The application is available for download
on the Studio Technologies website
(www.studio-tech.com). Its initial release
is compatible with the Windows® operat-
ing system. Changes made using the ap-
plication will be displayed in real-time on
the Model 216’s 2-digit display. Changes
made to the mic pre gain and P48 on/off
status using the Model 216’s pushbutton
switches will be displayed in STcontroller.
LED Display Time-Out
The 2-digit LED display provides an in-
dication of the headphone output gain
range, the gain of the microphone pre-
amplifier as well as the on/off status of
P48 phantom power. As a power-saving
measure the display will automatically
stop lighting approximately 100 seconds
after the last time that either of the bot-
tom pushbutton switches is pressed. A
different time-out interval applies after the
Model 216 has had power applied and
neither pushbutton is pressed; the display
will light for approximately 10 seconds and
then turn off.
In most cases this display auto-off function
will lead a technician or installer to initially
observe that the 2-digit display is not light-
ing. For example, a Model 216 has been
operating normally but the security panel
has just been removed. To cause the
2-digit display to again light just requires
pressing either of the bottom pushbutton
switches. This “wakes up” the display and
resets the timer. The initial press of either
pushbutton will not cause the gain to
change or impact the P48 phantom power
on/off status. Only when the 2-digit display
is active will the pushbuttons impact the
settings.

Operating Modes
Twelve DIP switches are used to configure
the Model 216’s operating modes. Techni-
cally, these switches “talk” to a micro-
controller integrated circuit and associ-
ated software that give the Model 216 its
“smarts.” The software has been carefully
designed to provide a number of different
ways in which the unit can function. It’s
important to carefully review the available
options and choose the ones that best
meet the needs of a specific application.
Note that the switches can be changed
even while the Model 216 is powered up
and operating. The unit’s operating char-
acteristics will change in real-time in re-
sponse to switch changes.
Main Button Mode
Switches 1 and 2 configure how the main
pushbutton functions.
There are four available modes:
• Push to Mute: In this mode the audio
signal on the main output channel
is normally active. The audio signal
will mute whenever the pushbutton is
pressed and held. This is the “cough”
mode typically used for on-air sports
broadcasting applications.
