Purchasing guide

The aim of amplifiers is to transmit incoming audio signals to speaker-type devices at the required level of power and loudness with the least amount of distortion feasible. They have a lengthy history and are now found in nearly anything that generates sound, from phones to laptops to televisions. However, if you choose to purchase an external one in order to enhance what you currently own, things might become rather difficult.

The purpose of this guide is to assist you in selecting the best amplifier based on how it reproduces sound, compatibility with the speakers to which it is connected, output quality, connection, and other essential technical aspects.How an audio amplifier works -2022 updated

The class in which the amplifier is framed indicates how the input signal is processed in order to generate the output signal. There are numerous categories, but five are sufficiently popular to warrant inclusion in this guide.

We propose that you pick an amplifier version from class A at a reasonable price if you want a model with a very high level of sound reproduction. However, bear in mind that these models have a poor efficiency rating of 20%, which means they use a lot of power, operate continually, and generate a lot of heat, necessitating extremely effective ventilation.

The B-class versions are more efficient in terms of power consumption, but are more prone to distortion and have lower sound quality.

As predicted, the A / B class combines the best of both worlds, maintaining the precision of type A variations while improving energy efficiency. They are frequently utilized in home audio systems and automobile stereo systems.

The G and H versions allow for supplementing the power utilized to create the output when the received sound signal’s strength demands it, while maintaining a level of energy efficiency comparable to the A / B variants.

The variations in category D achieve the maximum energy efficiency, up to 80 percent, by wasting less electricity and producing less heat. They are more smaller, lighter, and more pleasant to use, and provide high-quality sound.

However, for the most discerning, we want this technological version to perform admirably on low waves while having difficulty reproducing loud sounds properly.

Compatibility: One of the factors to consider when selecting the right model for your electrical equipment is the RMS power (root mean square or average). This must not exceed the figure specified on the speaker or speakers with which you utilize it, regardless of whether we are talking about headphones, laptop speakers, or vehicle speakers.

For example, if you have a single 100 watt speaker, we suggest an amplifier with an RMS power of between 80 and 100 watts; for two 100 watt headphones, we recommend 150 – 200 watts; and for three 100 watt speakers, we recommend between 200 and 300 watts.

To ensure proper pairing, you must determine the RMS value sent by both the speakers and the amplifiers.How an audio amplifier works -2022 updated

The number of channels indicates the number of outputs or speakers that the device can support. If you are using two speakers and a subwoofer, you will need a three- or four-channel model. Additionally, the impedance or resistance of the circuits is required for proper connection.

As a general guideline, you should use a speaker that has an ohmic value between 8 and 10 times that of the amplifier. For instance, if you are using 200ohm headphones, you will require a 20-25ohm model.

Along with the speaker’s acoustic sensitivity, the impedance of the speaker might indicate whether or not you require a low-cost amplifier to boost the sound. In general, such an increase is necessary when the impedance is large (more than 100 ohms) or the sensitivity is poor (below 100-110dB).

Frequency and distortion: The response frequency indicates the amplifier’s ability to reproduce sounds over the whole human hearing range, from deep bass acoustics at 20Hz to the highest treble at 20000Hz.

A low amount of distortion results in a clear sound that is extremely near to the signal that entered the device. Numerous reviews of the finest amplifiers advocate units with up to 0.5 percent THD (total harmonic distortion).

If you are unsure whether to go with analog or digital amplifiers, we can tell you that both provide a balanced combination of advantages and disadvantages.

The analog varieties are favored for their warm, genuine sound. The circuits’ simplicity also makes them easier to fix for people experienced in electronics. On the other hand, they can be more expensive than digital ones and can overheat more quickly with prolonged usage.How an audio amplifier works -2022 updated

While digital versions are more recent, they have advanced sufficiently to give accurate sound reproduction and are frequently more inexpensive, making them easier to replace and therefore offsetting the difficulties of repair.

Additionally, the decision is dependent on the kind of source signal; for laptops, MP3 players, televisions, and smartphones, a digital amplifier or an analog model with DAC is advised (digital to analog converter).

Fixed or portable: A fixed version is ideal for individuals who spend a lot of time at the office and listen to music while working or who want an amplifier for their home media system.

Rather than that, if you want to boost the performance of the headphones you use on the road, the finest amplifier model will be tiny and portable.

The operation of an audio amplifier

If you are concerned with acquiring as much technical knowledge as possible, you will undoubtedly want to understand how an audio amplifier works. In this article, you will learn enough about the subject to get started and, if you are a sound quality connoisseur, you will learn how to choose the appropriate equipment for you.

