The VM7404 4-Port 3G-SDI Input Board offers an easy way to route any 4 SDI video and audio sources to multiple displays when used in combination with an ATENModular Matrix Switch. This input board provides the capability to connect to SDI sources, including 3G-SDI, HD-SDI and SD-SDI, and supports high quality video resolutions up to 1080p @ 60 Hz. The VM7404 also supports separate analog stereo audio signals that can be routed independently. Furthermore, the board is based on a hot-swappable design, allowing the ATEN Modular Matrix Switch to remain on while the board is changed. Ideal for surveillance systems and numerous other broadcast-grade A/V applications, the VM7404 allows you to effectively centralize routing for all your 3G / HD / SD-SDI devices.
