Unpacking Your A 52

Unpack your A 52 from the shipping carton, remove the AC power cord and the control wire with a 2.5 mm sub-mini 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.
