Yes, a very simple and intuitive tool to wind the coils. But did you see all the wires concentrated in the middle leaving you no space for the secondary windings to run. Do we have some kind of bearing support to make for the wire wheels to run on, so that, the layers can be neatly adjusted as coils on the bobbin?

That's true, I found once starting the first round to get the wire bobbin as far as you can, the angle to the new coil it's getting larger and the wire just put one after another by it self, also a kind of break to have a tension in the wire it's necessary.

Great! What is it that determines the quality of the microphone?
@viocaia
@viocaia 14 күн бұрын
Let's start with the capsule itself. For a dynamic microphone like Shure SM58 (most of the rockers are using it on stages) the membrane have to be light and flexible, so a better response to both ends of the audio spectrum, low and highs. For condenser and electret microphones (like bulky studio mics or the one in your mobile phone), they are already pretty linear and good range, so in SX9 I'm sure the electret capsule it's pretty ok. In my situation, the megaphonic and flanger sound of this set it's because analog to digital converter. For saving costs I'm sure it's the most basic and cheapest possible! I believe the sampling rate it's max 22KHz, but for CD quality needs at least 44KHz. Also there is signal to noise ratio which have to be as low as possible (-in db). Overall for the money it's useful though. So there are a lot of factors to determine a good quality microphone, but I should start with a good capsule of course, the first in the chain.

I have a MicroSolar 600 watt inverter that idles at a measured 350 milliamps. This is 4.5 watts at 12.8 volts. The big Victrons idle at 11-15 watts. Low idle power is possible, consumers need to prioritize this feature to encourage manufacturers to optimize it instead of making the cheapest product. Powering small appliances directly from DC is generally more efficient than using AC overall. Using smaller inverters generally helps but not all small inverters are low in idle power. Fancy power saving modes generally don't work well for many appliances as the power is essentially going on and off and interfering with their monitoring and control electronics.

When measuring it with the voltmeter, my power supply shows 21 to 24 V instead of what you mention of 17 or 18V. The XLR inputs on the audio console stopped working. Is it possible that my power supply is bad? and has that made the entries no longer work? Everything else is perfect, even the 1/4 inputs and the console works very well. Thanks for your help.

It's normal to show more than 21V AC, the voltage goes down after rectifier to DC and regulators. 48V for XLT+R it's supplied by a internal circuit, I don't have the schematic. BUt look for a capacitor like 1000uf at 75 or more V, that should be related to phantom and check the parts around.
