With the RMC-200 it's easy to control a camcorder from a tripod arm. Zoom, record and pause without having to touch (and shake) the camera itself. At such as low cost, it's a wonderful way to transform camera equipment for studio use.
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.
