Overview
3 Overview
The VM-30AYC 1:3 Audio/s-Video DA is a high performance 1:3 distribution
amplifier for s-Video and stereo audio signals. The VM-30AYC accepts one
s-Video signal1 and/or one stereo audio signal and distributes them to 3 identical
outputs. A set of front panel trimmers lets you control the video level and the audio
level.
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VM-30AYC
away from moisture, excessive sunlight and dust
