Simply by plugging it in between two line-level devices, you'll be rewarded with a hum- and buzz-free audio experience. Audio engineers at Sweetwater admire how easy the IceCube makes it to insert an isolation transformer into their signal paths. This isolator comes loaded with a custom USA-made Eclipse transformer that provides a robust low end. Designed to work easily within the -30dB to +15dB range, the IceCube will have no problem handling balanced and unbalanced devices without any distortion. This makes the IceCube an excellent option to use when you can't sacrifice your audio quality. For all your ground buzz issues, Radial's IceCube IC-1 is the solution.Radial IceCube IC-1 Balanced Line Isolator Features: XLR input and output Ground Lift disconnects PIN-1 on the XLR

My dear wife has the ears from hell. As a musician I know that little hums creep into complex signal trains (I have a large pedalboard for guitar) but wifey has no tolerance… “It’s humming! Can’t you hear that? I can’t stand it!”I put the Ice Cube in the line that carries everything to my PA.Aaaah! Marital bliss! ❤️🎶

Pro bass player here.....play many gigs with big pro sound systems, and need to provide a DI out of my bass head. I use the Icecube every time, and get compliments on how great the bass signal sounds.Not only does it isolate the signal (no hum), but it also has the added benefit of smoothing out and improving the sound.How? It is a high quality isolation transformer - which is an inductor, which naturally helps gently roll off very low and high frequencies and buffers transients, providing a very slight *compressor* effect (its power supply equivalent is a *choke* or inductor, which helps cushion the supply from voltage swings). Your sound will instantly improve with the IceCube. Every soundman I worked with loves the bass signal from this thing! Just buy it, and use it on your DI output. It's not just for reducing hum - you will hear the difference - a warmer and more punchy bass sound!

Worked like a charm to isolate studio equipment on one power bar from a dual guitar rig on another power bar. The Ice Cube's ground lift was essential in my case. Using the ground lift of another quality unit didn't work as consistently well.

I had a ground loop that did not look like a typical ground loop. Was definitely related to a usb port in the computer, so it was not a "classic" 60 Hz humm, but it was some high pitched static noise. The intensity of this noise depended on the movement of the mouse and other computer activities. At first I tried to cure it with a usb ground loop dongle which did not work at all. This IceCube fixed the problem. Enjoying clean sound! Used Radial DI boxes a lot in professional live sound setups, always high quality stuff!

Great ground loop solver, I have tried many products such as the ifi usb which didn't work for me. This works, I have used them on a rca to xlr cable to some studio monitors and pc. Easy use just set it and forget it. I only gave it 4 stars because while it works flawlessly there is a similar, cheaper and perhaps better unit. The Art DTI transformer works just as well and handles multiple connections xlr,rca and even trs. Each has its own output as well for only $75 so it might handle multiple instances and outs will have to test.

Just connected the Ice Cube in my audio feed XLR line at the Tampa Convention Center yesterday, punched the little ground lifter button with my screw driver and it worked like a charm removing the buzz.

I tried everything, I assume its part of my motherboard not grounding properly when connected to audio recording gear.I tried several different gear to get rid of the loop, including buying a new interface with a separate power source and even attempting to ground my case with a gater clip/grounding cable. This partially worked.But only and ONLY when I hooked ice cube up between my mic and the interface did it kill the loop entirely.A product that does exactly what it should, easy peasy.Much love radial

Had a buzz in the fold back in our church pa. Had tried all sorts to try and fix - check power circuits, lighting circuits, replaced cables, etc. In the end fitted this and problem virtually gone.

This device feels solid. However, it could not attenuate the hum produced by our sub-woofer. Though, subjectively speaking, it reduced the hum approximately 85%. Packing material was appropriate and the device arrived in excellent shape on the day promised.

This does exactly what it says it does. Tranformer isloated line level XLR connection insert to eliminate hum, and ground loops. I work with translation microphone systems and quite often I get static hum or earth issues even when the audio source given to me is clean. This fixes the problem immediately and I haven't had to use the earth lift switch yet. Great product and quality build. Handy size fits in perfectly with my kit.
