Anyone who still remembers my article "Disadvantages of onboard sound – influence of graphics card, headphone sensitivity and motherboard layout" will of course also wonder how I measure all this and what technology is behind it. Since we have no secrets and the response was also very large, Frank Schmidt ("Bigreval" in the forum) and I thought about how we can get the gene for upcoming tests (sound cards, motherboards) even more comfortable.
And if you leave an engineer off a leash and two older gentlemen agree that you should give your monkey so much sugar until he falls dead (dear animal friends: of course only literally seen), then such a black box comes out as we put it on it the image below. Well, for the Red Dot Award, the design isn't really hip enough, but expediency goes before bling bling.
And why install sleek mechanical switches when the mind and the electronics have something against it? The good piece is reliably resilient up to 11 watts per channel, which is easy enough. Concrete resistors really have something permanent. And to get it right, they are connected and selected in parallel until the value really fits.
In the following video I will also explain to you what the whole thing looks like when it is switched on and what exactly happens when you put on a signal and want to measure the result. Of course, some things have been simplified again and have not been discussed down to the depths, but for general understanding it should be enough. I'm still working on video making, but it's getting slow. And the rest is understandable anyway.
However, a project is still missing when it came to the power consumption of the individual motherboard components or Rails goes. But we are still building on this and when everything is in place, there will be the necessary transparency action and the first tests. Because running synthetic benchmarks is actually a bit lame. Dealing with the specs, on the other hand, is much more exciting. And that is exactly where we want to start in the future, because nothing is more boring than a copy of a copy.
