flatten them.
