DIY Monitor Controller?

    I was looking into a few things. Is it possible to just use an Dual Ganged Audio Taper in between my DAW output and my active monitors. I am currently using a Behringer crap mixer to adjust control room monitoring levels and I hate the sound it gives my speakers. I was thinking about making a little box with inputs, outputs, and then wiring the Pot properly to just get a passive stereo attenuation knob. Would this actually work at all? Or am I just wasting my thoughts on this one?

    2 words- stepped attenuator.

    Ganged pots will not give you the accuracy between the left and right sides. If one pot is slightly different than the other. A switch with hand selected resistors will work better.

    These are within .5dB

    You can always adjust your monitors internal trims after.

    Does anybody know where to get stepped audio attenuators for a decent price then? I really didn't think that the cost was going to be as high as i have seen around after looking. :eek:

    I'm at least adequate at electronics and soldering, if not much better. Ive made all my own snakes, cables, some decent condenser mics and other things as well. I'm open to any suggestions and ideas. I actually welcome diy projects, and not only to save money. They are usually fun and help one self to learn more about things rather than just buying it.

    Cool, ok so get some 0.1% surface mount resistors, or at least 1%. I would grab a meter and match them by hand. Resitors like:
    http://www.panasonic.com/industrial/components/pdf/AOA0000CE14.pdf

    Grab a Switch Like:
    http://rocky.digikey.com/WebLib/ElectroSwitch/Web Data/C4 Series.pdf

    You want a switch that does both left and right at the same time So you a double pole (DP). You need a few postions maybe 12, so thats a DP12T


    For values check out this site:

    PM if you need more info- But this should get you thinking.

    go to groupdiy and do a search
    but here is an example of many threads
    http://www.prodigy-pro.com/forum/viewtopic.php?t=14474&postdays=0&postorder=asc&highlight=mikkel+monitor&start=0

    JLM Audio for the HAL
    http://jlmaudio.com/user/viewtopic.php?t=3
    uses the Texas PGA2320

    Mikkel has some ideas
    http://electronics.dantimax.dk/Kits/index.html
    looks like he has moved
    ??
    I'll see if I can find the new place
    ??
    this could be it
    http://stiftsbogtrykkeriet.dk/~mcs/
    ?
    I can't make either of these work at the moment
    perhaps a server issue


    ESP may help with ideas
    http://sound.westhost.com/projects-9.htm

    the Factory has a couple of ideas but I've been so slack so they are no where near adequate yet
    http://www.diyfactory.com/projects/dawmonswitch/dawmonswitch_3.htm
    I haven't written up the MK2 project withthe VCAs
    MK1 is just as per the GoldPoint or DACT sort of thing
