Acoustics instruments

3.  An amplifier boosts the audio
signal and produces a more
powerful version of it.
 Amplifiers are found in several
devices such as microphones, cd
players, television etc.

5.  A guitar amplifier is
designed to amplify
the electrical signal of
an electric or acoustic
guitar so that it will
produce a sound
through a
loudspeaker that is
loud enough for the
performer and
audience to hear.

6.  Bass amplifiers are
designed for bass
guitars or more rarely,
for upright bass.
 They differ from
amplifiers for the
regular electric guitar
in several respects.

7.  A keyboard amplifier, used
for the stage piano,
synthesizer, clone wheel
organs and similar
instruments, is distinct
from other types of
amplification systems due
to the particular challenges
associated with keyboards;
namely, to provide solid
low-frequency sound
reproduction and crisp
high-frequency sound
reproduction.

8.  The price range of guitar amplifiers range from
Rs. 1,500.00-Rs. 9,730.00.
 The price range of bass amplifiers range from
Rs. 2,000.00-Rs. 14,515.00.
 The price range of keyboard amplifiers range
from Rs. 1,500.00-Rs. 23,100.00.

10.  A speaker is an electro acoustic transducer that
produces sound in response to an
electrical audio signal input.
 A speaker is essentially the final translation
machine -- the reverse of the microphone. It
takes the electrical signal and translates it back
into physical vibrations.

11.  The price range of
mini speakers range
from Rs. 141.00-
Rs. 245.00.
 The price range of hi-
fi audio speakers
range from
Rs. 1000.00-
Rs. 10,000.00.

13.  A microphone, colloquially nicknamed mic or
mike.
 It is an acoustic-to-electric transducer or sensor
that converts sound into an electrical signal.

14.  The price range of
microphones range
from Rs. 540.00-
Rs. 3,160.00.
