1x2 Composite Video Distribution Amplifier, Auto Gain and EQ Control

Model: 81-123-102

  • Single-ended or differential input with AC or DC coupling and standard/75 ohm or external/loop-through termination configurations
  • All outputs are standard 75 ohm series terminated high strength drivers
  • This manual includes models, within the 81-series, that incorporate Automatic Gain, Equalization, and DC-restoration of the video signal
  • Critical in correcting the degradation that occurs in long transmission lengths
  • Units operate correctly when powered from a 12-24 VAC or 10-34 VDC power source

Product Info
Tech Specs
The 81-Series devices are Composite Distribution Amplifiers (DA’s) designed to buffer and distribute NTSC/PAL Composite Video Baseband Signal (CVBS) source to four, eight, twelve, or sixteen other devices.
  • Single-ended or differential input with AC or DC coupling and standard/75 ohm or external/loop-through termination configurations
  • All outputs are standard 75 ohm series terminated high strength drivers
  • This manual includes models, within the 81-series, that incorporate Automatic Gain, Equalization, and DC-restoration of the video signal
  • Critical in correcting the degradation that occurs in long transmission lengths
  • Units operate correctly when powered from a 12-24 VAC or 10-34 VDC power source
  • Input power source is fully isolated from video input and output signals
  • Power supply isolation is highly effective for prevention of ground loops
  • Power connector has an integrated threaded/screw flange for shock and high vibration environments
  • VAC’s proprietary encapsulation process provides additional shock, environmental and vibration protection
  • Universal Serial Bus (USB) port/interface provides the unit maintenance interface
  • Permits the user to view and change the default configuration parameters, select specific inputs for system debug, and upgrade firmware
  • Internal non-volatile memory is used to hold the power up default settings
