vinyl addict Posted March 3, 2016 Share Posted March 3, 2016 How's this for odd. I've owned a Schiit Mani preamp for about a year or so now. Today I flip the receiver on and immediately can clearly hear a local radio station coming in through my speakers. I swapped in an older one I had and it's dead silent. Nothing has moved or changed. I was just spinning Bowie at the Beeb last night and it sounded amazing. Now in all the quiet spots, I'm hearing top 40 hits Quote Link to comment Share on other sites More sharing options...
Sidney Crosley Posted March 3, 2016 Share Posted March 3, 2016 I had weird interference on my phone preamp (Hagerman Bugle 2) when my Apple Airport Express was too close to it, exacerbated when my phone was closer to the Airport Express. I moved the preamp to be on the other side of the amp and have had no interference since - though mine was more static popping than radio interference.

ajxd Posted March 3, 2016 Share Posted March 3, 2016 Had similar issue. Used those in all the unused ones. Fixed it nicely. Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 3, 2016 Author Share Posted March 3, 2016 But why would anything suddenly cause interference? Quote Link to comment Share on other sites More sharing options...
allenh Posted March 3, 2016 Share Posted March 3, 2016 Atmospherics effect radio waves in some very strange ways and change the conditions of signal spread on a very regular basis, ask any radio amateur about Sporadic E propagation especially on HF frequencies That's the correct technical answer but for the easily suggestible then Aliens so get the tin foil out and make sure you save some to make a hat out of.

ajxd Posted March 3, 2016 Share Posted March 3, 2016 ^^^ Also that. Radio station upgrades? Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 3, 2016 Author Share Posted March 3, 2016 Well, I had a RCA noise filter laying around from an old car audio install. Plugged it in between the TT and preamp, and the sound is totally gone. Seems I may need to replace my TT-->Preamp RCA cables. Quote Link to comment Share on other sites More sharing options...
allenh Posted March 3, 2016 Share Posted March 3, 2016 Good point station transmitter upgrades. All cable can act as an aerial except generally when you want it to, also just try some contact cleaner on the connections, if the earth side gets dirty it can do it and you might find just unplugging one end and plugging it into the filter cleaned it enough to get rid of it on it's own. RF noise and breakthough has been giving design engineers sleepless nights for years. Quote Link to comment Share on other sites More sharing options...
Freki Posted March 3, 2016 Share Posted March 3, 2016 ask any radio amateur about Sporadic E propagation especially on HF frequencies But wait for a lull in the party conversation first. ajxd 1 Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 4, 2016 Author Share Posted March 4, 2016 OK, so its not fixed. The RCA noise filter actually filters out the music too? Wtf? I can't hear the TT with the filter plugged in, but no feedback either. But remove the filter and I can hear the TT and the radio feedback. Is the signal from the TT so low that the filter actually filters it out? That's the only thing I can think of to explain it. The filter works normally with car audio.

vinyl addict Posted March 6, 2016 Author Share Posted March 6, 2016 I'm officially fed up with this piece of Schiit. Sending it back and buying a Pluto. Quote Link to comment Share on other sites More sharing options...
Guest Posted March 6, 2016 Share Posted March 6, 2016 I've had zero issues with my Mani, in fact I love it. Great quality for the price. Maybe you got a bad one? Missing shielding? Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 6, 2016 Author Share Posted March 6, 2016 Yeah man, I dunno. I'd be willing to try it again I guess. Not sure what happened. Quote Link to comment Share on other sites More sharing options...
ajxd Posted March 7, 2016 Share Posted March 7, 2016 Did you try the thing I mentioned? The caps? You can also use a ton of cables... but fill every input. Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 7, 2016 Author Share Posted March 7, 2016 I taped off the other unused inputs temporarily and no change. I didn't actually order the plugs. It's really aggravating. Quote Link to comment Share on other sites More sharing options...
xxmartinxx Posted March 7, 2016 Share Posted March 7, 2016 Seems obvious, but have you reached out to Schiit and asked them? Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 7, 2016 Author Share Posted March 7, 2016 Yes, Nick gave me all the recommended tips and what-not. No change. Very depressing. Quote Link to comment Share on other sites More sharing options...
ajxd Posted March 7, 2016 Share Posted March 7, 2016 I taped off the other unused inputs temporarily and no change. I didn't actually order the plugs. It's really aggravating. Tape won't stop em. Go to Radio Shack or Wal-Mart, buy a handful of cables. Plug em in. Check. Return em. Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 7, 2016 Author Share Posted March 7, 2016 I have a shitload of cables. Give me 10 minutes, I'll check it out. Quote Link to comment Share on other sites More sharing options...
allenh Posted March 7, 2016 Share Posted March 7, 2016 You can get rubber caps for the sockets that stop it as well. So you might be able to make something temporarily Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 7, 2016 Author Share Posted March 7, 2016 Yeah, I plugged in a couple pairs of cables. No change. I really shouldn't need to do any of this though. What the hell happened? Quote Link to comment Share on other sites More sharing options...
ajxd Posted March 7, 2016 Share Posted March 7, 2016 Its because you touch yourself at night. I guess this hasn't been asked or stated... whats the receiver? Try swapping out receivers? Quote Link to comment Share on other sites More sharing options...
vinyl addict Posted March 7, 2016 Author Share Posted March 7, 2016 Its a Pioneer, about 5 years old. I guess I can wire it up to my home theater for a minute and see what happens... Aaaaaaand... surround sound interference when wired up to the home theater receiver. I can clearly hear (with no much static at all) a local radio station.
