NOTE: Headphones could be with a double or single muff. In case of using a double muff
headphone, the two speakers should be wired in parallel mode.
3.2 MIC ON/OFF/PUSH TO TALK SWITCH (TALK)
The MIC switch allows to enable/disable the
microphone, so that we are able to speak with other
units connected to the same intercom channel.
If the microphone is activated, its associated LED will light up and this icon, will show in the
display: ,and on the other hand, if it is disabled, its associated LED will turn off and will not
show the icon in the display.
The MIC switch has two operation modes. When this switch is pressed quickly the microphone
changes its state, if it was enabled, upon being pressed it gets disabled and turns off the
associated LED, and if it was disabled, upon being pressed gets enabled and turns on the
associated LED.
When the MIC switch is pressed and held, the unit will enter in the special function PUSH TO
TALK, this means that the microphone will be enabled until the switch is released.
The unit provides a MIC-KILL (turns off the MIC) system, so that when the mic is enabled it is
possible to muted it by the MIC-KILL function of the base station ALTAIR WBP-200 or a master station
EF-200, connected to the base station. This MIC-KILL system is compatible with other intercom
systems of the market.
The state of the MIC (on/off), it is stored in the unit.
3.3 CHANNEL SELECTION SWITCHES
The main function of this switch is to select the
operation channel you want to communicate.
Selected channel is indicated on the indicator lamps A/B and the
OLED Display: . Pressing this switch, if it was selected, deselected and vice versa, with the
condition that should always be selected a channel (A or B, or both at the same time), so if you only
have selected A and press A, not deselect as always should be selected at least one channel.
Channel selection affects the beltpack functions as described:
MIC: The beltpack mic signal is feed to the selected channel indicated by the lamps. You can adjust
your mic level by menu or by pressing the mic switch and change its gain with the up-down
arrows.
LISTENING The listening channel depends also of the selected channel indicated by the lamps and
by the OLED display: . By selecting AB, you can listen both channels simultaneously. A balance
listening between channels is allowed in each of the 3 possible selections A, AB and B. By using
this balance, you can listening the opposite channel at a small, say 20 % level, helping
management of both channel crews at a time.
CALL The sending Call channel is the indicated on the lamps and in the OLED display. When AB is
selected, a Call is sent to both channels. The receiving channel Call is also shown on the AB lamps
by flashing accordingly. As the selected channel is obviously not automated, you must go to that
channel if you are in the opposite channel in order to communicate with him.
3.4 STAGE ANOUNCE (SA) KEY
