INTRODUCTION
The CDA-2EQA, is an ultra high bandwidth 1x2 Distribution
Amplifier with Equalization for applications requiring the highest
possible video quality. Computer video signals quickly lose color
and clarity after about 25 feet. Unbalanced audio is prone to hum
and buzz. This unit will permit cable runs of 175 feet.
You spend a significant amount of time generating the best possible
image as well as the highest quality audio, don't trust those signals
to retain that fidelity in a long cable run. The CDA-2EQA will
compensate for the cable's shortcomings and deliver both the video
and audio to it's destination with the same fidelity that it was
created with. High bandwidth and flat frequency response - just
what you need.
To insure the best possible signal reproduction, the CDA-2EQA has
been designed to provide up to 525 MHz of bandwidth, ensuring
compatibility with today's and tomorrow's most demanding video
signal requirements. The audio is also handled properly resulting in
a balanced audio drive.
The CDA-2EQA solves problems and more in one easy to install
package.It combines an ultra high bandwidth video line driver and
an active audio balancer into one easy to install package. The unit
also features user selectable cable equalization, a fully buffered
local monitor output, and greater than 525 MHz of bandwidth.

Connect the audio output cables to the captive screw terminals
labeled “Audio Out”. The appropriate wiring configuration for
balanced and unbalanced connections is shown on the next page.
Set the cable equalization jumpers for optimum performance at the
desired cable length (LOW = 0 - 60', MED = 60 - 125',
HI = 12 5- 175'). These settings are based on WP 8255 (West Penn)
cables or equivalint.
Connect the 9 VAC power supply output to the locking Power In
connector
Confirm proper video and audio operation before mounting the
CDA - 2EQA
Use the supplied brackets to mount the CDA - 2EQA to the
underside or topside of the table.
