How to connect XLR plug to Combi-Connector socket

The input to the laptop usually requires a stereo or TRS type 1/8 inch plug If the mic has an XLR type connector, you need a special cable that connects the XLR pins 1 and 3 (adjacent pins) to the shield of the 1/8 inch plug and pin 2 of the XLR connector to BOTH the tip and ring of the little stereo jack. Such a cable is not commonly available so the best is to make one from parts you get at Radio Shack.

If the mic is working on other camera's, what about the adaptor ? If there is a possiblity of checking the mic and the adaptor together on other equipment ? Use another mic with the same plug as the camera, ie. PC microphone (you can even test by using an earphone, the earphone can be used as mic) If it works then the XLR mic with adaptor is the problem. If ther other mic (used for testing) also did not work then the microphone jack (socket) in the camera is defective or the gain setting of the camera is set to minimum.

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). .

All microphones have to be hooked to an amplifier to work. The socket at the bottom with the 3 pins in it is called an XLR jack. You need to plug an XLR cord into that and then plug it into an amp that has an XLR or 1/4 inch microphone input (using an adapter).

If she just wants it for looks, then no, you don't need to plug it in.

Correct connections to connect your keyboard to your roland amp, and then the amp to the PA would be:

Two mono 1/4" jack (regular guitar leads) leads to connect the sockets labeld L and R on your P90 into channel 2 L and R on your amp. (channel 2 is better as you cannot overload it like you could on channel one, which has enough gain for microphone)

Then, using either the jack or XLR (XLR would be better if your PA mixer can accept them) sockets on your amp labeled LINE OUT, hook up your roland amp to your PA. Make sure to use the correct line outs on the top panel, NOT the stereo link or Sub outs on the back.

That will not work. The Beta 87H/C already has a preamp built into it. That preamp requires phantom power. The MX1BP is another preamp, so you would not need it, due to the preamp that is built in.

If you do not have phantom power available, then purchase an external phantom power supply.

You need to connect it to a mixer first and from there to an amp/speaker combo. This microphone needs phantom power and you can only get it via the mixer. Also, you can control the volume via the mixer. Depends on what kind of speaker you have (active or passive) you will need an amplifier. If you're trying to plug it into a guitar amp, it won't work without a mixer. Plug the 3-prong xlr male cable into the input of the mixer. The 3-prong female xlr end goes into the mic.

There are many standards of microphone connectivity with 3 pin XLR (cannon) style plugs. It depends on where in the world you are as to the favoured standard,
Your microphone usesthe following::

Pin 1 ground (white) 2 +ve or hot (red) 3 -ve or return (black)

Another way to work out what wires connect to what, is to remove the cover of one of your XLR-XLR microphone cables exposing the connections it favours, plug the connector into the mics scoket , and use the connections to the cable guide you in resoldering the connections back on.
The same connections can be veiwed in the user manual here

Headset connection: Blue wire to Pin 2, White wire to Pin 1, Yellow wire to Pin 3. Connect Pins 1 & 2.
Microphone connection: Black wire to Pin 3. Red wire to Pin 2. Ground wire to Pin 1.
I am using a male/female 7-pin XLR connector assembly to black box. I am using two 3-pin XLR connectors, one for SM2 microphone function, one for SM2 headset function.

It could be the wiring in the 1/4" jack in your amp. Check the metal contact plates on the 1/4" jack in your amp and see if they are getting contact to the jack. Sometime they get bent.

If the XLR end of the cable can be serviced, check the ground connection to the cable and see if its good.
