PRELIMINARY
About the Extender Series VGA Line Drivers
The Extron Extender Series are one-input VGA–UXGA line
drivers with audio. There are nine models in the series:
Extender AAP, Extender AAP EX, Extender WM, Extender D,
Extender WM AAP, Extender WM AUS, Extender MK,
Extender AKM UK AAP, and Extender AKM MAAP. They
boost the video signal between a laptop or desktop computer
and a monitor or projector. Each has a 300 MHz (-3 dB) video
bandwidth.
Each line driver accepts one computer-video input and one
stereo audio input. Each Extender also features one buffered
VGA-type RGB output and one stereo audio output. With
an optional Mac/VGA adapter, the Extender can also buffer
Macintosh signals.
