1. INTRODUCTION
Co gratulatio s o your purchase of the ALTAIR master statio EF-202/EF-204 of the
E-200 series i tercom system. There is a lot the characteristics that make of the ALTAIR E-200
series o e of the most highlighted i the audio professio al market, some are e umerated here:
The Master statio u it i cludes the power supply for all the i tercom compo e ts i the
system. I the case of short circuit o a y poi t of the li e, the u it shuts dow with a
i sta ta eous recovery after the fix is cleared. System ca drive up to 60 si gle cha el
beltpacks or 20 desk statio s.
Separated four cha els are provided with i depe de t Talk, Liste , a d Call sig alli g
butto s. Li ki g betwee cha els is made easy from the fro t pa el butto s.
All the compo e ts i the system i corporates digital co trol to impleme t differe t task
as Mic Kill, remote buzzer switch-off, latch or PTT mic switchi g, etc.
The statio i corporates program i put (mic/li e) with level atte uator assig able to a y
of the four cha els a d mic output to address PA messages from the headset operator.
Relay co tacts are provided that follows the PA butto actio , helpi g the i staller to
automate multiple tasks as Tally, speaker switchi g a d cue lights amo g others. The
statio ca be used as a Mai statio drivi g all the system or as a desk remote co sole
statio i complex multipoi t multicha el i stallatio s.
O e block of four key butto s allows the u it to be preset for i sta t recall of programmed
set-up i cludi g Talk, Liste a d Call key fu ctio s to a y cha el combi atio i a
i tuitive ma er.
Fro t pa el i cludes goose eck pa el micropho e, headset co ectio a d a high
efficie cy speaker.
Before begi i g it is importa t to read this ma ual. This ma ual will help you to i stall a d
use your ew i tercom master statio . It is very importa t to read it carefully, mai ly the
paragraphs marked as NOTE, PRECAUTION a d DANGER, for your security.
Save the origi al packi g, you ca re-use it to tra sport the u it. NEVER SHIP THE
ALTAIR EF-202/EF-204 WITHOUT ITS ORIGINAL PACKING.

. WORKING PRECAUTIONS
The ma ufacturer is ot respo sible of a y damage that ca possibly happe to the
i tercom master statio outside the limits of the warra ty or those produced by ot taki g care
with the worki g precautio s.
Mai s voltage must be betwee the limits of the admitted power supply (90-264
VAC, 50-60 Hz) a d that the fuse must be the appropriate (2A slow blow type: T2A).
Damage caused by co ectio to improper AC voltage is ot covered by a y warra ty.
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 ot place the u it close to heat sources.
4. INSTALLATION
UNPACKING
Before leavi g the factory, each i tercom master statio has bee carefully i spected
a d tested. U pack a d i spect the u it for a y damage that may have occurred duri g
shipme t. If a y damage is fou d, does ot co ect the u it to the mai s; otify the
salesperso immediately; a qualified service tech icia should i spect the u it.
Save the origi al packi g, you could use if you eed to tra sport the u it. NEVER SHIP
THE INTERCOM MASTER STATION WITHOUT ITS ORIGINAL PACKING.
MOUNTING
It is always recomme ded to mou t the u it i rack, either for mobile or fixed
i stallatio s, for protectio , safety, aesthetics, etc.
The ALTAIR EF-202/EF-204 is desig ed for sta dard 19" rack mou ti g, a d takes up
1u high rack space.
CHANGING THE FUSE
This u it i corporates a i ter al, worldwide voltage operatio power supply, a d it is
prepared to work from 90 to 264 VAC, 50-60Hz.

bellow this mai s co ector is called fuse holder. Take out the fuse holder.
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: lways make sure after changing the fuse, that it is the right one.
CONNECTING TO THE MAINS

Certai rules have to be followed whe i stalli g the cables of a i tercom system.
This is to avoid grou d loops a d to mi imize the power loss a d possible effect of
electromag etic fields.
Do ot co ect the XLR pi 1 to the XLR metal housi g or to metal wall boxes to
avoid grou d loops. The grou d loop could i crease otably the system backgrou d
oise.
Do ot close the i tercom li e co ectio (avoid closed loops). Each i tercom li e
leaves from the base statio towards the remote statio s, but it does ot retur to the
master statio . If the co ectio is closed, a grou d loop with the i crease from the
system oise will take place.
Use high quality cables a d mi imize its lo gitude. Avoid usi g low quality cables

base statio is co figured with i put 1 as the PANEL MIC butto , a d i put 2 ca cause
a ge eral call (simulta eous CALL to CH A, B, C a d D).
The outputs are ope collector, so we ca feed to other power circuits provided (50
Volts DC maximum). I the output co ector is available a supply of 5 volts DC to power the
ope collector circuit, this power is limited to 100 mA. The outputs ca be co ected to
LEDs i dicators, DC relays, amo g others.
