- Computer, microphones, audio cables, adapters.
The best solution is to buy professional entry-level audio interface. Such devices are inexpensive and available in different versions. There are options to connect to USB, Firewire, PCI, and PCI-E ports. The choice depends on your goals and on the configuration of your computer.
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).
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").
All other options have been calculated on a fairly low budget, the quality will also be low, but emergency suit and they are.
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.
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.
When soldering cables, keep in mind that negative cable serves as a screen against interference. Use only shielded cables for satisfactory sound quality.
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 2: Where to connect microphone to computer
Modern computers support different input and output sound. You can connect virtually any microphone for making calls, recording your own voice and its subsequent processing. For this you need to connect the device to the computer and make necessary settings.
The microphone connection to the computer is performed using an appropriate socket on your sound card located inside the case. Any modern PC or laptop has two or three holes for mounting devices to work with audio. Usually sockets to connect speakers and microphones are located on the rear panel of the computer or on the side of the laptop. Also some desktop systems allow you to connect the device through the front panel of the computer, which in turn is connected with the sound card.
Connector for a microphone is usually colored in a pinkish hue, and on some panels the socket marked with a special icon. Insert the microphone plug into this connector.
To verify the device after the installation of the plug into the socket, open the menu "Sound". To do this go to "start" - "control Panel" - "Hardware and sound" - "Sound". In the window that appears, select the "Recording" tab Is Microphone. Click "Properties".
Go to the "Levels" and adjust the desired settings. To increase microphone volume move the slider to the "Microphone" to the right. To enhance the sound, you can also use the "microphone boost".
To check the quality of the sound recording device, in the same window select the tab "Listen". Connect your speakers and headphones to the computer and check the section "listen to this device". Click "OK".
Some modern computer microphones are connected to the USB connector. Insert the plug of the device into the computer and install the driver that is supposed to come with a microphone included. If there is no disc, download the drivers by going to the manufacturer website of your device and selecting the relevant section in the menu resource.
If the microphone is not working, check the connection to the computer connector and read the cable device for damage.
