control Stereo Volume

I have an old style Cassette SONY x-plod car audio stereo player for car. i have removed main cassette section & replaced it with an USB MP3/FM board with remote control. I made this because i believe in SONY's amplifier so successfully tracked amp track to get source from USB board. But here i got a problem with board which forgets volume level & restores to 25 level(Default range 0 to 50 level). so volume is boosting at high at every start of player. Now i want to Analog stereo volume controller between USB board's output & SONY amplifier's input. so what should be the configuration for volume controller??? Output target for amplifier is 4speaker(2x150Watts[Front] & 2x180Watts[Rear]). Does my idea works?? if it works what is the configuration for Analog stereo volume controller.??

Vintage Potentiometer to digital Potentiometer problems

I have modify a vintage wooded radio into a digital amp with bluetooth. It work great, but since I wanted to have the outside look I had no choices but to hack the 20k potentiometer on the digital amp (lepi 30$) to use the original Potentiometer.. the vintage one. I'm looking to find a way I can fix this Potentiometer so it would reach the 20k. The Potentiometer on the Lepi circuit board is a b20k for sure, but I don't know about the vintage one, there no info written on it. it's 2 questions for one thing, fix this volume so it won't blowout the speakers.   1- how to fix this ? I believe a resistor should do the job, but 'how much resistance needed? 2- if this is a resistor, well how do I solder it ? (6 wires, which one?) Any help would be greatly appreciated!

Program or script to change volume...? Answered

Another question that is way out of my league (woe is me).  I need (or rather want) a program, in either Java or VBs (if there's a better one like Python or something, that would be alright too) to change the volume of a Windows computer.  It would also be a good showcase of your skills to make it able to change the volume of a specific program or application.  The way I intend to use it is as if it were a function, rather than a program. So a different script will activate it (perhaps by writing it, which in Java I don't think is possible) and then set the volume and the program to change the volume of. If that can't be achieved, could it be made to read a text file (or something else) with two lines on it; the first the program, the second the volume. If the first line says something like none, It would change the volume of the whole computer. Hopefully I've given you a good enough description to make it clear exactly what to do. Thank you in advance.

Speaker (single) Volume Control

I have a Panasonic home theatre system, standard set up. ( 2 front, 2 rear,1 centre and 1 Sub woofer). Unfortunately, because of the room layout, I'm not able to site any of the speakers in an ideal location. So, I have to make do with the best poss. One of the rear speakers is close to where I sit, the other 3mtrs diagonally opposite. I want to insert some form of volume control into the feed of the adjacent speaker. So that when set the rear speaker volume level there is a better balance between the near and distant speaker. I am unable to access any other wiring or components apart from the speaker feed wire, so it has to be something in line. I tried a dimmer switch (dont laugh) but that attenuated the signal too much, and was barely audible. The speaker is 6 ohm imp and 60wat power input. Any suggestions appreciated, apart from buying a new house!

device to read volume level in a room

I was just thinking that something like this might be handy for a teacher. If you had some device that could read the volume level in the classroom and display it in a bar format so the students know when they are getting too loud. It'd be nice to be able to say, "ok, you can talk with your group but stay under volume 5" or "if you keep it below volume 3, you'll get more marbles". Anyone know if this could be done and how?

Can anyone explain it so that I (not a mathematician) can understand it?

URGENT! Question about in-line audio control between amp and speakers? Answered

I have a unique project that I am almost finished with, but need to make one last adjustment to. I am running a 3.7W Class D Audio Amplifier. The amp has two outputs. I need one to run as designed (controlled by my iphone before the signal gets to the amp which will be set to almost max volume). I need to then control the other output channel to reduce the volume. Any suggestions? It seems like I might be able to just get an inline control out of an old set of earphones, but I am not entirely sure. I always assumed (and pardon my ignorance if this was a foolish assumption) that the buttons in my iphone earbuds actually signal the phone to change the volume, and isn't really "in-line". So, I don't think those would work. Would an old set from Goodwill work for this? I have seen posts where others are asking similar questions and the answer seems to be a 1K Ohm Pot (which are apparently really tough to find). Since I have a 3.7W amp, perhaps a 10K Ohm Pot will work (people have said this doesn't work well for their headphones).  To summarize: 1) Will adjusting one output channel on a two-channel amp work? (or will the increased resistance simply close off the channel and pump all the signal to the other channel?) 2) If this will work, can I use a 10K Pot? 3) If not, will an old-school in-line volume control from some headphones work? Sorry for all the info...trying to be thorough! Thanks a ton for any advice!

box(es) for sub(s)?? How many? What size? Here's some measurements.

So... Got some subs I had lying around: http://www.crutchfield.com/p_500SWE1042/Alpine-SWE-1042.html?tp=111&tab;=features_and_specs I am trying to figure out if I should vent (I don't think I should from research) and if I can do them in a single box or if it's better to put them each in a box. I also haven't found out if I should JUST double the volume for having both in one box or if it should be a different amount. The suggested volume I've calculated is 4.1 cu ft (but that seems a bit huge).       V(as) 33 liters   |    Q(ts) 0.66    |    10 Inch The speakers will be in series, I don't know if this affects whether or not I can put them in a single box. How much does the shape of the box matter? Can I make a rectangular cube and put the speakers at either end or do they need to be on the same side? When it comes to fill would it be better to use something fluffy that takes up a large amount of space like very fluffed out cotton or is carpet always the better way to go? I cannot find how much fill I SHOULD use. I have found suggestions for just carpet on the back wall and some for all sides wherever you can and even two people suggested to fill it to about 80% (though it did not say what with). Any questions?
