    Wonder if this is possible.

    If I have an input into Channel 1 and have the HPF and PEQ set, is there any way to get the same CH1 signal without the HPF and PEG settings available to send to a ‘Mix’ channel….I won’t say why I want to do this though!

    Yep.

    See page 40:

    “Choose the global Channel Source for the selected
    mix. This is the point in the channel signal path that
    feeds the mix. This affects all sends to the mix.

    Choose Post-Preamp if you want the sources to
    the mix not affected by any channel processing.”

    I will often use the “Pre-EQ” setting for monitor sends. I still want the HPF in there.

    Ah, great!

    So just to clarify, if I choose Post-Preamp then it will send the signal without any HPF settings (as well as without any PEG settings)

    I’m actually trying to cobble together an Aux send for a sub.

    Also, when you say “refer to page 40”, what document do you mean?

    I have only found this for the QU=App so am I missing something.

    Note that this is a global setting. Why not feed the sub from a proper crossover with the amps?

    Hi,

    The system is a pair of active RCF TT25A ii and single JBL VRX918SP.

    I know the system is ‘undersubed’ so to speak but it’s for pub rock in small/medium sized rooms (100 people). I rely a good bit on the natural kick drum and bass backline and don’t run very bass heavy mix.

    The RCF’s have an inbuilt 100Hz HPF.

    The Sub has either 80Hz or 120Hz LPF. I want to run the sub at 80Hz and get the RCF’s down more into that range by not using the onboard HPF and using the QU-SB HPF settings on each relevant input. I’m basically only using the sub to take some of the load off the tops to maintain a bit of headroom (the RCF tops go very hard if required).

    I know the QU-SB isn’t a loudspeaker processor though…just trying things out…

    Alternatively, I could just use the Audio Out on the VRX918SP as the HPF at 80Hz but I’d like to try playing around with the HPF on the QU-SB.

    Also means it’s one less level of processing that the signal feeding the tops has to go through.

    Hmm – you could also double up on key channels if you have the fader count…

    Tell me more pls…not really following what you mean there?

    What Bob’s suggesting, is that you patch, for example Kick to both channel 1 & 2 (with an analogue splitter at the desk, or digitally if you’re using the dSnake), allowing you to eq each one differently. Would give you more options but eats up extra channels.

    OK, got it now.
    I think I’ve got enough control using the Post-Preamp setting you pointed out earlier.
