The X-1201 supporting 3G/HD/SD SDI signals, is a twelve input routing switcher that provides a convenient, low cost way to route high definition and standard definition serial digital signals. The X-1201 routers are used for 3GB/s, 1.5GB/s, 270MB/s, 360MB/s, 540MB/s and DVB-ASI serial digital signals. When the unit is ordered with the Quad 12x1 AES router option the AES output busses can be used in an "audio follow video" mode, or can be broken away from the video bus. This router features the ability for redundancy protection with a bypass relay and optional dual power supplies. The router electronics are housed in a 1RU rack mount frame and is controlled from the built-in front panel controls. Each model can also be purchased with an optional rack mount remote control panel that replaces the built-in control panel, or can be used as a second control panel. All units can also be controlled by Quartz over Ethernet, contact closures on the GPI control port or through the RS-232 or RS-422 serial remote control port using industry standard switcher protocols.
