The VDA-108 is a 1 input, 8 output video distribution amplifier.
Gain and equalization are adjustable, and the controls are accessible from the front of the unit. The video input is looping. All input and output connections are made via BNC type connectors.
The RS-41V is a 4 input, 1 output video routing switcher, with dual outputs.
Input selections may be made using the front panel switches, or remotely, using simple switch or relay closures via the rear panel remote connector.
All video inputs and outputs use BNC connectors. The output gain and frequency response are internally adjustable. All switching occurs during the vertical interval of the output video.
When coupled with the RS-41A, a complete 4x1 video/stereo audio dubbing/routing system is obtained, complete with breakaway.
