    Just a quick one, if doing this from step one, if you eq a single sub separate (ie you only have a single sub) and then with a single side (l or r) don’t forget to drop the sub by 6db and then if you play the two sides together add back the 6db for the sub... reason being in theory at least the two sides will sub by 6db so you will find your sub is 6db light if you don’t do this

    Question: Why did you chose to use a midrange and a tweeter for the center channel? Did you find just using a midrange was not enough?

    No, it was mostly because a) I could, since the Helix Ultra allows for it and makes it easy, and
    b) I imagined it might make it easier to pursue a 2 seat tune

    I've since scrapped the idea of a 2 seat tune, but having the 2-way center channel has made my overall tune sound great.

    Perhaps I have no idea how to properly use virtual channels. I have

    FR L tweet, FR L midrange, and FR L midbass tied to Virtual Channel A
    FR R tweet, FR R midrange, and FR R midbass tied to Virtual Channel B
    Center midrange on Virtual channel E (primarily to activate real center)
    Rear fill on Virtual channel F (input 50% L, 50% -R)
    Sub on Virtual channel K?

    How do I auto EQ this whole setup in virtual channels? Link them all together like outputs? I'm unclear of the advantage to doing this.

    If you have a newer DSP with their Advanced Co-processor (ACO) functions then virtual channels can be activated through the DCM menu tab.

    This is a way to link channels together and mess with them without affecting the tuning you did in the OUTPUTS section. This is also where you can activate their new gimmick effects like stage ex-pander and bass effects. So far I find it somewhat useful but extremely limited.

    The virtual channels feature is not available on all ACO-based DSP's. It's not available on the mini or the DSP.3. Only on the Helix Ultra and I think one of the newest DSP+Amp combo devices.

    So you cannot use virtual channels on the DSP Mini (even though it's an ACO-based DSP).

    However, the "FX" options *are* available on ALL of the ACO-based DSPs. So you *can* use features like Augmented Bass Processing, Real Center, etc on the DSP Mini.

    Hope that clears things up.
