Wanna know how noisy your AC is ?


Would you also like to know if your "AC treatments" are getting rid of the majority of noise ? Well, now you can : )

I'm going to set up a small "AC analysis kit" that will be available on a "borrow as needed" case. It will consist of an Audioprism AC Line Sniffer, an AC Polarity checker and a multimeter to verify "most proper" polarity of your components in terms of chassis ground / power cord orientation. To make things easy, i'll probably type up a brief set of instructions on how to use the Sniffer and the multimeter. The AC Polarity checker is a no-brainer, so no notes needed.

If you are interested in borrowing these, please respond here and i'll try to work out a schedule. This will only be going to people with positive Agon feedback and / or a very consistent history of posting here in the forums. I realize that some of the contributors here are not consistent buyers / sellers of gear and would not want to disregard them for that reason.

Obviously, this will be done on the "honour system", so i'm trusting in you to use them and return them in the condition that you received them AND do so on a timely basis. Borrowers of this "kit" will be responsible for insured return shipping. If there are enough people interested, i'll set up some type of rotation so that you can ship to someone relatively close. This will keep costs down to a bare minimum for all involved.

Sound like a plan ? Sean

Almost forgot. I can include a "Kill A Watt" voltage & amperage measuring device and an Elfix device that checks for AC radiation. Both are handy devices and weigh next to nothing.

The Kill A Watt can show you how much current each device that you have is pulling individually and measure the voltage at the wall. If the device is shown to be rated for 35 watts by the manufacturer and it is only pulling 15 or 50+, you know that something is wrong and needs attention.

The Elfix can be used to check how much AC radiation you have coming out of various cords / components. It can also be used to orient your power cords / interconnects for reduced coupling. You might be amazed at how much AC radiation there is coming out of various power cords and components. Placing an interconnect within the AC field will actually modulate the AC signal into the signal path on the interconnect.

I may also include an adapter that would allow testing of a power cord by itself with the AC Sniffer. This would allow one to compare the results of plugging the Sniffer right into the outlet and then into that same outlet but fed via the "fancy" power cord. One could then literally hear if there was an audible reduction in noise using the "high dollar" power cord or not. My guess is that there will be a lot of "upset people" if i include this adapter and they check their "mega-dollar" power cords. Sean

Wow. Got a lot of responses here. That's good : )

Marty: As to the question about the Elfix, that tool appears to be similar. While the Elfix has a control to vary the sensitivity, it costs quite a bit more than the one shown on the Lowe's website. Then again, it is "audiophile approved". Thanks for pointing out an alternative that offers great "bang for the buck". I like those kind of deals : )

As to the instructions, this is something that i'll have to work on. I have no problem with making them available to the general public for those that already have the necessary tools. This may take me a few days though as i have nothing typed out at this point in time.

Since we have a quite a few people interested in this, how long of a "visit" should we allocate for each person to have these tools ? Bare in mind that performing all of this work will involve disconnected ALL of your cables from your system, so one should take this into account prior to the "kit" arriving at their house. If this means that you have to come up with some way to identify which interconnects go where, what direction they face, etc... having a plan of attack will speed things up.

How about if i start working on a list of directions and then post them when i get them done ? This would allow folks a chance to see what is involved and whether or not they are up to such an "audio challenge". While my guess is that most people that are posting / reading on this forum are pretty "avid fanatics" about their systems, some folks are not quite as eager to get their hands dirty or break a sweat. This may help reduce the number of folks on the list and save us all a lot of wasted time. Just be patient as it may take me a few days to come up with directions that i'm comfortable with and find a convenient way to package all of these goodies. Sean

PS... I can include both an Audioprism Quiet Line and an Enacomm AC Filter so those that are interested in such devices can see how they work.
Not so fast Brent. I have a confession to make.

While building an "adapter" to convert a female IEC plug on the end of a power cord to accept a standard AC plug for this "kit", i screwed up. After completing it, i tested it to make sure that it was working properly and found out that i had the hot and neutral reversed, effectively wiring it out of phase. The problem here is that i built it like a tank and in a manner that i could not take it back apart. My motto is "no need to take things apart when you build them right the first time". Too bad i didn't do that with this !!!

How's that for "brain surgery" ??? : ) Sean
