Studio Technologies 216 - Manual (Page 20)

Issue 1, July 2014 Model 216 User Guide
Page 20 Studio Technologies, Inc.
The Model 216 will support audio sample
rates of 44.1 kHz or 48 kHz with the ability
to select pull-up/pull-down values. These
parameters can be selected using the
Dante Controller application but in most
applications 48 kHz will be appropriate.
The Model 216 can serve as the clock
master for a Dante network but in most
cases that would not be optimal.
Operation
At this point the audio, Ethernet, and pow-
er connections should have been made.
The pushbutton labels may have been
revised. The desired configuration should
have be made using the pushbutton and
DIP switches. The Dante input (receiver)
and output (transmitter) channels should
have been routed using the Dante Control-
ler software application. Normal operation
of the Model 216 can now begin.
Initial Operation
The Model 216 will begin functioning a
few seconds after its power source is
connected. As previously discussed, the
power source can be provided by Power-
over-Ethernet (PoE) or an external source
of 12 volts DC. If both are connected the
PoE source will power the unit. Should
PoE subsequently no longer be available
uninterrupted operation will continue using
the external source.
Upon Model 216 power up most of the
status and backlight LEDs along with the
2-digit display will activate in a test se-
quence. The PoE, USB, and SIG/PEAK
LEDs, located on the back panel, will light
one after another. On the top surface of
the Model 216 the two status LEDs and
the backlight LED associated with the
main pushbutton switch and the status
LED and the backlight LEDs associated
with the talkback pushbutton switches will
momentarily light in sequence. Once that
sequence has completed all the LEDs will
begin to function normally.
The 2-digit LED display is visible on the
bottom of the unit when the security panel
is removed. Upon unit power up, all seg-
ments of each display digit will light briefly
as a confirmation that they are functioning.
Then the version number of the operat-
ing firmware (embedded software) will
briefly display. For example, the first firm-
ware version shipped with the Model 216
would display 1.0. Then the gain of the
microphone preamplifier (in dB) and the
phantom power on/off status will display
and remain active. Unless either or both
the gain/phantom pushbutton switches are
pressed, approximately 10 seconds after
the unit begins operation the display will
stop lighting. This is a power saving mea-
sure. The display will again light after either
or both of the pushbuttons are pressed.
Note that the way in which the LINK/ACT,
SYS, and SYNC LEDs (all located below
the Ethernet connector) will light depends
on characteristics related to the connected
Ethernet signal and the configuration of the
unit’s Dante interface. This will be covered
in detail in the next section of this guide.
After the power-up sequence has com-
pleted the Model 216 will begin normal
operation. Depending on the selected
configuration, one status LED associated
with the main pushbutton switch may be lit.
The user is now presented with four push-
button switches, five LEDs, and three rotary
controls. These are simple to operate and
understand, as will be described in later
paragraphs.
