Of course, not every user of a personal computer pays attention to the quality of sound that comes from the speakers connected to a digital comrade. Most are comfortable with a quiet and not quite clean and high-quality sound, which inexpensive devices can produce. Given that the market for high-quality sound equipment is growing like mushrooms after rain, more and more people prefer not only powerful, surround, but also high-quality sound. How to make an amplifier for your own speakers?
It is impossible to imagine a single audio system without this component. This pleasure is not cheap, so for those who can not afford the purchase of expensive equipment in specialized stores, we recommend assembling a home amplifier for your own speakers. This advice will appeal to all those who design something pleasing. After all, it will be much more expensive to do it yourself than the standard and mundane bought at the store.
How to assemble an amplifier for speakers and how realistic is it?
Naturally, some electronics skills and knowledge are needed here. In terms of power, these devices can be different. Therefore, before constructing an amplifier for speakers, you need to decide for what purposes you need this device and with what equipment it will be used. If the sound amplifier is intended for a subwoofer or headphones, a certain set of parts will be needed, and for a sound card it will be completely different.
In order to make an amplifier for the speakers yourself, you need a good circuit (this is not a problem, since there are a lot of similar ones on the Internet, you just need to choose the one that suits you best), soldering skills, and details necessary for the chosen circuit. Basically it is a case suitable in appearance and size, a printed circuit board, an active filter, a stabilizer for microcircuits, an operational amplifier, a DAC, and a digital receiver.
After everything you need is purchased, you can begin work. It is better to buy initially expensive parts, since there can be no talk of cheap quality sound. After all, the amplifier for the speakers is done independently, so that the sound is clean and unsurpassed.
Begin with the preparation of the printed circuit board. You can do it with your own hands, but it’s better to buy it with other parts, because this is one of the main components of our amplifier. It can also be ordered from those who are versed in the manufacture of such devices.
After all the components are ready, it will not be difficult to assemble an amplifier for the speakers. The main thing is to do everything sequentially and according to your scheme.
Perhaps, after several hours of operation, the speaker will wheeze, which means that there is not enough current strength and you made a mistake by connecting the second crown in series, and not on direct connection. In this case, the voltage remains unchanged, and the current strength increases.
A correctly assembled circuit should not emit cod, any hum or noise. If any of the above is present, then you need to check the circuit again. Perhaps you did not solder any negative wire.
After all the components are mounted, all the parts are soldered, and the quality is beyond doubt, you can already connect your ready-made amplifier to the audio system. Even though it is one of the rather important components of an audio system, all other parts must be of a high standard. Only in this case you get a powerful and high-quality sound of the whole system in general.
And finally, mount the finished circuit in the case and arrange the amplifier for the speakers as you like.
