휴톤의 최신 3CH. D to A Modulator는 ATSC(8VSB) 표준 규격의 국내 디지털 지상파 신호를 수신하여 아날로그 NTSC로 변환하여 송출하여 주는 장비입니다. HDA-3000은 안테나에서 수신된 국내 디지털 지상파 신호 3채널을 동시에 Demodulation하여 아날로그 규격인 NTSC로 변조하여 3채널의 RF로 각 각 송출하여 주며 1RU 크기로서 기존 Rack 공간의 활용도를 극대화 시키며, DTV로 전환하지 못한 세대를 위한 공청용 장비입니다. 또한 Green Mode를 적용하여 방송이 중단 시 Sleep Mode로 전환하여 절전 효과를 가질 수 있는 장비입니다.
