I recently used my New QU-24 for Mixing a Live Band.After all checks, when the vocalist came for check, they wanted some FX and I added the channel to 4 different effects (FX1-FX4) and suddenly there was feedback. I had to mute the Effects to stop the Feedback.I tried turning it back ON again 1 at time and as soon as i had FX3 on i had the same issue.
Further investigating, I saw the following.
With FX1 Selected and the Layer showing levels on the FX Returns. All the 4 Effects had “Return” at “0” Position for FX1. Same was FX2,3,4.
So i tried the following, with FX1 selected, I had the FX1-Return at “0” and FX2-FX4 Off. Basically for every effect, I only had its own FX return set , all others off.
And It worked. I did the entire show and had no issues.
Question: Is the condition i am describing seem possible?. If so, do we need a “Self” Protection in the QU Software, which does not allow someone to set the faders in a loop condition or atleast have some kind of loop detection.
Apologies, If my long post does not make sense.As i don’t have a better way of describing it.
Hello Viikan,
I had the same problem during a soundcheck of a bigband.
After some experiments I found that the FX were also returned into groups 1 & 2. I don’t know whether this setting is by default or by an erronuous set-up during an earlier gig.
The groupoutputs are/were routed into the master, which caused the same problems as you mentioned.

Thank you for your response. I will have to power on the mixer tonight and see if the default setting has it correct.
But, As an “InBuilt” protection, shouldn’t the Mixer software prevent this from happening. I mean allowing the FX Return faders to be moved when in the FX Mode. I feel, it would be a good feature to have, as this could happen by error to anyone.
