The DDC-2512 is a proven way to supply power to third party cameras or AV equipment. The DDC-2512 is designed to be used with the Datavideo PD-3 Power Distribution unit and CB-23 All-in-one cable.
The DDC-2512 automatically accepts input voltages between 9 and 30 V DC to provide a regulated 12V DC output. The unit can allow for 4pin XLR type input connections and has a 4pin XLR type DC output connection.
Conferences, huddle rooms and presentations are fast paced environments where time is money and the audience does not like to wait. This is where an AV converter like the DAC-75T just thrives. Your speaker wants to connect their laptop and see it displayed or projected straight away. They may have VGA, DVI, HDMI, Display Port or even SDI. So not getting the picture and fiddling with tiny dip switches, in a dark room, is what they want to avoid. Especially when there is no tech guy around.
