entee Posted July 25, 2004 Report Share Posted July 25, 2004 Hey there, all. My first post! I just received my MZ-S1 (sports) minidisc player last week, which included a Ferrite Core (shaped like a large capsule). There were no instructions on how to use/connect this core. What's the purpose of the ferrite core? Do I need to connect the ferrite core to my headphone or ac adapter? Note that my MZ-S1 has no mic input. Thanks, Tee Quote Link to comment Share on other sites More sharing options...
me Posted July 26, 2004 Report Share Posted July 26, 2004 They clip on the AC adapter to reduce interference (it's an inductor of some form). Just clip it somewhere near the plug of the adapter and leave it. Quote Link to comment Share on other sites More sharing options...
entee Posted July 26, 2004 Author Report Share Posted July 26, 2004 Thanks 'me' for helping me with the ferrite core connection. I had previously called Sony's technical support and after much MUCH waiting (I could hear them frantically searching their computer databases for info), they finally said that they could find no supportive subjects for such a device. I then asked to speak to a supervisor or someone more 'technical' savvy. A supervisor then advised that I NOT use the ferrite core at all since it's not mentioned as an included accessory on their computer list. That is, they were clueless. I'm quite disappointed with Sony's tech support. They certainly didn't come across as very knowledgeable. Quote Link to comment Share on other sites More sharing options...
me Posted July 26, 2004 Report Share Posted July 26, 2004 I suppose they're meant to be clipped on already. I wouldn't trust Sony tech support with an included accessory either. They'll probably just read the manual to you. Quote Link to comment Share on other sites More sharing options...
Mystyler Posted July 26, 2004 Report Share Posted July 26, 2004 Nah - I've always recieved my ferrites unclipped. It is quite simple to put on - just run the cord through it, then loop the cord once around the core and back through. Then clip together.

Dr_What Posted July 26, 2004 Report Share Posted July 26, 2004 Do we need the ferrite cores though? The NH700 I bought recently had one attached to the remote control(!?) and there were 4 or 5 others in the box with fitting instructions. Surely that's overkill...

skyther Posted July 26, 2004 Report Share Posted July 26, 2004 Eh? You only need ferrite cores in the power supply cable... Quote Link to comment Share on other sites More sharing options...
me Posted July 26, 2004 Report Share Posted July 26, 2004 I would hate to think what an inductor would do to the sound quality.. I don't know. It's probably fine. Perhaps it reduces the errors that those remotes tend to make. (RM-MC11EL etc, skips two tracks instead of one and other weirdness) Quote Link to comment Share on other sites More sharing options...
Dr_What Posted July 26, 2004 Report Share Posted July 26, 2004 I took the damn thing off (the remote) - perhaps it was put on by mistake by some over-zealous Sony factory worker. As I say, they're handing these things out like sweets... Quote Link to comment Share on other sites More sharing options...
jadeclaw Posted July 26, 2004 Report Share Posted July 26, 2004 A word about the ferrite cores: Europe has much tighter regulations about spurious emissions. You could leave out the cores completely and it will still fulfill the US FCC-regulations. For Europe, insert one in the power cable, another one in the line in cable and a third in the cable to an external amp/Hifi system. The cores should be close to the recorder, a few centimeters away is ok. The cable should be looped once around the core like MyStyler described it. The remote/headphone doesn't need a core, as the rules require conformity with a 2 meter wire attached to the unit. However, you might need a core around the headphone cable, if you record off a sensitive shortwave radio. In that case, a second core around the LineIn cable close to the radio might be necessary as well. On the other paw, the problem might be not existing at all, my R37 for example radiates nothing at all, a Yaesu FRG-7 and an Uniden 2010 showed no additional noise at all, but as usual, YMMV...

skyther Posted July 27, 2004 Report Share Posted July 27, 2004 Ahah indeed matey. So you've gotten both a NH600 *and* a NH700 aye? Quote Link to comment Share on other sites More sharing options...

The ferrite core on my brother's NF520D was also attached to the remote control... *giggle* Stupid, ne? I would've stolen it and put it on the power cord for my N10's AC adapter, but there is already one attached to the wire. >.>; Quote Link to comment Share on other sites More sharing options...
skyther Posted July 27, 2004 Report Share Posted July 27, 2004 You don't need ferrites on wallwarts, it's DC. Quote Link to comment Share on other sites More sharing options...
Mat Posted July 28, 2004 Report Share Posted July 28, 2004 I recieved ferrit cores on my N1's DC cord. However i removed it when i got the unit and never used it again. The units are working fine with the DC in & all... But the adapter im using is the one which i got with my european R90, the N707 & N1 are from the USA. That adaptor did not arrive with an FC so im guessing its not needed for european adaptors? Quote Link to comment Share on other sites More sharing options...
