TYPICAL 6 ROOM INSTALLATION

NOTES ABOUT HUM:

While the MA1240 has been designed to minimize the possibility

of hum in the audio 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 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.

Important Safety Instructions

To reduce the risk of electric shock, do not remove cover. No user service-

able 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 120V operation. Be sure to change the fuse

(4A rating) before switching to 230V operation.
