    Hello!

    I have question.

    I will be using 2x passive satelites + 2x passive subwoofers, with 2 amps and no external crossover. How do I split signal with Qu-16 (Highpass / lowpass), and how would I make Mono out (for subwoofers) to be controlled with same master fader as LR?

    Or what other options are there with this setup?

    Thanks!

    Unfortunately, the simple answer is that you can’t do either or these things. As far as As far as I know, none of the lower cost digital desks have crossover functions yet, though I’m sure that is a feature that will be included in the future.

    It is tending to become a built in feature in some amps these days, and does not seem to add an enormous amount to their cost.

    As I assume you will already have amps though, I would look for a simple crossover or speaker management unit that performs both these tasks, and mount it with the amps. That means you can use your speaker system with other sources, not just your QU, which is bound to be useful at times.

    Yesterday I worked with x32 and it has some really nice Routing options. High pass stereo out at 100 Hz, and Low pass Sub mono out at 100 Hz (using Matrix) and route them to the same LR fader – not same as crossover, but useful. Can we expect High/Low pass on mixes in future on Qu-16?:)

    You’ve said it: That’s not a crossover. You likely won’t get a flat system response with such a setup and I expect some phase issues as well. There’s another thread on this with various plots showing the issues.

    I’ve done it with other systems, it’s not recommended.

    Yup. Basically going to mess up your sound. Get a real cross-over. Even an inexpensive used analog unit for $25.00 is going to be better than the HPF/LPF found in your “all-in-one” digital mixers.

    Thank you for help!

    I know some guys doing things like that with X32. I guess they are wrong. Thankfully I have found Behringer crossover in garage, it should do the job.

    One more question. I have bass guitar and it is used for 2 different types of music in one night. Is it possible to plug it in channel 1, but have processing on ch 1 AND 2, so I can have different processing for the same instrument, to use it separately? Or just get a splitter cable?

    They are not wrong because they are not using HPF/LPF: they are using the buit-in crossover function which allows the user to choose any of the 3common filter types and up to a 24dB/octave slope. Qu does not offer this.

    And yes, go with a hard-wired XLR split to feed the bass to two channels for separate processing. Or set up the two and save them both as user pre-sets. That way you don’t burn a channel and can still switch between the two settings with a button push or two.

    If you have a stagebox then the bass can be patched to two channels, or you could use scenes to change he settings…

    +1 on the stagebox, but I wouldn’t do a scene change for one instrument. Too much chance of changing more than you want and a bit more work to set up than an A/B pair of presets. K.I.S.S.

    …there are still user libraries which may recall a whole channel setup with few button presses. So if there is some time to switch sounds, that may work (still using a single channel).