Although it is a device that you use and have at hand, you may not know how an audio amplifier works and you can document yourself in this article. Amplification is a term that refers to an electromagnetic or electrical component that is designed to stimulate an electrical signal.

The gain of an amplifier is defined as the ratio of the input signal to the output signal; in other words, an amplifier with a gain of 2 twice the input signal. Gain is defined in decibels (dB) and is determined by the manufacturer for audio amplifier models.

 

Amplifier distortions

Along with boosting the strength of an electrical signal, an amplifier must address additional critical issues such as correct replication of the input signal, even if it varies and is not constant in terms of frequency and amplitude (eg loudness for audio amplifiers).

An audio amplifier performs better at certain frequencies and not at others, and the frequency range across which it operates is referred to as the bandwidth. If the amplifier’s input and output frequencies are not precisely reproduced, it exhibits a nonlinear frequency response, amplifying certain sounds more than others. Occasionally, this can be accomplished deliberately; for example, with extremely tiny headphones, the bass is enhanced differentially.

In principle, a representation of the output signal would be completely linear; but, in fact, the output signal’s form would differ from that at the input, a phenomenon known as distortion.

Distortions can be linear or frequency-dependent, caused by variations in the amplification coefficients, or nonlinear, caused by the amplification process itself. They occur primarily because the audio devices used do not exhibit linear characteristics, and additional harmonies appear that alter the shape of the output signal.How an audio amplifier works -2022 updated

What exactly is feedback?

Those who work in the sphere of entertainment, particularly in concert organization, are extremely familiar with this word, which is manifested by a deafening sound.

This is because the stage microphones were not correctly positioned, either turned or too close to a speaker. In this instance, the microphone will also pick up on the speaker’s signal, which it will amplify, producing that extremely unpleasant and loud sound.

Amplifiers of various types

There are several audio amplifiers on the market, and to make it simpler to locate a suitable variation, they are classified according to certain characteristics.

Thus, depending on certain characteristics, such as voltage, power, and current, you have several options, including: conventional amplifiers – where the gain is the ratio of the input and output voltages; transconductance amplifiers – useful when you want an output current proportional to the input voltage; or a resistance amplifier, which is the polar opposite of a transconducting amplifier and has an output voltage proportional to the incoming current.

Additionally, amplifiers can be categorized according to their operating frequency, with the band in which they work optimally noted. Thus, the audio waves you perceive span a very broad frequency range of 20 Hz to 20,000 kHz. The amplifiers are constructed in such a way that they perform optimally in a specific frequency band, and because the manufacturer explicitly specifies the band, you may pick what you need.

Another categorization, based on certain properties, is denoted by capital letters of the alphabet or combinations of capital letters, identifying several classes of amplifiers from which you may pick based on your objectives: win, linearity, or efficiency.

Thus, class A amplifiers are typically focused on linearity, providing the highest output quality with the least distortion, but they are also bigger, heavier, hotter, and less efficient to achieve these objectives. In class B, you will find some of the most convenient models in terms of price, efficiency, and linearity. To reconcile the two features of the aforementioned classes, class AB was introduced as a compromise approach, combining the linearity of class A with the efficiency of class B.How an audio amplifier works -2022 updated

The C-Class is distinguished by a significantly higher efficiency rating than prior models, at over 80%, and a high-performance sound quality. Regrettably, the distortion levels of amplifiers in this category are significantly greater, which is why they are employed less frequently.

Other groups of criteria, such as D, E, F, GH, I, S, and T, have arisen more recently, though they are less often employed. Those in class T are particularly interesting since they are contemporary, have a very clear sound, and are significantly more expensive than those in the other classes displayed. A more handy choice are those of the GH class, which are more affordable and yield up to 80%.

Amplifiers can also be classified structurally; there are models with vacuum tubes, which were among the first models and were inefficient, large in size, and despite the fact that they emitted numerous distortions, they fell into the category of even order, being registered as very pleasant by the auditor; there are models with solid-state transistors, which were among the first models and were inefficient, large in size, and despite the fact that they emitted numerous distortions, they fell into the category of even order Around the 1950s and 1960s, transistors changed audio technology, but they amplified all input signals equally, incorporating background noise; since the 1980s, we have progressed to sophisticated integrated circuits that selectively amplify, eliminating background noise.

The first amplifier using vacuum tubes in a triangle debuted in 1908, with the first patent registered in the United States of America. It belonged to Lee de Forest, an engineer and physicist who desired to build a radio. It is regarded the “father” of the amplifier and evolved from it, becoming indispensable in a wide variety of areas, but particularly well-represented and well-known in the audio field.How an audio amplifier works -2022 updated

Frequently asked questions

Is it more cost effective to purchase a secondhand audio amplifier? – Justifications for and against

If you are looking for a low-cost yet high-quality amplifier for headphones or speakers, you are almost certainly going to seek for used models. When comparing new and used models, it is necessary to examine many key factors, including the price, the degree of wear on the product and model, the potential of obtaining a warranty, and the ability to test the product beforehand.

