Extron electronic CVDA 6 EQ MX Installation, Front Panel Controls and Indicators, Description

Installation

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 auto- switchable 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).

		remove them.
	b.	Mount the CVDA 6 EQ MX on the rack shelf, using two
		4-40 x 1/8 screws in opposite (diagonal) corners to secure the
		case to the shelf.
2.	Connect the composite video input to the input BNC connector on
	the rear of the CVDA 6 EQ MX (figure 2).
3.	Connect the desired devices to the composite video output BNCs
	on the rear of the CVDA 6 EQ MX.
4.	Connect power to the CVDA 6 EQ MX.

2Level adjustment — This control is similar to a TV’s brightness 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.
