EF-202/EF-204 MASTER STATION – E200 SERIES 3. WORKING PRECAUTIONS The manufacturer is not responsible of any damage that can possibly happen to the intercom 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).
EF-202/EF-204 MASTER STATION – E200 SERIES Make sure that the unit is disconnected from the mains. In the unit rear panel are placed the mains connector and the fuse holder bellow this mains connector is called fuse holder. Take out the fuse holder. 24 . The box 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.
EF-202/EF-204 MASTER STATION – E200 SERIES 9 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).

The output is balanced, with a nominal impedance of 100 Ω. The next list shows the input pins correspondence as A.E.
EF-202/EF-204 MASTER STATION – E200 SERIES 11 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).

Activation is controlled either with the PA function 9 or by the Mic A 11 or Mic B, C and/or D 11 front panel keys.
EF-202/EF-204 MASTER STATION – E200 SERIES EXTERNAL SPEAKER CONNECTION In the master station rear panel is available a connector to plug an external speaker 32 , which allows us to monitor the internal speaker 22 in an external speaker. The external speaker connection is via a 3.5 mm jack connector. The following table shows the correspondence of the connector pins with the external speaker jack 3.5 mm: EXTENAL SPEAKER CONNECTOR SIGNAL WHITOUT CONNECT GND JACK 3/2” TIP RING SLEEVE TIP. RING.

EF-202/EF-204 MASTER STATION – E200 SERIES The next picture shows the habitual connection of an intercom system comprised by eight beltpack units (two per channel) and a EF-204 base station. MULTICHANNEL OPERATION. AUDIO LINKS. Rear panel audio links allows multichannel operation sharing the headset between bases, so accessing all the channels.
EF-202/EF-204 MASTER STATION – E200 SERIES 15 Schematic diagram: System operation is strait forward. You can connect your headset 1 , 2 to any of the bases. Microphone signal from the preamp out of the base #2 is directed to the preamp input in base#1. Channel Mic A,B,C and D 11 on/off switches from base#2 corresponds now to channels E, F, G and H respectively.
EF-202/EF-204 MASTER STATION – E200 SERIES SWITCHES TO GROUND 16 OPEN COLLECTOR The general purpose inputs can control all the buttons on the base station, make a general call to all lines, cause a Mic Kill or enable/disable the Buzzer Kill. By default the base station is configured with input 1 as the PANEL MIC 6 button, and input 2 can cause a general call (simultaneous CALL to CH A, B, C and D). The outputs are open collector, so we can feed to other power circuits provided (50 Volts DC maximum).
EF-202/EF-204 MASTER STATION – E200 SERIES INTERCOM LINE CONNECTIONS – 4W MODE The base station includes 2x (EF-202) / 4x (EF-204) intercom lines. Each line comprises two connectors for gender convenience: one XLR3 male and one XLR3 female internally paralleled. Intercom line is defined as 2 wire mode (2W) enabling direct connection to similar 2W intercom equipments. To connect with 4-wire (4W) equipments, we recommend the use of an Altair 4W2-200 interface per intercom line (channel).
EF-202/EF-204 MASTER STATION – E200 SERIES 18 among all intercom channels. Each channel provides a CALL switch 12 , a MIC on/off switch (TALK) 11 , a LISTEN on/off switch 14 , and a listen level control 15 that allows to listen to the channels independently, or a mix between the channels. The program input allows to insert external audio signals in the intercom system. The external audio signals could be sent to each channel or to the headphones, independently.
EF-202/EF-204 MASTER STATION – E200 SERIES 19 NOTE: Headsets are of the double or single muff type. In case of using a double muff headset, the two speakers should be wired in parallel. HEADSET SIDETONE CONTROL The headset sidetone control 3 adjusts the level of your own voice as you hear it in your headphones. Prior to use the Sidetone control, a good null of the four lines must be done. See next paragraph NULL CONTROL description.
EF-202/EF-204 MASTER STATION – E200 SERIES 20 The remote mic kill switch carries out the function upon pressing it. This means that the units (wired and wireless beltpacks, desk stations units, etc.) connected to the system can switch ON the microphones again when required. When this switch is pressed, its associated LED turns on during a short moment. BUZZER The Buzzer 8 , produces a sound when a call is made, or a key is pressed.
EF-202/EF-204 MASTER STATION – E200 SERIES The TALK switches 11 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.
EF-202/EF-204 MASTER STATION – E200 SERIES 22 MEMORIES The unit has four memories (PRESETS) 16 that allow us to record and retrieve the position of all the switches, so we can return to previously saved settings instantly. We can also save the state of the call, so if when you record a memory, hold down the call switch 12 of the channel which we want to record an active call, when we recall the memory, the system performs a call to the correspondent channel.
EF-202/EF-204 MASTER STATION – E200 SERIES 23 USB PC connection (USB) 25 is made via an USB A MALE / B MALE, allowing you to control all functions of the base stations ALTAIR EF-202 and EF-204. The control software can be downloaded after registration from the ALTAIR website (www.altairaudio.com), and it attached the USB driver for the computer.
EF-202/EF-204 MASTER STATION – E200 SERIES Each intercom line has its own intercom line terminal impedance switch the rear panel of the unit. By default, all the switches must be in Master (M) mode. 34 placed at CAUTION: Never leave the intercom line without terminal impedance, because a bad operation of the units connected to the line would take place. LINK SWITCH The channel link switch (LINK ABCD) 35 , allows to join all the the channels so that the same signal appears in all channels.
EF-202/EF-204 MASTER STATION – E200 SERIES 6. INTERNAL CONFIGURATION SETTINGS SETTING THE PROGRAM INPUT SEND AND THE PROGRAM INTERRUPT The program input send, and the program interruption (program send to the line is interrupt while the microphone (TALK) 17 corresponding to this line is active) can be configured as follows: Hold down the program input switch 17 , for five seconds. At that time the unit will beep and will start blinking the program input LED 17 .
