CSI/SPECO SPC-30RT Weatherproof PA Speaker with 75/25v Transformer

did you know that in over 90% of the cases when you use an electrical device you always use a transformer they all have different shapes and sizes but what they mostly do in your device is stepping down a high sine voltage like your mains voltage into a smaller sine voltage this way your device can create a stable DC voltage by rectifying it aside from this awesome function it also creates some loss during the transformation which might be a bit too much to explain right now but there's one unwanted effect which you can clearly hear when there's a big load attached or even a short-circuit in my case it is called 50 Hertz hum and it is referral to the frequency of our mains voltage now the question is do other frequencies work as well or even music so in this video I will find out whether such a transformer can be used just like a speaker let's get started I started off with this e and I
