3. WORKING PRECAUTIONS
The manufacturer is not responsible of any damage that can possibly happen to the dual channel
beltpack outside the limits of the warranty or those produced by not taking care of the working
precautions.
The intercom line DC voltage must be between the limits of the admitted power supply (12-30 VDC).
The damage caused by a connection to an improper line DC voltage is not covered by any warranty.
DANGER: Inside the unit there are high voltages, do not open it. The unit does not contain
elements that could be repaired by the user. Whenever the dual channel beltpack is
connected to the intercom lines, it carries elements with high voltages. In order to
disconnect the unit completely, you must disconnect it from the intercom lines.
CAUTION: Protect the unit from the rain and moisture. Ensure that no objects or liquids enter it. If liquid
is spilled into the unit, disconnect it from the mains and consult a qualified service technician.
Do not place the unit close to heat sources.
4. INSTALLATION
UNPACKING
Before leaving the factory, each dual channel beltpack has been carefully inspected and tested.
You can unpack and inspect the unit for any damage that may have occurred during shipment. If
any damage is found, does not connect the unit to the intercom line; notify the salesperson
immediately; a qualified service technician should inspect the unit.
Save the original packing, you could use if you need to transport the unit. NEVER SHIP THE
DUAL CHANNEL BELTPACK WITHOUT ITS ORIGINAL PACKING.
INTERCOM LINE CONNECTION
The intercom line connection in the dual channel beltpack model EM-202-3P is carried through
twin-lead shielded cable and male or female XLR 3 pin connectors. The dual channel beltpack
provides one female XLR 3 pin connector (LINE A) and a male XLR 3 pin connector (LINE B), wired

Certain rules have to be followed when installing the cables of an intercom system. This is to
avoid ground loops and to minimize the power loss and the possible effect of electromagnetic fields.
Do not connect the XLR pin 1 to the XLR metal housing or to metal wall boxes to avoid ground
loops. The ground loop could increases notably the system background noise.
Do not close the intercom line connection (avoid closed loops). Each intercom line leaves from the
master station towards the remote stations, but it does not return to the master station. If the
connection is closed, a ground loop with the increase from the system noise will take place.
Use high quality cables and minimize its longitude. The DC resistance of a low quality cable or
very long affects to the power consumption, the channels crosstalk and the system frequency
response.
Place the master station the closest possible to the maximum consumption zone; that is to say to
the zone in which more external units are placed.
5. OPERATION
The E-200 intercom system series 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, with its simultaneous listening-speaking operation system.
The E-200 system dual channel beltpack provides two independent intercom channels. Each
channel provides a CALL switch, a MIC on/off switch (TALK), a listen balance control allows to listen to
the channels independently, or a mix between the two channels.
The Dual Channel Beltpack EM-202 unit was designed for intensive use in portable applications.
An unbreakable plastic belt clip enables easy and secure suitability. Call signalling is Dual, visual and
audible for improving adaptability. The unit can be configured for dynamic or electret microphones
enabling the use of different types of headsets and hands-free earpieces in the market.

HEADSET CONNECTION
A XLR-4 type connector allows to connect a headset and a microphone to the desk station. The
headset impedance must be 200 Ωor higher (up to 2 KΩ) and the microphone must be dynamic or
electret type.
For the electret microphone type is necessary to enable the could enable the phantom power
of 9 VDC with adip-switch placed near the plastic belt clip. In order to obtain more information,
consult the special operation section.
The microphone preamplifier gain can be configured with a dip-switch placed near the plastic
belt clip in +30 or +40 dB. (In the factory set-up the microphone preamplifier gain is adjusted to +40
dB). In order to obtain more information, consult the special operation section.

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.
MIC ON/OFF/PUSH TO TALK SWITCH
The ES-200 dual channel beltpack unit is provided with two talk switches, one per
intercom channel. The TALK switch allows to enable/disable the microphone; that way,
we can speak with other units connected to the same intercom channel. If the channel A
microphone isn’t activated (for example), and the channel B microphone is activated, we
will speak with the stations connected to the channel B, but the connected stations to the channel
won’t hear us.
If the microphone is activated, its associated LED will light up, and on the other hand, if it is
disabled, its associated LED will turn off.
The TALK switches have two operation modes. When this switch is pressed quickly, the
microphone changes its state; if it was enabled, being pressed it gets disabled and turns off the
associated LED, and if it was disabled, being pressed it gets enabled and turns on the associated
LED. When the TALK switches are pressed and held, the unit will enter in the special function PUSH
TO TALK; this means that the microphone will be enabled until the switch is released.
The unit provides a MIC-KILL (turns off the MIC) system, so that when the mic is enabled it is
possible to muted it by the MIC-KILL function of the master station ALTAIR EF-200.
BUZZER ON/OFF SWITCH
This switch enables/disables the buzzer sound when the unit receives a call. When
this switch is pressed, and the buzzer is enabled, it will be disabled, and the LED indicator
will turn off. On the other hand, if the buzzer was disabled, it will be enabled and the LED indicator
will lighten up.
The buzzer sound is different when a call from the channel A is received that when it is
received from the channel B, as well as when a simultaneous call from both channels takes place.
The buzzer also sounds when any switch is pressed, emitting a short hoot.
The unit provides a BUZZER-KILL (turns off the BUZZER) system, so that when the buzzer is
enabled it is possible to muted it by the BUZZER-KILL function of the master station ALTAIR EF-200.

