3G/4G/4K传送设备-Audio Report

北京安迪诺数字系统技术有限公司 2017-06-13 10:57:12

型号:Audio Report

音频的报告
 
来自背包的现场录音
有了WMT音频报告,移动视点为现场广播报道提供了专业的音频设备。
有了两个平衡的线和麦克风输入和4个连接的LTE调制解调器,WMT是你能得到的最好的低延迟音频报告使用连接3g/4g连接。
WMT是一种高质量的音频放大器和经过验证的WMT结合技术的组合。
在接收端,WMT的播放将把音频通道返回到模拟平衡的音频中。
这是所有其他WMT设备使用的相同的布局。
此外,还提供了一个带有单独音量控制的回话通道(IFB)。
