An amplifier is an instrument of music that
is used to increase or change the amplitude of a signal.
The amplifier is uses wildly.
In audio systems, amplifiers use
loudspeakers to make human voice louder. Amplifiers also can be classified by the
amplification system of using. Transducer is a device that converts a signal to
another. This can be called in other terms such as transformer or sensor.
There are many types of amplifiers namely
electronic amplifiers which are used in radio, television, stereo systems etc.
The power amplifier is an electronic amplifier, as the name suggests, it is
related to the amount of power loaded or supplied. An operational amplifier
also called as op-amp is used in many instruments and for signal processing.
The best way to choose an amplifier is, to find
out how powerful it is?
First we need to know about the amount of
power.
Then, we need to decide how big it should
be, or how big you need.
The next step is to go to a shop and choose
one you like and try it that make sure it will works well.
For example, when choosing a guitaramplifier for a guitarist who has to practice by himself, the 15 to 30 Watts
will be better. A guitarist who plays in a band needs at least 60 to 75 Watts
of power. And then is to finish the question how large it should be? Generally
amplifiers are categorized into two configurations namely Combo and Stacks. A
combo amp is a combination of an amplifier and a speaker which is compact and
portable. A stack amp is used to choose which works better. The stacks are
classified into two types namely half stack and full stacks. In the former, a
speaker cabinet combines with a head and in the latter, two speaker cabinets
are used.
The third step is to research on what all
features an amplifier should have. Some amplifiers come with digital effects
built in.
The fourth step is to bring your guitar to
the shop and choose appropriate amplifier which best suits your guitar. The
need to bring your guitar is to ensure that the sound is clear and it fits all
our features. The last but not least is to allot the budget.
