) and the microphone must be dynamic or electret type.
The microphone preamplifier gain can be configured with an internal preset in +30 or +40
dB. (In the factory set-up the microphone preamplifier gain is adjusted to +30 dB)
For the electret microphone type it is necessary to enable the phantom power of 9 VDC with
an internal preset. In order to obtain more information, consult the special operation section.
The next list shows the XLR pins correspondence:

NOTE:
Headphones can be with a double or single muff. In case of using a double muff
headphone, the two speakers should be wired in parallel mode.
HEADSET VOLUME CONTROL
The volume control allows attenuating or amplifying the signal sent to the
headphones. This control adjusts the listen level to the headphones as you wish.
REMOTE MUTE ALL MICS AND BUZZER SWITCHES
These switches allow to disable all the microphones (ALL MICS) and all
the buzzers (BUZZERS) of both channels of the intercom system (including all
the wired and wireless beltpacks, desk station units and master station slave
units) except the one from the base station from that these switched are
activated (the buzzer remote mute affect to the base station).
The remote mute ALL MICS switch carries out the function upon pressing it. This means that
the units (wired and wireless beltpacks, desk stations units, etc.) connected to the system can turn
on the microphones again when it’s required. When this switch is pressed, its associated LED turns
on during a moment.
The BUZZERS switch, on the other hand, carries out an on/off function. If the remote mute
buzzers function was enabled, when the remote mute buzzers switch is pressed the remote mute
buzzers function is disabled and the associated LED becomes turned off (in this moment all the
external units could enable their local buzzers again); if, on the other hand, it was disabled, when
the remote mute buzzers switch is pressed the remote mute buzzers function is enabled and the
associated LED becomes turned on (at this moment the buzzers of all the external units will be
disabled and they can not be enabled again locally).
The BUZZER ON/OFF of the base station is carried out with the BUZZER REMOTE MUTE,
enabling/disabling the buzzer sound when the unit receives a call or when the user presses a key.
STAGE ANNOUNCE (SA) SWITCH
The SA switch allows to enable the SA (stage announce) OUTPUT placed at the rear
panel, which normally is disabled, and to carry out this way the microphone signal
sending picked up in the HEADSET to another audio systems, activating at the same time the
multipurpose relay (PA OUTPUT RELAY) placed at the rear panel (factory set-up). This switch has an
associated LED that indicates the state of the SA output (the LED is on when the microphone is
routed to the PA output).
