of functions such as mic active indication,
audio muting during talkback, or audio
insertion control.
Configuration
Model 210 configurations are made
using a number of DIP-type switches. One
8-position switch array is used to set the
gain of the microphone preamplifier, the
on/off status of phantom power, and the
headphone stereo/mono mode. Another
8-position switch array configures which
of the IFB and auxiliary audio sources are
routed to the headphone output. A third
8-position switch array communicates the
desired operating modes to the micropro-
cessor. All switches are accessible via the
bottom of the Model 210’s enclosure; the
unit does not have to be disassembled.
Changes made to any of the configuration
parameters become active immediately.
To prevent unwanted access to the config-
uration switches a security panel, included
with each unit, is attached to the bottom of
the enclosure.
Connectors
The Model 210 uses standard connec-
tors throughout. The microphone and IFB
inputs use 3-pin female XLR connectors.
The main and talkback outputs use 3-pin
male XLRs. A ¼-inch 3-conductor jack
is used for the headphone output. The
external source of 24 volt DC power is
connected by way of a 2.1 x 5.5 mm
“locking” coaxial power jack.
In the world of broadcast and production
audio it’s fair to say that applications vary
widely. To this end, one or two additional
XLR connectors can easily be mounted
into the Model 210’s back panel. Multiple
3-position “headers” located on the Model
210’s circuit board provide technician
access to all input and output connec-
tions. Using a factory-available interface
cable kit allows a Model 210 to be opti-
mized to meet the exact needs of specific
applications. For example, some applica-
tions may prefer to use a multi-pin XLR
connector to interface with a headset.
This can easily be accomplished by add-
ing the appropriate 5-, 6-, or 7-pin XLR
connector and making a few simple con-
nections. Other applications may benefit
from having “mult” or “loop-through” con-
nections, something easily incorporated
into a Model 210. One or two optional line
input cards, as previously discussed, can
also be mounted in the spare XLR connec-
tor positions.
200-Series Announcer
Console Products
The Model 210 is just one in a series of
announcer console products 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 avail-
able on the Studio Technologies website.
Installation and
Setup
In this section interconnections will be
made using the input and output con-
nectors located on the Model 210’s back
panel. Microphone input, IFB input, main
output, and talkback output signals are
interfaced by way of 3-pin XLR connec-
tors. A ¼-inch 3-conductor phone jack is
provided for the headphone output. A 2.1
x 5.5 mm coaxial jack allows connection
of an external 24 volt DC power source.
