  • DSK-3901
    3G/HD/SD Downstream Keyer

    The Densité DSK-3901 is a low cost, modular downstream keyer, with two independent pairs of fill and key inputs. This 3G/HD/SD keyer is ideal for inserting two external character generator feeds over program video. Up to 10 channels of keying can be housed in a single 3 RU Densité 3 frame. An integrated audio mixer provides eight channel voiceovers, as well as audio clip storage and playout. Background audio is automatically ducked during voiceovers. Audio can be accepted as embedded audio or as four external AES inputs. The audio mixer features separate processing for the program and the preview chains.
