5 Things to Look For When Buying A Digital Amplifier.
A digital amplifier is an electronic device used to step up any audio producing device by converting the weak signal to a strong signal for quality sound. A good amplifier is an investment that when correctly managed could serve you for a long time and therefore shopping for one should be done carefully and critically. Below are some of the specifications you should consider when purchasing an amplifier:
1. The amplifiers power output.
A good powerful amplifier is judged by how loud it produces the sound and if it's of good quality. The power output should be high enough to meet your specific need, for example, 10 watts is high enough for your household and your car whereas 100 watts will turn up the club and rock your party. Consider the sensitivity of your speakers when buying an amplifier because too much gain on the master volume will cost you extra by damaging your speakers.
2. The inputs and connections.
Depending on your ohm load, the inputs wiring and connections should be stable. Oxygen-free copper wiring is the best conductor for your wire connections as they carry the required current with low resistance. It is also advisable to buy an aluminum coated amplifier as they conduct away the heat in case of overheating. if you have a lot of connections, it means you should choose an amplifier that has more channels and, that are preferably controlled differently to produce the best quality sound.
3. Amplifiers Crosstalk.
This is the ability of the amplifier to separate the left signal from the right output. A good amplifier should be able to avoid the coupling effect and separate the channels to produce a crystal clear sound on the left speaker and a clean play of the instruments on the right speaker. The crosstalk is measured in decibel, the higher the minus of the DB level the better the sound from the amplifier.
4. The signal to noise ratio of the amplifier.
All electronic devices have a hissing sound when connected to the power caused by the buzzing of the electrons. The sound is similar to that of the car's radiator and if it is uncontrolled, it destroys the sound quality. A good amplifier has a high sound to noise ratio to tune down the background noise to minimal unperceivable levels.
5. The percentage of the total harmonic distortion level.
This is how much the amplifier's output is changed or altered. High percentages on the distortion level destroy the quality of the sound. The harmonic distortion percentage should be below 1% for an awesome quality output. With low percentage, it would be like listening to an original live recording.
Buying the right digital amplifier could be challenging processes especially with a lot of varieties to choose from and fraudsters who would want to take advantage of you, by selling you an amplifier not worth your money. It would be therefore wise to shop and get advice from known professionals with verified credentials such as the specialist from a caraudiologic company who are great dealers of good genuine amplifiers.
