Notes
This set has oodles of adjustability. Aside from the basic picture settings, this set has the following:
- NTSC 3.58 chroma trap (aka notch filter) for composite video
- Toggle between spatial and pseudo stereo
- Video noise reduction (likely a low-pass filter)
- Aphex Exciter for brightening audio mix
- A microphone jack(?)
- Purity adjustment by screen quadrant
- And a bunch of other stuff I can't figure out
Picture quality over s-video is excellent. Very clean and not overly bleedy.
This set has VM. to disable it, unplug the jumper connecting the VM board to the neckboard:
