I am a newbie to using audio recording mixer and sound boards. I just purchased a Numark iCDMix2 DJ machine. My church has a Allen & Heath GL2400 sound board. I want to connect the RCA cables to the GL2400 board? But I am not sure how to do this. Can you advice me? I have not found an books or tutorials for newies to learn audio hooks and wiring. The back of the NuMark has labels showing Master and Zone Left and Right on the Output label.
Thank you
Howard WIlson

If you pull the knobs off, you will find lock nuts under them. You could tighten them up. See if the knobs have set screws on them to lock them in place before pulling them off. On Allen & Heath, I don't think they do but, just in case.
If one of the channels on your Allen & Heath XONE:42 mixer is not functioning properly, it is likely due to a problem with the channel's internal components or electronics. To repair a blown left channel, you will need to disassemble the mixer and locate the source of the problem.
Here are the general steps you can follow to troubleshoot and repair a blown channel on your Allen & Heath XONE:42 mixer:
Disconnect the mixer from any power sources and remove any cables or accessories that are connected to it.
Carefully disassemble the mixer, following the instructions in the user manual or a service manual if available.
Once you have access to the internal components of the mixer, carefully inspect the left channel for any visible damage or problems.
If you find any damaged or faulty components, you will need to replace them. You may be able to find replacement parts online or through a specialist DJ equipment retailer.
If you are not comfortable with disassembling and repairing the mixer yourself, you may want to consider taking it to a professional repair service. A technician will be able to diagnose the problem and repair the mixer for you.
Keep in mind that repairing electronic equipment can be complex and requires specialized knowledge and tools. If you are not familiar with electronics repair, it is recommended to seek the assistance of a professional.
Carbon track on fader 1 is open because of wear or just broken, if you are getting sound then the ground carbon track is out but certainly the problem lies in the pot.
I will ask a question: Did you remember to power ALL inteconnected equipment from the SAME and I do meanALL and SAME receptacle or power conditioner module? If you powered your stuff from several receptacles in a large venue, likely ground system bounce has caused damage. I don't know what you mean by "dont get any signal in."... explain that... There are tests to run to isolate the problem but if you got hit with ground bounce transients you could have major damage. That is a big board for an outside venue so you might describe what you had configured from mics, etc. to speakers. ALL professionals know to run power back from where their amps are to the mixer alongside the snake. I will give you points for carrying a spare... ALWAYS a good plan as electronics DO fail and of course at the worst time.
Is this for live sound? You can use your aux outputs as sends if you're not using them for monitors and return to spare channels. If any units are being used for only one channel, either run them in-line (use the effect unit's wet/dry settings) or use the channel's direct out and return to a spare channel.
If one effect is applied to several channels you could put those into a sub group, take that sub output to the unit and return the 100% wet mix to a spare channel.
Be careful not to send the return channels back to any auxiliaries you're using for effects.
There can be any number of reasons for this problem - solve it diagnostically by starting with something that you know is working and work through systematically to the other end.
Test a microphone on a separate amp to make sure it works okay. Check amp and speakers working. Check that all output cables from mixer to amp are working by testing separately.
Plug microphone into a channel on mixer. Also plug in headphones and turn headphone volume control up.
Make sure input sensitivity knob is turned up a bit (say half way) and main output faders (yellow) are up.
Check that channel is turned on (little button just above the channel fader- needs to be pressed down)
press pfl (pre-fade listen) button (next to button to switch channel on)- do you get any sound on main output or headphones or any indicator lights on mixer to show signal is getting that far (eitehr the individual channel metering lights or the main ones in the central section)?
turn off pfl - make sure channel fader (slider) is up - normal position is ) - about 3/4 of way up. Check lights again on individual channel and main output section - any signs?
Is the sub mix button for the channel pressed down - in which case you will need to bring sub mix (red) output faders up as well as main faders.
If you have got signs of signal on the individual channel but not main see if the channel has been routed somewhere odd (like a subgroup of channels).
Plug a working amp and speakers into one of the auxiliary outputs and use the relevant auxiliary send knob (on each channel just above the faders and pfl switches) to pan some signal to that auxiliary out - do you get anything? There is also a headphone socket for listening to the auxiliary channels (with a selector switch /knob to determine which one - make sure it is in the right position) try listening to the auxiliary output with headphones - anything? If yes the problem lies in the main output section.
Check that there is not a jack plug in the insert socket (to route signal through an external effects unit) without a matching return jack being plugged in - if appropriate is relevant effects unit switched on and correctly set up - if unsure remove the insert plug to take it out of the system.
Make sure any mute buttons are not switched in on main outputs.
Hey tifly415, did you ever fix this problem? My church has the same mixer and last night it did the same thing twice during a congregational meeting. No fan noise, but the meters all peg and we get this horrible descending squeal which gets louder as you pull the faders back in a moment of sheer terror and panic. Power it off and back on and it's ok for a while then it happens again. It's happened to me a few times during rehearsals in the past and it definitely is not mic feedback because no one was near the console or doing anything at the time. It seems to be totally random and unpredictable.
I, too, suspect a power supply problem, but it never seems to happen when my troubleshooting gear is nearby. The only thing unusual yesterday was that the mixer was left on almost all day, so it may have been warmer than usual.
Anyone else have the same problem, or better yet, know of a solution?
