Digital audio-visual system (1):
This is the first instalment of an article that describes a highend slide control system based on a Centronics-driven dissolve unit for four slide projectors. The system allows up to 16 projectors to be controlled automatically or by hand. Music or comment to accompany the slides can be synchronized with the aid of an advanced pulse or timecode registration unit. The timecode option enables you to record all control actions in a complete slide show, whereby all relevant data are safely stored, along with the parallel sound track.
