3 Overview
The VS-401YC is a 4x1 switcher and distribution amplifier for s-Video and
stereo audio signals, that lets you switch and distribute any of the four inputs
to two identical outputs.
In particular, the VS-401YC:
Features video input and output signals on 4p connectors and audio input
and output signals on RCA connectors
Has four selector buttons for selecting the input to switch to the two
identical outputs
Lets you disconnect the input1 from the outputs by pressing a selected
button a second time
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 VS-401YC
away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 Except for the sync signal on input 1, resulting in a black screen display
