TALENT CONSOLE
control. The display consists of eight bi-color LEDs
that can individually light green, red, or orange. This
configuration setting selects when the multi-purpose
display will provide a real-time display of the output
level of the Model 209’s microphone preamplifier.
When acting as a level meter the five LEDs on the
left will progressively light green to indicate a normal
signal level. The next two LEDs, the sixth and sev-
enth, will light orange to indicate that the signal level is
greater than nominal. The eighth LED, on the far-right
end, will light red when the microphone preamplifier’s
output level is approaching or has reached its maxi-
mum. The action of the level meter can serve as a
user-confidence indication or as a guide when adjust-
ing the gain of the microphone preamplifier.
The selected configuration choice will depend on the
needs of the unit’s application. When selected for Off
the display will never show the level associated with
the output of the microphone preamplifier. When se
-
lected for Always On, the display will indicate the level
of the output of the microphone preamplifier, no mat-
ter the on or off state of the Dante main and talkback
transmitter (output) channels. When selected for On
When Main Active, the level meter will be active only
when microphone audio is being sent to the Dante
main transmitter (output) channel.
It’s possible that the level display will only be enabled
during setup and testing of an application. After per
-
formance confirmation, including adjusting the gain of
the microphone preamplifier, users may request that
the microphone level display function be turned off.
Tally Outputs – Configuration
Configuration – Output 1 Source
Choices are STcontroller On/Off Button, Main Output
Active, GPI 1, GPI 2, TOX – Headphone Ch1, and
TOX – Headphone Ch2.
The state (active or inactive) of Tally Output 1 can be
controlled by the configuration selected from among
the six available sources.
STcontroller On/Off Button: When this source is
selected the state of Tally Output 1 will be controlled
by the virtual pushbutton switch that’s present on
STcontroller’s Tally Output configuration page. Using
a mouse to click the On/Off button icon will cause the
state of Tally Output 1 to change. This function can
be useful during installation and configuration of the
Model 209 and related signals. It can also be used
as a means for an STcontroller user or associate to
control the state of Tally Output 1.
Main Output Active: When this source is selected
the state of Tally Output 1 will be controlled by the
state of the Dante main transmitter (output) channel;
Tally Output 1 will be active when microphone audio
is present on the Dante main transmitter (output)
channel. This can be used as a locally controlled
“on-air” indication.
GPI 1: When GPI 1 is selected the state of Tally
Output 1 will be controlled by the state of the remote
control input that is named GPI 1. Tally Output 1 will
be inactive when GPI 1 is not active. Tally Output 1
will be active when GPI 1 is in its enabled (low or
input shorted) state. This configuration choice can
be useful when an external signal, such as an on-
air contact closure from an automation system or
audio console, needs to control the on/off state of
Tally Output 1. In this way, an LED, typically associ
-
ated with a microphone boom arm, can be directly
activated by a contact closure; no external interface
would be required.
GPI 2: This choice is similar to GPI 1 except Tally
Output 1 responds to the state of GPI 2. This is pro
-
vided for control flexibility.
TOX – Headphone Ch1: This choice allows a high-
frequency signal present on the Dante receiver (input)
channel Headphone Ch1 to control the state of Tally
Output 1. The acronym TOX has traditionally meant
“Tone Operated Relay.” In the case of the Model 209 it
means that a high-frequency tone (typically 18 kHz or
above) can be added “in-band” to the Dante receiver
(input) channel and is used as a control signal. When
a signal that meets the requirements for level and
frequency is present on the Dante receiver (input)
Headphone Ch1 then Tally Output 1 will become ac
-
tive. This is provided so that an audio channel can
provide both talent cue audio information along with a
“trigger” for Tally Output 1. (Refer to the specifications
section of this guide for details on what constitutes
a valid.)
Having talent audio combined with a high-frequency
tone is typically not a problem as the Model 209
includes a low-pass filter in the headphone output
