NOTES ABOUT HUM:
While the SA1000 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
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 amplifier will usually solve the problem.
