If you've been trying recently to get a deeper understanding of power amplifiers, you have probably come across terms AC amplifier and DC amplifier. What was your first thought? Was it Alternating Current and Direct Current? Well, terms AC and DC in amplifiers don't exactly refer to current. These terms refer to the coupling method between different stages of amplification. Our article is designed to help you understand the working principles of each of these two amplifier types, and explain the differences between AC and DC amplifiers. What is The Meaning of AC and DC in AC/DC Amplifiers? AC in AC amplifiers tells us that different stages of amplification are coupled with a capacitor or a transformer. These capacitors/transformers are, therefore, known as coupling capacitors/tr...

Is JBL better than Bose? That’s one of the most common questions people ask us every day. A few weeks ago, we did try to answer this question, or rather give you some general information about each brand and about their Bluetooth speakers. However, we don’t think that comparing just two brands and not two specific speaker models, can give you the right answer. The only way to make things clearer for you and give you proper advice is to compare just two speakers, list their pros and cons, and give you our verdict. So, instead of comparing brands, we are today comparing two similarly priced Bluetooth speakers - Bose SoundLink Revolve and JBL Charge 4. Let’s see which one is better. Bose SoundLink Revolve comes from the SoundLink series of portable Bluetooth speakers that also in
Are you thinking about buying a new piece of audio equipment and you’re not sure which brand you should look into? Both JBL and Bose have been praised by their customers for their high-quality, durable speakers. But, is JBL better than Bose? Or is it the other way around? Well, today, we will try to help you get answers to these questions. About JBL As stated on the JBL website, the company was founded over 70 years ago. Its founder, James Bullough Lansing, whose initials form the name of the company, manufactured speaker drivers for radios with his business partner. What started as a small idea turned into a company worth millions of dollars. Today, the company is owned by Harman International Industries. The holding company of Harman International Industries, by the way, is Samsu
Buying a soundbar is an excellent solution when you don't want to spend too much but feel that you need something louder than your TV speakers.

Speakers are widely popular audio devices and they are produced in many versions, shapes, and colors. They can be big or small, wired or wireless, you can buy a single speaker or a speaker system. They can be found anywhere and everyone wants them. We may think we know everything about them but there is actually one less known type that we don’t write about so often. These are PA speakers and in this article, we will try to present them to you in the best possible way, list their positive and negative characteristics and give you a short buying guide that should help you decide which PA speaker set is best for you. What Are PA Speakers and Why Do We Need Them? Before we even start, let’s find out what PA stands for. It actually means “public address” and these systems are made in orde
The main reason why we decided to write about dynamic and balanced armature drivers is to make people aware of small units hidden inside pretty earbud and headphone enclosures. We have noticed that more and more people make their choices based on a device’s design. Of course, we don’t want to insinuate that those buyers don’t pay any attention to the device’s specs but if they aren’t really familiar with all those abbreviations, numbers and units of measure, they are definitely more comfortable to make their decisions based on the looks and price tags. Headphones and speakers, as well as all the audio equipment and hearing aids, consist of many small parts that work together to deliver the best possible sound and satisfy their users’ needs. We don’t want to say that the performance
Music is the inseparable part of our lives and we are constantly exposed to its influence no matter where we are and what we are doing. Music is in every café, in every shop, even in the streets. Many people can’t imagine working, studying or even driving in complete silence so they play some music. If music helps us so much in all of these situations, imagine how great it is to come home and relax after a hard day with a few favorite songs played through your home speakers. Many people decide to buy 3-piece speaker systems because they are easier to set up than home theater speakers and they offer amazing sound quality. Some of the best solutions in these situations are floor-standing or bookshelf speakers that can fit most of the houses or apartments because they are simpler than
Surround sound systems have become popular only recently and this is what makes people think of them as of some new technology. Well, this is far from the truth as surround sound systems came into existence with the introduction of surround sound audio formats back in the 1930s. As you could probably guess, surround sound systems first appeared in the film industry and Disney was responsible for this innovation. At the time, the technology was too expensive for application because it required numerous speakers to create the effect of surround sound in a movie theater, so the creators gave up on it. This question was raised again in the 1950s (again, in the film industry) but its real expansion didn't start until 1975 when a new sound format Dolby Stereo appeared (you can find a more thorou...
If you’re reading this, you are probably interested in setting up a new or upgrading your old surround sound speaker system. These systems have been very popular during the last two decades and the number of their users is increasing every day. If you have read about these speakers before or you’ve heard them, you are probably not wondering why they are so popular. Surround sound systems consist of at least five speakers and at least one subwoofer. (Of course, you can get a smaller system with less speaker that imitate surround sound very well but that doesn’t mean the final result will be good as expected.) Those 5.1 systems are actually the most popular option but those who have big houses usually want to equip it properly and they buy larger systems – 7.1, 7.2 or even 9.2.4 (4 stand
