Model 214A
ANNOUNCER’S CONSOLE
Push to Talk/Tap to Latch:
This mode is a combination of the
Push to Talk and Latching modes. It’s similar to the way talk
pushbutton switches function on user stations associated
with broadcast or production intercom systems. If the main
button is pressed and held the main button’s function will be
active. It will stay active until the main button is released. If
the main button is momentarily “tapped” the main button’s
status will change, either from inactive-to-active or from
active-to-inactive. Upon Model 214A power up the main
button function will be in its inactive state.
Push to Mute/Tap to Latch:
This mode is a combination of
the Push to Mute and Latching modes. Whenever the main
button is momentarily “tapped” the main button’s status
will change, either from active-to-inactive or inactive-to-
active. The audio signal associated with the output of the
microphone pre-amplifier will be routed to the Dante main
transmitter (output) channel. Whenever the main button is
pressed and held this audio signal will not be present on
the Dante main transmitter (output) channel. It will stay
in this condition until the main button is released. Upon
Model 214A power up the main button function will be in
its inactive state.
Button Operation – Talkback
Choices are
Push to Talk
,
Latching
, and
Push to Talk/
Tap to Latch
.
The manner in which the talkback pushbutton switch func-
tions can be configured. There are three mode choices
available.
Push to Talk:
If this mode is selected, the talkback function
will normally be inactive and the LED associated with the
talkback button will not be lit. Whenever the talkback button
is pressed the talkback function will become active and
depending on the unit’s configuration, the button’s green
or red LED will light.
Latching:
If this mode is selected, the talkback function will
alternate between the active and inactive states whenever
the talkback button is pressed. Upon power up the talkback
function will be in its inactive state and its button LED will
not be lit.
Push to Talk/Tap to Latch:
This mode is a combination of
the Push to Talk and Latching modes. It’s similar to the way
talk pushbutton switches function on user stations associ-
ated with broadcast or production intercom systems. If the
talkback button is pressed and held the talkback function
will be active. It will stay active until the talkback button is
released. If the talkback button is momentarily “tapped”
the status of the talkback function will change, either from
inactive-to-active or from active-to-inactive. Upon Model
214A power up the talkback button will be in its inactive
state and its LED will not be lit.
System – Operating Mode
Choices are
On-Air
,
Production
, and
Production with Dim
.
The operating mode configures the overall manner in which
the Model 214A operates. Specifically, it determines how
the Dante main transmitter (output) channel operates vis-
à-vis the Dante talkback transmitter (output) channel and
whether the headphone output level is reduced during
talkback operation. Understanding how these three modes
impact overall system operation will ensure that correct
operation and maximum usability will occur.
On-Air:
When selected to the on-air mode, the audio signal
on the Dante main transmitter (output) channel will mute
whenever the Dante talkback transmitter (output) channel
is active. The on-air mode should be selected for all on-air
broadcast applications when it’s imperative that the audio
signal on the Dante main transmitter (output) channel be
muted whenever on-air talent uses the talkback function
to communicate with production personnel.
Production:
When the system mode is set for production,
the audio signal on the Dante main transmitter (output)
channel won’t mute in response to the talkback function
being active. This mode allows the Dante main transmitter
(output) channel to be used, for example, as an additional
Dante talkback transmitter (output). In this way, the Dante
main and talkback transmitter (output) channels can be
used independently, with neither impacting the other. This
also allows the two pushbutton switches and their associ-
ated functions to be used simultaneously. When selected
for the correct application, this mode can prove to be very
useful. However, it’s not appropriate for on-air use!
Production with Dim:
This mode is identical to the produc-
tion mode with the exception that the headphone output
will reduce in level (“dim”) whenever the main or talkback
functions are active. This mode was specifically provided
to minimize the chance that acoustical feedback will occur
in applications where the headphone output is connected
to inputs on audio amplifiers or amplified speakers. In
this mode, the level of the headphone output channels is
reduced by 18 dB whenever the main or talkback function
is active. This mode is not appropriate when headphones
are going to be connected to the Model 214A!
System – Button Backlight Intensity
Choices are
High
and
Low
.
This configuration choice selects the intensity of the white
LEDs that provide backlighting for the two pushbutton
switches. Two choices are available: low and high.
Low
is
appropriate when the Model 214A is to be used in an envi-
ronment where the ambient light level is low.
High
would be
appropriate where other light sources in the physical area
