KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The Kramer VM-50CA 1:5 Video Component / Audio Distributor is a high
performance 1:5 distributor for component video signals (HDTV compatible),
digital audio (S/PDIF) signals, and unbalanced stereo audio signals.
The VM-50CA accepts one:
Component video1 signal and distributes the signal to five identical outputs
using RCA connectors
Supports all HDTV resolutions, including 1080p
Digital audio (S/PDIF) input and distributes it to five digital audio
(S/PDIF) outputs using RCA connectors
Unbalanced stereo audio input and distributes it to five pairs of
unbalanced stereo audio outputs, using RCA connectors
In addition, the VM-50CA features:
A video bandwidth of 400MHz that ensures transparent operation at the
highest resolutions
Underside trimmers to control the component video Y, Pb/Cb, and Pr/Cr
levels and EQ.
Audio level control for the unbalanced stereo audio output
The VM-50CA is dependable, rugged and fits into one vertical space (1U) of
a standard 19” professional rack.
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-50CA
away from moisture, excessive sunlight and dust

Installing the VM-50CA on a Rack
Before Installing on a Rack
5 Installing the VM-50CA on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
How to Rack Mount
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range
Storage temperature range
Storage humidity range
When installing on a 19" rack, avoid hazards by taking
care that:
It is located within the recommended environmental
1
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
Once rack mounted, enough air will still flow around the
2
machine.
The machine is placed straight in the correct horizontal
3
position.
You do not overload the circuit(s). When connecting
4
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the product
label.
The machine is earthed (grounded) in a reliable way
5
and is connected only to an electricity socket with
grounding. Pay particular attention to supply
connections other than direct connections to the
branch circuit (for example, the use of power strips),
and that you use only the power cord that is supplied
with the machine.
5 to 65% RHL, non-condensing
-20 to +70 Deg. Centigrade
5 to 95% RHL, non-condensing
CAUTION!!
To rack-mount a machine:
1
Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the machine
(3 on each side), and replace those
screws through the ear brackets.
Place the ears of the machine
2
against the rack rails, and insert the
proper screws (not provided) through
each of the four holes in the rack
ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be removed
for desktop use
Always mount the machine in the rack
before you attach any cables or
connect the machine to the power
If you are using a Kramer rack adapter
kit (for a machine that is not 19"), see
the Rack Adapters user manual for
installation instructions (you can

Connecting the VM-50CA
6 Connecting the VM-50CA
To connect a VM-50CA unit as the example in Figure 3 illustrates, do the
following1:
1. Connect a component video source (for example, an HDTV satellite receiver)
to the Y, Pb/Cb, and Pr/Cr IN RCA connectors, and to the S/PDIF INPUT
RCA connector.
2. Connect2 the:
Y, Pb/Cb, and Pr/Cr OUT 1 RCA connectors to the component video
acceptor (for example, a plasma display), and the digital audio
S/PDIF3 OUT 1 RCA connector to an AV-Receiver
Y, Pb/Cb, and Pr/Cr OUT 5 RCA connectors and the digital audio
S/PDIF3 OUT 5 RCA connector to a home theater system
3. Connect the power cord (not shown in Figure 3)4.
4. If required, adjust5 the audio level, the Y, Pb/Cb, and/or Pr/Cr output
signal level, and/or the Y, Pb/Cb, and/or Pr/Cr cable compensation
equalization level.
1 Switch OFF the power on each device before connecting it to your VM-50CA. After connecting your VM-50CA, switch on
its power and then switch on the power on each device
2 You can connect the component video and audio outputs to up to five component video and audio acceptors. When less than
five outputs are required, connect only those outputs of the VM-50CA that are required, and leave the other outputs
unconnected
3 Alternatively, or in addition, connect the ANALOG AUDIO RCA connectors (not shown in Figure 3)
4 We recommend that you use only the power cord that is supplied with this machine
5 Insert a screwdriver into the small hole and carefully rotate it, trimming the level
