WB-200 SERIES INTERCOM SYSTEM — WBS-200 DUAL CHANNEL WIRELESS BASE STATION
1. INTRODUCTION
Congratulations on your purchase of the ALTAIR dual channel wireless base station WBS-200 of
the WB-200 series wireless intercom system. There is a lot the characteristics that make of the ALTAIR
WB-200 series one of the most highlighted in the audio professional market, some are enumerated
here:
Dual pre-amble diversity antenna system, detects and selects the higher radio signal ensuring better
coverage and minimum drop-outs.
Digital encryption process allows high security conversations.
Two detachable omni antennas are provided with the unit. External high gain directive antennas
can be mounted when desired to increase the coverage area .
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.
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 ALTAIR WBS-200 unit incorporates an internal worldwide voltage operation power supply that
powers all the system. In case of a short circuit on any point of the line, the unit shuts down with
automatic and instantaneous reset.
Before beginning it is important to read this manual. This manual will help you to install and use
your new intercom master station. It is very important to read it carefully, mainly the paragraphs
marked as NOTE, PRECAUTION and DANGER, for your security.
Save the original packing, you can re-use it to transport the unit. NEVER SHIP THE ALTAIR WBS-
200 WITHOUT ITS ORIGINAL PACKING.

3. WORKING PRECAUTIONS
The manufacturer is not responsible of any damage that can possibly happen to the intercom
base station outside the limits of the warranty or those produced by not taking care with the working
precautions.
Mains voltage must be between the limits of the admitted power supply (90-264 VAC, 50-
60 Hz) and that the fuse must be the appropriate (2A slow blow type: T2A). Damage caused
by connection to improper AC 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 intercom base station
is connected to the mains, it carries elements with high voltages. In order to disconnect
the unit completely, you must disconnect it from the mains.
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 intercom base station has been carefully inspected and
tested. 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 mains; notify the sales person 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
INTERCOM MASTER STATION WITHOUT ITS ORIGINAL PACKING.
MOUNTING
It is always recommended to mount the unit in rack, either for mobile or fixed installations, for
protection, safety, aesthetics, etc.
The ALTAIR WBS-200 is designed for standard 19" rack mounting, and takes up 1u high rack
space.
CHANGING THE FUSE
This unit incorporates aninternal, worldwide voltage operation power supply, and it is
prepared to work from 90 to 264 VAC, 50-60Hz.
Make sure that the unit is disconnected from the mains.
In the unit rear panel are placed the mains connector, the mains selector
and the fuse holder. The box bellows this mains connector is called fuse holder.
Take out the fuse holder.

7
WB-200 SERIES INTERCOM SYSTEM — WBS-200 DUAL CHANNEL WIRELESS BASE STATION
After extracting the fuse holder, the fuse will appear, take out it and change for the new one.
Insert the fuse holder into the mains connector again.
Make sure that the fuse is the right one: 2A slow blow type - T2A
CAUTION: Always make sure after changing the fuse, that it is the right one.
CONNECTING TO THE MAINS
The connection of the intercom master station power supply to the mains takes
place by a standard cord included in the box.
Make sure that the unit power switch is at 0 position (turned off).
Insert the female I.E.C. connector of the tripolar cable into the unit power supply
male connector, placed at the rear panel.
Insert the male connector of the tripolar cable into the mains plug.
Turn on the unit power switch. In that moment the CALL
LED indicator will light slightly, indicating that the unit is
turned on.
CAUTION: Make sure that the mains voltage is the correct as well as their fuse is the right one.
ANTENNA MOUNTING
The base station has two antenna connectors (ANT 1 and ANT 2), to mount two antennas
(provided). For optimal performance it is recommended that the two antennas form a 90º angle.
If the base station goes in rack of 19” is important to place the unit in the upper area, to avoid
interferences with the other rack units and the antennas radiate in open space. The best
performance is obtained with the unit to the air without placing it in rack.
In order to increase the operating range of the system you can either install one of the
provided antennas in an upper position or use a high gain directional antenna. See the
accessories section for more information.

PROGRAM INPUT CONNECTION
The intercom base station program input signal is carried out through a XLR-3-31 female
connector. The input connection is balanced, with a nominal impedance of 40 KΩ(20 KΩ
unbalanced). The next list shows the input pins correspondence as A.E.S recommends:
PROGRAM INPUT - XLR-3-31
PIN 1 0 V
PIN 2 HOT (+)
PIN 3 COLD (-)
The input connection depends on two factors, the first is the type of input signal balanced or
unbalanced, and the second the ground configuration of the sound source (floating or ground-
referenced). The next pictures show some of the different possibilities of connection, relying on the
type of input signal, balanced or unbalanced and according to the ground configuration of the
equipment (floating or ground-referenced).
In the next diagrams, we use the following symbols:
Sound source with mains cord without ground connection.
Sound source with mains cord with ground connection.
Sound source with the EARTH-LINK OFF.
Sound source with the EARTH LINK ON.
UNBALANCED INPUT:
This type of connection will be used when the sound source does not provide balanced
output. If it’s possible it is better using the connection type 1.
1) Using twin-lead shielded cable:

PA OUTPUT CONNECTION
The PA output signal is carried out through a XLR-3-32 male connector. The output is
balanced, with a nominal impedance of 100 Ω. The next list shows the input pins correspondence
as A.E.S recommends:
PA OUTPUT - XLR-3-32
PIN 1 0 V
PIN 2 HOT (+)
PIN 3 COLD (-)
The output connection depends on two factors, the first is the type of input signal balanced or
unbalanced, and the second the ground configuration of the sound destination unit (floating or
ground-referenced). The next pictures show some of the different possibilities of connection,
relying on the type of output signal, balanced or unbalanced and according to the equipment’s
ground configuration (floating or ground-referenced).
In the next diagrams, we use the following symbols:
Sound destination unit with mains cord without ground connection.
Sound destination unit with mains cord with ground connection.
Sound destination unit with the EARTH-LINK OFF.
Sound destination unit with the EARTH LINK ON.
UNBALANCED OUTPUT:
This type of connection will be used when the sound destination unit does not provide a
balanced input. If it’s possible it is better using the connection type 1.
