fi tted in line with the coaxial cable feed. Contact your cable company or your Sunfi re Dealer for assistance.
•Disconnect all connections from the TGIII to your TV.
•Disconnect any component which has a grounded power cord.
•If the hum persists, disconnect all the source components one at a time from the back of the TGIII, until you identify the source of the problem.
•Ground loop isolators are avail- able for audio lines and video. You can ask your Sunfi re Dealer for assistance.
•If the amplifi er has the option, use balanced connections.
•Disconnect the amplifi ers from the TGIII. If the hum persists, try moving the speaker cables away from any power cords. Try just one speaker, connect- ing it to different channels and see if an amplifi er channel is bad.
•An audio cable may have a bad shield
•If you are still having a prob- lem, remember that Sunfi re’s dealers and technical support staff will assist you.
Other causes of noise
•Speaker noise may also be caused by interference or noise on your AC line. Make sure there are no large ap- pliances sharing the line, or halogen lamps or
•Try connecting your system to another AC socket on a sep- arate line.
•If the hum is heard from within the amplifi er and not through
the speakers, this may also be caused by interference on the AC or DC lines. Some amplifi er transformers will turn this into an audible noise. Internal hum can be made worse by a shelf or cabinet resonating, so try moving the amplifi er to another shelf.
•Try moving your TGIII further away from your amplifiers. There may be some effect from the strong magnetic fields which surround the amplifier’s power transformer.
•Try moving your components further away from the TV, espe- cially if you ever notice the screen has changed color in the area closest to the compo- nent.
•If you have very high effi ciency speakers, these may show up noise which other speakers may not. If your amplifi er has gain controls, you should turn them down a little to reduce the noise. Remember to repeat the calibration procedure so all speakers are playing at the same level.
