Connecting products via the logic function

Once you have established the audio connection (see previous chapter),
you can connect the products of the IS microphone series featuring a logic
port (shown on the left) to the DSP.
The logic port passes on status information on the microphone button
(microphone button pressed/not pressed) to the DSP. Via the logic output
of the DSP, you can additionally control the status of the signal light ring
of the microphone button.
The logic output also allows you to integrate and control several MAS 133
inline switch boxes in a system.
The following chapters provide
A) information on how to connect the MAS 133 inline switch box to a DSP
B) information on how to connect microphones
C) an example installation for the Sennheiser TeamConnect system
A) Connecting the MAS 133 inline switch box to the DSP via the logic
function
The way you connect the MAS 133 inline switch box determines which
information is passed on to the DSP.
