- Stereo speaker level input to line level mono output converter
I am trying to connect an amplifier with 100W RMS per channel output to a subwoofer that only has a single channel line level input The amplifier does not have a volume controlled line preamp outp
- power electronics - How do buck regulator modules with integrated . . .
Looks like most of the volume of the converter is the inductor They need a certain volume of ferrite and more space for the copper winding to meet specifications (saturation current, inductance and DCR, for example) Usually the cost is much, much lower if you can afford the space If cost is of no concern you can use whatever you like

- power electronics - Flyback transformer size vs. core losses . . .
Because the geometry (shape) is kept, so are all the proportions, the magnetic path length will increase x4 and the magnetic material cross-section will increase x16, i e all lengths increase by the same amount and the resultant volume increases x64 The inductance factor will increase x4:
- How could I build a headphone stereo to mono converter?
I'd like to build him a compact stereo to mono converter Ideally, it would have an input 3 5mm stereo jack and an output jack that delivers the converted mono sound I've tried the simple circuit below using two jacks where I connected the channels using resistors, however, his devices detect the short circuit and won't play the sound
- How to reduce audio noise from Bluetooth module
For this particular BT MP3 module, when using USB the noise is very low and almost inaudible at mid to high volume (The amp has it's own volume control), but when using BlueTooth the noise is so loud that it renders the whole thing unbearable
- How bad of an idea is it to use an AC transformer for a DC-DC converter?
However, the term fly-back transformer is also commonly used Because the coupled inductor in a flyback converter is designed to store energy, it often has either an physical "air" gap in the core (which is actually often filled with a solid material to reduce stresses and vibrations) or a "distributed air gap"
- batteries - Using capacitors as a battery back-up - Electrical . . .
You need a switching power converter to discharge as deeply as possible until diminishing returns set in According to this answer, you'd want to use capacitors rated for 400-450V, since per unit volume they give you most energy stored You'll want to charge them up to 95% of the rated operating voltage, and discharge them down to 50-100V
