The DLC-1 Distributed Learning Controller is used to control the direction of tranmission for Audio and Video signals in Distance Learning and Distributed Learning Networks. The unit receives base-band audio and video from both local and remote sites, then switches the audio and video from the site with active audio to both remote and local sites. The site that has active audio on it will be distributed to both remote and local sites. This video follows audio switching is done automatically.
The instructors audio and video will appear at both local and remote sites when the instructors audio is active. When the students audio is active their audio and video will appear at both local and remote sites. If both the instructor and student are trying to talk at the same time (both audio sources active in conflict), then the audio video switch will remain at its current postion until the selected audio source goes silent. This enhaces normal conversational switching. Both classroom and instructor will be able to see and hear the person speaking automatically.
A local TTL input is avialable to manually switch the unit to remote postition (instructor site) “receive only” if an audio conflict cannot be resolved or if the local site wants to lock out, Limit or control interruptions from a student at a local site. This feature will prevent a local problem from disrupting a Distributed Learning session.
