1 Introduction
Congratulations on purchasing the CVG-21RCA 2x1 Audio/Video/Component
Switcher.
This product is ideal for:
• Broadcast, presentation and production facilities
• Home cinema switching
• Ultra high ba ndwidth sig nal switching
The package includes the following items:
• CVG-21RCA 2x1 Audio/Video/Component Switcher
• This user manual
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
3 Overview
Your high resolution CVG-21RCA 2x1 Audio/Video/Component Switcher is a
versatile mechanical switcher that can be used for many different types of
signals. In particular, the CVG-21RCA:
• Switches 3 identical channels simultaneously, so it may be u sed for
composite video with 2 audio channels; for 3 independent composite video
channels; for one composite and one Y/C channel; for component video (YUV
or RGB), SDI, HDTV or for any other combination
• Uses an “RF” PCB design with 3 ultra high bandwidth channels,
providing bandwidth exceeding 1000 MHz (1 GHz), and is therefore suitable
for use with almost any common signal
• Is housed in a desktop enclosure and can be used in “reverse” as well –
functioning as a 1x2 switcher (toggling one source between two acceptors)
• Provides a simple solution for many switching needs and as the design is
passive, it does not need power, thus increasing its versatility
2
Achieving the best performance means:
• Connecting 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)
• Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your CVG-21RCA in a
location free from moisture and away from excessive sunlight and dust

5 Using the CVG-21RCA 2x1 Audio/Video/Component Switcher
You can use your versatile CVG-21RCA 2x1 Audio/Video/Component
Switcher as a:
• 2x1 Composite video switcher with 2 audio channels (see Figure 2)
• 1x2 Composite video switcher
• 2x1 Component video switcher (see Figure 4)
• 1x2 Component video switcher
1
with 2 audio channels (see Figure 3)

You can also use your CVG-21RCA 2x1 Audio/Video/Component Switcher as
a switcher that includes the following
2
combinations:
• One composite channel and one Y/C channel
• 3 independent composite video channels
• 2 composite video channels and a channel for unbalanced mono audio
• 3 unbalanced mono audio channels
• SDI
• HDTV
1 Due to its passive signal path, the CVG-21RCA can also operate in the opposite direction
2 Or any other appropriate combination

5.1 Connecting the CVG-21RCA as a 2x1 Composite Video/Audio Switcher
To use your CVG-21RCA as a 2x1 composite video/audio switcher, connect
the CVG-21RCA as the example in Figure 2 illustrates:
1. Connect a composite source (for example, a VCR “Composite Source 1”)
to the three INPUT 1 channels, as follows:
• Connect the composite video channel to RCA connector A
• Connect the left stereo channel to RCA connector B
• Connect the right stereo channel to RCA connector C
2. Connect a second composite source (for example, a VCR “Composite
Source 2”) to the three INPUT 2 channels, as follows:
• Connect the composite video channel to RCA connector A
• Connect the left stereo channel to RCA connector B
• Connect the right stereo channel to RCA connector C
3. Connect the three OUTPUT channels to a composite acceptor (for
example, a monitor), as follows:
• Connect the composite video channel to RCA connector A
• Connect the left stereo channel to RCA connector B
• Connect the right stereo channel to RCA connector C
4. Push in the front panel INPUT SELECTOR switch to route input 2, or
release it to route input 1.

5.2 Connecting the CVG-21RCA as a 1x2 Composite Video/Audio Switcher
To use your CVG-21RCA as a 1x2 composite video/audio switcher, connect
the CVG-21RCA as the example in Figure 3 illustrates:
1. Connect a composite source (for example, a VCR “Composite Source”) to
the three OUTPUT
1
channels, as follows:
• Connect the composite video channel to RCA connector A
• Connect the left stereo channel to RCA connector B
• Connect the right stereo channel to RCA connector C
2. Connect the three INPUT
2
1 channels to a composite video acceptor (for
example, a monitor “Composite Acceptor 1”), as follows:
• Connect the composite video channel to RCA connector A
• Connect the left stereo channel to RCA connector B
• Connect the right stereo channel to RCA connector C
3. Connect the three INPUT2 2 channels to a composite video acceptor (for
example, a monitor “Composite Acceptor 2”), as follows:
• Connect the composite video channel to RCA connector A
• Connect the left stereo channel to RCA connector B
• Connect the right stereo channel to RCA connector C
4. Push in the front panel INPUT SELECTOR switch to route the source to
Acceptor 2, or release it to route the source to Acceptor 1.

5.3 Connecting the CVG-21RCA as a 2x1 Component Video Switcher
To use the CVG-21RCA as a component video (Y, B-Y, R-Y, sometimes
called YUV or Y, Pb, Pr) switcher, connect the CVG-21RCA as the exam ple in
Figure 4 illustrates:
1. Connect a component video source (for example, a BETACAM VCR
“Component Source 1”) to the three INPUT 1 channels, as follows:
• Connect the Y component video channel to RCA connector A
• Connect the B-Y component video channel to RCA connector B
• Connect the R-Y component video channel to RCA connector C
2. Connect a second component video source (for example, a BETACAM
VCR “Component Source 2”) to the three INPUT 2 channels, as follows:
• Connect the Y component video channel to RCA connector A
• Connect the B-Y component video channel to RCA connector B
• Connect the R-Y component video channel to RCA connector C
3. Connect the three OUTPUT channels to a component video acceptor (for
example, a component video monitor), as follows:
• Connect the Y component video channel to RCA connector A
• Connect the B-Y component video channel to RCA connector B
• Connect the R-Y component video channel to RCA connector C
4. Push in the front panel INPUT SELECTOR switch to route input 2, or
release it to route input 1.
