How To Calculate Amplifier Power Gain

Having TV antennas

Music would probably be one of the most helpful things in life. Its effect cuts across time and age. In the advent of new technology, playing music has become sophisticated as well. Parties will never be complete without devices that will amplify the latest music in town or the voice of the master of ceremonies. Thanks to advanced technology, subwoofer amplifiers have become a mainstay to our parties, social events or in simply enjoying the play list in our MP3s. Amplifiers are not only for music. Generally speaking, an amplifier is a device that increases the amplitude of a signal in any given device, whether a CD player or a DVD player. But have you ever wondered how an amplifier power gain is calculated when you’re tuning it with your head unit in order to produce the sound you want? Here is how to do it.

  1. Determine the maximum output of your source. The first thing that you have to do is determine the maximum peak of your song. You can do this by listening to the song and then manually locate its highest peak. This is important because your source will dictate the set up of the amplifier. Remember that an amplifier is used to increase the signal that it receives from the source. To do this efficiently, the signal sent should be compatible with the gains of the amplifier, otherwise it will result to distortion. Also, you will need this in determining the stereo power you need.
  2. Determine the average level. After determining the maximum peak of the song, it’s time to determine its average peak. Again, you will have to do this manually, the same way you determined the maximum output of your source. This will also be necessary in setting the amplifier power gain.
  3. Adjust the amplifier through ear. Now that you already know the maximum and average output of your source, it’s time for you to set the amplifier. Remember your goal here is to balance the signal sent with the gains of your amplifier power. Everything you need here is your ear. Start setting your amplifier to some points lower from the average capacity of the source. Increase it slowly, up until you hear the sound distorting. This has something to do with the amplifier circuit. The signal sent is no longer balance with the gains you set your amplifier. The gain should just be equal to the signal sent to your amplifier. Balancing the gain and the average output does not mean that you’ll not hear distortions again. Remember that your song has a maximum peak. And when it reaches that maximum peak, distortion may occur again. The only way to decrease this hissing is to use a higher-class powered amplifier. It will all depend on the consumption you need and of your preference. Never forget to use an amplifier transformer when needed.

Amplifiers gave our parties and social events life. Over the years, even this technology has evolved. Different amplifier designs have infiltrated the market. Now, we can fully enjoy our MP3’s without disturbing out neighbors. We can close our world from other people by just piercing earphones tight and turning on our play list. We might not see much importance from knowing how to calculate an amplifier power gain. But on the practical side, knowing it will help us enjoy our music to its highest potential since through this, we can adjust the mixture that really suits our tastes.
