ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The DA1406WM is a 1-in 6-out MAC distribution
amplifier designed to connect a single computer
video source to as many as six scan rate
compatible displays. The DA1406WM will pass an
analog video signal up to 1.5 V p-p. Using AGC
sync circuitry, the DA1406WM converts incoming
TTL sync levels to a standard 4V p-p level.
All input and output connectors are 15-pin D
female. This provides superior durability, as the
pins on male connectors can be easily bent
disabling the entire unit. A male to male MAC cable
will typically be required for connection between the
computer and the input to the DA1406WM.
Four ID bit switches allow a user to boot up a
computer at a variety of monitor settings. Though
primarily designed for use with displays using
15-pin D (MAC-type) connectors, the DA1406WM
can pass RGBHV, RGBS, and RGsB format
signals. Adapter cables may be necessary to
accomplish the appropriate connector change.
The DA1406WM is great for desktop use, but can
also be rack-mounted using optional hardware.
