AWG means American Wire Gauge, a standardised system of measuring the cross-sectional area of Cayin 300B. This is utilized to see how much current a wire can handle. AWG causes much confusion for consumers, as the standard can be a little difficult to understand. Is 12 AWG better than 14 AWG or the other way round? How come one cable looks thicker than another even though they have identical AWG? Is AWG a good 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 regarding how AWG is actually calculated.
How is AWG calculated? If a cable was actually a solid circular wire, then AWG is rather straightforward to calculate. Go ahead and take area (pi x radius squared) to obtain the cross-sectional area, and look the AWG chart (example below) to work out AWG. If a cable has multiple strands, a comparable operation is done to work out the cross-sectional part of each strand, which is then simply just multiplied by the number of strands to obtain the total AWG. However be mindful when comparing this figure as AWG will not be linear. For each and every extra 3 AWG, it is actually half the cross-sectional area. So 9 AWG is all about half of 6 AWG, which can be half again of 3 AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
How exactly does AWG affect electrical properties? You would’ve noticed right now that the smaller the AWG, the larger the cable. Larger cables will have less DC resistance, which results in less power loss. For applications to home theatre, this is actually true up to a level. A guideline is the fact that for smaller speakers, a cable of approximately 17 AWG is enough, whereas for larger speakers anything approximately 12 AWG or even more will provide you with great outcomes.
How come some cables the exact same AWG look different in thickness? Two factors dominate here. Firstly, the AWG only takes into consideration the inner conductors. Therefore, a cable manufacturer could easily increase the thickness of the Audiophile Cables to help make the cable appear thicker. This isn’t necessarily bad, as up to a point increased jacket thickness reduces other unwanted properties. Just make certain you don’t compare them by sight.
The other factor why two same AWG cables may look different in thickness is how the internal strands are designed. Some cables have thinner strands, and some have thicker strands. Depending on the size and placement of those strands, cables can be made to appear thinner or thicker compared to they are.
Is AWG a good indicator of quality? In a nutshell, no. A large AWG (small cable) may definitely be not big enough for the application (for example, you shouldn’t be using a 24 AWG cable to run your front speakers). However, AWG is a way of measuring quantity, not quality. You ought to make certain that your speaker cables are of a minimum of Line Magnetic 219ia.
Does AWG matter? How so? AWG certainly matters. You need to ensure that the cable you happen to be using is enough to handle the power you’re planning to put through them. Additionally, in case you are carrying out a longer run, then even more thickness could be required. However, many people get trapped a lot of in AWG and then forget the reality that when a sufficient thickness is reached, additional factors enter in to play. This then gets to be more a matter for “audiophile” features to resolve, like using higher quality materials such gaqgbw silver conductors or improved design.
Wire gauge is certainly an excellent fundamental indicator of methods sufficient a cable is for the application. However, it is by no means a judgement on quality, or perhaps a specification to look at exclusively. As being a general principle, after about 11-12 AWG, thickness becomes much a lesser factor, whereas for many hi-fi applications 18-19 AWG would be the minimum cables to make use of.
