Lectrosonics VS1 - Manual (Page 2)

INTRODUCTION
The VS1 Video Switcher Interface is a microprocessor-based controller used between an automatic microphone
mixer and a video switcher. The VS1 provides sophisticated capabilities to synchronize video recording (with up to
8 video cameras) to the audio being recorded, using the logic output capability of an automatic mixer. Typical
applications for the VS1 are in audio/video teleconferencing, courtroom video recording, and security applications.
The VS1 is fully programmable from front panel controls, and may be quickly and simply set up for optimum
performance in a variety of applications. Input and output connections are standard screw type terminal strips for
ease of installation. The Auto-Sync capability of the VS1 allows camera switching during the vertical retrace
interval for video systems which are synchronized to an external timebase. This eliminates any rolling or other
video anomalies as different cameras are activated.
