It was several years ago that we began our journey into the amazing world of music and sound engineering. The conditions were far from ideal since we had to work inside a relatively small studio suite, with very old and low-quality recording devices that many times were blurring the outcome of our work. But our enthusiasm was such and we were so excited by this process because we felt we had the possibility to contribute a few more pages to the endless book of music history. However, apart from being excited, I distinctly remember being frustrated with the final copy’s sound quality. On some occasions, there were colorations in the mid-band, while on other occasions there was an irritating lack of detail and to make matters worse on many other instances there were annoying distortions that were produced by the old and limited-capabilities equipment.


After a few years had passed, our studio suites were modernized with some of the finest and most expensive equipment available at that time. However, the strangest thing was that some of these irritating distortions continued to make their presence felt. It was the fact that led us to conduct several audition tests with various combinations between the devices and the peripherals of our studio, aiming at an effective solution. Having done that, we saw a notable improvement in sound quality and an instant disappearance of all audible distortions after the use of high quality cables with the proper specifications. That is what motivated us in 2005 and led us to the formation of a company specializing in the manufacturing of high quality cables for the demanding sound engineers and producers. The results were satisfactory and the demand for these products exceeded our initial expectations.


The true challenge for us lay in the fact that we needed to gain the confidence of the demanding audiophile, even though we knew that we had to invest a lot for a market of a much smaller size. However, factors such as the ongoing pursuit of perfection, our love for music and our great passion for high end audio, led us in 2007 to establish Signal Projects.


Signal Projects is a company whose only intention is to manufacture superior quality cables that will assist audio and video devices to simulate the original event with higher accuracy and bring the listener one step closer to that. Our cables, with their sophisticated design, the effective insulation, the efficient mixture of high purity metals, the implementation of advanced shielding techniques and their superior construction, will help signals to travel with the lowest possible interference and become ideal connections for any reproduction device within any price range.


Many believe that the manufacturing of audio cable is not an intricate process, basing their opinion on the simplicity of the product itself. In addition to that, the reality where anyone can take a simple wire, a set of plugs and a solder to make any type of cable, is undoubtedly a fact that reinforces their opinion.
But if we want to be honest with ourselves, we have to admit that such cable applications, will never be able to provide the qualitative specifications required by modern audio and video devices. And if we consider those cases where some serious amounts of money have been invested on reproduction equipment, by people who want to refine the performance of their systems, aiming to bring themselves closer to the original event, then it would be totally unwise to rely on simplistic cable applications.

For those cases, we believe that cable making becomes a lot more demanding as a process, due to the large number of parameters that have to be considered and controlled in order to maximize the performance of reproduction devices. Factors like resistance, capacitance, impedance, inductance, skin effect, power loss, proximity effect, propagation delay and many others, need to be always measured and controlled during the manufacturing of high end audio cables, and in Signal Projects… we leave nothing to chance.


Besides the importance of shielding techniques, grounding configurations…


The optimum insulation material would be one with absolutely no response to an electric field…


Since the early days of radio communications, all engineers and circuit designers…


In cable making, the term “ground” refers to the physical ending of the shield…
