Studio Technologies 214 - Manual (Page 10)

Issue 1, July 2014 Model 214 User Guide
Page 10 Studio Technologies, Inc.
Two general-purpose relay contacts are
provided on the Model 214’s circuit board.
Accessible using 3-pin “header” connec-
tors they allow specialized configurations
to be created. Under software control, the
form-A (normally open) solid-state relay
contacts follow the state of the main and
talkback pushbuttons. Taking advantage
of the two locations provided for additional
XLR connectors, a technician may easily
implement a variety of functions such as
a tally indication or audio muting during
talkback.
Future Capabilities &
Firmware Updating
The Model 214 was designed so that its
capabilities can be enhanced in the future.
The primary additions will be in the area
of Dante remote control functionality.
Once an industry-standard has been
established it’s expected that remote con-
trol of microphone preamplifier gain and
microphone phantom power on/off will be
available. Output channel status will also
be able to be reported as well as respond-
ing to status (tally) indications that are
received. These features will allow integra-
tion with devices such as audio consoles,
signals processor units, and matrix inter-
com systems.
A USB connector, located on the Model
214’s back panel, allows the operating
firmware (embedded software) to be up-
dated using a standard USB flash drive.
The Model 214 uses Audinate’s Ultimo™
integrated circuit for implementing Dante.
The integrated circuit’s firmware can be
updated via the Ethernet connection, help-
ing ensure that its capabilities remain up
to date.
Dante-Enabled Announcer
Console Products
The Model 214 is just one in a series of
Dante-enabled announcer console prod-
ucts available from Studio Technologies.
For applications that require an alternate
set of features the other products in the
200-Series should be reviewed. Complete
information is available on the Studio
Technologies website.
Installation
In this section signal interconnections will
be made using the connectors located
on the back panel of the Model 214. A
microphone signal will be interfaced by
way of a 3-pin XLR connector. A ¼-inch
3-conductor phone jack is provided for the
headphone output. An Ethernet data con-
nection will be made using either a stan-
dard RJ45 patch cable or an etherCON
protected RJ45 plug. A 4-pin XLR connec-
tor allows the connection of an external
source of 12 volts DC.
System Components
Included in the shipping carton are the fol-
lowing: Model 214 Announcer’s Console,
user guide, and pushbutton label sheet.
Microphone Input
The Model 214 is compatible with bal-
anced dynamic and condenser micro-
phones. Depending on the application,
the microphone may be part of a headset
or be an independent handheld or stand-
mounted model. The Model 214’s P48
power source will support essentially all
phantom-powered microphones. The

preamplifier and associated circuitry is
