Congratulations on purchasing your Kramer 401C Y/C to Composite
Converter/DA and/or 401DN Composite to Y/C Decoder, which are ideal for the
following typical applications:
•Professional presentation and display systems
•Video duplication studios, delivering high quality s-Video duplications
The 401C also provides composite video outputs for simple monitoring.
•Teleconference systems
•Conversion from s-Video to composite video (401C) or for conversion from
composite video to s-Video (401DN)

2 401C, 401DN - Getting Started
2 Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
•Review the contents of this user manual
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Do not secure the cables in tight bundles or roll the slack into tight coils
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer 401C, 401DN away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

4 401C, 401DN - 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.
3.1 Defining the 401C, 401DN
The 401C Y/C to Composite Converter/DA is defined in Figure 1.

6 401C, 401DN - Connecting the 401C, 401DN
4 Connecting the 401C, 401DN
Always switch off the power to each device before connecting it to your
401C, 401DN. After connecting your 401C, 401DN, connect its power
and then switch on the power to each device.
The following sections describe how to connect the:
•401C Y/C to Composite Converter/DA (see Section 4.1
•401DN Composite to Y/C Decoder (see
)
Section 4.2
4.1 Connecting the 401C
)
To connect your 401C as illustrated in the example in Figure 3, do the following:
1. Connect an s-Video source (for example, an s-Video player) to the Y/C IN 4-
pin connector.
2. Connect the outputs (you do not have to connect all the outputs) as follows:
The Y/C OUT 4-pin 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.
