Connection of switching-inputs
You can use the switching-inputs at the terminals X1/3 – X1/6 to trigger four different
functions (see page

).
All switching-inputs of the sound module are negative switching. To trigger a
function, you have to connect the negative pole of the power supply to the
corresponding input. Generally switching units (such as our OKA-4, RC-SM-4 or
other standard multi-switch-modules) are used for this purpose. These modules are
normally negative switching, that’s why only the output of the switching module must
be connected to the input of the sound module.
