Here are some of the main specs of stereo speakers which will help you understand the quality of the amp.
Power Rating : The measurement of power takes place in Watts. But with the audio speakers, the power means a lot more, an amp's power rating says for example 90 W/Ch RMS 8 Ohms 0.07% THD, 20Hz-20kHz. And this rating indicates that the amp can deliver 90 watts of average power for a channel in the speaker load of 8 Ohm with a maximum of 0.07% of total distortion of harmonic for the specified range of frequency.
The format of power specification was the contribution of the “US Federal Trade Commission” which is the standard format to represent the power specification of any amp. And it is an easy way to compare the amplifiers from the many available brands. It provides all the info that we need to know while getting an amp. Speakers with high power rating are capable of delivering better performance.
Sound Quality : Sound quality is the factor which directly relates to the output of the amplifiers. The amps’ real power rating is an important parameter but what enables you to get the perfect loudness you desire is what defines the sound quality of the amp. And the sound quality is a major factor since one wants better sound, not more sound. One can enjoy the 60 W amplifier with higher sound quality than the amp with 100 W power with the bad quality of sound.
The power of the amp does not define the sound quality so don’t get the amp with high power rating check for the other specs which defines the sound quality as well.
The THD (Total Harmonic Distortion) or distortion of the audio amplifiers are the major parameters which denote the high quality of the amp. The other factors indicating the sound quality includes the S/N level or the signal to noise ratio represented in dB. Some amps specs also add the dynamic headroom as an indicator of sound quality. The amp with high values of THD and S/N level produce good quality sound. And the one with insufficient headroom cannot deliver the sounds’ high accurately.
Distortion Level : As the name suggests, distortion levels will indicate the amount measurement of the distortions in the amplifiers’ output concerning the input applied. The one with distortion levels less than 1% are not significant. And it is the same with the amplifier with a rating of 0.05% or 0.01% of THD. Also, remember that the amp with high distortion level such as 10% is not capable of delivering sound at high quality.
The Level Of Noise : The ratio known as the signal to noise ratio gives the measure of the amplitude of the level of the audio signal concerning the noise present in the background. It means that the amp with a large value of the ratio will be able to work better even with all the noise present in the environment.
The background noise in the system can be due to the hum pickup, electrical noise due to movement of electrons present in the electronic system of the amp, and AC supply noise.The amp with 90dB S/N ratio has an excellent rate. When you have an amp with high S/N value, the amp will be able to eliminate the effects of noise even at high volume. But in the case of the ones with low S/N ratio, the noise becomes noticeable at high volume.
How does Stereo Amplifier work
The primary job of amplifiers is to transform the minor electrical signals into larger ones or to amplify the signal. The amplifiers appear like some mysterious box, but there is not much mystery present.
The working principle of the box is quite simple. The amplifier just gets the signal as input from the devices such as the CD, media player, DVD, mobile phones or any other appliance. And the amplifier just generates the replica of the signal with much bigger size. And the amp uses the wall receptacle of 110 volts for the power to perform the operation.There are three primary connections in the amplifiers which are the source input, power source from wall socket of 110 volts, and the speaker output.The 110 volts power gets sent to the power supply section of the amplifier in which there is the conversion of the alternating current into the direct current.
The direct current is similar to the power from the batteries. Then the current gets supplied to the transistor which is a variable resistor. The transistor can vary the current amount according to the supply of the current. And the input signal will cause the lowering of resistance of the transistor and which in consequence allow more current to flow.The current which flows through gets set according to the signal size from the input. More current will flow in case of a significant signal which will lead to high amplification. And the frequency is the other factor which determines the amplification operation by the transistors.
And in the way, the amplification occurs in the amplifiers. There are many amplifier designs available at present but all those work in the same manner.
Best Stereo Amplifier Buying Guide and Setting Up
Searching for a good music system is difficult to a lot of extents nowadays as there is a lot of variety which is available in the market. Also, there are a lot of technical aspects which we need to consider while buying the music systems. To buy the best stereo amplifier you need to take into consideration certain requirements and also technical aspects of the same. It is not that difficult to buy a stereo amplifier if you know the right steps and procedure to buy the same. Let us look at some of the aspects which are worth considering while buying the best budget stereo amplifier.
The main aspect which you should consider while buying a stereo amplifier is the power which is required to run the same. There are a lot of amplifiers which are available in the market which comes with multiple power rating. You should always pay attention to the RMS power rating. This rating is the measure which enables you to find out how much power is put off by the amplifier. You should keep one thing in mind that the amplifier which you choose should have the power rating which is twice the power rating of the speaker. The speaker should also be overpowered rather than underpowered. The chances of damaging the speakers are more when too little power is given rather than too much power.
While looking for the best stereo integrated amplifier you must also check out the channels which are available on the amplifier. In fact, the amplifiers are characterized by the channels they provide. The majority of the stereo amplifiers which are available in the market have two channels.
The channels provide more flexibility and thus you can use it as per your convenience deciding the number of speakers which you want to use. The multichannel stereo amplifiers provide four channels. You can choose the respective amplifiers as per your convenience and also your requirement.
Stereo Mode : Stereo mode is usually the default mode for most of the stereo amplifiers which are two channeled. This mode is used for the purpose of powering two speakers one at the left and the other one at the right. In this mode, each channel receives an independent signal from the other. This mode can also be considered equivalent to the two mono amplifiers.
Parallel Mode : A signal input signal is used in the parallel mode to send the send the input channels to both the channels. This mode comes in handy when wants to use an odd number of speakers to power the stereo amplifier. This mode is used to route a mono input which can be a microphone or a mixer. The output of both the routes, however, can be delivered by through both the channels which make this mode all the more useful.
Bridged Mode : The Bridged mode is very efficient as it combines the power of both the channels. Thus there is a significant amount of power which is used to power a single output which enhances the performance. This mode is more commonly used to send signals to the subwoofer. While using the bridged mode in the stereo amplifier you must make it a point that you have followed all the instructions which are given in the instruction manual. There are many instructions which should be religiously followed to bridge a stereo amplifier.
Another most important aspect while buying a stereo amplifier is the headroom. Now for those of you are foreign to this term headroom means the extra power which you get to satisfy the RMS requirements. Having bigger headroom for your stereo amplifier allows you to play both loud as well as soft music with much ease. Headroom also helps to control the volume and keep the system clear and distortion free when the bass drops or there is a song playing on a high note. Moral of the story is that you should always check the headroom feature before buying the stereo amplifier.
Setting Up Stereo Amplifiers 2020
Cables : You must need to check the input and output options when it comes to setting up the stereo amplifiers. Power amplifiers usually offer XLR and also ¼” inputs for the incoming input audio sources. You need to check the level of the output level as well and safe side it will be better if you use separate connectors for connecting input as well as output levels as the voltage may differ and cause further problems.
The Outputs available for your stereo amplifier would be a combination of banana/binding plugs, Neutrik Speakon as well as ¼” output. The Speak On plugs adds the additional security as they provide the twist and lock connection. The banana/ binding plugs are more binding and hence can be are more versatile. They can even be connected bare if the need arises. The ¼” Output cable needs to be handled with a lot of care as these cables can sort out once they are connected to metal.
Controls : Controls of the stereo amplifier are not that hard to understand and pretty much everyone can use these controls as most of the stereo amplifiers have pretty basic controls. The typical stereo amplifier will have a gain level knob and also a signal level indicator for each channel. The colored lights are for indicating the clipping and also to signify overheating.
