AWG is short for American Wire Gauge, a standardised system of measuring the cross-sectional area of Cayin Tube Amp. This is used to determine 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 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 about 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. Go ahead and take area (pi x radius squared) to get the cross-sectional area, and appear the AWG chart (example below) to work out AWG. When a cable has multiple strands, a similar operation is done to work the cross-sectional section of each strand, which can be then simply just multiplied by the quantity of strands to have the total AWG. However be careful when comparing this figure as AWG is not linear. For each and every extra 3 AWG, it is actually half the cross-sectional area. So 9 AWG is approximately one half of 6 AWG, which is half again of three AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
So 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 means less power loss. For applications to home theatre, this is actually true approximately a degree. A principle is the fact for smaller speakers, a cable of approximately 17 AWG is enough, whereas for larger speakers anything as much as 12 AWG or even more will provide you with great outcomes.
The reason some cables of the 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 from the Speaker Cable to help 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 make certain you don’t compare them by sight.
Another factor why two same AWG cables may look different in thickness is just how the internal strands are created. Some cables have thinner strands, while others have thicker strands. Depending on the size and placement of those strands, cables can be made to check thinner or thicker compared to what they are.
Is AWG a great indicator of quality? In a nutshell, no. A sizable AWG (small cable) may easily be too small for the application (for example, you shouldn’t be employing a 24 AWG cable to run your front speakers). However, AWG is actually a measure of quantity, not quality. You ought to make sure that all of your speaker cables are of at least Line Magnetic 518ia.
Does AWG matter? How so? AWG certainly matters. You need to be sure that the cable you are using is plenty to handle the energy you’re likely to put through them. Additionally, if you are performing a longer run, then even more thickness will be required. However, many people get caught up excessive in AWG and end up forgetting the reality that when a sufficient thickness is reached, additional factors enter into play. This then becomes more a matter for “audiophile” features to settle, including using better quality materials such gaqgbw silver conductors or improved design.
Wire gauge is unquestionably a good fundamental indicator of methods sufficient a cable is made for the application. However, it is actually in no way a judgement on quality, or perhaps a specification to look at exclusively. As being a general guideline, after about 11-12 AWG, thickness becomes much a smaller factor, whereas for most hi-fi applications 18-19 AWG would be the minimum cables to make use of.
