Your cart is empty.Housed in a high impact nylon casing, the Whirlwind ISOXL outperforms the industry leading inline isolation transformer. This is a professional quality compact transformer in an XLR male/female tube for quick fix line isolation. The shield is lifted from input to output.

These seem well made to me, though I don't know where the transformer comes from. Could be an OEM USA or elsewhere, but it seems to keep the integrity of the signal. I use these in my studio between my interface line outs and my monitoring station. They have taken the significant noise I had down to nil. Testing back and forth it seems to me that the signal is 95-99% intact sound wise. The only product I would imagine to do better in this regard is the Jensen P0-2XX. Their transformer designs are the most incredible in existence, in my opinion, for audio applications requiring transparency. That unit is also $135 per channel. These Whirlwinds are only $48.I also use these to block DC phantom power that might accidentally be turned on when using a channel strip as an insert in a mixing session. Fluke tests confirm that the transformer does indeed not let phantom power DC through, though I don't know the stress factor on the transformer of the Whirlwind nor the output of the channel strip at that point. I would rather they be stressed than the capacitor coupled outputs of a very expensive interface.

I switched my home theater over to XLR connections from my processor to amps and subwoofers hoping to reduce hiss and ground loop noise (a big issue in a system running across four dedicated AC circuits). I had been unsuccessful in mitigating these issues with RCA connections to my subwoofers with a variety of products. XLR connections almost got the job done by itself - all that was left was a faint hum that only occurred when my projector was turned on with an HDMI connection to my processor. I initially tried using ART transformers that I had on hand on the inputs to the subwoofers but they still left a faint hum that was audible from my listening position 12 feet away. It was not too distracting but I tried these to see if they could do better. There is no trace of hum that I can hear with these and I am now experiencing the lowest noise floor that my theater room has ever had.

complete waste of 50$ the hum on my sm7b sounds even worst with this product. Don't waste your money!

small and simples, does the job, and is by a quality company

Well...if i were to judge its effectiveness from 1 to 10.....10 being perfect. I would say its effectiveness is a 7.5It did indeed knock out the majority of hum as a result of a system gnd loop, but not completely. This is very difficult to do though. Would recommend.

They're a little expensive, but if your frustrated with that radio frequency buzzing coming out of your PA speakers, these isolators do the job of affectively removing that annoyance. A couple of these in my front of house speakers really cleaned up the noise. They're WELL worth the price.

I just received my Whirlwind ISOXL. I haven't tested it yet, but it will probably work fine.My complaint is about the poor level of quality control on the item. The barrel is plastic, and the item was shipped with the molding "flash" still all around the ends of the part. I worked in a plastics injection molding factory in college, and JOB 1 was to remove the flash from the molded parts. Nobody had done this on this part. Frankly, at first I thought the part was molded incorrectly or distorted.Also, I agree with the first reviewer that the plastic appears to be of flimsy quality. This thing will most likely work, but I am done with Whirlwind. The prices are premium and the quality is minimal.I truly try very hard to buy American. However, when I see an American-made product like this, at a premium price, but at a very low quality, I really wonder why.I trimmed off the flash, and, against my better judgment, I will keep the part.C'mon guys! Take a look at the stuff you are shipping!!!!

This is an audio transformer that provides galvanic isolation. It also interrupts the ground connestection (pin 1). The transformer windings are shielded. It is useful for connecting balanced to unbalanced device. Unbalanced connections (different impedance to ground) can turn common mode noise into normal mode noise. This transformer fixes that, if you put it close to the unbalanced side.Often, just interrupting the ground/shield at the destination end works as well. Shield interrupting devices are a lot less expensive, try that first. Note: it's an isolatolation transformer.-- it will not pass phantom power.
