NMX-ATC-N4321-C 音频收发器卡

IP 音频收发器卡

NMX-ATC-N4321 音频收发器是一款 IP 音频解决方案,可通过 IP 发送和接收双声道平衡或非平衡音频。只需将平衡音频输入连接至输入端口便可转换为可像数据或声音一样切换和传送的 IP 数据包。平衡音频输出接收 IP 音频流并进行解码模拟,同时保持较高的音频保真度。NMX-ATC-N4321 完美适用于点对点或点对多点音频传输,利用与 SVSI 联网音视视频切换与馈送解决方案相同的控制选项实现音频矩阵切换和馈送。

各装置可通过两个自感应千兆以太网端口以堆栈方式利用家庭网络或物理独立网络传输低延迟多声道音频。每个以太网端口就是一个 POE,与 POE 开关配合使用,无需借助外部电源。NMX-ATC-N4321 可构建含任意数量输入和输出的音频矩阵。由于音频控制机制与 SVSI 的 IP 视频矩阵完全相同,因此视频和音频矩阵可利用相同的控制器进行组合布设,最终实现数字媒体馈送。
