Note:
The digital protocol with the most possibilities is the highest
order digital protocol. The sequence of digital protocols in
descending order is:
Priority 1: mfx
Priority 2: DCC
Priority 3: MM
If two or more digital protocols are recognized in the track,
the decoder automatically takes on the highest value digital
protocol.For example, if mfx & MM are recognized, the mfx
digital protocol is taken on by the decoder. Individual proto-
cols can be deactivated with Parameter CV 50.