In terms of pricing, you will truly save money by purchasing a used model, especially if it is a model that is at least a year old and is no longer regarded to be the newest generation. Prices might go up to 40%-60% of the market in some instances.

However, this benefit comes with the danger of purchasing a faulty device that requires repair, particularly if you order online and do not have the opportunity to test it. In such purchases, speakers and amplifiers are regarded to be items with a medium to low risk level.

However, the experts urge that you carefully choose vendors, preferring those who are enthusiastic about music over amateurs, and that you ask as many questions as possible regarding the goods.How an audio amplifier works -2022 updated

Is it possible to locate the audio amplifier scheme online?

You can readily obtain audio amplifier schematics online, either as an image or as a pdf file with a download option. Most provide implementation details, and you can also utilize numerous video tutorials to help you grasp the notations.

What use does an audio amplifier serve in conjunction with a mixer?

You will require a mixer amplifier model if you wish to work with many audio inputs and combine them into one or more outputs, depending on the possibilities.

Is it OK to improvise a casing for the audio amplifier?

If you have the requisite experience building an amplifier from separately purchased components or if the original casing is severely damaged, you may simply improvise a case. You can easily find guides on the Internet that will take you through the process of creating a cardboard, wood, or even metal version, depending on the resources accessible to you.How an audio amplifier works -2022 updated

What does the term “class D audio amplifier kit” refer to?

A module with a class D audio amplifier is also available in an analog form, often using transistors, that is more energy efficient than the A, B, and A / B versions.

These products are smaller, lighter, and incorporate technology that minimizes heat dissipation via heat, resulting in an efficiency of up to 80%, which implies that only 20% of the current entering an amplifier is converted to thermal effect.

As with versions A, B, and A / B, the kits contain connecting cables, speakers, microphones, and / or headphones for real-time monitoring of the processed sound.

How to properly connect an audio amplifier to a pair of speakers purchased separately

For those inexperienced with the operation of such a device, even simplified management systems on amplifiers might appear difficult, especially when purchased separately from the speakers.

In this instance, in addition to the operational parameters that indicate the device’s performance, you must also consider the device’s compatibility with the speakers.

Discover in the lines below the fundamental components you must consider when properly connecting the speakers to the audio amplifier.How an audio amplifier works -2022 updated

Impedance

This word refers to a device’s resistance to current flow and is measured in ohms ().

The impedance value is specified in the technical specifications of the amplifier, often as an interval, such as 8 – 12 ohms, and of the speakers, which typically have an impedance of 4 to 8 ohms.

A basic rule of thumb is that the ideal amplifiers for your speakers will have impedance values that are less than or equal to those of the speakers.

The authority

The simplest approach to determine the correct amplifier version for your speakers or the finest speakers for the amplifier you currently own is to examine the speakers’ technical specs to determine the suggested power.How an audio amplifier works -2022 updated

However, it is critical to understand that what you are interested in is the average continuous power, denoted by RMS, which represents the amplifier’s energy output most of the time, not Peak Power, which represents the amplifier’s occasional values, milliseconds, generated to respond to the needs of digital devices such as laptops or smart TVs.

Sensitivity

Alternatively, the sound pressure level (SPL) is expressed in decibels (dB) and indicates the volume of a speaker when placed 1 meter away from it and powered by 1 watt. For example, at the same distance, a speaker with an 84dB SPL will sound slower than one with a 91dB SPL. According to experts, you only require an amplifier if these levels are less than 100dB.

What you should keep in mind while making your selection is that this gadget requires double the power to achieve a 3dB increase in SPL. Therefore, if your speakers produce 85dB and you need 100dB, you will require ten watts.

Another factor to consider is the distance from where you are listening to music, as the sound is lowered by 6dB for every doubling of the distance. Thus, a 100dB speaker will produce 94dB at 2m, 88dB at 4m, and 82dB at 8m, and so on.

Which is why, in a 400sqm club, a kit with a greater power audio amplifier is required than in a residence with maximum 23sqm rooms.

Channel count

If you have two speakers, you will need a two-channel amplifier; if you have two speakers plus a subwoofer, you will need a three- or four-channel amplifier; and if you have four speakers, you will need a four-channel amplifier. As a result, it is a good idea to plan ahead and determine how many speaker-type devices you will utilize.How an audio amplifier works -2022 updated
