IQVDA00-01 Analog Video DA with Control

The IQVDA00/01 provides up to 14 equalized analog video outputs. Features include: adjustable gain and equalization, full remote control and status reporting. Sync and burst level warnings provided are for low-level signals. Its 35 MHz bandwidth allows it to be used with HD component signals.

FEATURES

  • Up to 14 high-quality outputs
  • Balanced loop-through input
  • Terminating input option on single width rear panel allows extra output
  • 35 MHz bandwidth
  • Adjustable gain and equalization
  • Equalization for RG59U/Belden 8263 or PSF1/2/Belden 8281 (link selectable)
  • Full RollCall remote control and signal identification
  • Sync and burst level warnings
  • Automatic gain control (AGC) with respect to sync height
  • Automatic equalization (ACC) with respect to burst height
