I'm not that smart, why do I need a EMI/RFI filter? What does that do? Thanks!

Sometimes electrical lines will pick up noise from other electrical devices, EMI electromagnetic interference, or radio frequencies, RFI, that can affect devices plugged into the electrical outlets the EMI/RFI filter is to help keep this from happening.

No, it's not. No need to pay for shielding unless you are running cabling near strong EMI sources

Thank you so much for your response. When it comes to electronics equipment, I am clueless. Your response was easy to understand and was very helpful.

Those are basically different bandwidth ranges. They are important to know if you already have a treansmitter and are replacing a microphone ore vice versa. The other important thing is if you are accumulating a lot of wireless mics you may need to vary the ranges to keep the transmissions clear.

There is no surrounding or electrical noise. You may pick up something if you are directly under a high powered electrical line. Then again, you will here EMI noise w/wo anything on your ears.

Well some noise is normal and that seems to be what you have going on. If your near a computer or router or any fluorescent lights you will get some EM interference. And that is what it sounds like in your video. You can buy a cheap noise gate and set the threshold to say -75 db and that will clean all that up.

If you believe one of your plug in electrical devices may be interfering with your home automation system this filter will block the noise from that device so that your home automation system will not be affected by electrical noise on that leg in your home electrical system. It will only work if a device is indeed causing the problem and if you plug the actual offending device into it. If you believe your laptop is the actual offending device causing the electrical noise then it should work.

No extensions for this that I'm aware of. This is just a guess, but there might be similar products that use radio frequency.

This only filters noise from the device that is connected to the Filter port. For example, I use one on each UPS.

I can't be certain, however a sound card via usb should kill all EMI since it's a digital connection via usb. EMI should not be a factor.

Mm i'm not shure but i don't think that this cable could eliminate the RFI captured by your mic... Nevertheless this is an incredibly low noise cable. You feel like the sound of your instruments come surprisingly from the dead silence!

Yes Thomas, you should definitely use filters to filter out other sources (some known and unknown) of interference.

You don't need a RF ground, but the grounding/lightning arrestor adapter is always a good idea to keep lightning out of your radio shack and bleed off static electricity.

Welcome. Glad to help. The performance to cost ratio on this RF transmitter / receiver pair is exceptional, in my opinion.

Less than 2"; don't know what IC rated at? Large FM radio interference when it is ON.

I assume you mean electromagnetic interference. I have read about this from cheap electronic ballasts but this one is awesome. I have had in no way any interference from this ballast. Radio, Internet, air television is all fine.

The unit uses frequencies in the range of 4-36 mhz to operate, so if that range can couple to the other units, this is a valid concern. There is a frequency splitter built into the unit, so not much signal should get past that, so it might be ok. If you add another filter and/or amplifier in the path into your unit you can pretty prevent any leakage. I didn't measure how good the built in filter is when I was checking out the unit, since I wasn't running any other service on the cable.
