다채널 파워앰프
DA-500FH
The DA-500FH is a 4-Channel Digital Power Amplifier designed for 100 V line high-impedance distribution and features lightweight, compact, high power output, and high efficiency. It delivers 500 W x 4 channels (20 Ω output) using a switching power supply. Each channel is equipped with an independent power section. It can be electrically isolated from the high-impedance speaker system by attaching the MT-251H Output Transformer (optional). Its Control/Monitor terminals permit power ON/OFF control of the individual channels and status monitoring for the power ON/OFF on each channel, protection on each channel, and fan operation. Prepare the control panel or status monitor display panel separately. It can be mounted in an EIA Standard equipment rack (2 unit size).

본 기기는 100V 라인 하이 임피던스의 EIA 표준 설비 랙(2U 크기)에 장착 가능한 가볍고 콤팩트한 고출력, 고효율이 특징인 4-채널 디지털 파워앰프 이어야 한다.
스위칭 전원으로 500W × 4 채널(20Ω 출력)을 제공해야 하며, 각 채널에는 독립된 전원부가 장착되어 있어 MT-251H 출력 트랜스포머(선택사양)를 부착함으로서, 하이 임피던스 스피커 시스템에서 전자적 절연이 가능 하다.
제어/모니터 터미널을 이용하면, 채널별 전원 ON/OFF 를 제어할 수 있고 채널별 전원 ON/OFF 상태, 채널별 보호 상태 그리고 팬 작동 상태를 모니터링 할 수 있어야 한다.
