Skokie, IL (December 14, 2015)—Studio Technologies has begun shipping new versions of its Model 46A and 47A partly-line interfaces that reportedly offer improved circuitry and software in a more compact package.
“From the start, the overriding design goal for both products was to create a ‘new breed of cat’ that fundamentally changed how broadcast 2- to 4-wire interface equipment performed in actual applications,” says Gordon Kapes, president of Studio Technologies. “We can describe these products in conventional terms, but their real strength rests in their excellent real-world integration and performance with 2-wire party-line (PL) intercom circuits.
“Our conversations with industry experts alerted us to the significant effort necessary to install and configure existing 2- to 4-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 theater installations; and corporate event environments. The unit provides two 2-channel partly-line interfaces that allow direct connection of user belt packs and related devices. New changes include a 2.5-pound weight reduction, a lower audio noise floor and improved noise immunity.
The Model 47A also provides dual 2- to 4-wire analog 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 intended for mobile and fixed television facilities that utilize a Source Assignment Panel (SAP) for PL channel routing and configuration. The new Model 47A has a weight reduction of four pounds and a depth reduction of almost two inches. The audio noise floor has also been improved as well as enhanced immunity from ESD (“static” discharge).
