    Hello everyone.
    My name is Peter I’m a newbie.
    I am looking for some help, I have a CQ18T which I run our 6 piece band though.
    To save leads running everywhere I purchase a custome made Stage box with 8 inputs and 4 returns
    The inputs are male extra to match the mixer and the returns are TRS for our fold backs.
    At rehearsal we just used 5 vocal inputs all plug into the stage box after about an hour each microphone failed. Not all at once but over the next 15 minutes.
    On testing all inputs and outputs I found that there were no connectivity issues with the fan of connections or the box inputs.
    The place where I had it made mentioned that it could be and issue with the mixer as all connections passed testing.
    I’m hoping someone else has had a similar issue.
    I’m not confident to use the stage box in a live situation until this is sorted. As you can appreciate a 6 piece band with 5 vocalist and 5 instruments, 3 fold backs a sub woofer and front of house there are lead’s everywhere
    Hope for a solution
    Regards
    Peter

    A stage box should be passive. Does the mixer work OK with the mics connected directly?

    Hi thanks for quick reply,
    Yes the stage box is passive, and yes all the mics where plugged straight into the mixer after it failed and worked fine.

    In that case, your problem lies 100% within the stage box itself. You need to check the quality of the solder connections on every connector in the stage box. It sure sounds like the quality of that box isn’t very good.

    Thanks Brian,
    I believe exactly what you are saying, the “Manufacturer” is saying what happened is not possible as you are also saying it’s and extension of each individual lead.
    I will be taking this up further and request some “restitution”
    Regards

    To be honest, I can’t imagine that it’s your passive stage box.
    During your rehearsal, you probably hardly moved the box or the connections.
    Nevertheless, after an hour (!), all the inputs you were using failed one after the other.
    If I understand correctly, you checked the box afterwards or had it checked.
    Everything was probably moved during that time, but no problem was found.
    So I’d be much more inclined to believe that it was an electronic problem.
    Once in my life I’ve experienced the phantom power in a mixer slowly disappearing.
    All the condenser microphones stopped working – also one after the other.
    This may not be the case for you, but in my opinion, a tested (!) pure cable extensions shouldn’t be able to cause this kind of error.

    Strange indeed. Do you recall if signal was still coming in right after the “fail” ?

    In answer to the above,
    Mic’s are all Shure SM58’s
    Auto gain is not used
    Unit tested ok without errors.
    What electronic failure could cause this issue? Yet the mixer has performed perfectly in all other instances as recent as Saturday night 🤷🏼‍♂️
    I do have an analogue mixer which doesn’t have as many inputs so would use for vocals only that I may try and see it the same occurs
    Otherwise I’m at a loss.
    I do have rehearsal tonight so I will test it again
    Regards
    Peter
