    I’m wondering what the best way for me to run an aux fed sub through my 32. I’ve talked with a number of people already, but, this being the A&H forum, thought I’d get my best and definitive answers here.

    Thanks for any help you’re willing to give!

    On my qu-16, I use mix 4 as a dedicated aux fed sub mix. I send post fader. I only send kick, bass, a little keys, and mp3 player to this mix. The crossover and eq settings for the subs are set downstream in the digital processing of the power amp for the subs.

    You could eq the dedicated mix on the mixer itself. But I don’t think there is anything approaching true crossover settings on the qu.

    There may be other methods, but I like my results. You do sacrifice one possible monitor mix, but my band doesn’t need it.

    Yeah, mix 4 is our bass monitor. I use mix 9-10 for our live streaming; would mix 7-8 work? Sorry for the novice questions, but, in some areas, I guess I am.

    Thanks for helping, Barry; I appreciate it very much!

    I would think 7-8 would work just fine. You might have to play around with panning on a stereo mix, especially if you only have one cable coming from the 7-8 outputs. But, otherwise, those mixes 1-4,5/6, 7/8, 9/10 are identical.

    I personally run the subs mono, even though I prefer stereo for mids and highs speakers.

    I usually run mono subs as well, it’s a bit of a shame that you cannot mono the stereo mix outs on the Qu (this has popped up in many discussions here), but I can usually sacrifice one side of a stereo output, and feed my subs from from a panned send. Me too, prefer a dedicated system processor, you have much more precise control over your filter slopes. Mine has three inputs, so himids go to 1-2 and subs to 3. That said, I don’t always run subs on auxes, hi-passing input channels works fine for me in many cases.

    If you have dedicated processors downstream then you could use them exclusively, and run from L&R to both.

    The QU doesn’t have crossover capable dynamics (it can be approximated as well as it can on any board, but there is nothing steep or deep enough to act as a true crossover)

    Mix sacrifice is an option, or running from alt-out if you just need a simple sum to send to an LPF fir the subs.

    Just seen that this is a 32, I run a 16 – so I don’t instantly think of the matrices, but they are an obvious place to simulate a crossover…

    Have been doing that with mix 9-10. Generally only center panned LF instruments go to subs so panning not an issue.

    I do vote for mono on stereo mixes and mono or blend control on ST1-3 inputs.
