1:3 Component Video, S/PDIF & Stereo Audio Distribution Amplifier


The VM-30CA is a high-performance distribution amplifier for component video (YUV), S/PDIF and unbalanced stereo audio signals. It takes one input of each signal type, provides correct buffering and isolation, and distributes the signal to three identical outputs.

Features & Benefits

  • Bandwidth - 400MHz (-3dB).
  • HDTV Compatible.
  • Level (Gain) & EQ (Peaking) Controls - Individual controls for each of the component/HDTV video signals (Y, Pb, Pr).
  • Level (Gain) Controls - Left & right for unbalanced stereo audio.
