THE FCC REGULATION WARNING (for USA) NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. Feedback is a phenomena that occurs when a microphone is placed too close to a playback speaker; this causes the mic to capture the audio that the speaker is emanating, then play it back through the speaker, then capture it again - creating a feedback loop. Shielding surrounds the power-carrying conductors of the cable and protects it by (1) reflecting signal interference as well as (2) picking up noise and conducting it to ground. Large speaker cabinets such as guitar amps often do not have shielded magnets. Re: electromagnetic interference killed my hard drive? In reply to erik hansen • Nov 9, 2008 Having read all the thread so far and having an RF electronics background, I tend to agree with those citing RF interference with the PC or hard drive electronics as being the cause of crashes etc. I moved back and it stopped.

So can Direct Satellite Service (DSS), 2. In his book, the author. The Result. (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. But even lights and human beings give off some infrared radiation. In some cases, the strong transmitter signal can overload the wireless receiver and cause interference due to intermodulation. The fact that the speakers were powered and not plugged into an audio source answers the question. Follow the steps below in order to pinpoint the cause of engine noise and reduce or eliminate the problem. The distance between the mike and the speakers has a lot to do with the frequency of the howling, because that distance controls how quickly the sound can loop through the system.
