Description

Extron’s CVDA 6 EQ MX is a 1-input, 6-output composite video
distribution amplifier with level adjustment and equalization
capabilities and a buffered loopout. The adjustments can equalize a
video signal up to 500 feet away on high quality cable such as Extron
SuperFlex SHR Super High resolution coaxial cable. The buffered
loopout is not equalized and is appropriate for connecting a second
CVDA 6 EQ MX or a local monitor.

The CVDA 6 EQ MX is rack mountable and has an internal auto­switchable power supply that can accept 100VAC to 240VAC at 50 Hz to
60 Hz.

Installation and Rear Panel Connections

1. For optional rack mounting, mount the CVDA 6 EQ MX unit on
the left or right side of a 19" 1U Universal Rack Shelf (Extron
P/N 60-190-01) (figure 1).

control. The level adjustment compensates for signal amplitude
losses caused by cable resistance. The control adjusts the
composite video output signal gain, through one full turn, from ­6dB through +6dB.

Operation — With a waveform monitor connected to the far end
of one of the output cables, adjust the level so that the level is
100 IRE.

If no waveform monitor is available, adjust the level to boost the
level to achieve the best possible image.
