【Yi
Miao】You
have images on TV but you only have sounds in
radio. In fact, there are still many integral
elements in radio, for example, sound effects,
records, and compact disks, etc. The CD shelves
and data room are of great importance to our
radio. On the other side is the studio, which is
equipped with acoustical boards, and rugs. Those
objects help absorb noises. There are two
microphones and machines and we will elaborate
on them later. The frequencies of Chengsheng
Radio are AM855 and AM1260. The difference of AM
and FM lies in the radio waves and how they are
transmitted. Apart from that, FM uses Mega
Hertz, whereas AM uses Kilo Hertz. AM uses
amplitude modulation, but the sounds generated
are less clean and clear, while FM produces
sounds that are good and pleasant. The
disadvantage of FM is that its signals will be
blocked by tall buildings, causing poor
reception in urban areas. AM, on the other hand,
covers a wider area than FM, as it is not only
able to transmit its signals in the air but also
underground via the networks installed beneath
the earth. We broadcast by turning sound waves
into radio waves and then sending it out. The
devices you see are all for professional use.
This machine has a name called “the forefront”.
It provides all the things you will possibly
need in recording, such as audio mixing and even
timbre adjustment. |