The BUZZER could be disabled with a dip-switch placed near the plastic belt clip and it is
possible to change its sound level with an internal preset, consult the special operation section.
LINE A AND B LISTEN BALANCE CONTROL
The listen balance control between lines A and B allows to adjust the signal mix
of both channels that appears in the headset of the dual channel beltpack. Totally to
the left, the signal that appears in the headset is only the channel A signal, totally to
the right, the signal that appears in the headset is only the channel B signal, centered it appears a
mix between both channels and in intermediate positions, it adjusts the level that we want to listen
from each channel.
CALL SWITCH
The ES-200 dual channel beltpack unit is provided with two call switches, one per
intercom channel. When one of these switches is pressed a call signal is sent to the
corresponding intercom channel. The call signal makes the LED associated with the
switch start blinking; if the buzzer is enabled (consult buzzer on/off section for more
information) an intermittent sound takes place during three seconds (the LED blinking, as well as the
buzzer sound is different if the call takes place in the channel A or B), the same as in all the units
(beltpacks, desk stations, master stations, etc.), connected to the same intercom channel.
If the CALL switch is pressed continuously, the duration of the call signal will be higher (the time
that the switch is pressed, and approximately 3 seconds more).
If a call signal is generated in an external unit (beltpacks, desk stations, master stations, etc.),
the LED associated to the CALL switch of the channel in which the call signal is received, will start
blinking and if the buzzer is enabled (see buzzer on/off section for more information) an intermittent
sound will take place during about three seconds.
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.
MIC MONITOR CONTROL
The microphone monitor control allow hear the microphone signal in the headsets even if
the TALK switches are in the off position, and regardless of the lines sidetone controls. Totally to
the left, the microphone signal is not hear in the headsets, totally to the right, the microphone signal
that appears in the headsets has the highest level, and in intermediate positions, it adjust the
microphone level that we want to listen in the headset.
SET UP DIP-SWITCH
The set up DIP-SWITCH placed at the rear side of the unit, near the belt
clip, permits the configuration of several operation parameters of the unit:
BUZZER ON/OFF
The buzzer can be configured with the position 4 of the set up DIP-
SWITCH, so remains always turned off or turned on/off depending on the front panel buzzer
on/off switch. With the position 4 of the set up DIP-SWITCH in OFF, the buzzer will remain always
turned off, and with the position 4 of the set up DIP-SWITCH in ON the buzzer will turn on/off
depending on the front panel buzzer on/off switch.

Disabling the buzzer guarantees no CALL sounds in any circumstance, as desired in theatre
or any other public performance.
FACTORY SET UP: ON.
CHANGING THE MIC GAIN
The microphone preamplifier gain could configure by means of position 3 of the set up DIP-
SWITCH in 30 or 40 dB. With the position 3 of the set up DIP-SWITCH in LOW (OFF), the gain of the
microphone preamplifier is 30 dB, and with the position 3 of the set up DIP-SWITCH in HIGH (ON)
the gain is 40 dB.
FACTORY SET UP: 40 dB (HIGH - ON).
MICROPHONE LIMITER ON/OFF
The dual channel beltpack microphone has a limiter that can be enabled / disabled with
the position 2 of the set up DIP-SWITCH. With the position 2 of the set up DIP-SWITCH in OFF, the
limiter is disabled, and with the position 2 of the set up DIP-SWITCH in ON, the limiter is enabled.
FACTORY SET UP: ON.
MICROPHONE PHANTOM POWER ON/OFF
The microphone PHANTOM power could be enabled or disabled with the position 1 of the
set up DIP-SWITCH. With the position 2 of the set up DIP-SWITCH in OFF, the phantom power is
disabled andwith the position 2 of the set up DIP-SWITCH in ON, the phantom power is enabled.
If an electret microphone is used, the PHANTOM power must be enabled and if a dynamic
microphone is used, the PHANTOM power must be disabled. The microphone PHANTOM power
is 9 VDC.
FACTORY SET UP: OFF.
6. SPECIAL OPERATIONS
In order to set-up some of the dual channel beltpack possibilities, the unit must be opened
removing the two external screws of its rear panel.
NOTE: This type of operations takes place when the unit is opened; the best thing should be to carry it
out by a qualified technician.
DANGER: Before opening the unit, disconnect it from the intercom lines.
CAUTION: Protect the dual channel beltpack from the rain and moisture, mostly if it is open. If liquid is
spilled into the unit, disconnect it from the mains and consult a qualified service technician.
CHANGING THE BUZZER LEVEL
The buzzer sound level could configure with an internal
jumper (JP1). With the jumper removed, the buzzer sound level is
lower than with the jumper placed.
The buzzer sound level should be adapted to any
circumstance (environments more or less noisy).
