INTERCOM STATION
function is active then audio from the selected
microphone source will be connected to the
associated Dante output channel. The LED in
the pushbutton switch will light green when-
ever the function is active. When the push-
button is not pressed nor currently active no
audio will be present on the associated Dante
output channel. The associated Dante IFB
program input channel will not be utilized.
Talk with 18 kHz Tone
When a button function has been configured
for Talk with 18 kHz Tone and the pushbutton
is pressed or the function is active then audio
from the selected microphone source, mixed
with an 18 kHz sine wave tone at a level of
–20 dBFS, will be connected to the associ-
ated Dante output channel. The LED in the
pushbutton switch will light green whenever
the function is active. When the pushbutton is
not pressed nor the function is active no audio
(voice or tone) will be present on the associ-
ated Dante output channel. The associated
Dante IFB program input channel will not be
utilized.
All Talk
When a button function has been configured
for All Talk and the pushbutton is pressed or
the function is active then all other buttons
that are configured for Talk or Talk with 18
kHz will become active. The LED in the push-
buttons configured for All Talk will light green
whenever the function is active. The associ-
ated Dante output channel will not be utilized,
nor will the associated Dante IFB program
input channel.
Call
When a button function has been configured
for Call and the pushbutton is pressed or the
function is active then all other pushbuttons
that are both configured for Talk or Talk with
18 kHz and are active will have a 20 kHz sine
wave tone at a level of –20 dBFS added to
their associated Dante output channels. The
LED in the pushbutton configured for Call
will light orange whenever the function is ac-
tive. The buttons that are configured for Talk
or Talk with 18 kHz that are active will flash
orange. The associated Dante output chan-
nel will not be utilized, nor will the associated
Dante IFB program input channel.
IFB
When a button function has been configured
for IFB a broadcast-type interrupted foldback
(IFB), also referred to an interruptible foldback
or a talent cue signal, will be created. When
the pushbutton is not pressed or active the
associated Dante IFB program input source
will be connected to the associated Dante
output channel. The Dante IFB program input
source is connected to the Dante output
channel at unity level (no gain or attenua-
tion will be applied to the signal). When the
pushbutton is pressed or the function is ac-
tive then two things will occur. The first is that
the Dante IFB program input source will be
acted on following the configuration for the
IFB program dim value. This will result in the
signal level either staying the same, dropping
in level (being attenuated) by one of four val-
ues, or completely muting. The second action
is that the selected microphone source will be
added (summed) with the Dante IFB program
input source and then routed to the associ-
ated Dante output channel. The pushbutton
will light green when the function is active.
The IFB function creates a talent cueing
signal that is sometimes referred to as Inter-
rupt, Program with Interrupt, or Program +
Interrupt. The selected microphone source
(headset or gooseneck) serves as the inter-
rupt source. The Dante IFB program input
signal is considered to be the program audio
source. Note that there is no means provided
within the Model 348 to adjust the level of the
IFB program input source. This should not be
