The Model 233’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 
passive or active components, each card 
contains an integral connector, allowing 
simple installation into a spare connector 
location on the Model 233’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 233’s mic input. Passive 
components, 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 233’s remote switch inputs.

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 imag-
ine 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.

In this section interconnections will be 
made using the input and output connec-
tors located on the Model 233’s back pan-
el. Microphone, line-level audio sources, 
intercom, main output, and line-level talk-
back output signals are interfaced by way 
of 3-pin XLR-type connectors. 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.

The following is included in the shipping 
carton: Model 233 Announcer’s Console, 
user guide, button label sheet, and 24 volt 
DC power supply. For units shipped to des-
tinations in Japan and North America the 
power supply will have a nominal AC mains 
input of 120 volts. For all other destinations 
a power supply compatible with 220/240 
volt AC mains will be included.

The Model 233 is compatible with balanced 
dynamic and condenser microphones. 
Depending on the application, the micro-
phone may be part of a headset, or be an 
independent handheld or stand-mounted 
model. The Model 233’s nominal 48 volt 
power source will support essentially all 
phantom-powered microphones. The qual-
ity of the Model 233’s microphone pream-
plifier and associated circuitry is such that 
special applications may benefit from using 
“high-end” microphones. If selected appro-
priately, models from manufacturers such 
as AKG, Beyerdynamic, Crown, Neumann, 
Sennheiser, and Shure will perform very 
well in Model 233 applications.
