MP3 (MPEG AUDIO LAYER-3)

MP3 is one of music file formats that can contain music with stereo sound quality as good as audio CD, which is a
type of MPEG as audio, video compression standards. Compression rate is 1Mb by 1 minute and thus about 3~ 5
minutes are sufficient if recording songs of 3~ 5 min or so. Differently from audio CD, a music file made of MP3
can contain over 130 songs for popular songs or folk songs and playing time is also about 10 hours. MP3 clears
frequency range for a human being not to discernable and so has advantage to compact it to 1/12 or so while
maintaining music as sound quality equivalent to CD level. For example, deriving a song in a music CD while
maintaining music as sound quality equivalent to CD level becomes capacity of 50MB or so but if compressing and
converting it to a MP3, size of the MP3 largely reduces to 4~5MB.

- WMA (WINDOWS MEDIA AUDIO)

WMA is a multimedia compression method developed by Microsoft Corporation and is technology to compress
only music from 'Window Media Technologies', and provides same sound quality as format of MP3 up to
128Kbps, which has lower 64Kbps format than MP3.
In other words, it has a file size of the half of the MP3 and provides same sound quality as MP3.

- DIGITAL OUTPUT AND STANDARDS

Audio signal of a CD records digitalized signal. Usually digital audio signals are converted to analog signals with
a Digital Analog Converter (DAC) within a player. On the other hand, electrical digital signal is replaced with
optical signal by coaxial cables, semiconductor laser or light emitting diode (LED), etc and can be connected the
other devices with optical fiber cables. The unit receiving optical signal converts optical signals to electrical signals
again for various processes. Transmitting digital data as they are is less affected less by electrical noise than
electrical signals, and thus less data error occurs.
The digital interface used in this product is a form of S/PDIF (Sony/Philips/Digital/Interface) and complies with
standards called as IEC958.

- AMX, CRESTRON INTERFACE

Operation specifications that can be pin-out or controlled by a control port for customary integration for a remote
control unit such as AMX and CRESTRON control system are as follows:

1. RS-232 PINOUT Spec

Application of The Antenna

Application of The Antenna

- FM RECEIVING ANTENNA

The electric wave of FM broadcasting is weakening in hills and valleys, around buildings and in iron­reinforced buildings.

- INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM

Listening to the broadcasting, fix the antenna after deciding the location and the direction so that the reception
may be optimized.

- INSTALLATION OF ANTENNA USING THE COAXIAL CABLE

Noisy reception may occur in built-up areas and factory sites as well as around power cables. This may be the case
even when an antenna is used exclusively for FM. In these regions, install the antenna using 75Ω coaxial cable.

- INDOOR ANTENNA

In the regions where FM broadcasting is heard comparatively well due to the near distance to the station or
wooden structure, you can receive broadcasting of good quality by using T-type antenna.

- AM LEAD ANTENNA

Fix one end of a six to eight metre length of vinyl-coated single cable to the AM terminal and the other end to
a high place like a wall.

- AM OUTDOOR ANTENNA

Install the vinyl-coated cable to an outdoor place if the AM reception is not good enough.
