Audio/Video Mixer

Description
Audio/Video Mixer so-called VMX-1104 is a stand alone type of Audio and Video Mixer that mainly use in a small scale broadcasting system such as churches or school studios. It offers various image effects and audio/video transitions with a high picture quality and a high sound quality.


  • 4 channels A/V input, 6 channels A/V output: Composite video, S-Video, Component video, RGB, Unbalanced audio, headphone
  • Operator Screen- Convenient and intuitional GUI like a PC: SXGA(1280x1024) resolution, support 256 colors, Support PS/2 Mouse 
  • 22 Effects: Brightness, Contrast, Hue, Saturation, Black&White, Sepia, Binary, Negative, Posterize, Mirror, Half Mirror, Flip, Half Flip, Sharpness, Blurring, Edge, Embossing, Mosaic, Diffuse, Pencil, Color Selection, Wave 
  • Useful and effective 256 transition patterns: Cut, Fade, Wipe, Edge, various Trajectories
  • Transition Direction: Forward, Reverse
  • Transition speed: 9 steps
  • Video and audio individually selection possibility
  • Color virtual channel (16 color)
  • 120 border shape appointment possibility of pattern
  • Automatic and manual transition function
