update

the MD is ordering new speakers with higher wattage ratings

I am so glad that I carry earplugs with me for such occasions.

[volounteerParticipant]

Well just heard from the MD.
Another speaker blew.

I guess when you crank the level up like a rock concert those old church speakers will fail.

[volounteerParticipant]

One more clue and another possibility.

Once we had this with playback from an ipad.
I thought that was fixed with new cables.

Possibly the music from the pc had been recorded elsewhere and not edited so the noise was part of the recording.
To be honest I have never had crackling noises on anything I recorded but have had other noises at times.
So unsure how to record crackling noise for playback unless I crinkle a chip/crisp bag in front of a mike like doing foley sounds.

@gerbermary

You need to do a lot more before you start to try to EQ out feedback issues.

As to the mike sizzle: that could be many things. We would need a lot more info to help.
Although it could be improper gain staging.
Did anything change before that noise started next? That would be a big clue as to the cause.

[volounteerParticipant]

Pehaps you could buy an old mac with the right software and TURN OFF ALL UPDATES to keep your mixer running !!!!!
I still have pcs with win98se and winxp to run software you cant get on later versions of win.

[volounteerParticipant]

Did you also want the PC to talk to the MPC?
I am skeptical you could get that to actually work.

Not sure you can save changes with AV login.
Try saving a new scene with the administrator password.
If that fails then submit a trouble ticket.

[volounteerParticipant]

@sahull

try saving it with a new scene name and see if your settings get lost

you are saving with the highest level administrator password arent you ?

turning off the board will not lose changes if they were properly saved with the administrator password.
I think you need to sign on as administrator then make changes then save changes to have them remembered.
saving from the a/v team sign on and recall after changing should not work as you found out.

[volounteerParticipant]

@sahull

if you make changes then you need to resave the scene to keep those changes
otherwise when you recall a scene it reverts to back to the original saved version without any tweaks made during its use

well the MD and the video guy ( a 15 yo whizkid!) have been doing a lot of work checking everything and rearranging things in the balcony for better? access by FOH operator. At least the mess is getting cleaned up and what we have inventoried.
they also redid the gain staging in the mixer. instead of one scene to be easy for operators as had been hoped for by previous MD, they will now have one scene for music and one for people talking with totally different gain setups.

While testing all the equipment cables connectors yada yada they found a number of bad cables.
replaced same. recent audio problem seem to be gone.

right now they are doing a number of enhancements to hopefully improve sound.
They added side speakers with bass earlier today ,
next they are going to mike the organ loft to feed the livestream sound,
then on to retuning piano, setting up new 4K camera for livestream, and doing other similar things.

they found a number of unused RF mikes and receivers which will be useful and they borrowed extra wired mikes from the kids group (they are getting all new gear soon) to be used with stage inputs. Who knew they were just sitting around.

It may not all be good, but they have made significant improvements in many areas.

@mikec

I mean that you can reduce all the signal about 40dB if you have the compression set to max

@tessab

sounds like you need to send in a trouble ticket to AH
they may say to take it back to the dealer

did it work okay before you posted here?
I took it as you had just bought it and trying to set it up.

Did you buy this new or was it used and you just got it from someone else who had used it.

[volounteerParticipant]

would have to check on model. but we had used it for over a year with no problem with the lapel mike in it.
the receivers are all set to keep the signal at the middle level.

I still suspect the operator did something with gain levels, or there is a bad cable/connector.

as to video my pc cannot access it to give you a link.
think they use WIX for their website and it seems to think my xp is too unworthy of seeing its web pages.

@tessab

Please verify that you have a cable from the LR out to an amplifier and it goes to the speakers and is turned on.
Ditto for Nothing is muted.
And you sent the input channels to the output LR.

Possibilities to check:
Channels are panned to center?
Faders at 0dB near the top not at bottom.
Preamp gain up enough to light center light when you test.
Nothing muted.
No compression without make up gain.
Input source is local not usb or dsnake.

Can you see the signal detected lights on the input channel strip(s)?
Signal detected bottom, then good solid signal middle light, red light top is clipping and should be avoided.

I suspect that unless the mixer is badly broken that following the block diagram and signal flow diagram
and verifying you have the path through those the same as you set on the mixer that you are likely to find the problem.

Not hearing anything on headphones if you select the input channel strip tells me that there is no signal in; or else you need to increase the gain on the screen and have the faders at 0 while you do that.
You did select the LR to monitor on headphones didn’t you? Then you might need to also push PFL button.

@NikeC

think it is shure sld but would have to go look to be sure.
they are relatively new – about 1+ years now.

but the noise was intermittent last sunday
I still suspect the volunteer du jour did some changes to the scene
and then backed them out when the noise happened

pretty sure the wireless mike is set at the one gain that we always use
and the rf receivers are never touched just the settings in the mixer if they need it louder when the orator is too low

[volounteerParticipant]

@mikec

I suspect the input level is quite possible.
The input was just changed from lapel to ear mounted wrap around mike.
