Pluggable Microphones to the DCN-DDI Dual Delegate
Interface.

The microphone connection panel (refer to figure 22.1)
contains:
1 Output level plug - Connect the microphone
connection panel to a DCN-FCS Channel Selector to
prevent acoustic feedback (refer to section 22.5.2)
2 Microphone socket - Connects a DCN-MICL or
DCN-MICS Pluggable Microphone to the
microphone connection panel (refer to chapter 17).
3 Solder spot - Enables or disables the green LED

22.3 Internal settings

Use the solder spot to enable or disable the green LED
ring of the connected DCN-MICL or DCN-MICS
Pluggable Microphone (refer also to section 17.4).
table 22. 1 : Solder spot (* = default)
Solder spot Description
Not soldered* The green LED ring of the
connected DCN-MICL or
DCN-MICS Pluggable
Microphone is enabled.
Soldered The green LED ring of the
connected DCN-MICL or
DCN-MICS Pluggable
Microphone is disabled.
When the microphone connection panel is connected to
a dual delegate interface that is in the dual delegate with
one microphone mode, you must disable the green LED
ring. If you do not disable the LED ring, the LED ring
of the connected microphone cannot show the correct
condition. For example, first delegate 1 enables the
microphone (red) and then delegate 2 makes a
request-to-speak (green). Although the microphone is
enabled, the green LED ring comes on when delegate 2
pushes the microphone button.

22.4 Installation

The microphone connection panel is a flush-mounted
device. Refer to chapter 19 for the installation
procedures.
