Microphone 1 input has a 5-pole DIN (for a 3 or 5-pole DIN microphone) and a 6.3-mm phone jack connector wired in parallel. Only when connecting a microphone with a priority contact on pin 4 and 5 of the 5-pole DIN connector (2), this input has priority over all inputs except the emergency input. This microphone input can be included with a voice controlled circuit (VOX) which will overrule all the other input signals. How to activate the VOX is described in §2.1.

Note

Only use one of the two connection possibilities of each microphone input.

Figure 4.3

Depending on the position of the chime ON/OFF-switch (1), switching on microphone 1 will activate the chime. The default chime volume is -8 dB (40 V), which will be sufficient in most applications. The volume can be altered using the potentiometer VR401 on the main PCB of the unit (see §2.3).

Note

Only when connecting a 5-pole DIN microphone to the 5-pole DIN connector of microphone input 1 the chime can be activated.
