■ APPLICATION

• This product transmits signals in TV RF frequency after demodulating digital terrestrial signals input into video and audio signals.

■ FEATURE

• It is digital terrestrial (ATSC) input channel variable and analog(NTSC) output channel variable type.

• It can transmit terrestrial adjacent channels with an all-in-one composition of digital receiver and modulator.

• It is easy to convert and check channels with application of AIR/CATV CH LED.

• It can prevent mal-operation with the addition of switch lock.
