2
The best option is to buy an external interface with built-in MIC preamps. Typically, these devices come with a set of drivers, allowing you to simultaneously record and reproduce a signal from multiple inputs and to process various audio effects. If bought this audio interface, you will only need microphones and cords to them with the XLR (three-pin).
3
You can use external MIC preamps that connect to a common audio Board of the computer via line-in stereo input. The signal of one of the microphones when it comes on the left channel and the other on the right. For this you will need an adapter with a mini Jack (TRS 3.5 mm) - two RCA jacks (known as "Tulip").
4
All other options have been calculated on a fairly low budget, the quality will also be low, but emergency suit and they are.
5
Often two microphone connectors had a Chinese DVD player with karaoke function. If one of them you have, you can connect its line out with a stereo cable to the line input of your computer by connecting via the adapter as in the previous embodiment, and the microphones attach to the respective connectors on the player using cords XLR-TRS (Jack 6.35 mm). The quality of amplification from budget Chinese art is not very high, and the microphones from this country are highly susceptible to interference and feedback (high-frequency whistle from falling signal to the speakers into the microphone), but when working with headphones and a suitable option.
6
One could solder a small circuit with common shielding (negative) wire and separate the wires plus. All you need is a stereo cable, stereo jacks-Jack, two monarshey and, of course, a soldering iron and duct tape. But be aware that the signal level will be with this method of connection is extremely low and the noise level is high.
Note
When soldering cables, keep in mind that negative cable serves as a screen against interference. Use only shielded cables for satisfactory sound quality.
Useful advice
To connect to a computer it is better to use dynamic microphones. Condenser microphones need phantom power 48 V, in addition, they are more sensitive to background noise and interference.

Advice 4: How to solder two wires

The need to solder two wires may occur in very different situations, ranging from extending the cable of the appliance and ending with the creation of electronic devices. This will be done brazing depends on reliable operation of the appliance and the safety of its use.
How to solder two wires
Instruction
1
The connection method depends largely on the type of cabling. Can be three main options: both wire solid wire; both wires are stranded; single stranded, the second was solid.
2
Connection of solid wires can be run in two versions: spike two wires; twisting the wires and the subsequent spike. The first method use where wire not subject to mechanical load. The second use when extending the cables of the electrical appliances.
3
For solder two solid wires, strip them from the isolation of 1,5-2 centimeters. If the wire is oxidized (darkened), scrape it with a knife to Shine. Avoid touching your fingers to the cleaned surfaces on them remaining fat traces will interfere with soldering.
4
Will saladita, that is cover with a thin layer of solder, the solder wire. Do this carefully so as not to melt the insulation. Ensure that the wire is not springy – runaway with it a drop of solder can fall into the eye. So ludite wire on the plate, and not on weight.
5
Use when soldering rosin or its solution in alcohol. In the absence of rosin, use aspirin. Carefully zheludev both wires, connect them overlapping on the plate, then take a soldering iron a drop of solder and propagte junction. Then allow the connection to cool without moving the wire. After solidification of the solder, turn the wire and gently probajte second side. Fix when soldering both wires.
6
The connection must be insulated. This can be done in two ways: to put on one of the wires before soldering, a piece of PVC cambrica, then, after sealing, to move it to the connection or insulate the soldering with electrical tape.
7
When connecting stranded conductor, remove the insulation by 3 cm, Carefully strip the wire with a knife, then firmly twist them together. The place of lay propagte, making sure that the solder covers the connection from all sides.
