NOTES ABOUT HUM:
While the SPA500 has been designed to minimize the possibility of hum in the subwoofer system, it is still possible that a hum
will occur in rare circumstances. Its safety grounding can create a path for small amounts of 60 Hz energy to travel trough
the line-level audio system. While not dangerous, this energy can cause diffi culty with the subwoofer auto signal sensing
circuit, and at the very least will interfere with the quiet enjoyment of your system. The fi rst course of action should be trying to
make sure that all of the audio components are connected to either the same electrical outlet, or at least into the same circuit
branch. Next, cable TV systems are notoriously the culprit, so be sure to try disconnecting all coaxial feeds that are connected
to the system. If this solves the problem, install a coaxial line isolator and reconnect the system. In the very worst case, a line-
level audio isolator/transformer connected to the line-in of the subwoofer amplifi er will usually solve the problem.
IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of electric shock, do not remove cover. No user serviceable parts inside. Refer servicing to qualifi ed personnel.
To reduce the risk of fi re and shock do not expose unit to rain or moisture. The unit should be connected to an earth grounded AC
electrical socket. The unit should be operated in a well ventilated area. Minimum clearance is 2 inches from the ventilation openings.
Note: Unit is set at the factory for 115V operation. Be sure to change the fuse (5A rating) before switching to 230V operation.
