XLRs. The headphone output utilizes a
¼-inch 3-conductor jack. The external
source of 24 volt DC power is connected
by way of a 2.1 x 5.5 mm “locking” coaxial
power jack.
Additional Connector Locations
In the world of broadcast and produc-
tion audio it’s fair to say that applications
vary widely. To this end, up to three addi-
tional XLR-type connectors can be easily
mounted into the Model 230’s back panel.
Multiple 3-position “headers” located on
the Model 230’s circuit board provide
technician-access to literally every input
and output connection. Using a factory-
available interface cable kit, these allow
a Model 230 to be optimized to meet the
exact needs of specific applications. For
example, some applications may prefer
to use a multi-pin XLR-type connector to
interface with a headset. This could be
easily accomplished by adding the appro-
priate 5-, 6-, or 7-pin XLR-type connector
and making a few simple connections.
Other applications may benefit from hav-
ing “mult” or “loop-through” connections,
something easily incorporated into a
Model 230.
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
XLR-type wired to an industry-standard
pin out scheme. Studio Technologies
offers headset connector assemblies that
allow fast and painless installation into
a spare connector location in the Model
230’s back panel. Details about these
optional assemblies are available on the
Studio Technologies website.
Options
The Model 230’s standard resources are
more than sufficient to directly support a
large number of applications. But in the “real
world” of audio and intercommunications
special needs always seem to arise. To that
end, Studio Technologies offers a number of
option cards. In addition to passive or active
components, each card contains an integral
connector, allowing simple installation into
a spare connector location on the Model
230’s back panel. For interest, the resources
provided by some of these option cards are
worth describing.
• The direct microphone output card pro-
vides access to the dynamic or condenser
microphone that is connected to the
Model 230’s mic input. Passive compo-
nents, along with the auxiliary relay con-
tact, create a “click-free” microphone-level
audio signal.
• The line output card allows the Model 230
to provide a second line-level talkback
output.
• The remote switch input card uses a 4-pin
XLR connector to provide access to the
Model 230’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.
