Virtually every home has such deviceslike a microphone and headphones. The first is used to record music, talk with friends on the Internet, sing in karaoke, etc., the second is needed to listen to songs or talk. Very often, even ordinary users are faced with such a problem as a low signal level. Because of this, the microphone does not work well even in karaoke, and the headphones do not allow the mid frequencies to be heard, and the low and high frequencies are heard rather poorly.
The microphone will help to solve this problem.preamplifier. Even good quality dynamic microphones are characterized by low sensitivity, so they are not workable on modern computers, where sound cards perfectly perceive only electret devices with high sensitivity. One cannot do without a preamplifier, because only it can amplify a low signal to a linear level.
Most audio interfaces and mixers are alreadyThere are built-in devices that amplify the sound, but they do not provide the sound quality that a preamp for a microphone provides. When choosing this device you need to be careful, because each unit sounds different. It is not enough to buy an expensive device with the best characteristics, it should still fit the microphone.
If a professional recording studioIf you can afford to purchase several similar devices and experiment with sound, then for home use, this is often an unbelievable luxury. Therefore, buying a microphone preamp, you need to pay attention to certain of its technical characteristics.
Devices are lamp and transistor.There is an opinion that the tube gives the sound velvety and warmth, but this can be said only about the most expensive models. You need to choose a mic preamp with a certain number of input channels. It depends on the purpose for which you intend to use the device. Ultimately, you need to calculate how many microphones you plan to connect to it simultaneously.
Most devices provide phantompower supply, but you still have to make sure it is available, otherwise condenser microphones will not work. You also need to pay attention to the presence of a low-pass filter, which will allow you to cut off unnecessary low-frequency interference and remove the effect of strumming and nasal. There are a number of characteristics, but their choice is a matter of taste for each consumer. To buy a good microphone preamp, you need to listen to it. After trial use of several models it will be clear which device is better. Please note that it is better to check the preamps with the microphone with which it will work in the future, that is, with yours.
If the microphone is responsible for the sound recording quality,This headphone is for its playback. Only a high-quality model will allow you to listen to the work and analyze it. But the problem lies in the fact that expensive models have great resistance, because of which some frequencies are not heard or are heard very poorly. A headphone preamp will allow you to properly adjust their sound. Also, the device allows you to send sound to several headphones at the same time, which is convenient for listening to audio recordings by two or three people.
