Anyone got a diagram?
You loop the wire and then cut the bottom loop and solder all of them together.Then you solder all of top of the loop pieces together.
Virtually any length of wire that has a dielectric around it will provide some form of change, even when the dielectric is air and the nearest form of plastic molding. This is a subtle format and as with other subtle formats changes are made with every thing you do.The Ground Control devices are a fairly high Q application of this discovery, done to get the physical size down to something reasonable and the installation hassles to a minimum. They are tuned to be useful across the widest range of ground side conditions and even so, we have to have two different ones to cover the two main needs.The Standard covers those situations where the dearth of back wave coherence, the signal being pulled from the ground beyond the load, has caused the perceived illusion of sound stage to fall between the speakers and be fairly shallow. The Reference uses subtly different techniques to enhance the depth of information coherence in the back wave, with a corresponding reduction in stage width.Interestingly, these two characteristics cannot be gotten out of the same device, but can be gotten from stacking two devices, one Standard and one Reference.At this high a Q, small mistakes in materials can cause rather large changes in performance, Without an understanding of the basic principles of operation, and they are not derivable from first order approximations of LCR characteristics, any alterations made, in manufacturing techniques or materials, will be uncontrolled and the results will be unpredictable. And then there is the question of repeatable characteristics across the products manufacturing lifetime.There are actually good reasons why we charge what we charge We build what we build in the way we build it, to provide the widest range of possible after load conditions with a useful retention of back wave information coherence. We are well aware that some situations cannot be solved by one or the other types of Ground Control we provide, that is why we have a 30 day unconditional money back guarantee.I will point out that I can tune our devices to solve even those difficult cases, just from feedback from the end user, I do not have to hear the system in question.And again, please, do yourself a favor and keep these devices away from digital circuit grounds. The digital device will loose clock sync and if the ground does not properly reset, with a complete power recycle, the device may never work properly again. Even a buffer resistor ir capacitor is enough to protect the digital portion of a CD player or out board DAC so keeping the Ground Controls on analog RCA outputs will not harm a mixed mode device.Bud
All you do is loop and stic the two ends in the -?
Mitsuman, assuming that the bold type portion is what you are asking after.Think of an audio system. The primary focus of all effort to date has been upon the leading edge, sustain and decay of audio signals. The part that travels directly from source to load. If we assume that information theory is correct, then this "signal" is a coherent, structured format. Careful attention is paid to keeping this "signal" chain from source to load as a proper data packet, in information terminology.Electrical engineering has done a stunningly good job of performing this task.Now, let's consider what happens to this positive going signal, this coherent data structure, once it has made it's positive going pass through the load. Where does it go? What form of controls have been brought into play to maintain the coherence of this information packet ,up to the moment that their is an E Field moment, during which time the vector of the signal changes and this data packet is pulled back through the load, as the back half of the wave form that was so carefully controlled during it's positive going portion.Certainly a fully differential circuit answers this question. Equally certainly, a single ended circuit with a poured ground plane mirroring the signal components also performs a good portion of what the fully differential circuit provides. What manner of control is there for the much more typical single ended, with respect to ground circuit used in most commercial electronics. There are many good reasons why you do not want a poured ground plane and you will find that most competent audio designers are aware of them. A fully differential circuit is not cost effective and so, is not marketed as a common solution to a problem this is easily ignored. Strip grounds on a PCB are much more cost effective but the signal that has passed through the load is not being held here. Rather it is being dumped into the power system ground plane and out to earth ground, or as a circulating current in the chassis or even just left to ring in the strip ground, zero signal reference. None of these common solutions can maintain the signal integrity of the back half of the wave form.This is what Ground Control is designed to do, to provide a partial alternative that provides a local support for maintaining the signal coherence of these neglected portions of our source material. Live sound does not have this problem of information de-coherence and if you read the comments of those who have corrected this situation with Ground Control you will discover that they speak directly to this coherence issue. Most of us don't have any experience with obtaining fully coherent back wave from our audio systems and when presented with a corrected signal make comments like, more natural, a greater "ease", more rounded, with the illusion of 3 dimensions being more pronounced.The information retained is that which is most easily lost, wide band low level, image structural information. Reflections, internal note and transient colors etc., but only those from the back half of the wave form, after the load.Bud
Bud Can you post a link to purchase yours?
I would think that product advertising would belong in the Industry Ads Jason,,, not the Lab Circle. Cheers,Robin
So this information is sent to the speakers from the amp, but is "lost" due to the crossovers, voice coils, drivers, internal wiring, etc. not being able to produce it. It is then "found" by installing a wire pigtail into the "-" terminals on the speaker, adding this "lost" information that didn't get captured the first time around, so it can then be heard?
