Review the contents of this user manual
3 Overview
The CVG-10ARxl is a state-of-the-art 1:10 video audio distribution amplifier
using BNC connectors for composite video, and RCA connectors for
unbalanced stereo audio signals. The CVG-10ARxl accepts a composite
video input and distributes the signal to 10 identical outputs.
In particular, the CVG-10ARxl:
Includes looping connectors for connecting to a local monitor, other
acceptor, or for forming larger systems1
Has a video bandwidth of 360MHZ, ensuring transparent performance
with typical video and audio sources
Can function as unbalanced stereo audio or balanced2 mono audio
(selected via an audio control button)
Can output video signals that are DC or AC coupled for maximum
flexibility (selected via a coupling button)
Has front panel video trimmer controls3 for output level and cable
1 For example, you can connect 3 CVG-10ARxl units to make a 1:30 video audio distribution amplifier (see section 6.2)
2 Recommended for low signal transmission over long distances or in audio b roadcasting studios for high quality signal
recreation
3 The video outputs are arranged in two blocks of 5 outputs (outputs 1 to 5, and outputs 6 to 10). Each block can be separately
trimmed for output level and cable equalization (EQ.) thus achieving different compensations for different cable lengths

equalization (EQ.), as well as audio trimmer controls for left and right gain,
with an enable / disable control button
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 and
positioning your CVG-10ARxl away from moisture, excessive sunlight and
dust

6 Using the CVG-10ARxl Video Audio Distribution Amplifier
You can connect:
A single CVG-10ARxl unit (see section 6.1)
Several CVG-10ARxl units to increase the number of outputs (see section
6.2)
6.1 Connecting a CVG-10ARxl Video Audio Distribution Amplifier
You can connect a single CVG-10ARxl Video Audio Distribution Amplifier
unit as a 1:10 video audio DA, in which audio is unbalanced stereo audio (left
and right) or balanced mono audio (+ and -).
To connect the CVG-10ARxl as a 1:10 video unbalanced stereo audio DA,
do the following1:
1. Connect a video audio source (for example, a composite VCR) to the
VIDEO IN BNC connector and to the left and right AUDIO IN RCA
connectors.
2. Connect the 102 VIDEO OUT BNC connectors and the 10 left and right
AUDIO OUTPUT RCA connectors to the video audio acceptors3 1 to 10.
3. Connect the power cord to the mains electricity.
4. Push in the Term button to terminate the line to 75.
5. Release the BAL/ST button to select unbalanced stereo audio operation.
6. Adjust4 the video trimmer controls5 for output signal level and/or cable
compensation equalization level, if required.
7. If audio control adjustment is required for left and/or right gain, push in
Enable/Disable button, and then adjust3 the trimmer controls.
1 Switch OFF the power on each device before connecting it to your CVG-10ARxl. After connecting your CVG-10ARxl,
switch on its power and then switch on the power on each device
2 As required. Up to 10 outputs can be connected on the CVG-10ARxl. Not all outputs need to be connected
3 For example, VCR units
4 Insert a screwdriver into the hole and carefully rotate it, to trim the level
5 The video outputs are arranged in two blocks of 5 outputs (outputs 1 to 5, and outputs 6 to 10). Each block can be separately
trimmed for output level and cable equalization (EQ.) thus achieving different compensations for different cable lengths

6.2 Increasing the Outputs
You can increase the number of outputs by interconnecting CVG-10ARxl
units. The example in Figure 2 illustrates how to connect 3 units to increase
the number of outputs from 10 to 30.
To form a 1:30 video and unbalanced stereo audio DA, do the following1:
1. Connect a video audio source (for example, a composite VCR) to the
VIDEO IN BNC connector and to the left and right AUDIO IN RCA
connectors of the first CVG-10ARxl unit.
2. Connect the video LOOP BNC connector of the:
First CVG-10ARxl unit to the VIDEO IN BNC connector of the second
CVG-10ARxl unit
Second CVG-10ARxl unit to the VIDEO IN BNC connector of the third
CVG-10ARxl unit
3. Connect the left and right AUDIO LOOP RCA connectors of the:
First CVG-10ARxl unit to the left and right AUDIO IN RCA connectors
of the second CVG-10ARxl unit
Second CVG-10ARxl unit to the left and right AUDIO IN RCA
connectors of the third CVG-10ARxl unit
4. Connect the 10 VIDEO OUT BNC connectors and the 10 left and right
AUDIO OUTPUT RCA connectors of the:
First CVG-10ARxl unit to the video audio acceptors2 1 to 10
Second CVG-10ARxl unit to the video audio acceptors2 11 to 20
Third CVG-10ARxl unit to the video audio acceptors2 21 to 30
5. On the first and second CVG-10ARxl units, release the Term button. On
the third CVG-10ARxl unit, push in the Term button to terminate the line
to 75.
6. On each CVG-10ARxl unit:
Connect the power cord to the mains electricity
Release the BAL/ST buttons to select unbalanced stereo audio operation
Adjust3 the video trimmer controls4 for output signal level and/or cable
1 Switch OFF the power on eac h device before connecting it to your CVG-10ARxl units. After connecting the CVG-10ARxl
units, switch on their power and then switch on the power on each device
2 For example, VCR units
3 Insert a screwdriver into the hole and carefully rotate it, to trim the level
4 The video outputs are arranged in two blocks of 5 outputs (outputs 1 to 5, and outputs 6 to 10). Each block can be separately
