   최근 선박에서는 IT 기술 및 eNavigation 요구에 힘입어 전자 항해 통신 장비들뿐만 아니라 대부분 장비들이 데이터 통신에 의하여 상호 연동되어 운용되기를 요구하고 있으며,타 선박과 부표 및 육상과도 점차 더 많은 데이터 통신이 요구되고 있습니다. 이를 위하여 당사는 선박 장비들의 다양한 신호의 변환과 인터페이스 및 네트워크와..  +Read more

ZAI-220

The Audio interface ZAI-220 has 2 audio inputs and 2 audio output channels. Each input circuit has an independent volume control circuit and controlled between -20dB and + 40dB by 20dB step. These two volume controlled audio signals are mixed and out as one audio signal. Input signal, output signal and input power are gully DC isolated with each others.

It is very useful to match two different level audio signals and/or mix 2 audio signals into one.
