What Are Some Of The Most Important Features Your Stereo Amplifier Should Have?


Some of the most important features to have on your stereo amplifier would be good input connections, a good signal to noise ratio, lots of power, and total harmonic distortion to measure how much the amp affects the sound output. 

Good input connections mean that you have a wide range of inputs to make sure you can connect everything you want to connect. You want to have enough inputs to be able to connect iPods and whatever else. 


The power outage is basically telling you how much power you can pump out or how loud your sound can go. If you want loud music, you need to have a good power outage. The signal to noise ratio or SNR is the background noise that everyone hears and can’t avoid. With total harmonic distortion, this makes sure that you hear as much of the music and sound as possible without noises coming from inside the equipment. 


How Long Do Stereo Amplifiers Last? 


Stereo Amplifiers are designed to last the test of time, which also depends on how often you use it. They are built to last between 10-20 years, and many people who have them can agree with this number. 


It really depends on how you treat your stereo amplifier and how often you are using it. If you take good care of it, it should last you for many more years than that.

Do Stereo Amplifiers Sound Different? 


Whether or not stereo amplifiers sound different is based on the person. Some people believe that all amplifiers are different and you can tell the difference between the sound. Then there are other people who cannot tell the difference. 


Again, one with more power will be louder, therefore in comparing loudness; you will notice that one might be louder and more clear than the other. 


Will A Stereo Amplifier Actually Make A Difference? 


The simple answer is yes, a stereo amplifier will make a huge difference in the sound of your home theatre. If your sound is not that great, try adding a good stereo amplifier and you will immediately recognize the difference. Poor sound is not fun when you are trying to watch a thrilling movie or listen to a good song.

How Do You Repair A Stereo Amplifier? 


First things first, you do not want to listen to a stereo amplifier that is not working in full force. If for some reason you need to repair your amplifier, I would recommend checking all the connections to make sure a cord didn’t disconnect. Also, take a look at the fuse and make sure you didn’t blow a fuse. 


This could prevent your stereo amplifier from not working properly. If your cable is dirty, this can prevent your amplifier from passing the electricity between the cables. Try cleaning the jacks to make sure this is not the issue. Make sure the amplifier is not plugged into the socket while you are cleaning the jacks. 


After you are done dusting it, plug it back in and give it another go. Check the ends of the cords for any damage. If you notice damage or fraying with a cord, you will want to replace that cord. 


Do Stereo Amplifiers Need Cleaning? 


Just like any other piece of equipment, you will need to disassemble the stereo amplifier and preamp in order to do a deep cleaning of your amp. 


Cleaning your stereo amplifier will allow you to figure out issues you might never have thought you had. This will keep your stereo amplifier in good working condition for many years. Remember, what you put into it, you get out of it. Treat your amplifier with love and care so that it will last you a long time. 


How do you set up a Stereo Amplifier? 


Most, if not all, Stereo Amplifiers come with instructions on how to set them up. If not you will want to make sure none of the cables are connected to electricity. First off, connect the two different plugs on the one side of the audio cable to the right and left outputs for the tape deck, which is on the home stereo. Connect the red plug to the right and the white plug to the left. 


By following the instructions above or the instructions that come with your stereo amplifier and watching some videos like this one,  you’ll be able to easily set up and connect your amplifier in no time.
