How does an amplifier work?
Amplifier is an electromagnetic component that boosts and amplifies the electric current passing through it. It receives the input signal and boosts it many times before feeding it into the output device. The basic function of an amplifier is to turn a small electric current into a larger one. If you want to boost a constant electric voltage, then you can use a transformer. But if the input electric current is a small pulsating one, then you can use an electromagnetic relay to amplify it. A relay couples two electric circuits together so that when a small current flows through one of the circuits, a much larger current flows through the other. If you want to amplify a fluctuating signal, then you can use a transistor-based amplifier. Base, emitter, and collector are the three wore connections of a transistor. You can give input current between base and emitter, then you will get a much larger output current flowing between emitter and collector.
Due to the clipping and distortion, there is a limit to how much an amplifier will boost a signal. The one and only solution to overcome this limitation is to connect more than one amplifier together.
Will amplifiers improve sound quality?
An amplifier will make your speakers play louder and sound better. They improve sound quality in a number of ways. The fundamental function of amplifiers is to modulate volume and they also impact sound linearity and tone. Even though an amplifier’s main job is to boost signals, it can also affect the quality of sound like the fidelity and how much it eliminates distortion. But the sound quality not only depends on the amplifier but also every other component making up the system and the external factors in which the audio is played.
Factors that determines the quality of the sound produced by the amplifier
Here are some of the technical characteristics of the amplifier that determines the quality of the sound:
- Output power: Output power of an amplifier is the power of the electric current the amplifier is giving to the output device. This may differ depending on the load impedance of the speaker that is connected and is limited by the distortion.
- Distortion: Distortion is the level of unwanted signals that is present at the output of the amplifier with respect to the input signal.
- Gain: It is the relationship between the output power and the input power of the signal and is measured in the decibels(dB).
- Frequency response: It is the relationship between the input and output signal levels for the set of frequencies in which the amplifier works.
- Sensitivity: It is the minimum signal level at the input that can generate the maximum output power on the load that the manufacturer has specified.
- Signal-to-noise ratio: It is the difference between the level of the output signal and the noise level and is measured in dB.
Types of amplifiers
Below given are different types of amplifiers and their working principles.
Audio frequency amplifiers: They are used to amplify signals in the range of human hearing that approximately ranges from 20Hz to 20 kHz. Audio frequency amplifiers are generally used to amplify the low level signals from microphones. They receive the amplified input from a series of voltage amplifiers and then provide sufficient power to drive loudspeakers.
Intermediate frequency amplifiers: They are tuned amplifiers used in radio devices, TV sets, and radar devices. IF amplifiers provide the majority of the voltage amplification of a tTV or radar signals, before the audio or video information carried by the signal is separated from the radio signal.
Radio frequency amplifiers: RF amplifiers are tuned amplifiers in which the frequency of operation is done by a tuned circuit equipment. They are used in the earliest stages of a receiver and are low noise performance.
Ultrasonic amplifiers: It is an audio amplifier handling frequencies from around 20kHz to up to about 100kHz ranges. Ultrasonic amplifiers are usually designed for specific purposes such as ultrasonic cleaning purposes, remote control systems, etc.
What is a stereo amplifier?
Wide band amplifiers: Wide band amplifiers are used in measuring equipment such as oscilloscopes and they have a constant gain from DC to several tens of MHz range.
Video amplifiers: It is a special type of wide band amplifier that preserves the DC level of the signal and is commonly used for signals that are applied to CRTs or other equipment.
Buffer amplifiers: They are specialized amplifiers and are placed between two other circuits to prevent the operation of one circuit affecting the operation of the other circuit.
Operational amplifiers: Operational amplifiers or opamp are designed for the early analog computers where they were used for mathematical operations such as adding and subtracting. They are commonly used in ICs and in complex integrated circuits for specific applications.
What to look for in a stereo amplifier?
Here are some of the characteristics in which you have to pay attention to when purchasing a stereo amplifier.
Compatibility: This is the most important thing to pay attention. You have to check whether the amplifier is perfectly matching with your speakers and for this you have to consider three characteristics, power output, impedance, and sensitivity.
Connection: Check the input and output ports and based on the number of t6he ports and type
of connection, you will know which devices you can use with that specific model of stereo amplifier.
Pre-amp, power amp or integrated: Decide whether you want a pre-amplifier, power amplifier, or integrated one according to your usage.
How do I choose a home theatre amplifier?
Here are everything you need to consider when choosing a home theatre amplifier:
- Give attention to the connections and make sure that you can connect to every device that you have now.
- Find the right amount of power for your space because the power difference is irrelevant and the most overrated specification in the world of audio.
- Decide whether you need wired or wireless system
- Before buying check whether the device will work with your TV
Things to Consider When Buying the Best Budget Stereo Amplifier
Getting a high-end amplifier is no joke and could be an annoying task when you don’t have the proper knowledge of the fine points of an amplifier. With that in mind, you need a perfect round-up done by the professional experts – a detailed review that could help you in buying the sound gear you’re after.
That’s why we collected the specifications that you must look for in a good amplifier at the time of buying. Let’s see what they are:
What’s the output of your amplifier? How much power does it produce (as an output)?
This is very important because you don’t want to purchase an amplifier with the output of 50W when, in fact, your job is to get a 100W amp. The higher the output, the better and loud the sound will get.
The power increases with different amp models, and so do the price range. However, you could get the “steal” if you do the proper research, though you don’t have to do that since we have already done that for you.
Is your amp BT-enabled. BT stands for Bluetooth. This needs to be looked at if you’re trying to invest in a wireless amplifier.
It is okay to get a wired amp, but if your requirements say just the opposite, why not get a wireless amp?
We’ve listed many BT-enabled amps above, go with the one that meets your needs.
With how many devices can your amp be connected through different mediums? Does it have features like AUX, USB, and RCA?
As far as buying one of the best budget stereo amplifiers in 2020 is concerned, you should at least invest in an amp that brings these functions to the table you could get the most out of it.
Of course, it is.
How can you skip this one?
Since your job is to find one of the best budget stereo amplifiers this year, one thing you must be aware of very well is how much your amplifier costs.
That’s because you don’t want to break the bank, do you?
Of course, you won’t. That’s why you’d opt for the “best cheap stereo amplifier in 2020”.
5. Weight and Portability
If you tend to replace your speakers along with the amp from one place to another on a regular basis, you have got to ensure that you’re purchasing a lightweight amp.
You’d be surprised to know that there are amps that can even fit in the palm of your hand and the good news is that we’ve listed them above in this article.
So, these are the basic things that make a huge difference. We know there’s not much of it you can get as compared to the features you get in the pro audiophile amps, but considering the pricing model, this is perfect.
Best Budget Stereo Amplifier: Conclusion
So, that was it – a detailed review of the cheap mini amps available on the market in 2020. There’s no doubt that you can also high-end amps, but the whole purpose of this buyer’s guide was to conclude the best budget amps, not the expensive ones.
Anyway, this is the ultimate list and we tried our best to keep it as reasonable as possible because we know that people can’t afford to buy the luxurious amps and that’s why they end up searching for the cheap amps (i.e. best budget ones) so they could get started with no pain in the neck.
