What is the best way to run the mic on desktop


Your condensor mic requires special electrical handling usually reserved for proffesional audio equipment, not a PC. You will need two pieces of equipment, a short XLR cable and an adapter cable.
1) Behringer PS400 Ultra-Compact Phantom Power Supply.
This will supply the mic with necessary Phantom Power.
2) Rapco Horizon ISOBLOX Transformer Isolation 1:1 BLOX Device
This will isolate the Phantom Power from your computer, allowing it to work as necessary.
The adaptor connector cable you need will be a female XLR (with pins 1 and 3 shorted, pin 2 hot), through a cable connect to a 1/8" mini plug. They connect in that order with a short XLR cable between 1) and 2). .

I have a Eupoport EPA 900 system. Recently I started getting a consistent, low pitch and fairly loud hum out of both speakers. The hum adjusts with the volume, and I have tested it with various working...


Is the hum there with NO input cables connected? If not, you have bad cabling. Make sure you use only XLR to XLR mic cables and not the junky ones with a 1/4 inch plug that are for Karaoke machines. These devices usually use switching power supplies and do not have the power supply originating hum of older equipment. If the volume control adjusts the hum, then the hum originates previous to the control which is either in the preamps or the external inputs.

Have an A&H 32 chan , gl2400. when testing with the mic, i get a loud hum when boosting the master very up. Not happening with line source.


Make sure your mic cables are XLR to XLR and not cheesy Karaoke type cables with 1/4 inch mon plugs on the end. Please note that I have found some mic cables with wiring errors. They had the shield and one of the signal lines reversed. please verify that your XLR mic cables are wired with:
Go to thiis site and verify your cables:

Please note the pin numbers as they may not be what you expect. Ground is actually the shield or braid and the red and black are twisted pair signal lines.

Brand new ag30 when I plug my mic sm58 into it all I get is static no sound as in singing comes through it I'm using a XLR to quarter brand new lead.. Have tried everything when I hit the tip of mic sound...


You should be using XLR to XLR cable, NOT a 1/4 inch cable. There is a problem of the 1/4 inch being the unbalanced version and is not compatible with this unit's input.

Use the XLR to XLR mic cable and it will work fine.

The cable you have would work for one of those cheap Karaoke machines...

How do you use the mixer with a regular combo amp and stereo mic cable?


This is not hard to do, but it will require some adapters. Hosa company makes adapters to accomplish this. For example, if your Stereo mic has "1/4 inch male phone plugs" Hosa makes and adapter that has 1/4 inch female plug to Male XLR connectors. The Mackie, and just about every mixer in the world these days has Female XLR connectors for it's microphone inputs. So that will handle tha.

I'm not sure what you mean by the "combo" amp. If it has XLR inputs you can use Tip Ring Sleve male output jacks to the output. If your amp as conventional 1/4 inch female input jacks. Than a simple
1/4 inch Male to Male Guitar Cable will work fine. DON'T USE A SPEAKER CABLE as it is uninsulated and you will get 60Hz hum.
I hope this helps,
That looks like a great quality mixer you have!
Happy New Year,
Mark

My akg perception 200 is not responding


Have you tried using a another XLR cable..,or are the other mics phantom powered condensers..ie try to locate if its a mic problem or the cable..2 other points are 1 - XLR leads for phantom mics need to be XLR to XLR male to Female plugs[ends] 2- is that often an XLR to XLR cable will be not soldered or wired right,so that the power [phantom power is not getting to the mic] so ensure you have a proper cable for that job...Sorry i can't be more specific but from reading your problem all these issues come to mind..If you have ruled all these things out,then it could be the capsule or loose joint or component in the mic which means contact AKG,pro audio services or find a DIY mic person to help..G luck!!

I buy a microphone, and I don't now where I have to plug it in, I's called i Carly Microphone, do I need something extra to use it, im trying to plug it in an guitar amplifier...


does it have a cable for it? it should. if it does then just plug it into the amp input jack. there is probably an on/off switch on the mic. i dont know if this is a fixed mic cable or if it is XLR type input on the mic. If there is a place for a cable to plug into the mic at the base of the handle, see if there are 3 pins in the jack of the mic. if so it is XLR, and the amp is 1/4inch so you would need a cable with XLR to 1/4"male. I would go with no shorter than 12 feet, but try to go with 20 to have enough room to move around. Hope that helps.
