Parasound HCA-2200II
Product Advisory
Your Parasound HCA-2200II uses a grounded AC cord. For most systems, this will give optimum perfor-
mance.
However, with some systems a 60Hz hum may be audible. (50Hz overseas)
This does not indicate a fault with the HCA-2200II
It often happens with the most expensive high-end components that are equipped with grounded AC cords.
If you think your system has this problem, the first step is to reverse the AC plugs of your other components,
one by one, starting with the preamplifier. In many cases, this will eliminate the problem.
If this fails to cure the hum, it will be necessary to reverse the way the AC plug of the HCA2200II inserts into
the wall socket.
Please do not cut off the HCA-2200Il's 3rd ground prong on the AC plug; if you move or change other
components, the ground prong may be needed to reduce hum.
The preferred way is to purchase a low cost plug adaptor (available at any hardware store)
which has a three pin socket to accept the 3 pin plug of the HCA-2200II But it has only two pins of equal
size, so it may be inserted either way into your wall socket.
Using the AC plug adaptor (sometimes called a "cheater") in no way compromises the safety or sound
quality of your system.
