I am getting high frequency hiss / buzz between a musical keyboard and an keyboard combo amplifier speaker. Will puting one on the audio jack lead between the two help?

Asked by: valleyboyo
It may help to fix this.

My car camera interferes with radio reception. Would this ferrite clip help clear the loss of station. The radio works fine when the camera is off or running on battery only.

Asked by: Waldo
I would suspect the problem lies with the vehicle electrical system, or possibly the 12v power adaptor for the camera. I don't think a ferrite is going to he help in this instance.

The radio in my motorhome picks up a good range of stations without interference unless the reversing/ rear view camera is switched on. Then I get interference on all stations. Will a ferrite clip on the aerial lead going in to the radio help with this?

What attenuation does this item provide? Your table shows attentaion in ohms but ohms is impedance! How many dB attenuation at what frequencies? What ferrite is it made from? It is less risky to buy elsewhere as you don't provide useful information!

Asked by: Mr T
Hi, you are correct attenuation should be rated in db, I have asked our content team to update all the Ferrites to the correct standard, this should be completed in the next few days.

To stop HID lamp ballast interference on the car radio, where would these be fitted?

Asked by: Barrie
You may need one on the radio or the ballast, but we would not be able to say as we have no experience fitting it to this kind of setup.
