Overview
3 Overview
The Kramer VM-30CA 1:3 Video Component / Audio Distributor is a high
performance 1:3 distributor for component video signals (HDTV compatible),
digital audio (S/PDIF) signals, and unbalanced stereo audio signals.
The VM-30CA accepts one:
Component video1 signal and distributes the signal to three identical outputs
using RCA connectors
Digital audio (S/PDIF) input and distributes it to three digital audio
(S/PDIF) outputs using RCA connectors
Unbalanced stereo audio input and distributes it to three unbalanced stereo
audio outputs using 3.5mm jacks
In addition, the VM-30CA features:
A video bandwidth of 400MHz that ensures transparent operation at the
highest resolutions
Front panel trimmers to control the level and EQ. of the Y, PB/CB, and
PR/CR video components
Audio level control for the unbalanced stereo audio outputs
The VM-30CA is housed in a desktop-sized enclosure, and is 12V DC fed.
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-30CA
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 Sometimes called YUV, or Y, B-Y, R-Y, or Y, Pb, Pr, or Y, Cb, Cr

5 Connecting the VM-30CA
To connect a VM-30CA unit as the example in Figure 2 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 3 RCA connectors and the digital audio
S/PDIF3 OUT 3 RCA connector to a home theater system (to which a
projector and speakers are connected)
3. Connect a 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 2).
4. If required, adjust4 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-30CA. After connecting your VM-30CA, switch on
its power and then switch on the power on each device
2 You can connect three component video output connectors to up to three component video acceptors. When less than three
outputs are required, connect only those outputs of the VM-30CA that are required, and leave the other outputs unconnected
3 Alternatively, connect the ANALOG AUDIO 3.5m socket (not shown in Figure 2)
4 Insert a screwdriver into the small hole and carefully rotate it, trimming the level
