How to choose the best amplifiers?
They are known as amplifiers or Power amp as a group of electrical components that manage to increase the voltage and power of a signal, making it stronger in its process. Therefore, amplifiers work by boosting the signal, so you can make speakers such as woofers, subwoofers, loudspeakers, and tweeters sound much louder. Given so many models that the market offers, we wanted to make this guide to buy the best amplifier, with which we want to help you choose the model that best suits your needs.
When making any choice or comparison of amplifiers, we must take a series of relevant aspects into account, as well as be attentive to all the advice that the most experienced users in the world of audio and amplifiers can give us. As in practically all electrical devices, the materials with which it is made play an important role, marking the durability and resistance of this device. In addition, of course, it defines the price of the amplifier.
Since both the architecture and the external materials are as important as the materials of the internal components and are usually a determining factor when making your final choice. Ask the opinion of any audio professional to reaffirm the general belief that quality comes at a price. This means that an instrument made with quality materials will cost much more than those made with simpler materials. Therefore, if you are aware of how much the amplifier you are looking for costs, we recommend you look at this aspect.
Difference Between Valves and Transistors
When it comes to audio, in the world of amplifiers there are two main types: while some work with valves, others work with transistors. It should be clear that, at present, most of the audio and video receivers that you find on the market are of the transistorized type, although, according to professional users, these devices emit slightly colder sounds. If you’re looking for an inexpensive model, make sure parts are readily available.
On the other hand, amplifiers that work with valves require much more maintenance, so being heavier and require heating to function under adequate performance. However, some audiophiles still willingly purchase these types of systems. However, with these positive aspects in mind, in recent years, many of the manufacturers have taken the initiative to launch a line of hybrid amplifiers, which generally work by linking or mixing a tube-based amplifier system to a transistor based amplifier.
Whenever we go to buy a new amplifier, one of the aspects or characteristics that leads every list of recommendations is the power of the amplifier motor. Of course, the power will measure the quality and force with which the amplifier will increase the sound level and clean the defects. Although you can get a cheap amplifier on the market, that device will most likely not have the same sound quality as a slightly more expensive but more powerful model.
It is very important to understand at first that power is an element that at all times is referred to a load, or electrical resistance that is measured in ohms and is called impedance. In the case of amplifiers, manufacturers usually promote the power in watts for each channel of the amplifier in question, however, they do not usually specify what impedance the figure refers to.
In addition, it is recommended that, when making your purchase of the audio and video receiver, that you look at its electrical consumption, so that you can see if the device is going to be powerful enough to support all the watt consumption which can be seen in the technical sheet.
number of channels
Another key aspect that surrounds quality amplifiers is the number of channels that the audio and video receiver has. Keep in mind something very important, the total number of channels that an amplifier has will give you an immersive experience at a greater or lesser level, so it is normal to find that professionals are usually very clear about the number of speakers they are going to connect.
Frequently asked questions
Q1: How to use an amplifier?
Make sure you have connected the desired speakers, according to the number of output channels that I have on the device. Then, connect the device that contains the music, such as a USB, SD, in case you have those inputs. Otherwise, you will be able to connect your Android devices using Bluetooth technology, as well as pair your wireless headphones. Next, when you choose the song you want to listen to, put “play” on it and graduate, either with the control or with the adjustment knobs, the sound level, treble and bass, among other sound values.
Q2: How to make a circuit for audio amplifier?
It is important to have a diagram that represents the entire circuit, as well as all its symbols, so that it weighs in which part each component goes. We begin to solder each component in its respective place. It is a recommendation to be aware of the difference between the negative elements, which differ from the positive ones by having the paras longer than the seconds.
Then, the components must be soldered, always making sure to follow the indications of the diagram that you are using as a base. By using a tester we will be able to know which legs of the potentiometer are the ones that go directly to ground and which of the two is the positive and the negative. Finally, after making sure that each leg is in place, we connect the entire system together with a 9V battery.
Q3: How to remove noise in an audio amplifier?
We recommend you start by checking the chassis screws, making sure they are well secured. On many occasions it is a small loose piece. On the other hand, you can look at the place where you have connected the amplifier, since sometimes these devices can emit a noise due to a ground loop that is in the place where the amplifier is installed. Noise can also come from a ground loop caused by a plug that has multiple appliances plugged into it. You can try unplugging the amp and unplugging it from the power outlet.
Q4: How to connect an audio amplifier?
Connect the amp to a power source first, as these devices typically use up to 110 volts of AC power. After connecting the power cable to the wall, connect the speakers to the amplifier. The stereo models have outputs for several speakers, depending on the model, placing the right and left speakers in their corresponding places, guided by the color or the reference letter. Next, connect audio components such as a DVD player or turntable and set the amplifier mode to “CD” or “AUX”, as appropriate.
Q5: How to calculate the power of an audio amplifier?
Activate the amplifier circuit. Turn on the voltmeter that you are going to use to make the measurement and choose the “volts of alternating current” scale and then proceed to measure the voltage on the output cables. Also, write down the voltage measurement. If in case you are using a pre-built unit, you will need to obtain the impedance or resistance for the speakers or headphones that is noted in the instruction manual. Write that number down on a piece of paper and proceed to multiply by the voltage values and divide that result by the impedance value you wrote down.
Q6: How to make a 1000w audio amplifier?
To be able to build a 1000W audio amplifier it is very necessary that you have an intermediate level, in terms of knowledge about electronics. Before building the circuit, it is highly recommended that you read the schematic diagram carefully, as well as the bill of materials found on the diagram itself.
Q7: How to know if the audio amplifier is damaged?
To know if the amplifier is damaged we can give you several recommendations. First turn on the switch and if nothing happens the problem is in the power section. Turn off, unplug, and unscrew the entire box to inspect the fuse. If it is dark or dirty inside, it is a sign that it may be burned. Replace it with a similar fuse, guided by the value indicated on the base of the fuse.
Q8: Who created the audio amplifier?
The first audio amplifier was invented by a man named Le DeForest, who introduced an archaic triode vacuum tube system. It was a system that was created from Audion and managed to be further developed by DeForest. The main difference was that the triode had three components while the diode only had two.
