AWG means American Wire Gauge, a standardised system of measuring the cross-sectional area of Cayin 300B. This is used to see how much current a wire can handle. AWG causes much confusion for consumers, as the standard can be a little challenging to understand. Is 12 AWG a lot better than 14 AWG or the other way round? Why one cable looks thicker than another even though they have identical AWG? Is AWG an excellent indicator of quality? Does AWG matter, and if so, how? These are all good questions, and we’ll get to them shortly. Firstly, let’s briefly touch on how AWG is actually calculated.
How is AWG calculated? If a cable had been a solid circular wire, then AWG is fairly straightforward to calculate. Take the area (pi x radius squared) to get the cross-sectional area, and look the AWG chart (example below) to work out AWG. When a cable has multiple strands, a comparable operation is carried out to work out the cross-sectional area of each strand, that is then simply just multiplied by the quantity of strands to get the total AWG. However be mindful when comparing this figure as AWG is not really linear. For each and every extra 3 AWG, it is half the cross-sectional area. So 9 AWG is about 50 % of 6 AWG, which is half again of three AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
How exactly does AWG affect electrical properties? You would’ve noticed by now the smaller the AWG, the larger the cable. Larger cables could have less DC resistance, which means less power loss. For applications to home theatre, this is certainly true as much as a degree. A rule of thumb is the fact that for smaller speakers, a cable of around 17 AWG is sufficient, whereas for larger speakers anything as much as 12 AWG or maybe more provides you with great outcomes.
How come some cables of the identical AWG look different in thickness? Two factors dominate here. Firstly, the AWG only takes into consideration the interior conductors. Therefore, a cable manufacturer could easily raise the thickness from the CopperColour Cable to make the cable appear thicker. This isn’t necessarily a bad thing, as as much as a point increased jacket thickness reduces other unwanted properties. Just ensure that you don’t do a comparison by sight.
One other factor why two same AWG cables may look different in thickness is just how the internal strands are designed. Some cables have thinner strands, while others have thicker strands. Depending on the size and placement of such strands, cables can be produced to look thinner or thicker compared to what they are.
Is AWG a great indicator of quality? In a nutshell, no. A large AWG (small cable) may certainly be too small for a particular application (for instance, you shouldn’t be utilizing a 24 AWG cable to operate your front speakers). However, AWG is actually a way of measuring quantity, not quality. You need to make sure that your speaker cables are of at the very least Line Magnetic 219ia.
Does AWG matter? How so? AWG certainly matters. You need to be sure that the cable you might be using is enough to handle the energy you’re going to put through them. Additionally, should you be performing a longer run, then even more thickness will be required. However, many people get caught up a lot of in AWG and forget the reality that after a sufficient thickness is reached, other factors enter into play. This then becomes more a matter for “audiophile” features to solve, like using high quality materials such gaqgbw silver conductors or improved design.
Wire gauge is undoubtedly an excellent fundamental indicator of how sufficient a cable is perfect for the application. However, it really is by no means a judgement on quality, or perhaps a specification to look at exclusively. As a general guideline, after about 11-12 AWG, thickness becomes much a smaller factor, whereas for many hi-fi applications 18-19 AWG would be the minimum cables to utilize.
