I have wireless speakers (RCA Model RC-070 with Power Line
Transmitter) that ONLY work when the POWER CORD FOR THE SPEAKERS is plugged into the SAME electrical outlet as the POWER CORD FOR THE TRANSMITTER. If the speakers are plugged into an outlet that is different from the outlet for the transmitter, the speakers do not work. If I plug the speakers into a power strip that is on the same outlet as the transmitter, the speakers work. I have tried a variety of electrical outlets (same outlets for both and different outlets for each) and I get the same result. I have concluded that, for some reason, the speakers and transmitter must be plugged into the same electrical source(outlet). This problem defeats the purpose of the wireless speakers that I want to put in a different room from the transmitter. Does anyone have any suggestions as to the problem and how I can correct it? Thanks. |

Thanks. Look at the X-10 line of modules. There is a module to connect across the two 120 VAC lines to couple the RF to the other line. -- Service to my country?

Michael,
Thank you for the quick reply. I know that it is difficult to put a technical solution in lay person's terms but it would help me if I understood the terminology. If you have time, is it possible for you to explain why these speakers/ transmitter have this problem and how your solution will solve the problem. I am not familiar with electronics so I do not know what is an "X-10 line of modules" and I do not understand the "120 VAC lines to couple the RF to the other line." Again, I appreciate the information. Lin |

Try the top and the bottom outlets in each case. Does the result differ? |

I tried many, many different combinations, as Homer suggested. After
I tried those combinations, I saw Don's response. Based on all the combinations, I finally concluded that the "Power Line Transmitter" AND the speakers must be plugged DIRECTLY INTO ELECTRICAL WALL OUTLETS. If I plugged the "Power Line Transmitter" into a POWER STRIP (SURGE PROTECTOR) and the speaker into a DIFFERENT electrical wall outlet (not the same wall outlet as the surge protector), the speakers did NOT work. If the speaker was plugged into the wall outlet that contained the power strip with transmitter, the speakers worked. I think I have discovered how to make it work properly, thanks to all your suggestions. My other wireless speaker system works fine but this one was problematic. I do have a couple questions that are more out of curiosity: 1) Was the surge protector related to the problem? 2) Does the "power line transmitter" work differently than other wireless speaker transmitters? (does one type of transmitter send radio waves and the other type send the signal through the power lines? Thanks to all of you for your assistance. I am a heavy electronics user but I lack technical knowledge of electronics. Lin |

It also removes any RF from entering the power line. -- Service to my country? Been there, Done that, and I've got my DD214 to prove it. Member of DAV #85. Michael A. Terrell Central Florida |

@n59g2000hsh.googlegroups.com: Michael, Thank you for the quick reply.

Again, I appreciate the information. Lin Simply put, those speakers are sending the audio on the electric wires in your home, over an RF carrier. X10 controls do the same thing. X10 is basically light and appliance control system that sensd signals from a keypad or other controller, over the powerlines, to receiver modules that control lamps or appliances. Typical North American homes have their electronic service coming in on two 120V lines from opposite sides of the utility trasnformer (which don't carry over the powerline RF, typically), sharing a common neutral. What could be happening, is the other outlet is on the other 120V supply leg coming in, than the outlet the transmitter is. A passive X10 bridge (which is essentially a capacitor that couples the on line RF signals from one leg to the other) may work. It could also be one outlet is too far from the other, electically, or there is a filter somewhere blocking the signal. |
