RDL ST-VP2 Automatic Ducking Module

Because clear and consistent audio management is crucial for professional broadcasting and public address systems, the ST-VP2 Automatic Ducking Module emerges as an indispensable tool for audio technicians and broadcasters. This high-quality, durable module integrates seamlessly into any line-level input of a paging amplifier, offering a user-friendly solution for maintaining balanced audio levels during live announcements or broadcasts.

The ST-VP2 is designed to accommodate a variety of line-level music sources, such as those from receivers, satellite decoders, tape decks, or CD players. Additionally, it can accept voice signals from a telephone paging system or a preamplified microphone, ensuring versatile compatibility with different audio setups (compatible with RDL STM-1, STM-2, STM-2X, STM-3, STM-LDA3 Microphone Preamplifiers).

Innovative in its operation, the ST-VP2 module automatically detects the presence of an audio signal at its input when a page is initiated. It then adeptly lowers the music to a pre-set level, allowing the voice announcement to take precedence without any manual intervention. Once the announcement is complete, the module gracefully fades the music back to its original level, ensuring a smooth transition between voice and music.

The voice input remains inactive until the module receives the next paging signal, thereby preventing any unwanted noise from entering the system. This reliable module is engineered to simplify setup and monitoring with two front-facing LED indicators that display the correct operating levels for both the voice and music inputs.

Moreover, the music input is equipped with an AGC (Automatic Gain Control)/Compressor feature. This innovative addition works transparently to normalize varying music source levels and safeguards against excessive music volumes that could interfere with voice announcements.

The ST-VP2 Automatic Ducking Module is the perfect choice for users seeking a seamless, hands-free solution to manage audio ducking with precision and reliability. Its push-to-talk controller feature further enhances user control, making it a superior choice for professional audio applications where clear and uninterrupted communication is paramount.
