The general safety information in this summary is for operating
personnel.
Read Instructions Read and understand all safty and operating
instructions before using this equipment. Keep the instructions
handy.
Do Not Remove Covers or Panels There are no user-serviceable
parts within the unit. Removal of the top cover will expose
dangerous voltages. To avoid personal injury, do not remove the
top cover. Do not operate the unit without the cover installed.
Power Source This product is intended to operate from the
specified wall plug-in transformer. Do not use any orther power
source.
Grounding the Product This product is grounded through the
grounding conductor of the power cord. To avoid electrical shock,
plug the power cord into a properly wired receptacle before
connecting to the product input or output terminals.
Use the Proper Power Cord Use only the power cord and
connector specified for your product. Use only a power cord that is
in good condition. Refer cord and connector changes to qualified
service personnel.
Do Not Operate in Explosive Atmospheres To avoid explosion,
do not operate this product in an explosive atmosphere.

INTRODUCTION
The all new CDA - 4 and 6 are ultra high resolution, ultra high bandwidth 1 x 4
and 1 x 6 computer distribution amplifiers suitable for applications requiring the
highest possible video quality. The output channels on each unit
have cable equalization permiting long cable runs while maintaining excellent
signal integrity for even the highest video resolutions.
Not only do these two units have over 375 MHz of bandwidth but they also have
the FSR computer compatible sychronizing circuitry to ensure a rock stable
video image at any resolution and signal level.
The outputs are equalized to maintain excellent signal integrity for all video
resolutions. Cable runs of up to 150 feet are possible with 162 MHz of full
amplitude bandwidth and 0.5 dB peaking. Peaking remains below 0.5 dB even
at 0.2V p-p input level.
Channel-channel matching (red vs green/red vs blue) response is extremely
flat. About 0.25 dB out to 320MHz
It will restore the bandwidth of 150' of the design cable to 162 MHz, with a
0.5 dB flatness to 143MHz at full 0.7V p-p amplitude.At 0.2V p-p, these
figure become 305MHz and 256MHz respectively
This means that the signal you feed into the CDA-4 or CDA-6 will arrive at
the far end of the cable with an almost immeasurable amount of loss and no
distortion due to peaking effects.
FEATURES
•Minimum 350 MHz of bandwidth fully loaded
• +/- 0.5 dB flatness to 270 MHz
• Computer compatible sychronizing circuitry
• HD-15 female connectors for the input and each output

• Compatible with all computer standards
• UL amd CSAapproved external power source (wall plug-in) with special
locking connector
APPLICATIONS
• Boardrooms
• Houses of Worship
• Control Rooms
• Classrooms
• Staging and Rental

INSTALLATION and OPERATION
Do not connect the power line cord until all the video connec-
tions are completed.
Mount the unit in the equipment rack, using the supplied rack
mounting.
Connect all the video cables per the diagram. Please read the note
concerning output 2 on the application drawing.
Connect the power cord. Note the robust locking power connec-
tor.
Adjust the cable equalization, with the variable control for mini-
mum distortion using an appropriate test signal or full motion
video.
Perform the final operational check.
