On the rear panel there are: outlet for AC power supply, the six dolby channel on balanced outputs by XLR connectors, the LAN port for remote control of volume, input BNC SDI A on where to send the signal SD/HD, in the case of 2K signal using the second BNC: SDI input B, on the third BNC connector are output SDI out, which is a looped output signal SDI (SD / HD) of signal input on the SDI connector A.

A HDMI connector allows you to connect a monitor to control the incoming video signal, via an adapter, you can also exit with DVI-D signal.

A USB 2.0 port is used only for programming the internal firmware by computer.

Display Requirements
Interface DVI-D connection to LCD computer monitor or HDMI Type A connection to HDMI display.
Resolution via DVI-D 1920 x 1200 or 1920 x 1080 required for HD1080 video SDI formats. 1280 x 800 recommended for HD720 video SDI formats. 2560 x 1600 required for 2K feature film formats. DVI-D displays generally do not support 720p50 or 1080p50 but most recent HDMI displays do.
Capturing from copy-protected HDMI sources The HDMI input of a display must accept either:
• 1920 x 1080 for HD1080 video SDI formats or
• 1280 x 720 for HD720 video SDI formats
A Full HD display should be considered if pixel for pixel video is desired as other HDMI displays present at a lower resolution.
Refresh Frame Rate for DVI Nominal 60Hz, however 48 to 75 Hz recommended.
