It will be difficult to purchase the stereo equipment that you don’t have any conception and knowledge related to them. You really believe in the manufacturers, the brands, or the salesman? You think that they will tell you everything that you’d like to know, right?
Right now, we will take a specific example – the amps. Yes, you actually know all the notions about the amps, don’t you? And, what is its mean? The majority of the people think that the meaning of the amps is the expression for a long period of time. It regrets that not many people know the practical definition. Saying to the sound, it must mention to three types of the power – the music power, peak power, and RMS power.
People use the specs in order to measure the consumer electronics. Nevertheless, when choosing to purchase the stereo equipment, it is a considered-able idea before picking up one. It can say that we are lucky when living in a technological era, so it is difficult to purchase a bad model unless you buy one too cheap. Therefore, this one isn’t worth to worry. The most common issue for the poor-quality one is the connection.
Saying to this one, we’d like to give the guidelines for the consumers, who can confuse with the meaningless items when choosing to buy an excellent model for their own home theater system.
What You Need to Know about the Home Theater Audio System
Pick up an Amplifier
To own an excellent amplifier, it ought to be heavy. There doesn’t have to be heavy on the scale that is in deliverance. It means that a high-current amp is good in comparison with one that hasn’t owned. Frequently, at the power-given rating, it will provide a lot of crispier stereos. These sounds aren’t distorted until you use at the maximum level. Taking an instance is a 500-watt amplifier with the high current is appreciated higher than a 500-watt one with the regular current. Perhaps, it is not necessary to tell you that the majority of the famous manufacturers has released the high-end amplifiers/ receivers.
What Are the Power Ratings?
Do you know how to compare the RMS, music, and peak in Watts? Well, now, we will start with the RMS power. RMS – Root Mean Square is considered as the most conservative one of rating. We will explain further so that you can understand. Importantly, the equipment will be indicated the RMS power because the manufacturers want to show their quality. Yes, in many previous years, my relatives and I bought Marantz owing to its RMS ~ 20RMS/ channel. So far, it is still a great amplifier.
Looking at here, to make a comparison, you ought to find an 8-ohm load or reading and avoid purchasing any less. In case you see any manufacturers that are only quotes in their specs or only the peak power without the RMS rating, it will be weary. What’s more, you should also avoid the items, coming with the word – “music power”.
Let’s remember that the RMS is just half the peak power. The PMPO – Peak Music Power Output is often used by the salesmen. They try to sell you the speakers with the small wattage, the 100-watt speakers, for example. So, let’s avoid these speakers! According to the IT knowledge, you multiply the voltage and amps – the result will be wattage. Accordingly, the number of the RMS you need each of the channels from the amplifier yours that will depend on the speakers yours.
Do You Want the Sound of Speakers Like Their Speaking to You?
Thanks to dB SPL – Decibel Sound Pressure Level, we can rate the speaker sensitivity, at 1m ~ 3.3 feet of the distance, and 1 watt of the power. It also means that the speaker will become louder once the number is higher. What the dictated power you need from the amp for your listening purpose is this. Actually, once you increase the double wattage, 3db are added to the loudness of your speaker.
Taking an example, if a speaker rated at the 90dB sensitivity is fed up 2 watts, the loudness will be 92dB. Similarly, it is fed 4 watts – you will get 94dB loud when you hear at the 3.3feet distance. The factor in the drop-off loudness at a 10-feet distance ~ 10dB – there is a reason why we say that one watt is a lot of loud. Another instance is that a 250-watt home theater amp has an output ~ 101dB. A 500-watt amp will be 104dB.
As a whole, the best is to get a powerful amplifier compared to the maximum rating of the speaker. Do you know the reason? Because it is not powerful enough to make the speakers blow. In other words, you need an amplifier more power than your need. For example – your speaker with rating ~ 80watt, your amplifier ought to be the 100watt RMS/ channel. It recommends that you avoid using the larger number because it can affect the blowing of your speaker.
For the time being, we will learn about hertz. It is the response of the frequency. Exactly, it is the capacity of replicating the audio at the various frequencies. In general, it consists of a maximum and minimum value in hertz, along with the -/+dB of rating.
In a case of the rated frequency ~ 50 – 20,000Hz -/+ 3 dB, this one means that your speaker gets 3dB of loud with the frequencies from 50-20,000Hz. It is important that is the -/+dB rating. If there doesn’t have it, you will not likely hear anything. For the dB rating, it is as small as possible. A 50Hz speaker will be more expensive than a 65Hz speaker though these two speakers get 20,000Hz.
At present, you are a professional one in learning about the audio operation. Certainly, now, no salesmen can fool you when choosing to buy the stereo equipment. After arming this knowledge, you can be confident to purchase online without needing to worry about any problems. All in all, you must remember that the RMS output of your amplifier forces stronger than the speaker, but it isn’t too much.
