Hi, does anybody know how sensitive are these little components (solid state relay)? I was thinking about if they can be triggered just by the small energy that a led vumeter circuit uses to turn on a regular led. I want to replace the leds for solid state relays instead, so I can switch much...
Hi, I have this doubt, what happen if I dont use the third pin of the potentiometer in an audio application? Its just a pin connected to ground, is it really necessary connecting it there? I need to do some potentiometer extensions, and if I can only use 2 pins, then I will use a minor number of...
I did it with a desoldering pump, but I did a dirty and difficult job, somebody told me to put an excess of solder that covers all pins, so now with all the pins hot at the time, all I need is to pull the piece and remove it once the solder is still very hot, I hope I knew this before doing...
Hi, few minutes ago, I tried to desolder a potentiometer of a double layer circuit board, I found that some pins are soldered in the surface, and I can not access that area because the potentiometer body are hidden them. So I only could use a copper mesh to remove the solder of the pins in one...
As you can see here, I am taking this very seriously, will put some leds around the woofer, in the front, which will be commanded by the comparator connected to one the of the loudspeaker terminals, so there I avoid what you mentioned can happen, but I am still thinking about what Audioguru...
Thanks betwixt, then I think I am simply going to connect it to one of the loudspeakers, which I believe that stereo sound, its not bridged. is not it? TPA3116
You did not only remove that coupling capacitor, but only modified a resistor and pot value, reason? Also, is there a danger having that pot on a max or min ohm value setting? I supposed this is for gain, right? So I should start at max ohm value and adjusting the best setting for it.
Thanks.
Coming back to the simple vumeter comparator (LM311), so I should not connected to the amplifier output which is bridged (btl), unless I am using a separated power supply? Or should I connected to one of the loud speaker? this is something I did not understand at all. Some electronic parts have...
I see, take a look at this:
https://www.parts-express.com/dayton-audio-sd215a-88-8-dvc-subwoofer--295-484
This is 80w, and 31hz response, I needed something like this at first instance then, I was ignoring that factor since the beginning, price its similar to those cheap car audio subs.
I have been comparing the specs of few 8" drivers on an enclosure calculator (I am understanding many things now), I found that there is not big difference in final enclosure hz with another brands with similar or a bit more price, like pyramid, pioneer, planet audio, I still have to try the...
Thanks for the data, then this is good scenario to try the polyfill fiber and see what can it do. As I mentioned before, can I have read some users talking about it, and they said that it really made impressive improves lowering the frequency. This is going to be good experiment, I always...
Well, I know that it won't be a stereo sound in all sense, but I think I am helping a little by doing this, imagine the waves that each loudspeaker spreads on its own angle, filling a room, it can be more notorious when getting some distance from enclosure, and even close, aside, anyway putting...
Guys, I am moving soon, and wont complicate too much with the enclosure for now, so I think that the dedicated bass chamber of my enclosure, it's going to be sealed, 1 cubit feet for 8" driver, and filled it with one pound of poly-fill. Have you heard the miracles can do with sealed enclosures...
Well, Helmholtz-Resonator calculator told me that can down A LOT the hz, to set the enclosure around 25 hz if I use that 3" pipe, 24" long, and keep the enclosure size about one cubic foot, I would put a little more space, about 1.5 3F, the thing is that, yeah, that pipe is very long. Do you...
