INSTALLATION
6.1
Rack Mounting
The Kramer 401D
xl
may be rack mounted in a standard 19” (1U) EIA rack assembly, using a special TOOLS
Adapter (1U or 3U) and two mounting brackets (see section 4.1). They can be also table mounted using the
mounting brackets provided. These devices do not require any specific spacing above or below the unit for
ventilation. To mount any of the machines, follow the installation instructions enclosed with the machine.

CONNECTING TO VIDEO DEVICES
Video sources and output devices (such as monitors, projectors or recorders) may be connected to the machine
through the BNC and/or 4P type connectors located on the back of the unit. Unused inputs are terminated to
75ohm, and active inputs should be terminated by the connecting source. All signal connections that use more
than one cable interconnecting between devices should be of equal length.

USING THE MACHINE
8.1
Turning on the Machine
NOTES
1)
The machine should only be turned on after all connections are
completed and all source devices have been turned on. Do not
attempt to connect or disconnect any video, audio or control
signals to the machine while it is turned on!
2)
The socket-outlet should be near the equipment and should be
easily accessible. To fully disconnect equipment, remove
power cord from socket.
1)
Connect the machine's DC socket to the power supply (provided with the machine). Observe proper
polarity! Note that the LED on the panel is illuminated.
2)
Operate the source and the acceptors.
8.2
Composite / YC Video Selection
Selecting either Composite or Super video as input is simply done by using the
INPUT SELECTOR
switch on
the front of the machine. When the input selector is pressed-in, the Y/C INPUT is selected as the source (passed
through.) When the switch is released, the Composite Video input is selected as the source to be decoded by the
machine to Y/C.
