Phantom Power On/Off
The Model 216 can provide P48 (48 volt
DC nominal) phantom power to the con-
nected microphone. The two pushbutton
switches control whether or not phantom
power is active. Pressing both pushbut-
tons simultaneously will toggle (change)
the on/off state. The decimal point indica-
tor, located on the lower right corner of
the 2-digit LED display, is used to show
the phantom power on/off status. When
the decimal point is lit phantom power is
enabled. By the very nature of phantom
power it should be able to be left enabled
at all times. But generally people prefer
to turn it off unless required for a specific
microphone.
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
response 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.
• Push to Talk: In this mode the audio
signal on the main output channel is
normally muted. The main audio signal
will become active whenever the push-
button is pressed and held.
• Latching: In this mode the audio signal
on the main output channel will change
between its active and muted states
whenever the pushbutton is pressed.
Upon power up the audio signal on the
main output will be in its muted state.
• Hybrid: This mode is a combination
of push to talk and latching action. It’s
similar to the way talk pushbuttons
function on user stations associated
with broadcast and production intercom
systems. If the pushbutton is pressed
and held, the audio signal on the main
