Additional Connector Locations
In the world of broadcast and production
audio it’s fair to say that applications vary
widely. To this end, up to three additional
XLR connectors can be easily mounted
into the Model 220’s back panel. Multiple
3-position “headers” located on the Model
220’s circuit board provide technician-
access to literally every input and output
connection. Using a factory-available inter-
face cable kit, these allow a Model 220 to
be optimized to meet the exact needs of
specific applications. For example, some
applications may prefer to use a multi-
pin XLR connector to interface with a
headset. This could be easily accom-
plished by adding the appropriate 5-, 6-,
or 7-pin XLR connector and making a few
simple connections. Other applications
may benefit from having “mult” or “loop-
through” connections, something easily
incorporated into a Model 220.
Multi-Pin Headset Connectors
As previously mentioned, some broadcast
applications use headsets that interface
using a multi-pin connector. In most cases
these connectors are 6- or 7-pin male
XLRs wired to an industry-standard pinout
scheme. Studio Technologies offers head-
set connector assemblies that allow fast
and painless installation into a spare con-
nector location in the Model 220’s back
panel. Details about these optional assem-
blies are available on the Studio Technolo-
gies website.
Options
The Model 220’s standard resources are
more than sufficient to directly support a
large number of applications. But in the
“real world” of audio and intercommunica-
tions special needs always seem to arise.
To that end, Studio Technologies offers a
number of option cards. In addition to pas-
sive or active components, each card con-
tains an integral connector, allowing simple
installation into a spare connector location
on the Model 220’s back panel. For interest,
the resources provided by some of these
option cards are worth describing.
• The direct microphone output card
provides access to the dynamic or con-
denser microphone that is connected to
the Model 220’s mic input. Passive com-
ponents, along with the auxiliary relay
contact, create a “click-free” microphone-
level audio signal.
• The remote switch input card uses a 4-pin
XLR connector to provide access to the
Model 220’s remote switch inputs.
• The tally/remote switch input card pro-
vides a current-limited DC voltage that
serves as a main output status signal.
It also provides a remote switch input
connection.
Other general purpose option cards provide
3-pin XLR, 4-pin XLR, and 8-pin EtherCon®
connectors. With the range of option cards
available it’s hard to imagine an application
that can’t be served. But you’re welcome
to try to “stump the chumps” in the Studio
Technologies technical support department!
But first please check the complete list of
the available option cards listed on the
Studio Technologies website.
200-Series Announcer Console
Products
The Model 220 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 available
