6. Connections and configurations

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
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
"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 configuration

The pre-announcement
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
60/120/240 and by means of the VR201 on the
AXD-30.
