4.1.2 Priority microphone (input 1)
The priority microphone (or a generic call station) that
can be used with push to talk (PTT) should be
connected to “microphone/line 1 input with trigger”.
The PTT mode can be activated by setting the DIP
switch (2) at the rear of the unit.
Microphone/line 1 input with trigger has priority over
all other microphone/line inputs. If, however, the “Tel.
emergency/70V input” receives a signal, all inputs
including microphone/line 1 input with trigger will be
overruled.
The microphone/line 1 input with trigger has a Euro
style pluggable screw terminal connector. This Euro
style pluggable screw terminal connector has a trigger
input, which can be used in combination with the Euro
connector.
The priority microphone can be connected to the
microphone/line 1 input with trigger as follows:
• Euro connector with trigger. See figure 4.2.
• Euro connector only (without trigger).
Set the DIP switch settings for microphone/line 1 with
trigger, as required. See section 4.3.
Note
When connecting an unbalanced line level
(200 mV) signal to the microphone/line input,
connect it as follows: Signal to pin 2, pin 1 and
pin 3 to ground.
