I use this when my Headrush Pedalboard’s direct XLR out is allowing too much interferenc. It silences that nasty noise. I don’t know how or why it works, but it does and only requires one extra XLR cable to patch it in (I use a 2 ft cable).

These boxes are good build quality and contain a transformer, which eliminates many ground loop problems. They do not appreciably alter the sound. Most "ground loop eliminators" do not have a transformer. These do. They are worth the money.

I often need to run an audio reference signal from my mixer to the mic inputs on my camcorders so I can synchronize clips from different cameras using a common audio track. When I'm recording the audio tracks separately the camcorders don't need stereo. A common mono track functions as a time code.When my camcorders use a power supply, connecting an external signal creates hum and noise. The ISOBLOX did not help. A passive direct box (DI) used in reverse worked very well but required an attenuator and adapter cords. I'll explain below. I used the Rapco DBBLOX DI which is inexpensive and the same size as the ISOBLOX.The DI has a male XLR connector that is normally an output. I made an XLR-F to XLR-F cable to use that as in input. I also used an XLR attenuator to reduce the mixer signal by 20-30dB before it hit the DI.The DI has a 1/4 mono jack on the other end. I used a cable that converted 1/4 mono plug to miniTRS mono plug to feed the camera mic input. That cable connects the tip and ring of the stereo mini plug to the tip of the 1/4 mono plug.The transformer inside the DBBLOX rattle around just as it did on the ISOBLOX. I was able to solve that by taking off the top of the box (upper screws on each end) and placing a small piece of foam over the transformer to hold it in place.

This item is just as described and has help with the audio for many conferences that we record. There are times where there is interference with the cables from lighting or other things and it causes a buzz in the recording of audio. With the isolation device added it either gets rid of the buzz completely or drops it to a level that we can take out in post production.

It breaks up ground loops with a 1:1 600 ohm transformer enclosed with an extruded aluminum enclosure. There appears to be no other components inside. Keep it away from AC cords and other magnetic fields as it has little shielding. The transformer rattles around inside so I take some adhesive like Goop and squirt some inside. I keep these transformers in my professional audio problem-solving kit as they are low price, pure function, and take up very little room. Sure, there are much better at 4 times the price, but these handle all but the toughest 'pin 1' problems. I would buy again and again, but keep the glue handy to tame the little rattler inside.

I was about to write a 5 star review on this product as I was check in it I connect it to one of my powdered Speaker's and check the volume wow it kill the sound most of those speakers have. So I tried on my other speaker and thinking to order 1or 3 more since it was awesome., suddenly it stopped working and very,very low sound came out of my 2nd speaker I checked all connections and was all right 1rst I thought it was my speaker until I remove this ISOLBOX out of the line and connect the speaker direct to the mixer and the speaker was perfect so I tried this ISOLBOX with my others power speaker's just to find out it did exact the same to them very,very little noise out of each one even on high volume. So yes it worked for like 10 minutes. Now I have to deal with return which everyone knows is a PAIN hopefully I get my money back. I can see more low rating reviews on the future on this item

Used in quelling buzz in a mal-installed venue where power amps were on separate circuit from FOH and monitors.I did not expect this reasonably priced device to come in such a "together" package, which has Neutrik XLR connectors and very solid metal case. You will need a short (XLR-to-XLR or XLR-to-TRS) cable to connect to the receiving device for best use - and the shorter the better within reason. Do consider that while purchasing this.Note that these are good at what they do, but not magic. That is, they will eliminate hum/buzz that is due to "pin 1 problem" (ground loops) in the connection in question. If you have noise on the line _before_ the given connection, you will have to trace it back to its source and solve it there.

We have 3 pairs of powered JBL Eons and we use them in large tent along with some stage lighting. Even after routing all the power cords and audio cables separately, we were still getting a pronounced hum when the lights came on. We rented two of these and stuck them in line right before the main speakers, and .... Nothing! Complete silence! I purchased a few of the since and have been very pleased. Take note, though, phantom power will not pass through these.
