WB-200 SERIES INTERCOM SYSTEM — WBS-200 DUAL CHANNEL WIRELESS BASE STATION
5. OPERATION
The E-200 series intercom system are designed to allow maximum easy communication
operations between the different control areas in music or theatre live performances, television,
cinema, conference halls, and whatever broad events where multiple and fast communications are
required, by means of its simultaneous listening-speaking operation system.
The system comprises a powered base station WBS-200 and battery powered belltpacks WBP-
200.
Base station is designed to operate in stand alone or “Master” mode enabling full duplex clear
and secure communication with up to four beltpacks and the base operator in simultaneous party
line mode. For large system operation, the unit can be used in “Slave” mode by wiring units across
the coverage area, so expanding the number of wireless users in a cellular arrangement.
Depending of the installation, base stations can also be powered remotely from a wired EF-200
base station .The base incorporates party line outputs to drive standard EM-201 wired beltpacks.
The wired connection is compatible with Espiral™, Clear-Com™ and similar compatible 2 and
4 wire systems.
The global all mic (Mic-Kill) and buzzers (Buzz-Kill) mute systems in both channels, allow to
control the line noise, as well as the ambient noise.
HEADSET CONNECTION
A XLR-4 type connector (XLR-4-32) and a TINY Q-G type connector wired in parallel mode,
allows to connect a headset and a microphone to the master station. The headset impedance
must be 200 Ω or higher (up to 2 KΩ) 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 +40 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
units) except the one from the base station from that these switched are
activated (the buzzer remote mute affect to the base station).
