这里介绍的耳机通讯装置最初是为辅助广告片摄制而设计的。导演可以通过这个通讯器与最多三个摄影师单独或同时进行双向交流,协调拍摄工作。虽然,现代通联多己无线化。但对于小单位、小规模的应用,该装置仍不失为一种价廉、实用,且可自制的通联系统。当然,这个系统还可以扩展应用,如用于演唱会、体育赛事、单位、学校传呼等场合。本装置只有三个通道,如欲扩展通道也十分简单,只要增加电路板数量和改用多档位转换开关,即可实现。接听耳机也可以使用扬声器。该系统是有线通讯方式.主控设备 The headset communication device introduced here was originally designed to assist in the commercial production.

Listen to headphones can also use the speaker. The system is a wired communication
