Pace PRD800/900 ADX switching. |
It's quite simple to arrange for an ADX converter to be automatically switched as required. The control wire from the ADX should be connected to pin 24 of IC U9, the NICKY 2 chip. This is the switching line for the PAL/MAC filtering feeding the baseband output to the decoder SCART - it has no other effect if are not using an external decoder.
To arrange switching the ADX, just set the PAL/MAC option in the tuning menu accordingly, MAC for ADX off, and PAL for ADX on. This does mean you have to alter all your existing channels, but once done the ADX works flawlessly.
