Studio Technologies Model 46A Dual 2-Wire Analog Audio to 4-Wire Analog Audio Interface

Enhance Audio Integration with Studio Technologies Model 46A
The Studio Technologies Model 46A serves as a sophisticated interface designed to seamlessly integrate 2-wire full-duplex party-line (PL) intercom circuits with 4-wire audio circuits commonly found in matrix intercom systems. This dual-functionality makes the Model 46A an invaluable asset for broadcasting and live event productions, where clear and reliable communication is essential. Its capability to support other specialized audio system interfacing applications further extends its utility across various audio engineering fields.

Dual Independent Interface Capability
Each of the two independent interfaces within the Model 46A boasts a pair of hybrid circuits with automatic nulling capabilities, which are crucial for minimizing echo and feedback in audio paths. This feature ensures that the audio quality remains pristine and communication clear, regardless of the operational environment. These interfaces are adept at handling both powered and unpowered 2-wire party-line circuits, enhancing their versatility and applicability in a multitude of settings.

Power and Performance in One Device
The Model 46A is not just about interfacing; it also supplies DC power, making it possible to directly operate devices such as user beltpacks without the need for additional power sources. This integrated power capability, coupled with configurable settings for matching different nominal signal levels, makes the Model 46A a powerful tool for simplifying audio setups and reducing equipment clutter.

Comprehensive Monitoring and High-Quality Audio
With input and output level metering, users of the Model 46A can easily monitor and confirm system performance, ensuring optimal settings during both setup and live operation. The exceptional audio quality produced by the Model 46A's analog circuitry, which is under precise software control, guarantees that audio signals are transmitted with high fidelity and significant return loss, thus maintaining the integrity of the sound throughout the system.

Versatile and User-Friendly Design
The Model 46A is designed to fit seamlessly into a standard 19-inch rack enclosure, occupying only one rack space for efficient space management. It is equipped with standard audio connectors for all input and output signals, simplifying the integration process with existing audio equipment. Powered by universal input mains (100-240 V, 50/60 Hz), the Model 46A is ready for global use in a variety of professional settings, from television sports broadcasts to corporate events and theater installations.
