Model 354
TALK STATION
Preamble Audio Only (Play Once, Interruptible):
In this mode when the channel’s pushbutton switch
becomes active the selected preamble audio file will
play once and then stop. Changing the pushbutton
switch to its inactive state when the preamble audio
file is actively playing will cause it to immediately stop.
Microphone audio will never become active.
Preamble Audio Only (Play Once, Complete): In
this mode when the channel’s pushbutton switch
becomes active the selected preamble audio file will
play once and then stop. Changing the pushbutton
switch to its inactive state when the preamble audio
file is actively playing will not cause it to stop. The
preamble audio file will always completely play once.
Microphone audio will never become active.
Preamble Audio Only (Play Continuous, Interrupt
-
ible): In this mode when the channel’s pushbutton
switch becomes active the selected preamble audio
file will play continuously. Changing the pushbutton
switch to its inactive state when the preamble audio
file is actively playing will cause it to immediately
stop.
Pr eam bl e A udi o On ly ( Pla y C on t in uou s,
Complete): In this mode when the channel’s push-
button switch becomes active the selected preamble
audio file will play continuously. Changing the push-
button switch to its inactive state when the preamble
audio file is actively playing will not cause it to imme-
diately stop. The preamble audio file will play until it
ends and then stop.
Preamble Audio Source
Choices are: File 1, File 2
The Model 354 can store and play two independent
audio (WAV) files. These are called preamble audio
files and are loaded using a USB flash drive. This con
-
figuration selection determines which of the two files is
assigned to a specific pushbutton switch function.
Program Audio Source
Choices are: None, Ch 1, Ch 2, Ch 3, Ch 4
This selection determines which of the Dante receiver
(input) channels is used as the program audio source
for its associated Dante transmitter (output) channel.
For a typical voice paging system application this
configuration determines which audio signal would
be sent to a paging zone as the background music
source. For broadcast applications where talent cue
(interrupted foldback or IFB) signals need to be cre-
ated this setting would determine the IFB program
audio source.
A separate configuration setting determines the
amount of attenuation that will be applied to the pro
-
gram audio source when the preamble or microphone
audio is active. For some applications it’s possible
that a program audio source will not be assigned to
a Dante transmitter (output) channel. In this situation,
the selection of None would be correct.
Program Audio Dim
Choices are: 0 dB, 5 dB, 10 dB, 15 dB, 20 dB,
Full Mute
This value determines the amount of attenuation that
will be applied to the selected program audio source
when the preamble audio or microphone audio is
active on the Dante transmitter (output) channel.
Selecting 0 dB will configure the channel to have no
change in program audio level when the preamble or
microphone function is active. The preamble and/or
microphone audio will simply be combined (added or
summed) with the program audio. When Full Mute is
selected the program audio source will fully attenu
-
ate (completely mute) whenever the preamble and/or
microphone audio is active. In voice paging applica-
tions it would be typical to select 5 dB or 10 dB for
the program audio dim, reducing but not muting a
background music source. In most broadcast appli-
cations where a talent cue (interrupt or IFB function)
signal is going to be created a value of 15 dB would
be appropriate.
Channel Status Signal
Choices are:
None
18 kHz Tone when Preamble or Mic Active
20 kHz Tone when Preamble or Mic Active
20 kHz when Inactive, 18 kHz when Preamble
or Mic Active
20 kHz when Receiver Channel Active, None when
Preamble or Mic Active
16 kHz when Receiver Channel Inactive, 20 kHz
when Receiver Channel Active, 18 kHz when
Preamble or Mic Active
The Model 354 can be configured to support a number
of interesting applications through the generation of
