(other than near the powerful TV or Radio broadcast antennas)   For the past year I have had GOOD success with an XLR adapter box for my Panasonic GS500; the device never has failed to adapt audio from any house mixer board, cheap PA systems,  laptops etc. since it has both line and mic. level inputs.  HOWEVER I have been tortured by some very weird electrical interference at least half the time, when using XLR microphones on a 50 foot XLR cable.  I got rid of all cases of RF interference by clamping on multiple Ferrite beads from Radio Shack.  But there is some WEIRD and very loud hum/buzz in many cases (it seems always, when the speaker is near, or operating, a laptop, or perhaps, involving the house light dimmer.  I hate this!!!!   How can i stop it?  It sometimes seems to be a body-effect.  It is NOT a garden-variety ground loop since my cam and XLR box are on batteries. And my microphone is NOT contacting the other equipment.</p> http://www.videomaker.com/community/forums/topic/audio-feedback-recording-to-camera#post-51373 Wed, 14 Oct 2009 04:36:29 +0000 halfpipe 51373@http://www.videomaker.com/community/forums/ <p>Deoxit might clean up all the connectors and help</p> http://www.videomaker.com/community/forums/topic/audio-feedback-recording-to-camera#post-51364 Tue, 13 Oct 2009 17:50:10 +0000 EarlC 51364@http://www.videomaker.com/community/forums/ <p>Dunno Rob, depending on the length and quality some of those cables (Canare, for example) can get fairly pricey. But yeah, for a less-expensive approach over high-brow wireless rigs, it's a way to go. Plus much better quality sound, again depending on the length and microphone at the end, over a "cheap wireless mic setup".</p> http://www.videomaker.com/community/forums/topic/audio-feedback-recording-to-camera#post-51362 Tue, 13 Oct 2009 17:41:29 +0000 robGRAUERT 51362@http://www.videomaker.com/community/forums/ <p>Do you think there is a way you can use a wired mic with a long XLR cable? Not only would that be more reliable, but that would be cheaper, too. And probably better quality. </p> http://www.videomaker.com/community/forums/topic/audio-feedback-recording-to-camera#post-51354 Tue, 13 Oct 2009 10:46:59 +0000 EarlC 51354@http://www.videomaker.com/community/forums/ <p>Sadly, the fault very likely does fall on the shouders of your "cheap wireless mic setup" my friend. When I started out in commercial and public access video production some 20 years ago I did the same thing - picked up a multiple wireless mic system. Some RadioShack-like thing, hoping it would get me by. From day one I had many of the problems associated with inferior and/or cheaply-made electronic gear.</p> <p>When  you under invest in such equipment, while it is possible to occasionally find a gem buried in all that coal, it is usually so full of inferior circuitry, components and elements as to make the actual investment a total waste of money - a black hole for your hard-fought dollars.</p> <p>So, yeah, you wanted to hear answers "besides..." but the only way you are going to be able to combat the huge number of possible reasons technically or signal-wise why your system is experiencing this problem, the major probable reason is the LACK of quality of your "cheap wireless mic setup."</p> <p>Even with some systems that cost you MORE you'll have signal issues, and occasionally those systems in the $1K or higher range will experience a few themselves. There IS NO PERFECT wireless system, though some of the really expensive (Letrasonics (SP?), for one) might come close.</p> <p>Sorry, I have no specific answer or solution for your existing system, but a few of the answers you don't want to hear, in addition to higher-priced and better quality wireless include hardwired mics to a mixer, a hardwired mic pointed at the PA speaker system "sweet spot" and connected directly to your camera, or placement of several self-contained, free-standing digital recorders similar to the Zoom H2.</p> http://www.videomaker.com/community/forums/topic/audio-feedback-recording-to-camera#post-51353 Tue, 13 Oct 2009 09:30:03 +0000 futball8 51353@http://www.videomaker.com/community/forums/ <p> Hello All,</p> <p>I've encountered a puzzling problem as of late. I record city council meetings, utilizing a cheap wireless mic setup - an Audio Technica PRO88 VHF transmitter and receiver. Often times, I get a half-second buzz tone in 5-second intervals. Everything else is clean, but every five seconds, there is a very short buzz that lasts a half-second. </p> <p>The wireless mic is running on batteries and my camera is as well - nothing is plugged into an electrical outlet. </p> <p>Any ideas, besides "buy a real UHF wireless system". :-) Thanks in advance!</p>
