AWG stands for 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 a lot better than 14 AWG or vice versa? The reason one cable looks thicker than another even though they have identical AWG? Is AWG a great 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? When a cable was a solid circular wire, then AWG is rather straightforward to calculate. Consider the area (pi x radius squared) to have the cross-sectional area, and appear the AWG chart (example below) to work out AWG. If a cable has multiple strands, a similar operation is done to work the cross-sectional part of each strand, that is then simply just multiplied by the number of strands to have the total AWG. However be careful when comparing this figure as AWG is not linear. For each extra 3 AWG, it really is half the cross-sectional area. So 9 AWG is all about one half of 6 AWG, that is half again of 3 AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
So how exactly does AWG affect electrical properties? You would’ve noticed by now that the smaller the AWG, the larger the cable. Larger cables may have less DC resistance, which means less power loss. For applications to home theatre, this is really true as much as an extent. A rule of thumb is the fact that for smaller speakers, a cable of about 17 AWG is sufficient, whereas for larger speakers anything as much as 12 AWG or maybe more will give you good results.
The reason some cables the exact same AWG look different in thickness? Two factors dominate here. Firstly, the AWG only takes under consideration the interior conductors. Therefore, a cable manufacturer could easily boost the thickness of the XLR Cable to create the cable appear thicker. This isn’t necessarily bad, as up to and including point increased jacket thickness reduces other unwanted properties. Just make certain you don’t compare them by sight.
Another factor why two same AWG cables may look different in thickness is how the internal strands are designed. Some cables have thinner strands, while some have thicker strands. Depending on the size and placement of those strands, cables can be produced to look thinner or thicker than they are.
Is AWG a good indicator of quality? In a nutshell, no. A sizable AWG (small cable) may definitely be too small for the application (for example, you shouldn’t be employing a 24 AWG cable to perform your front speakers). However, AWG is actually a way of measuring quantity, not quality. You ought to make certain that all your speaker cables are of a minimum of Line Magnetic 219ia.
Does AWG matter? How so? AWG certainly matters. You should ensure that the cable you happen to be using is sufficient to handle the energy you’re likely to put through them. Additionally, if you are carrying out a longer run, then even more thickness will be required. However, many people get caught up a lot of in AWG and forget the truth that when a sufficient thickness is reached, other factors enter in to play. This then gets to be more a matter for “audiophile” features to settle, 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 is by no means a judgement on quality, or even a specification to check out exclusively. As a general guideline, after about 11-12 AWG, thickness becomes much a smaller factor, whereas for most hi-fi applications 18-19 AWG is the minimum cables to make use of.
