engineers would assert that a microphone preamp affects the sound quality of a
recording just as much as the microphone itself. Different combinations of
microphones and preamps can achieve a wide range of tone, character and mood.
Microphone preamps come in many shapes and sizes, and vary greatly in price from
a few dollars to many thousands of dollars. Many mixing boards or desks have
microphone preamps built in. There are also a plethora of external preamps from
which to choose, which is great for adding the exact tone and feature set one
needs for setup.
Some preamps exist as one part of a channel strip, which can include other kinds
of audio recording devices such as compressors, equalization (EQ), noise gates,
in our daily need that can be easily by implement a simple applied technology.
So our life become easy and comfort. We can make anything work automatic, or
work without our intervention so if we forget to run it, or to turn off it, they
will be done by their shelf.
By a simple
applied technology, such as electronics, we can solve many simple problem as
mentioned above. With the small dimension of electronic component and small
power too, we can realize our need, such as automatic lamp, remote controller,
water tank level controller.
that mention above, we can make many device that valuable to our need, such as
decorative lamp, amplifier, detector etc. The simple applied electronic circuits
are divided in to two groups, analog and digital circuitry.
electronic circuits are those in which signals may vary continuously with time
to correspond to the information being represented. Electronic equipment like
voltage amplifiers, power amplifiers, tuning circuits, radios, and televisions
are largely analog (with the exception of their control sections, which may be
digital, especially in modern units).
electronic circuits, electric signals take on discrete values, which are not
dependent upon time, to represent logical and numeric values. These values
represent the information that is being processed. The transistor is one of the
primary components used in discrete circuits, and combinations of these can be
used to create logic gates. These logic gates may then be used in combination to
create a desired output from an input. In this page you can find one of the
