SpeechLine IS microphone series | 29
B) Connecting microphones to a
DSP with logic function
To establish a logic connection in addition to the audio connection:
왘 Use a 3-wire cable (Ø 0.14–0.5 mm
2
) to connect the microphone or the
table stand to a GPIO port or logic port of the DSP.
왘 Lay all cables in such a way that other pe
rsons cannot trip over them
and injure themselves.
왘 Observe the connection inst
ructions in the instruction manual of your
DSP.
왘 Set the slide switch for setting the behavior of the microphone button
to ON in order to activate the “DSP remote mode”.
I
n “DSP remote mode”, the microphone is permanently on and is muted
or activated via the DSP. The microphone thus permanently provides a
reference signal for AEC algorithms in the DSP.
