UMA1209 Rev. A
Dual A/V Splitter With EDID
1. Introduction
The Model 200A is a 2-channel VGA distribution amplifier (splitter)
with stereo audio and EDID routing and emulation capabilities.
The RGBHV (VGA) input video signal is terminated and amplified for
driving each output. The 3.5mm audio input is ground isolated to
prevent ground loop noise and hum and is also amplified for driving
each output.
The EDID (Extended Display ID) data that the video source sees can
be routed from the LCD connected to OUTPUT #1, or emulated using
internal EDID memory in the splitter. A recessed 2-position switch is
used to determine the EDID routing. The internal EDID is generic and
designed to render an image on most displays (please see product
webpage for EDID details). To change the internal EDID, additional
EDID programmer hardware is required (Model USB-EDID-HD15)
2. Features
Uses 500 MHz video amplifiers for clear and crisp image
Splits both Video and Audio
Isolated audio input provides immunity to ground loop noise
EDID routing switch (internal or from downstream monitor)
Can be powered from VGA source (some sources may not
provide power on their VGA output)
Includes power adapter
Compact sturdy metal case
Made in the USA
