DVA 5718 L
1 to 8 Analog Video/Sync Distribution Amplifier
The D VA 5718 L is a flexible and cost effective solution for high quality SD and HD analog video or sync distribution. The module is a single channel 1>8 analog distribution amplifier with a passive loop through input. This module is ideally suited for demanding high quality broadcast and professional video applications.
Digitally adjustable video gain and equalization is provided for system calibration with input signal presence detection for SD or HD video. Inputs can be AC or DC differential coupled with or without input clamping (selected via control system)
The module can also function as a Sync DA, handling both tri-level HDTV sync or bi-level SDTV sync inputs.
Microprocessor control and on board flash ram enable configurations and settings to be stored within the module (through power cycles and module removal).
Local control capability is provided via the integrated dip switches. Remote control, status monitoring and error reporting is possible when using the LYNX Centraal control system.
