Studio Technologies Model 47A Dual 2-Wire Analog Audio to 4-Wire Analog Audio Interface Interface

Studio Technologies Model 47A: Bridging Party-Line and Matrix Systems
The Studio Technologies Model 47A Interface expertly melds 2-wire full-duplex party-line (PL) intercom circuits with 4-wire audio circuits, a staple in matrix intercom systems. This dual 2-wire to 4-wire audio interface caters to a variety of specialized audio interfacing needs beyond its primary function, making it an indispensable tool in professional broadcast and production environments. Whether for mobile TV units, fixed installations in theaters, or complex industrial setups, the Model 47A provides reliable, high-quality audio interfacing.

Dual Independent Interfaces for Versatile Audio Management
Each of the Model 47A’s two independent interfaces is equipped with two hybrid circuits featuring automatic nulling capabilities to minimize echo and feedback, ensuring clear communication. This sophisticated analog circuitry, managed by precise software control, delivers exceptional audio quality and high return loss, crucial for maintaining sound integrity in professional settings.

Advanced Power and Connectivity Features
The Model 47A stands out with its ability to supply DC power directly to devices like user beltpacks and stations, enhancing its utility in dynamic production environments. Each interface’s power sources are independently managed, supporting both powered and unpowered 2-wire party-line circuits. This flexibility is essential for accommodating various types of audio equipment and user needs in diverse operational contexts.

Configurable and User-Friendly Design
Ease of configuration and user interaction are at the forefront of the Model 47A’s design. Audio level meters allow operators to monitor and confirm system performance effectively, ensuring optimal operation during setup and live broadcasts. Configuration settings are adjustable to be compatible with a wide range of nominal signal levels, providing further adaptability to meet specific user requirements.

Robust Construction and Seamless Integration
Designed to occupy a single rack unit (1U) in a standard 19-inch rack enclosure, the Model 47A maximizes space efficiency without compromising functionality. Its universal mains input (100-240 V, 50/60 Hz) ensures that it can operate worldwide, complemented by standard audio connectors for all input and output signals, simplifying installation and integration into existing setups.
