Low signal from mic to computer - Phonic NEW PHONIC SONIC STATION 22 MIXER wDFX +TALKBACK MIC

Where are you getting the low output? It would be very strange if all channels failed in the same way so it is probably something common to them all. Can you get the clip light to illuminate at all by turning the gain up on a mic channel and shouting into the mic? You are referring to the gain at the top of the strip not the slider aren't you? What happens if you assign a channel to the other sub channel, does the level come up through that? What happens if you take the output from the aux send and you send signal there, is it the same issue?
I may be completely wrong but I suspect if it is only mics that are causing a problem you may have the routing set up wrong or not set a level somewhere else right.

Ground the 3rd pin! :)

If you are using the fx/send port to the mic-in port (I have no idea why you would want to do that) but nevertheless, check the red fx dial and make sure it is at 12 oclock and turn the pan dial to 12 oclock also. remember if you are using mic input 1 or 2 with a mic that requires Phantom power the button needs to be locked in the down position. OK im assuming you have checked and set your gain and volume levels on the 802 prior to plugging in your mic. If not do so now.(unplug all outputs and with mic plugged in speak into the mic while turning up gain until you get distortion which is indicated by a rewd light next to the "pan" button...once you see that light turn the gain dial back slightly and you should be set) have volume at 12 oclock on both l"evel1" and "main mix: dials. Now goto your windows desktop and right click on your volume control "speaker" icon. Click on "Playback device" you should see your mic in the list on enabled devices.If you dont see your mic in list right click the screen and click show disabled devices. Enable your device. If it is already enabled right click it and make sure it is not muted. finally go back to list of playback devices and right click your mic and click "configure speakers" run through the tests. close everything.mic should be working now. If it is not I suggest you plug your mic into either the line in from the fx/send or keep it in the mic-in port and plug the other end into the head phones port.Or better yet, get an rca to mini stereo jack and use the cd/tape out jacks to send your signal to the mic port of your computer......keep playing with it...you'll figure it out.There are so many different ways to hook up your perephrials its mind numbing sometimes.

Make sure you are driving LINE LEVEL signals to this and not mic level signals.

Have you PFL'd the signal from the mic to see what level you're getting? You mentioned phantom on....are you actually using a condenser mic? What model mic is it? Are you using XLR or phone plug? EQ set flat? Do you have another mic/cable to try? Anything else plugged into the board has strong signal?

If the mic is a low Z- mic, that might be the issue. Check the mic straight into the sound card of the mac and see if it works or if it is shorted. Is there a switchon the mic? it may be dirty.

You need to check the actual signal levels to make sure they are within the specs for the unit. The mic input is low impedance. Your mic should be like a Shure SM58 or equivalent. The output is fairly high... up to +14DB which will require you to turn down the trims on a mixer this runs into or set a -20Db pad at the input. I suspect your distortion is from the device output to the mixer input. It is VERY important that the mic does NOT "hear" the speakers as the feedback loop resulting will be mass distortion. The guitar should also not "hear" the mains.

Make sure you turn the Phantom power on the Mbox2 on as the Shure 87A requires it being a condenser mic.Make sure you use XLR mic cables. These are just things to check on.

You mention "mic"... to do stereo you need two mics...

If you are trying to "PAN" a single mic, then you should use a WYE cable and have the single mic go to both input channels.

You can run to mic connectors but will probably have to turn down the trims. DO NOT run the drum machine at too low a volume as the signal to noise ratio will suffer. Best to attenuate at the mixer.
ALL interconnected equipment should be powered from the same source or receptacle to avoid ground loops.
