6. Connections and confi gurations

6.1. MIC 1 input through DIN connector

Symmetric input through a 180° DIN connector, with a sensitivity of
– 60dB.
Pin no. 4 provides a voltage of 24V DC (maximum 100mA) which can
be used to supply low-consumption devices (MEF-25DP, MEF-25DPG,
MD-94R4 consoles....).
It has a speech preference contact. To activate it, join pin no. 5 with
pin no. 2 (earth). With the MIXER dipswitch OFF, when the speech
preference is activated, MIC 1 has priority over the remaining
microphones and the AUX inputs (see section 6.9).
Optionally, a balanced line transformer can be connected to this input;
in this case, the signal would be transmitted through pins 1 and 3 of
the DIN connector DIN and the earth in pin no. 2 (See Figure 6).

6.2. MIC 1, 2, 3, 4 and 5 inputs
(XLR connectors)
MIC.1 and MIC.2 inputs on AXD-30
These are symmetric inputs through XLR connectors,
with a sensitivity of – 60dB.
To activate the speech preference, join the contact of
the PRIORITY CONTROL INPUT strip to the earth (See
Figure 10).
Optionally, a balanced line transformer can be connected
to them; in this case, the signal is connected to contacts
2 and 3 of the XLR connector and the earth is connected
to contact no. 1 (See Figure 8).
Each microphone input can provide a "PHANTOM"-
type supply of 24V DC. For this purpose the PHANTOM
dipswitch (see Figure 11) of the corresponding input
must be moved to the ON position, and the microphone
must be connected as shown in Figure 9.
6.3. CHIME confi guration
The pre-announcement signal is enabled through this
dipswitch. This signal is activated when the speech
preference contact is closed. It can be enabled
independently for each of the Micro inputs.
It is possible to adjust the level of the pre-announcement
signal by means of the VR301 internal potentiometer on
models AXD-60/120/240 and by means of the VR201 on
the AXD-30.
