technology that provides mediocre perfor-
mance. That’s why Studio Technologies
developed high-performance IFB interface
units. These products do an excellent job
of providing power and audio to connected
devices such as the Model 230. However,
unlike other products, the power supplied
by the IFB circuits created by these units
maintains their output voltage all the way
to their full rated current. The result is
being able to power more devices over
longer cable runs. In addition, the audio
quality of these units is superior. For further
information please refer to the Studio Tech-
nologies website.
LED Colors
As previously described, two LED indica-
tors are associated with the main output
and are located directly above the main
output pushbutton switch. The red LED,
located on the left, is lit whenever the main
output is muted. The green LED, located
on the right, is lit whenever the main output
is active. The thought process behind the
color choices was that red would relate
to the main output being muted (“stop”)
while green would relate to the main output
being active (“go”). It’s possible that these
color choices may not meet the needs of
all users and applications. For example, it’s
reported that one European broadcaster
typically uses these two colors in the oppo-
site fashion. Their choice is to have the red
LED lit whenever the main output is active,
warning the talent that they are “on-air.”
The green LED is lit whenever the main
output is muted, indicating to the talent that
it’s “safe” to say whatever they wish, about
whomever they wish to say it about!
For consistency, the LEDs associated with
the talkback buttons were selected to be
green. They light whenever their associated
talkback functions are active. It’s possible
that some applications may benefit from
revising these LED colors too. While red is
certainly one possible choice, other colors
are also a possibility, including amber, or-
ange, blue, or white—these days there are
lots of choices available.
A qualified technician can easily revise
the LED colors to meet an application’s
exact needs. The process would begin
by disassembling the Model 230’s enclo-
sure and detaching the pushbutton/LED
printed circuit board assembly. The LEDs
would then be unsoldered, removed, and
reinstalled (or replaced) in the desired loca-
tions. To control the LED current and set
the brightness, a 825 ohm 1206-size sur-
face-mount resistor is electrically in series
with each LED.
For additional information about changing
the LED colors, please contact Studio
Technologies’ technical support.
Travel Case
For portable applications it may be desir-
able to store and transport each Model 230
in a protective case. After much travel with
prototype announcer console units, Studio
Technologies personnel learned to appre-
ciate the Pelican Model 1450 case. Pur-
chased with the foam interior option, it does
an excellent job of holding one Model 230,
its associated 24 volt DC power supply, and
documentation. Some applications may
benefit from selecting a larger case that
would also hold a related headset, cables,
etc. A larger case could also be selected
that would hold multiple Model 230 units.
Pelican sells their products through a deal-
er network, many of which can be located
via a web search.
