Radio interference
I am having some problems with radio interference when recording on my Korg D3200 mixer. I have good mics, new XLR cables and am plugging into grounded outlets. It is a local AM radio station that has the transmitter about 2 miles away. I have also had problems at another location much further away (probably another station). It seems to be related to the XLR cables. I plugged a Sony ECM 44b lav directly in to the mixer and did not have any radio pickup at all. I thought that XLR cables were shielded to prevent this problem. Is there anything that I can do about this? I cannot afford to have problems in the field.
Regards, Jerry |

Jerry,
Neutrik EMC Series connectors may help. There are some good papers on RF problems and dealing with them on Jim Browns site. http://www.audiosystemsgroup.com/ Look at the papers on pin 1 problems and understanding RF interference. Sam Gates |

So-called "quad" xlr cables may help. They resist RF somewhat better than a standard cable.
Most of the major manufacturers have them, they have 4 conductors (plus shield), in two twisted pairs that are then twisted around each other. Then each pair goes to a pin. This is a lousy explanation, you'd find more info at http://canare.com/files/Cat11_p35.pdf. |
