    hope that help Gadget give thanks if u need more let me know
    also Gadget on my 480 input 1 & 2 is the HI MId HI and the Low Mid for out puts 1 2 3 4 5 6 and the input 3 & 4 is Lows for out put 7 & 8 long time ago some on on your site sent me the link for that to work like that I down loaded it to the 480
    the speakers do push out, the system use to sound perfect until a friend of mines change all the settings in crossover and eq and compressor, now the highs are to lound and dont sound the same mid is muddy, and subs playing with a mid hard sound, when it was set up i guess around 8 years ago when i purchase the 480 it was set up with pc, and now i cant set the settings do to no usb port on laptops no more. so if u can give the basic settings for a 4 way system for a horn, and mid hi, and mid low, and a basic setting for subs any horn loaded will get me in right direction, i been playing with settings and not as good as it sounds, also that 480 drive rack was the best sounding system in town, lot of people purchase that unit from hearing it on my sound Gadget, so if u can give me basic crossover settings for a four way system hi mid hi mid low sub, give thanks Gadget
    yes its a dj set up Gadget, yes that woofer works very good in scoop cabinets, they shake down the building to the drop cieling fall lol, those scoops and the 480 drive rack is a monster chest pounding bass, thats why am trying to get the right crossover and eq settings back, so if u can give me the basic crossover settings for a 4way system and basic eq settings for parametric for each 4 channels will help very much Gadget, give thanks

    I told him I am buried.. and EQ and Peq settings sight unseen... I don't think so, basic crossover settings... maybe, but these are proprietary cabs and it doesn't look like the appropriate driver for the cab were used...

    So, I am bushed, and interested in your thoughts...

    Yeah I got some PMs too.

    There is a whole lotta info here that I can't even follow up on so I am going to pull some numbers out of my butt. Some experimentation will be necessary. Let's start with:

    SUBS 40Hz BW18 - 100Hz LR24
    LO MID 100Hz LR24 - 250Hz LR24
    HI MID 250Hz LR24 - 1.2KHz LR24
    HIGH 1.2KHz LR24 - OUT

    On the high/hi mid xo point maybe experiment between 1 KHz and 1.3 KHz. Set all DriveRack outputs to unity. Zero out all EQ filters. Disable all limiters. Listen to some of the music you typically play through the system and report back with what is missing and/or what is excessive.

    Gadget, feel free to jump in and disagree.

    Dennis, Those numbers look fine.. IF, I had the time right now I might have proposed the same ( or VERY close :mrgreen:) things.. (like minds and all)

    You have to understand that tuning a 2 way speaker is dicey... you can do a lot more damage if you don't know what your doing than just letting the passive crossover take care of the crossover...your trying to go 4 way and that has so many potential cans of worms that I can't even begin to tell you.. Dennis can. because he works with SMAART... but to tune a totally passive 4 way system... and get it right ... without the tools... your chances of getting it right are slim... unless you have some serious chops tuning systems without tools or years and years of experience.

    This is REALLY difficult...

    Gotta get some sleep... :|

    I am not sure I understand what more you want? Dennis gave you all the settings we can really do sight unseen. Try those and see what happens.
    Gadget and Dennis
