You are right it is ambiguous, so I checked my CK-7W with an avo. The mute line is normally floating, then switches to ground when a call is made.

I had to use a pull-up resistor (hacked into the CK-7W harness) to get the empeg to recognise an incoming call.


Cool. But note that my CK-7W is working great without this mod. The 'Sense' section of the config.ini on my player contains this:

[sense]
muteaction=0
mute=-1

I presume this is the magic that makes it work.
