Just set up to record and I picked what sounded like a radio station through the mic. I have never experienced this before. My wife states that she sometimes picks up a radio station on her guitar amp once the guitar is plugged in sometimes. any suggestions? I think it might be the mic cable and guitar cable as they are cheap ones. :voiceover:

Sounds like it. Many cables like that arent shielded against RF or EMI wavelengths. Also, houses with overhead electrical lines can actually pickup RF and EMI and transmit that thru the AC wiring in your house. In my own, my electrical appliances like stereos, TV and even my computer will soundoff with 3 beeps they pickup from local Microwave towers during a system check cycle and those come right thru the electrical outlets. Inline noise limiters and shielded cables should be a standard for anyone doing broadcasting or recording. They cut down this interference substantially.

[center:dvou3uv3]Have you ever experienced a CB radio coming through your speakers when one drives by your house? Happens all the time in my area. Of course, not so often as it used to since cell phones became the ubiquitous devices that they have..[/center:dvou3uv3]

Yes actually. When I had my old Yamaha Sound Mixer board (16 channel) it would pick up CB traffic on channels 6 and 15 respectively and put them out thru my speakers while my band was trying to record. Was good for quite a few laughs at first.

If I may make a suggestion, it might help. Many unsheilded cables connectors are a great source of intereference being picked up. While many of us cant afford the best shielded cables out there, there is a cheap and workable fix you might want to try. There called Ferrite Rings or Tubes. These small peices of iron composite can be found in small plastic clasp-ons. Many computers use very small versions of them to cut down on interference picked up by computer connectors. The same principle could works for UnShielded cables in a Studio Environment. Especially if you have Flourescent lighting as the ballasts give off their own RF and EMI. The Ferrite Rings or Tubes help to cut down on connectors recieving such signals. You simply find the right size (Radio Shack usually has them in stock) clasp it near the connector on your cable. It will help diffuse the signals that the connectors themselves might pick up.

Just a thought!

Excellent suggestion. I know, from experience, that these are very helpful, having worked in the PC and Telecom industry for about 13 years and having battled this demon quite often.

I agree plazma. I've been in the computer/network industry for almost 30 years and have seen these in use in many applications. I have some on my connectors here including on my unshielded phone lines to cut down on interference that picks up. Shielded cables are the best way to go, but these little gems work!

Enjoy!
