录制消息管理器

Summary & Images Specs Downloads & Support

DMM 4650是数字音频存储系统,能录音和回放,也能生成报警等音频信号。它的主要用途是作为ProAnnounce系统的附加录音设备,但也可以独立使用。音频信号可以包含报警、警锣、消息,也可以是这些内容的任意组合。这些程序通过Dynacord创建并存储为预设值。

消息的音频质量可以根据内存扩展及不同用户需求进行选择。使用最大内存扩展时,共可录制16分钟的音频。提供密码保护功能。操作简单,类似录音机或CD播放器。通过计算机界面,可保存并装入单元配置和消息数据。

为了确保功能可靠性,可安装自我检测和音频数据验证功能。报警通过专用输出端提供。DMM 4650采用闪存,因此无需维护。
