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.
