The VM-312 is a distribution amplifier for
multi-format video: composite, s-Video (Y/C), and component (HDTV) signals, each
with unbalanced stereo audio. The unit takes one video/audio input of each
format and distributes it to two identical outputs.
Features:
• High Bandwidth - Composite: 490MHz (−3dB), s−Video (Y): 420MHz (−3dB) &
Component: 450MHz (−3dB).
• HDTV Compatible - Component input.
• Desktop Size - Compact size. 2 units can be rack mounted side−by−side in a 1U
rack space with the optional RK−1 adapter.
Applications:
• Multi-format presentation applications that require a preview option.
• Stage and educational applications.
• Video studios that need multi-format signal distribution. |
