Why not start with audio? 'Preamplifier and Power Amplifier'

Why don't you start audio? Preamplifier and power amplifier

This time, I expanded the base of music viewing, especially people who have no hobby or are interested in audio, but I do not know what to start with. I hope it will be helpful for those who want to enjoy music with better sound.

Music is heard in various forms, but the minimum equipment required to listen to good music is players, speakers and amplifiers.
Players are now smartphones and tablets playing iTune and Amazon music, record players playing CD players and analog records. The speakers are all familiar. And amplifier, this is the instrument that amplifies the music signal entered by the player (amplify amplify in English) and switches multiple music signals. With these three devices, the environment is ready to listen to music with good sound for the first time.

Even if the speaker knows that it's an audio beginner, is amp? It may be. If you have a player and headphones, you can listen to music.

So what is amplifier? It is. 。



"The amplifier is the job of finishing the sound in a better condition before making sound from the speaker."
Generally, the music signal output from the player is very small, so the amplifier amplifies the small music signal and sounds at the level that it can sound on the speaker. What is important in the audio world is how to deliver the signal of the played sound to the ear as it is. However, there are various types and characteristics such as high range, low area is emphasized, and each amplifier has sound characteristics in terms of warmth and coolness. It is also one of the fun of audio that you can encounter amplifiers that suit your taste and music genre.

In any case, amplifiers that amplify sound signals are indispensable for enjoying music with "good sound."

Preamplifier and power amplifier??


The amplifier is roughly divided into two types: preamplifier and power amplifier.
"Preamp"is an amplifier that connects music players (smartphones, CDs, record players, etc.) at the same time to select which equipment to listen to, and adjust the sound quality and volume. The amplifier (amplification) does not amplify the signal level, so there is no terminal to connect the speaker. So, if you select a playback machine to connect or you do not need an equalizer function to listen to records, you can say that if the power amplifier has even volume adjustment (you don't even need volume if it is a smartphone or tablet), preamplifier is unnecessary. However, if you put a word in the honor of preamplifier, the music signal that is played by preamplifier is beautifully arranged, and it is reliable to evolve one or two steps from high to low to rich and glossy tone.

The role of amplifying music signals sent by preamplifiers and players so that they can produce sound from speakersPower AmplifierIt is. The sound is transmitted from the power amplifier to the speaker. The power amplifier literally amplifies the signal sent so that the speaker can be driven so that the music can be heard. Most power amplifiers have a large, heavy transformer built-in power amplifier that strengthens the power supply to generate the driving force. Depending on the power amplifier's ability (depending on the strength), there is a difference in the speaker that can drive. If the amplifier is not strong to the speaker, the speaker's original ability cannot be demonstrated, and the speaker can not get a satisfactory sound even if the speaker is rough on the amplifier. In both cases, it is not possible to hear the ideal sound that can be expressed. Choosing something that matches each other to a certain extent is necessary to enrich the music life.

As mentioned above, amplifiers with separate pre and power parts are called separate amplifiers. When it comes to separated amplifiers, it increases the enjoyment of pursuing your favorite sound by combining different manufacturers.

The Puri and the Power Part are united."Premine Amplifier"or"Integrated Amplifier"It is called. Since each manufacturer has a lineup of power amplifiers with volume adjustment, it is possible to use it as a main amplifier.

For example,Bakoon Productsof
This power amplifier is small enough to be used on desktop. The input system has two lines: the RCA terminal on the back and the phonjack on the front panel. You can connect a mobile player or smartphone to the front desk, so you can connect to the CAP-1001 immediately after you go home and enjoy high-quality high-resolution music as it is. Although it is small, the sound is authentic and makes you listen to wonderful sounds that are unimaginable from the appearance.

And now a vacuum tube amplifier that fuses retro and future feeling



What kind of amplifier is a vacuum tube amplifier that we handle a lot in our shop?
It is an amplifier that amplifies the signal using a vacuum tube, but not only the amplifier, TV and radio were all amplified by the vacuum tube in the past. However, the demand for 3 high vacuum tubes that eat heat, production, and places decreased, and various electrical products were replaced by inexpensive and productive transistors. Audio equipment was not leaked as an example, and things using transistors became mainstream, and amplifiers using vacuum tubes were drastically reduced to the extent that small and medium audio manufacturers manufactured.

A common image from the past is that the transistor amplifier is a retro sound with warmth, such as "the sound is cold" and "there is no softness or warmth unique to the vacuum tube" compared to the vacuum tube amplifier I think that there is no feeling. First, the accuracy of internal components such as transistors and condensers has improved dramatically, and at the same time, technology has advanced overwhelmingly. It is a vacuum tube or a transistor to faithfully reproduce the sounds that will be played back in the original, but in the same way there will be no impurities and it will become a transparent and clear sound.

Manufacturing vacuum tube amplifiers.Astro Electronic Planning.The amplifier is very accurate, sophisticated and transparent, and is different from the image of conventional vacuum tube amplifiers. This is because Astro Electronics has a policy of "faithfully reproducing the original sound."

Now vacuum tube amplifiers are much easier to handle. There is no need for difficult adjustments, and beginners can enjoy it with confidence.

It is recommended for those who have just started audio, veteran audio fans, who have been away from audio for a while, but also want to listen with a good sound again.
