"Hum X", in my experience actually doesn't work most of the time for filtering bad AC.
Furman does make a compact, 2 outlet version of their high-end power conditioner, the AC-215. Don't know about European availability. http://www.furmanpower.com/product/15a-two...itioner-AC-215A Tripp-lite Isobar (again, not sure of EU availability) makes great industrial power filtering/conditioning devices. https://www.tripplite.com/isobar-4-outlet-2...0-joules~EURO4/ *I've had good luck with these in both clubs and on stage where the power is questionable. The power in my neighborhood is 'questionable' and I use the Tripplite isobars in my practice studio. This post has been edited by klasaine: Apr 3 2017, 09:17 PM -------------------- - Ken Lasaine

Funnily enough I work for a company that makes everything from Surge protectors to 3 phase UPS.
You can get an 8 outlet extension with Surge protection and RFI and EMI filtering which will help a little and is cheap http://www.apc.com/shop/pl/pl/categories/p...tchCountry=true and maybe enough, but ideally you want to have something that gives you isolated power and that is usually part of a UPS device which would be much more expensive. It's a shame venues don't have great electrics with a specific circuit for sound equipment. Thomann might have similar to the 8 outlet extension in a rack format. -------------------- My SoundCloud

Don't know about European availability. http://www.furmanpower.com/product/15a-two...itioner-AC-215A Thx for the feedback. I had no opportunity to test hum x by far. My interest is based on information and user reviews from the internet. Your info is priceless - a kind of critical to pass on this device 2-outlet furman is what I have found the best choice by far. Has been on top of my list before writting the post. I was hoping maybe someone could advice something even smaller but I do realize I may end up buying that particular furman model.

I will definitely get into details with those devices as well. The price is in fact worth the interest |

The Hum X is just a glorified ground loop eliminator/isolator. 'If' you're running two amps and one of them is noisy due to ground loop problems - the humx can help that. That's really the only thing it works with. It doesn't filter bad power.
Tripplite makes a 2 outlet surge protec/filter that plugs into the wall. It's about the size of a Boss pedal. https://www.tripplite.com/isobar-2-outlet-s...ight~ISOBLOK20/ It may also be available in the EU. Obviously check if they have a Euro website.

But when i run my sound interface through my macbook i hear a hiss when i connect the charger, once I remove the charger there is no hiss. and this hiss only comes up only when I run guitar sims such as Amplitube or GuitarRig, there's no hiss when I play media files..etc Many (most) consumer grade power supplies can introduce noise into a signal chain. Any and all types of 'digital switching' power supplies are the worst offenders. I doubt the Hum X would fix your hiss problem. The Hum X is a ground loop remover that (in the states) removes 60 cycle hum. The hiss or a high pitched 'whine' is something completely different (regardless of where you live). Sometimes it's referred to as 'coil noise' or 'coil whine'. ANY transformer (or inductor) can cause coil noise. The cheaper and more generic, the more apt they are to do it. https://en.wikipedia.org/wiki/Coil_noise From the Eb-Tech (humx) website ... "The Hum X filters out unwanted low voltage from the ground line that causes hum and buzz while maintaining the ground. Simply place the Hum X on the end of the power cord of the equipment that has (or is creating) ground loop hum and plug the Hum X in to the wall outlet. Ground Loop is gone and audio signal remains intact. Easy to use, easy to install and completely effective."

Well done there! APC stuff is top notch IMHO and I"ve got one myself in rack form as non-interuptable power supply. Sturdy and solid. If you can get them in European spec then BAM! I love the Furhman stuff too. Same goes for them if they come in Euro Spec.
Never heard of these guys but it's euro spec and a bit smaller. http://www.apitech.com/products/16-amp-power-filter Funnily enough I work for a company that makes everything from Surge protectors to 3 phase UPS.
