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 fl atness to 270 MHz
• Computer compatible sychronizing circuitry
• HD-15 female connectors for the input and each output
• Full cable equalization control for the output channels
• Compatible with all computer standards
• 12VDC , 0.5A Wall plug-in power supply with 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 connections 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 connector.
Adjust the cable equalization, with the variable control for minimum distortion using an appropriate test signal or full motion video.
Perform the final operational check.
