1. I N TRO D U CTI O N
Co ng r a tu la ti on s on yo ur p ur ch a se of th e ALTAIR dual channel master station EF- 2 0 0 of the
E- 2 0 0 series intercom system. There is a lot the characteristics that make of the ALTAIR E- 20 0 series
one of the most highlighted in the audio professional market, some are enumerated here:
The new ALTAIRE-200 SERIESadd more features to our popular Espiral E-100 series, maintaining
compatibility. All the components in the system incorporate a microcontroller to implement different
tasks as Mic Killer, Remote all Buzzer switch-off, Mic Switch Latch or Push To Talk, Program Interrupt,
etc.
Re m o t e A l l M i c s w i t c h - o f f h e l p s t h e o p e r a t o r t o m a i n t a i n a l o w e r n o i s e c o n v e r s a t i o n i n n o i s y
environments. Also implemented is the remote All Buzzers switch-off feature to avoid undesired
audible CALLsignalling during performances.
Th e M a s t e r St a t i o n u n i t p o w e r s a l l t h e Sys t e m c o m p o n e n t s a n d i n c o r p o r a t e s n e w sp e c i a l f e a t u r e s
as System Expandability or Battery Operation.
System Expandability permits creating a multichannel (4, 6, or more channels) Intercom System by
using more Master Stations in a daisy chain arrangement. This feature enables freedom in the System
design and in-site future upgrades. Rental companies can benefit with lower component inventories.
Our new internal Battery operation permits short-time communications in difficult situations (= no
Po w er ) o f em er g en cy.
The ALTAIREF-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.
Befo r e b eg in nin g i t i s im p o r ta n t to r ea d this m a n ua l . Th is m a n ua l w i ll help you to i nsta l l a n d u se
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.

3. WORKING PRECAUTIONS
Th e m a n u f a c t u r e r i s n o t r e s p o n s i b l e o f a n y d a m a g e t h a t c a n p o s s i b l y h a p p e n t o t h e i n t e r co m
master 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 master
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
Beforeleavingthefactory,eachintercommasterstationhasbeencarefullyinspectedand
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 salesperson immediately;
a qualified service technician should inspect the unit.
Savetheoriginalpacking,youcoulduseifyouneedtotransporttheunit.NEVER SHIP THE
INTERCOM MASTER STATION WITHOUT ITS ORIGINAL PACKING.

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 bellow this mains connector is called fuse holder.
Ta k e o u t t h e f u s e h o l d e r .
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.

allows the system operation in no power difficult situations during a short period of time. The use of
alkaline batteries is recommended.
Make sure that the unit power switch is at 0 position (turned
off).
In the unit rear panel is placed the battery holder. Take out
the battery holder, pushing up and toward you with a coin
Insert the battery into the battery holder, taking into account
the polarity that comes indicated inside the battery holder.
Insert the battery holder into its rear panel plastic box.
NOTE: The battery power has an internal fuse, located inside the unit, in order to protect the unit of
excessive currents in the battery. If it is necessary to change the fuse, make sure that the device is
disconnected from the mains, and open the top cover according to the indications of the section
special operations. The fuse is placed in the top right corner, just beside the battery holder. After
changing make sure that it is the adequate T1A (1ampere, slow blow type).
