faulkner1953 Posted July 5, 2006 Report Share Posted July 5, 2006 My RH1 came with a whole bunch of these ferrite cores. What the heck is the purpose of these? There's one around the remote cord already, and one at each end of the USB cable. Plus some spare ones! Any point to these? They are a little bulky. I'd get rid of them if they serve no good purpose. Anybody know about 'em? Quote Link to comment Share on other sites More sharing options...
jrv2kgt-s Posted July 6, 2006 Report Share Posted July 6, 2006 OK Class, please turn to page 10 in the Sony MZ-RH1 Operating Instructions booklet. While you're checking out what the ferrite cores are for. Be sure to completely read through the manual. Quote Link to comment Share on other sites More sharing options...
bobt Posted July 6, 2006 Report Share Posted July 6, 2006 You can also search the forum, there has been much discussion.The general consensus though is you can leave them off, they make nice paper weights.Enjoy your toy,Bob Quote Link to comment Share on other sites More sharing options...

I don't know how to search globally. Quote Link to comment Share on other sites More sharing options...
jrv2kgt-s Posted July 6, 2006 Report Share Posted July 6, 2006 Man, you can't kid around anymore. More commonly known as a "choke". The Ferrite cores are an effective means to remove EMI/RF line noise when connecting other devices/components to the RH1. If you are planning on recording via Mic or Line-in, then I would highly recommend using them. Quote Link to comment Share on other sites More sharing options...

faulkner1953 Posted July 6, 2006 Author Report Share Posted July 6, 2006 I never used anything like that when recording by mic with my Sharp. I use a battery box and go through the line in. Is this a common problem? I don't understand how a choke on the remote cord could make a difference, or the USB cable either. Quote Link to comment Share on other sites More sharing options...
bobt Posted July 6, 2006 Report Share Posted July 6, 2006 At audio frequencies an RF choke should have no effects, easy enough to try if you want, make sample recordings with and without the core and see if you can notice a difference, all I can see then accomplishing is shortening the cable a few inches.Reminds me of the audiophiles who used hollow speaker wire because of the "skin effect" of high freuencies!! We are talking of gigahertz frequencies, to use skin effect not 20 khz.Try or don't, I have the prewrapped cab;es and without, haven't noticed any advantage either wayBob Quote Link to comment Share on other sites More sharing options...
mikey c Posted July 6, 2006 Report Share Posted July 6, 2006 I say we just remove them if they bug us. I think? Gosh it's the only USB cable I own with magnetic rocks on each end. I think I'll keep an eye on this topic to wait to see where this goes. Hmm.(hey faulk, I know of that little town called mckinney, i did my music undergrad in denton-neat area that north texas) Quote Link to comment Share on other sites More sharing options...

If you haven't been to Denton or Mckinney in a few years, you wouldn't think it was the same place.And about those magnetic rocks....I already removed mine. Don't see much point in 'em.

bogon07 Posted July 7, 2006 Report Share Posted July 7, 2006 OK Class, please turn to page 10 in the Sony MZ-RH1 Operating Instructions booklet. While you're checking out what the ferrite cores are for. Be sure to completely read through the manual. From the manual:"You must attach the ferrite core to comply with the applicable EMC standards. Be sure to connect them when using the recorder with a computer. If not there is no need to connect them." Sony includes them to say it is complying with a bunch of vague electro-magnetic interference standards depending on which country you're using it in.
