Overview

3 Overview
The Kramer TOOLS 401C and 401DN are high performance format
converters for s-Video (Y/C) and composite video signals.
The 401C converts an s-Video input to two composite outputs as well as
simultaneously to two s-Video (Y/C) outputs, with no signal degradation.
The 401DN converts a composite video input to one s-Video (Y/C) output
with full compensation for Y/C delay.
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 and position
your Kramer 401C/401DN 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 unit
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

5.1 Connecting the 401C
To connect your 401C as illustrated in the example in Figure 3, do the following
1
:
1. Connect an s-Video source (for example, an s-Video player) to the Y/C IN
4p connector.
2. Connect the outputs
2
as follows:
The Y/C OUT 4p connectors to two s-Video acceptors (for example,
s-Video recorder 1 and s-Video recorder 2)
The COMPOSITE OUT BNC connectors to two CV acceptors (for
example, composite video recorder 1 and composite video recorder 2)
3. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
