MODEL 204
ANNOUNCER’S CONSOLE
and headphones or earbud should have
been connected. Alternately, a broadcast-
style headset may have been connected.
If desired, a connection to the microphone
output should have been made. Some ap-
plications may utilize either or both of the
remote control inputs.
The Model 204 should have been placed
in the desired physical location. Using the
Studio Technologies STcontroller software
application the unit’s configuration should
have been selected to meet the needs of
the specific application. The Model 204’s
Dante configuration settings should have
been selected using the Dante Controller
software application. In this way the unit’s
two Dante audio output channels (Dante
transmitter channels) and four Dante audio
input channels (Dante receiver channels)
should have been routed, by way of Dante
“subscriptions,” to the receiver and trans-
mitter channels on associated Dante-
enabled equipment.
Initial Operation
The Model 204 will start to function as soon
as a Power-over-Ethernet (PoE) power
source is connected. However, it may take
20 to 30 seconds for full operation to com-
mence. Upon initial power up the three
status LEDs, located on the back panel
below the RJ45 jack, will begin to light as
network and Dante connections are estab-
lished. The COMP LED, adjacent to the
microphone input connector, may or may
not flash momentarily. The P48 LED, also
located adjacent to the microphone input
connector, will flash once to indicate that
it is functioning. The red and green LEDs
within the main and talkback pushbutton
switches will light in a short test sequence
to indicate that the application firmware
(embedded software) has started. Once
acoustical feedback will occur in applica-
tions where the headphone output is con-
nected to the inputs on amplified speakers
(or inputs on an amplifier associated with
loudspeakers). In this mode the level of the
headphone output channels is reduced by
18 dB whenever a main or talkback func-
tion is active. This mode is not appropriate
when headphones are going to be connect-
ed to the Model 204!
Remote Control Inputs
There are two remote control inputs. They
can be individually configured to mimic the
action of one of the pushbutton switches.
The choices are off, main button, or talk-
back button.
Button Backlight Intensity
The caps (top surfaces) of the two pushbut-
ton switches are able to be lit using internal
LEDs, one red and one green. When they
light and with what color depends on the
configuration of the Model 204 and the
current operating condition. The intensity
of these LEDs can be adjusted to meet the
needs of an application, specifically being
configured to perform optimally vis-à-vis
the amount of ambient light present in the
Model 204’s location. The choices are low
and high.
Operation
At this point all connections and configura-
tion steps should have been completed and
everything should be ready for Model 204
operation to commence. An Ethernet con-
nection with Power-over-Ethernet (PoE)
capability should have been made. Alter-
nately, a midspan power injector, in “se-
ries” with the Ethernet connection, should
have been put into place. A microphone
