If you are a recording artist and have an acute passion
for music, you will invest in the right equipment to produce the best music
which will charm your senses. There are a number of music accessories you will
need in your studio to get your job done. Among them are audio amplifiers and
stereo amplifiers.
What is
it?
An amplifier is an electronic equipment which controls the
voltage, power and amplitude of a signal. Mostly used for wireless
communication and broadcasting and in various audio equipment, amplifiers
enhance the sound output and lessen the distortion of sound.
Types
of Amplifiers
Amplifiers come in different shapes and sizes according to
the purpose they are used for. If you want to buy power amplifiers online, you
will find that they are available in a range of watts and can handle different
frequencies. Amplifiers can be as small as those used for hearing aids and can
be big for supporting huge sound boxes for concerts and festivals. They work in
both analog and digital circuits and can be used alone or in a sequence with
other amplifiers. Let’s learn some of the factors which influence the buying of
amplifiers. C
1. Voltage/current/power: Amplifiers are classified on the basis
of current, voltage and power. In a voltage amplifier, the output voltage is
higher than the input voltage whereas if you buy power amplifier online, you
will find that the output power is greater than the input power.
2. Frequency: Amplifiers boost not only a stable signal but also
a fluctuating one. Audio and video signals differ in frequency and their
fluctuations vary by mammoth margins. Audio and radio signals fluctuate the
most because they have a broader frequency range. Video signals cover a wide
range of frequencies. Amplifiers are designed to handle various frequencies.
But that doesn’t mean that an amplifier meant to boost audio signals will work
effectively with radio and video signals.
