hissssss

[hig4s]

The his in my helmet is really starting to bother me. I've noticed it since day one on the bike, if I have my helmet plugged in I get hiss. I like to be plugged in so I can switch to helmet speakers at freeway speeds to hear the stereo. At lower speeds I leave it on speakers. I have the intercom volume at 0, and it doesn't matter if I have the radio going to speakers or helmet there is a hiss. My wife says she hears it too, but she has a physical volume control back there and will just turn it to 0 and it goes away. (If I want to talk to her I tap her on the leg and she turns her volume back up.) But the only way I can get rid of mine is to unplug.

 

Has anyone figured out how to solve this? One thought I have is to find an actual volume control that will plug in between the helmet and the bike, but as of yet I have not found one.

I've never heard of this before. Especially with the intercom volume at 0. Maybe one of the electronic gurus can help with this.

It could be a few things...

 

When I switched out my radio (replaced my original 01 unit with a re-manufactured one dated 07) I picked up something similar. A possible source of what is being heard is a result of electrical interference (loosely speaking anyways), or the radio picking up and amplifying an induced current from the fields put out by the ignition system (and the rest of the bike's electrical system) that results ins a constant 'noise' output to the headset. One thing to check is to make sure that the audio cables running from the back of the bike to the front of the bike are as far away from and perpendicular to the ignition cables (spark plug wires) at any point of which they cross. It is possible that mic mutes may help this but I do not know for sure what they do in particular so you may want to do some searching on that too.

 

This is just a possible cause for the static/noise that is heard through the speakers, I do not guarantee that this IS what you are hearing or not, but based on your description and my experience with my radio - I am making an assumption that what you have called a 'hiss' is what I hear as well.

 

Good luck friend, hopefully someone else will chime in with more information too

 

 

Oh yea, Mine is only apparent when I am idling at a light or going very slowly.... But my hearing is pretty bad too...

Peggy and I experience the same hiss. When we turn down the intercom volume

the hissing does get reduced. I was told it is because the mic's are always hot!

I guess you can get a set of voice activated mic's I'm not sure what it would cost for the voice activated mic set up .

I looked up the mic mute for the yamaha and it is $139.00

I had real bad noise coming through my headsets, but I installed the mic-mutes and problem solved... One of our members makes and sells them, I did not pay any where close to $100.00 for mine. Maybe the member will see this and speak up, or you may have another problem. The cables that yama used for the bike are not sheilded, thus the noise, if you pull your tank, you can see where they are run, and like said earlier, make sure you seperate the cables from others the best that you can...

 

Good luck and let us all know what you come up with.

I installed the mic mute at maintenace day. On my bike it eliminates all of the noise when muted except for one. I get a ticking noise even when my mic is muted. If I turn down the IC volume it gets rid of the ticking. I was coming back from Daytona last weekend and when I turned into a restaurant the ticking quit. After I left the restaurant I was going down the highway and hit a bump in the road and the ticking starting again. I can't get it to stop. Back to the hisssing. I think a mic mute would stop that.

I have very good hearing so the littlest noise can drive me crazy, and and it's not a long drive. Hmm, because the mics are hot, that make sense. Thanks for the input, helped me search the right direction and I found this and think I'm going to try it. It's a bit cheaper then the mic mute.

It is headset speaker and mic volume control..

Another option

I also have the Mic-Mutes. They're great for removing ambient noise when you're not talking. The Air Rider and similar are a great low cost alternative.

The spark plugs generate rfi (radio frequency interference) which gets in to nearby audio equipment. the resistor plugs and resistor plug caps help somewhat with this. The stator (generator) can also create lots of electrical noise. The design of the audio system should also filter as much of the noise out as possible also. Generally more expensive audio systems do a better job of filtering out noise than cheap ones.

 

A bad ground, ie: loose or corroded connector can contribute to background hiss in instrument amplifiers, and I presume that is also true on the RSV.

 

There are shielded cables available which have a metal sheath surrounding the internal wires and tied to ground, that can reduce external noise getting into the system. ie: the headset cables can act as an antenna.

 

Checking that all the ground connections have 0 ohms resistence to the bike's frame from pins and connectors is probably the easiest place to start if you want to troubleshoot it. A $10 volt-ohm meter from Walmart is all you need, and this is a good tool to add to your tool kit anyway.

It is not RF,, had a little of that too, but found the weak ground and fixed it.

 

I decided to order the volume and mic control I posted the link to..

 

So I order that, passing lamps and mount, the passing lamp spacer, I also decided to order a carbtune. And last week I added a Stebel horn, and Kuyrykan highway pegs.

 

So far it has only cost me $1,800!!!!! Of course $1,200 of that was for the new refrigerator my wife wanted.

 

OK, I wanted it too.

:think:Didn't you start out looking for something cheaper than mic-mutes ? Can't hide money. Where did I put that sarcasm font , shouldn't it be universal.
