Just purcahsed the Driverack PX as I am putting together a PA. The sales guy told me this would work but the instructions do not say how to connect my setup. I have 2 Yamaha S115IV cabinets that I am going to power with with a QSC 2450 and 1 JBL PRX 518S power subwoofer as speakers. The mixer is a Behringer 16 channel unpowered. How do I connect this setup? Will this model Driverack work?? Help!

    Welcome...
    Will this model Driverack work?? Help!
    Certainly.
    It makes little difference if the speakers are powered inside.. or outside. The limitations are stereo 2 way or stereo 4 way (tops and subs) or you can easily forget about the right channel all together and have a mono 2 way system...The PX has the same xover types as the DRPA it is just limited by the number of outputs..and no delay.

    So, if you want stereo outputs.. select a 2x3 setup. This will get you a stereo tops, mono sub (left mono out...)
    I am setting up a similar rig right now... with Anchor Extreme powered tops and a pair of passive subs run mono through an external amp. (backwards from what you have but still...)

    Mixer out to L/R PX ins...hi L/R PX outs to the hi amp ins...
    Left Low (mono) out to powered sub.
    Now, I want you to go to the "READ ME FIRST BEFORE POSTING" section...and the FAQ section:
    viewtopic.php?f=61&t=959
    viewforum.php?f=60
    and learn how this whole thing ties together. Were willing to help but you need to learn how to use this equipment. It WILL be your friend but you need to get your learn on.The PX will do most of the work but YOU need to be able to tell it what you want.

    Were here ... almost always...

    I read your links and it's coming together. I am going to run mono because the amp is actually a QSC 1450 and would not have enough power to run the yamahas in stereo, so I'm going to run the amp in bridge mode. At least until I get a more powerful amp for the yamaha's. Over 500W per channel. Thanks a bunch!

    Ok, that's fine, set the unit up for 2x3 and use only the left hi output (the auto EQ does the left speaker first in a dual mono setup... but it really doesn't matter here, but the left mono out is used so you might as well stay symmetrical) You won't believe how much better the Yamaha's will sound after proper setup and auto eq...

    Try this:
    subs
    HPF out/ or 20hz LR12 effectively letting the sub limit it's own HPF
    LPF (the highest point we want the subs to go) 118hz LR24
    Yamaha's
    HPF 118hz LR24
    This will put the subs from 37-118hz, and the tops from 118hz up
    read the Auto Eq posts in the FAQ section before attempting the Auto Eq

    I'll try that... Something just occurred to me to ask... I also have a Yamaha Ex2000 powered mixer. Could the PX be used with that mixer when using only the 2 yamaha cabs for a small room setup (gig)? Thanks for all your help. There is so much knowledge to be gained here!

    Does that mixer have a "Line out & "Power amp in" patch point (or something sounding the same)?

    Yes it has ST 1 L R Out, ST 2 L R out, plus P.Amp In R L... It says Bridge nxt to Left jack.

    No, that mixer does not have what you need... you could use an external amp.. but the internal one does not have a patch point.

    What it would need is a pair of jacks that say 'mixer out', and a pair that says 'amplifier in'...
