Hi Scott,
Thanks for asking, I have been extremely occupied and I just came up for
air. I have a financial services provider customer delivering new
business each year of more than a billion dollars of life insurance
activated online for more than two years now through my proprietary
application. I just wanted to carve out a few percent of their paper
based business, but the system has been so stable and friendly that most
of the new business fled by itself to my online application. I hope to
take the product to other insurance providers over the next few years.
I would love to know what each of us is doing, where you are going and
the unique successes we have had. You never know, we may be able to
shorten our delivery cycles by sharing our skills and subject matter
expertise, and as a side effect not worry about dinner bills! There is a
lot of talent on this list.
Your computer soundboard should have at least one external AUX IN, my
cheapo self built box has two. There is also a CD input on the
motherboard that is meant to be used for audio connection to the DVD
drive/ CD drive that many times is left free. That should give you
anywhere from one to three inputs into your computer that you can adjust
independently and listen to all simultaneously. Why don't you assign one
(older) computer to be your mixer and plug them all in there? The
computer you are working with also has an AUX OUT, that you can pipe to
the mixer computer. If you want more lines, there may be an add-on board
that you can stick into your (older) mixer computer, or buy a new audio
mixer computer board with full blown professional features, and
graphical controls on the monitor. To get really excited about the
project, you could get an inexpensive small (POS type) touch screen
monitor for direct adjustments! The $3000 price tag on an archaic,
obsolete, dust prone, scratchy, carbon slider mixer that the trade rags
want to sell you is criminal in this age of technology. I just can't
stand by and let some one get heisted. :) Hope the ideas are useful. But
please don't apologize if they don't work for you. This is fun!
If you don't find anything satisfactory, let me know, I will be happy to
mount the components in a battery box and send it to you, my compliments.
I am redoing my 9 year old bathroom and it is a lot of work. I can
imagine what your hundred year old home wants. Send us some pictures.
Before and After!

driven to express myself adequately :)

Hi Sri,
I don't think we've heard from you for a while. Keeping busy?
This will allow you to listen to all the channels
simultaneously (cacophony in my opinion, but hey, I am not the one
listening!)
It's not so much that I want to listen to multiple streams of music at once, it's more that I want to hear the various sound prompts from the computers whenever they happen, audio from videos like YouTube, and the background sound therapy I have on (special white-noise at low volume) while listening to music (I don't always use the same machine for playing music or video, and I have more desktop than laptops these days).
I can do it now, but it means 3 sets of speakers crowding my desk, and then
physically unplugging and plugging cables if I want to tune in my short-wave
radio onto a decent set of speakers, and stuff like that.
Thank you for the detailed description of how to build all this. I used to love
doing this stuff when I was kid - but I honestly don't know if I would ever
have the time or patience to build this now (aside from work, I'm also
renovating a 100 year old house), so I respectfully express my gratitude Sri,
but decline your generous offer.
There must be something ready made from somebody that does something this simple? 4 or
more small audio input jacks, with some measure of volume control for each, to produce
one "mixed" level of audio output to one set of speakers.
I appreciate your reply, and sorry if I haven't been more clear on what I was
looking for. Thanks.
Scott,

I used to do a lot of electronics a long time ago. Here is a simple way
to do what you want to do:
Buy some 4.7 Kilo Ohm resistors (say 10) by mail order. Solder one end
of 5 resistors together and hook this common point to input of the left
channel in you amplifier.
Do the same for the right channel. Now each free end of the resistors
becomes an independent input for any source you choose. Take left and
right channel pairs and hook them up to shiny gold plated RCA
connectors, and mount the connectors on the terminal box. You can build
this passive mixer for a few bucks. Purists consider this type of mixers
the best because not being active (no transistors) they don't contribute
distortion. It does cut the max volume down a bit, but when did you ever
play full blast? If you are picky, reduce the resistor to 1K Ohm.
Of course you also need a ground line (or return path for each channel
(for each source from each connector)). If you are working with only a
few sources the wiring doesn't get too complicated.
You control the master volume from the main amplifier. You control the
individual sources from the volume control of the sources themselves (if
you use speaker or headset outputs of the sources). So you have all the
flexibility. This will allow you to listen to all the channels
simultaneously (cacophony in my opinion, but hey, I am not the one
listening!), just like the volume controls on your computer based mixer
with CD, AUX, MIC, MIDI and PCM inputs.
If you are seriously interested and verbal description is not working,
express your displeasure and I will make a drawing.
Have fun.

Hi Robert,
Thank you for your time on the search. I think what I need is something more
like
this unit:
http://www.radioshack.com/product/index.jsp?parentPage=search&summary=summary&cp=&productId=2104026&accessories=accessories&kw=audio+mixer&techSpecs=techSpecs¤tTab=summary&custRatings=custRatings&sr=1&features=features&origkw=audio+mixer&support=support&tab=techSpecs
Where all the inputs are active at the same time, not just a single one switched
on. I'd have to get line adapters and a mess of cables though - I guess I was
just hoping for something that was "ready made" for the small stereo jacks and
impedance rating that computers and small devices like the iPod output.
I miss Radio Shack. They were my favorite store when I was kid, but they left
Canada a few years ago. Unfortunately the online Radio shack doesn't ship to
Canada directly. The chain that replaced them him is sub-par and don't carry all
the same stuff.
Oh well, I appreciate the effort, I'll keep searching. Thank you.
Scott,
