Studio Technologies Upgrades
Audio Interfaces

S

tudio Technologies has begun
shipping its Model 46A and 47A
audio interfaces.
Building on the strengths of the
units' predecessors, the new versions
offer improved circuitry and software
in a more compact and lightweight
package.
"From the start, the overriding
design goal for both products was
to create a 'new breed of cat' that
fundamentally changed how broadcast
two to four-wire interface equipment
performed in actual applications,"
says Gordon Kapes, President of
Studio Technologies. We can describe
these products in conventional terms,

Model
46A and
47A audio
interfaces

but their real strength rests in their
excellent
real-world
integration
and performance with two-wire
party-line (PL) intercom circuits. Our
conversations with industry experts
alerted us to the significant effort
necessary to install and configure
existing two to four-wire interface
units, as well as their wide range of
results. Our original Model 46 and 47
designs addressed the requirements
in a more effective way, and the latest
enhancements continue to improve the
units' performance."
The Model 46A is designed for
sports and special-event broadcasting;
theme park and theatre installations;

and corporate event environments.
The unit provides two two-channel
partly-line interfaces that allow direct
connection of user belt packs and
related devices.
The Model 46A's four-wire inputs
and outputs are directly compatible
with the matrix intercom systems that
are standard in live-event broadcast
and production facilities.
The Model 47A also provides dual
two to four-wire analogue audio
interfaces, but with the addition of
power and audio on both channels of
both party-line interfaces - a total of
four powered PL channels. This makes
the unit suitable for mobile and fixed
television facilities that utilise a Source
Assignment Panel (SAP) for PL channel
routing and configuration.

In addition, both the Model 46A and
47A now offer improved PL output
currents for an additional "margin" for
connected devices. Also, the internal
power supplies on both units have
been revised for increased efficiency.
A new generation of microcontrollerintegrated
circuitry
allows
for
faster and more accurate software
performance. Both products support
other specialised audio systeminterfacing applications, and provide
two independent, full-featured twochannel interfaces.
Each interface contains two hybrid
circuits that include automatic-nulling
capability.
The analogue circuitry of the
products, under software control,
provides excellent audio quality and
high return-loss.
The interfaces are compatible with
powered and unpowered two-wire PL
circuits and are capable of supplying
DC power, allowing direct
operation of devices such
as user beltpacks and user
stations.
