6.0 FRONT PANEL CONTROLS & CONNECTOR
1 LISTEN LEVEL control knobs
These knobs preset the listen level for each
channel separately.
2 TALK buttons
These buttons allow you to talk to each channel
separately or simultaneously.
The large green LED is lit when the talk function for
that channel is activated. Should one talk to a channel
which is in IFB or PAGING mode by pressing and
holding that TALK button, the other lit TALK buttons
will switch off for as long as the IFB / PAGING mode
TALK button is pressed (for further explanation of the
Modes see section 9). To talk to an IFB / PAGING
channel and additionally to a intercom channel, one
should also press and hold the TALK button of the
intercom channel. If in IFB mode and one would like
to talk to all channels of which the TALK LEDs are lit,
than this can be achieved by setting the correspon-
ding, internal dip switch "IFB and TALK" to 'on' (see
8.0 Internal controls / Dip switches).
Latched switching:
When a TALK button is pressed shortly, the
microphone signal is sent to the chosen channel and
the TALK button latches electronically. When pressed
again, the Talk function will switch off.
` Momentary switching:
When holding a TALK button pressed while talking,
the microphone signal will be sent to the chosen
channel until the button is released. Then the talk f
unction will switch off automatically.
3 CALL buttons
These push buttons activate the call system, for each
channel separately.
A momentary push will sent a visual CALL signal to all
stations connected to the intercom channel and the call
LEDS will start flashing. When holding the CALL
buttons for 2 seconds the buzzer will be activated, if
there is no buzzer mute on this channel. After the
CALL button is released the LEDS will continue to flash
for further 2 seconds.
4 TALK to ALL
When the TALK to ALL button is pressed and held,
one will talk to all intercom channels simultaneously
and the green LEDs of all channels will light up -
except for the channels which are in IFB or PAGING
mode. To also include the channels which are in IFB or
PAGING mode, the dip switch IFB and TALK ALL has
to be switched to 'on' (see 8.0 Internal controls / Dip
switches).
5 CALL ALL
When the CALL ALL button is pressed shortly a
visual call signal is sent to all channels and the red
LEDs will start flashing. When holding the CALL
buttons for 2 seconds the buzzer will be activated,
should no buzzer mute be activated for that channel.
After the CALL button is released the LEDs will
continue to flash for further 2 seconds. Channels which
are in IFB or PAGING mode do not receive CALL
signals.
6 MASTER VOLUME
This knob adjusts the volume of the speaker or
headset.
7 STAGE ANNOUNCE
This push button routes the microphone signal
directly to a line level output at the back of the unit.
The microphone signal will not be sent to the intercom
channel even if the TALK LEDs are lit. This can be
changed by setting the corresponding internal dip
switch (STAGE ANN. and TALK) to 'on' (see section
8.0 Internal controls / Dip switches).
The Aux signal can also be routed to the STAGE
ANNOUNCE output by setting the corresponding dip
switch (AUX and STAGE ANN.) to 'on' (see section
8.0). In EXTENDED Mode only the microphone signal
of the Master unit will be routed to the STAGE
ANNOUNCE output of the master. This can be
changed by setting the corresponding dip switch
(Stage announce mic. Select) to 'on'(see section 8.0) in
which case each unit will use its own Stage Announce
output and microphone.
