Specifications

SYSTEM EXPANSION
Audio buffers and data switches feed a 25 pin
subminiature "D" connector for system expansion
through CR10s.
VIDEO SWITCHING
All video signal switching is done by MOSFET
switches.
VIDEO BUFFER AMPLIFIERS
Video buffer amplifiers feed the video outputs to
assure perfect matching and no loss in picture quality.
The response of the video section is 1 Hz to 12MHz so
high resolution signals present no problem to the C39.
RF OUTPUT
TV channel 3 or 4 output is provided by an internal
modulator. This signal can be used to feed remote areas
over a 75 ohm coaxial cable.
