NOTES ABOUT HUM:
While the SA230 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 difficulty with the subwoofer auto signal sensing circuit,
and at the very least will interfere with the quiet enjoyment of your system. The first course of action should be trying to ensure
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 amplifier 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 qualified personnel. To reduce the risk of fire
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 to a 2.5A rating before switching to 230V operation.
