MDK-111A Lite – HD/SD SDI Mixer / Keyer

The MDK-111ALite is a high quality HD / SD SDI video keyer with A / B background inputs for additional background mixing. An excellent device for keying external devices such as character generators, graphic systems and EAS devices into a program feed. The MDK-111ALite offers full key control with shaped and unshaped keying, self key or alpha key, transparency, gain and clip control, mask and matte fill. The additional background A and B inputs allows for background dissolves and V-fades in behind the external key source.

All four inputs have line synchronization, locked to an external reference, to ease system timing requirements. Outputs for PGM, Preview, and Clean offer independent proc amp control with FTB capability.

The MDK-111ALite offers a wide range of control with a total of 8 programmable GPI inputs or tally outputs, M2100 serial control and full DashBoard Control and Monitoring.

Built in bypass relay from A input to PGM protects your air feed when the device is taken off-line to ensure critical program content is not lost.
