Reddit reviews Ferrite Core 1/4 Cord Noise Suppressor

is it a good radio station? If so, enjoy :-)

cable may be acting as an antenna, try using a [ferrite core] (http://www.amazon.com/Ferrite-Core-Cord-Noise-Suppressor/dp/B0002MQGE0) to suppress EMI. Make sure you get the right size!

Buy some ferrite cores (check the right diameters), wrap them around the power cable(s).

Sorry it was late lat night when I posted. I have a AudioFire 2, and I found that if I didn't disable the onboard sound in my bios then I would get that sound. Even if OS X doesn't detect your sound (Realtek) it is still active on your motherboard.

I also have now added ferrite chokes to all audio and power lines going in and out of my computer to my amp. This includes firewire and usb cables. I actually bought new firewire and usb cables that had the ferrite chokes already in them, the link from below was for all of my power cables.

I've read that if you place your phone on tin foil, it will alleviate some of the noise (this may affect your cell service, though). Also, try putting a ferrite noise suppressor on the power cord of the alarm clock. You can buy them on Amazon.com or just take one off an existing USB or power cable.

I'm using a 2i2 and not having any issues like this. I just tested it, and even with using a Shure SM58 (very different mic, SM58 is a vocal mic) and plugging in my acoustic electric the first few seconds of the track are completely silent on both channels.

I'm not much of an expert here but you may have either electronic or literal background noise. I used to run a Dean Markley Soundhole pickup to amp my acoustic guitar and it would have interference, and I just picked up a couple of ferrite cores from RadioShack for like $5. They seem like some kind of magic, but the magnetic ferrite core just snapped onto the line cord fixed my problem. You can find them on Amazon for like $4.

The second thing may just be the fans on the laptop or anything else in the room. I'd try changing the power settings on the laptop to low power, that uses less energy and will spin the fans at lower rpm making them quieter.

Finally, I'd try the Line and INST selector switches as I think that might be part of your problem. I'm not much of an expert, but here's the manual page on the two options.

> The front panel input sockets are Neutrik Combo®, which accept either an XLR male connector (you
will probably have one on the end of your microphone cable) or a ¼” (6.35 mm) jack plug. Note the
Scarlett 2i2 has no “Mic/line” switch – the Focusrite preamplifier stage is automatically configured
for a microphone when you plug an XLR into the input, and for a line or instrument when you connect
a jack plug. Set the LINE/INST switch next to the socket to INST if you are connecting a musical
instrument (a guitar in the example) via an ordinary 2-pole (TS) guitar jack, or to LINE if you are
connecting a line level source such as the balanced output of a stage piano via a 3-pole (TRS) jack.
Note the Combo connector accepts both TRS and TS types of jack plug.

I'm fairly sure if you're using the SM57 mic it's using an XLR connector, what you definitely don't want is some kind of adapter that changes it from XLR (the three prong cord) to a 2-prong TS or TRS jack. XLR is a balanced cable and shouldn't have as many problems with interference. It seems like with XLR it doesn't matter what the selector switch is set at.

Hope this helps, good luck.

Random shot in the dark, but...

Get yourself pone of these (or something similar - can always yank one off of an old power cord too) and wrap the USB wire through the center of the core twice.

Its possible there's some interference traveling down the ground wire/shield and into the speakers even if its not an analog audio connection.

Try a front USB port instead of a back one, or vice versa.

There is also the possibility that the card is dragging the system down and not giving the USB chipset enough resources to handle the audio stream. Try updating drivers for the USB device as well.

I'd like a solution too. I've added ferrite cores (https://www.amazon.com/Ferrite-Core-Cord-Noise-Suppressor/dp/B0002MQGE0) to the supplied audio cable and I still get hissing and popping.
