Certain rules have to be followed when installing the cables of an interco syste to
avoid ground loops and to ini ize the power loss and the possible effect of electro agnetic
fields.
*Do not connect the XLR pin 1 to the XLR etal housing or to etal wall boxes. The
ground loop created could increases notably the syste background noise.
*Do not close the interco line connection (avoid closed loops). Each interco line
leaves fro the aster station towards the re ote stations, but it does not return to the aster
station. If the connection is closed, a ground loop with the increase fro the syste noise will
take place.
*Use high quality cables and ini ize its length. The increased DC resistance of a low
quality or very long cable affects to the stability, noise, the channels crosstalk and affects all the
interco equip ent connected to this branch.
4.5. CH-B POWER CONFIGURATION JUMPER
The rear panel includes a ju per configuration very helpful for so e installations.
Nor ally the unit connects one or the two available channels to the corresponding
installation channels A and B but there are applications where only a channel is used for
connecting to the interco line and the other channel can be used for private co unication
with an assistant or tea .
See exa ple bellow for configuration of the ju per.
When setting the ju per position first re ove the isolator provided, set the ju per in the
chosen position and set finally the isolator on the free pin.

5. OPERATION
The E-200 interco syste series are designed to allow axi u easy co unication
operations between the different control areas in usic or theatre live perfor ances, television,
cine a, conference halls, and whatever broad events where ultiple and fast co unications
are required, with its si ultaneous listening-speaking operation syste .
The ES-200 CL desk station provides two independent interco channels.
Channel selection switch A/B dictates the assigned channel to operate the CALL switch,
MIC on/off switch (TALK), listen circuit, or level volu e control. Balance listening between
channels AB is possible to adapt to the different crew levels.
The dual channel wall station incorporates a non-detachable panel icrophone. Re ote
listening function with a defined high level enables priority e ergency calls.
Re ote MIC-on by inco ing CALL allows the unit to operate as a onitor station, just to
hear the roo activity in theatre dressing roo s, dance roo s and ore.
5.1. OPERATION MODES
- PANEL MIC:
This is the default operation ode. The panel ic and speaker is enabled. To avoid
strong coupling (feedback) between the ic and the speaker, the speaker is auto atically
disabled when talking. In this ode, the TALK key only operates in PTT ode so it is not
possible to lock it, always operating as o entary.
- GOOSENECK MIC:
Connect a standard 4 pin fe ale boo icrophone in the headset connector. Set ode
GOOSENECK in the special settings setup to enable the speaker and allow the ON/OFF/PTT
talk key nor al operation.
- HEADSET:
This ode is auto atically set when a headset is detected. The panel ic and the
speaker are disabled. Talk key reverts to ON/OFF/PTT nor al operation.
5.2. CALL SWITCH 1
The ES-203 CL desk station unit is provided with a CALL switch and operates over the
selected channel A or B or both A+B. The CALL switch allows to generate a call signalling sent
to the selected interco channels.
The call signal akes the LED associated with the switch start blinking; if the buzzer is
enabled (consult buzzer on/off section for ore infor ation) an inter ittent sound takes place
during three seconds on the desk station and to the units (beltpacks, desk stations, aster
stations, etc.) connected to the sa e interco channel.
If the CALL switch is pressed continuously, the duration of the call signal will be higher
(the ti e that the switch is pressed, and approxi ately 3 seconds ore).
ES-203 CL DUAL CHANNEL DESK STATION

If a call signal is generated in an external unit, the call origin is identified by the channel
select A or B indicators blinking and if the buzzer is enabled (see buzzer on/off section for ore
infor ation) an inter ittent sound will take place during about three seconds.
5.3. BUZZER ON/OFF 2
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 call origin is identified by the channel select A or B indicators blinking.
The buzzer also sounds when any switch is pressed, e itting a short beep.
The buzzer can be disabled/enabled by holding down the key for 2. Led indicator flashes
quickly.
Buzzer key is used for setting up the unit by holding down the key for 12 seconds. See
SPECIAL SETTINGS configuration bellow.
Re ote buzz kill generated fro the base unit would disable the buzzer. Led indicator
flashes indicating re ote buzz kill function is in operation.
Nor ally the buzzer and the ic key initializes with the sa e state as when the desk
station was switched off, i.e. it re e bers last state but the unit can be configured to initialize
both in off state. This would avoid feedbacks or undesirable sounds at start up. See SPECIAL
SETTINGS configuration bellow.
UNIT FACTORY DEFAULT. For a factory default of all unit settings hold down this key for 22
seconds.
5.4. TALK (MIC) button 3
The ES-203 CL desk station unit is provided with a TALK switch and operates over the
selected channel A or B or both A+B. The TALK switch allows to open the icrophone used;
that way, we can speak with other units connected to the selected interco channels.
The TALK switch have two operation odes. When this switch is pressed quickly, the
icrophone changes its state; if it was enabled it gets disabled and turns off the associated
LED, and if it was disabled 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 eans that the icrophone will be enabled until the switch is released.
Use this ode as preferred to reduce the global noise on the syste .
When using the panel ic, the unit only per its this ode to avoid feedback on the
speaker.
The unit provides a MIC-KILL (turns off the MIC) syste , so that when the ic is enabled
it is possible to be re ote uted by the MIC-KILL function fro any ALTAIR EF/PS/WBS base
stations. This MIC-KILL syste is proprietary so is not co patible with other interco brands.
5.5. PANEL MICROPHONE 4
The incorporated icrophone allows talking with the interco lines connected to the desk
station.
In order to avoid feedback, the speaker is disconnected as long as TALK key is
depressed.
Panel ic is disabled auto atically when a headset is connected.

-EC-200 Cue Light aster station,
-ER-200 standalone Cue Light receiver.
-ES-203 CL wall/desk interco station with Cue Light. See description above.
All three devices are designed to be integrated into the Altair wired interco syste sharing the
power supply and wiring.
As seen on the diagra , the aster panel EC-200 akes the link fro the existing
interco syste to the cue light syste . It incorporates a filter between both syste s acting as
separator of both worlds, the cue light signals and the interco line. On the diagra , the sa e
cue signal is driving the two ES203 CL and the ER-200.
Cue light signals and interco are now sharing the sa e wiring to be connected to the
receivers ER-200 or the new co bined cue+interco base stations ES-203 CL in standalone or
chained stations (up to 8 units).
Multiple EC-200 plus cue light receivers ER-200 (or ES-203CL) can be used in parallel to
the existing interco lines so having separate cue signals as used on co plex shows i.e.
