AWG is short for American Wire Gauge, a standardised system of measuring the cross-sectional area of Cayin A88t Mk2. This is utilized to determine how much current a wire can handle. AWG causes much confusion for consumers, as the standard can be a little hard to understand. Is 12 AWG much better than 14 AWG or the other way around? The reason 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 regarding how AWG is actually calculated.
How is AWG calculated? If a cable had been a solid circular wire, then AWG is rather straightforward to calculate. Take the area (pi x radius squared) to have the cross-sectional area, and look in the AWG chart (example below) to work out AWG. In case a cable has multiple strands, a comparable operation is performed to work out the cross-sectional part of each strand, which is then simply just multiplied by the number of strands to have the total AWG. However be careful when comparing this figure as AWG will not be linear. For each and every extra 3 AWG, it really is 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.
How does AWG affect electrical properties? You would’ve noticed right now 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 certainly true up to an extent. A guideline is that for smaller speakers, a cable of around 17 AWG is plenty, whereas for larger speakers anything as much as 12 AWG or more will provide 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 internal conductors. Therefore, a cable manufacturer could easily increase the thickness from the Speaker Cable to make the cable appear thicker. This isn’t necessarily bad, as as much as a point increased jacket thickness reduces other unwanted properties. Just make certain you don’t do a comparison by sight.
The other factor why two same AWG cables may look different in thickness is the way the internal strands are made. Some cables have thinner strands, while some have thicker strands. Depending on the size and placement of such strands, cables can be made to appear thinner or thicker compared to what they are.
Is AWG a great indicator of quality? In a nutshell, no. A big AWG (small cable) may easily be too small for the application (for instance, you shouldn’t be utilizing a 24 AWG cable to perform your front speakers). However, AWG is a way of measuring quantity, not quality. You should make certain that your speaker cables are of at the very least Line Magnetic 218ia.
Does AWG matter? How so? AWG certainly matters. You need to be sure that the cable you are using is plenty to handle the power you’re likely to put through them. Additionally, if you are doing a longer run, then even more thickness would be required. However, some individuals get caught up excessive in AWG and end up forgetting the fact that when a sufficient thickness is reached, other elements enter into play. This then becomes more a matter for “audiophile” features to resolve, including using high quality materials such gaqgbw silver conductors or improved design.
Wire gauge is certainly a great fundamental indicator of how sufficient a cable is made for your application. However, it is actually by no means a judgement on quality, or a specification to check out exclusively. As a general guideline, after about 11-12 AWG, thickness becomes much a lesser factor, whereas for most hi-fi applications 18-19 AWG would be the minimum cables to utilize.
