Mike C, all I can figure out … as I can’t get any FX returned to LR on any mix with those faders down as illustrated in the photos, is that the ‘FX Sends’ are going prefader to L-R and the Mixes.

Is this what you’ve been trying to explain to me?

And if so, then all I need do select Fx1 and FX2 respectively and change the Fader Send on the Upper Level to pre on those channels?

Regardless, it still seems a 6 of one, half-dozen of another proposition as all functions perfectly as I’ve outlined in the steps above.

Actually I see a draw back to setting up pre fade because any time I wanted to use one of the Mixes for FX3 or FX4 I’d have to be careful to go back and reset the pre fade to post fade … whereas with all post fade I’d never worry about that feedback loop.

But, please … elucidate me.

I’ve come to the suspicion that the QU-Pad and QU-16 layers must be different … there is no way I get any FX output with settings like the QU-Pad photo above.

What I said earlier is correct. The upper layer includes 9 Master faders for FX1 to Mix 9-10, the FX ‘Sends’ functioning as master faders for the FX.

To avoid feedback loop you only have to avoid bringing up the FX Returns in a bespoke FX, i.e., the FX1 Return when FX1 Upper Layer is selected, or in other Mix assigned to FX3 or FX4. As you select the FX, different Mixes or LF in the upper layer, those faders never move as you go from one selection to another.

And to hear your FX anywhere else you must have the FX returns up on the selected Mix or LR.

I’ve gotten a lot of help here and from other forums … so I’m going to try to give back something for the next ‘Rookie’ that comes along: step by step FX setup. This will take one mic input channel and send it to LR and one Mix with selected FX. For ease of discussion I will refer to UL (Upper Layer) and LL (Lower Level) fader banks.

The only thing I won’t cover is the Pre Fade and Assign buttons, as by default they are properly set to Post Fade and Assigned to all masters by default. You probably haven’t touched them and shouldn’t unless you have some specific need.

1. Hit your FX square button to the right of the LED screen under the ‘Home’ button. On the top of the display in five small squares you see FX1-FX4 and ‘Back panel.’

2. Select the small FX1 square in the display. Use either the default FX type that appears or do the following to change the type. The function key will let you chose an FX Type and matching library of presets. Choose one.

3. When the FX type’s graphic appears and while with ‘FX1’ still selected hit the ‘Back panel’ button on upper right of display.

4. On the left you will see a pane with a downward arrow centered. The text can display either ‘Unassigned,’ Insert, Mix>Return or Ch>Return. Select Mix>Return. (FWIW Ch>Return is like an insert in which FX engine can only be used on one channel but FX level can be controlled by another fader).

5. In the center of this display is a middle pane with title Input and another drop down menu. Select FX1. This is also on the QU-16 where you would assign FX3 and FX4 to one of the mixes.

6. Without changing your display, now hit the FX1 physical button on the lower right side of the mixer just to the right of the master fader.

7. Select LL with FX1 selected. Raise your fader on your connected mic input and give a ‘check, check.’ You will see that in the display the tiny meter on the right side of the ‘FX1’ shows activity. Your input channel is now connected to your chosen FX.

8. With UL selected while FX1 is still selected raise the ‘FX1 Send’ fader to unity. (Actually, as this is in effect a master fader, you can raise or lower ‘FX1 Send’ in any selected mix or the LR … but let’s get it ready!) MAKE SURE ‘FX1 Ret’ fader is all the way down when FX1 is selected to avoid a feedback loop!

9. For purposes of example, I will use Mix 4 as a monitor feed where I want the signal and FX delivered. The exact same procedure would apply to LR Main or any mix. Select Mix 4 and raise the Master Fader or the ‘Mix4 Master’ … same result as they are locked to one another while ‘Mix4’ is selected.

10. With LL selected while Mix 4 selected raise channel fader of your connected mic.

11. With UL selected while Mix 4 selected raise ‘FX1 Ret’ to taste. You will now have your FX. You should also note on the UL that you will have signal activity on both ‘FX1 Ret’ and ‘FX1 Send.’

I’m sure most here won’t need this … but ‘Rookies’ do come along.

Mike … can you break this down a little more specifically, please? I’m not quite getting it.

I do understand about the looping back of the fx … but this confuses me: “fx send tab.” By this do you mean the FX1 and FX2 buttons on the right of the master fader?

And this: “That will make it harder to accidentally turn up an FX send fader on a FX return and loop it back into itself.” I got rid of the feedback by doing the opposite. For example, I selected the FX1 button and then I turned down the FX1 Ret and raised the FX1 Send?

And finally: Just to clarify … in case I have this all backwards and you straighten me out. I don’t understand the Assign function. I note that in the same scenario as above with the FX1 selected by the Master Fader, on the upper layer when I push the assign button the left side (ST1 to FX4) lights up except for FX1 and the right side (FX1 Send to MIX 9-10) remains dark. If I then select FX2, I get the the same result, except now that now FX1 Ret lights up and FX2 Ret goes dark.

Thanks for any help.

Hi …

I’d like to add one little thing to this wonderful thread, in case another ‘Rookie’ like myself searches it out in hope of figuring out QU 16 FX patching.

I did everything as instructed above (thanks especially to Cornelius!).

The FX was coming through including using Mix 1 and Mix 2 for FX3 and FX4, respectively … but I was getting these horrible feedback loops when I turned up the send faders.

I may be the only one ignorant of this, but lets say for example you want to patch all FX into Mix 4. Once you select Mix 4 you need to bring up all four Return faders (FX1 Ret, FX2 Ret, FX3 Ret & FX4 Ret) and Send faders (FX1, FX2, Mix1 & Mix2) … but!!!

When you select any of the FX, e.g., FX1, from the panel do not bring up the Return faders or you will get feedback.

FWIW when you cycle though your FX, i.e, FX1, FX2, Mix1 & Mix2 in my example, with the top layer selected you should see exactly the same things: those fades up where you set them along with the fader of the mix you are monitoring.

Hope this helps someone … it was painful to figure out!

Thank you both! … Curious that they don’t display Channel Library under the Processing>Channel Tab instead of the Processing>PEQ Tab … but I guess there was no room with the FN>Select Source screen.

@ Dick Rees and the ‘pitch pipe:’ Thank you! Thank you! Thank you!

I am just a retired guy who started hosting karaoke at several local venues. I’ve Googled over and over and yours is the first cogent lifting of the feedback veil for the ignorati. Much appreciated … and my singers will thank you too!
