Peder,

That output is KEYLINE OUT and can be used for *any* device - amplifiers 
are most common.
If you have more than 2 devices connected to that KEYLINE output, there 
may be a voltage conflict between your external devices - the open 
circuit voltages for the different devices may be different and cause 
current to flow from one device to another.
Note that this is not a KX3 problem, it is a problem between the 
multiple devices external to the KX3.

Nothing should change in the KX3 functionality due to the KEYLINE OUT.

73,
Don W3FPR
