.
If the amplifier to which the module
is to be connected has a simple
power supply (asymmetrical
supply), i.e. an amplifier with output-
elcos, the following resistances has
to be mounted:
C...
 R23 : 1K2
 R24 : 1K2
 R25 : 1K2
 R26 : 1K2

ATTENTION: if the involved
amplifier has a symmetrical
power supply, those
resistances may NOT be
mounted!
