About the Evertz 7700ADA-AUD Balanced Analog Audio Distribution Amplifier
The Evertz 7700ADA-AUD is a high-quality balanced analog audio distribution amplifier module designed for integration within the Evertz 7700 series modular frame system. Its primary function is to accept a single professional-grade balanced analog audio input, typically at line level, and amplify and distribute it to multiple isolated outputs with exceptional signal integrity. This device is essential in broadcast facilities, post-production studios, and live sound environments where a clean audio source—such as from a console master output, playback device, or master clock tone—needs to be sent simultaneously to numerous destinations like recording decks, monitor systems, routers, or transmission encoders without signal degradation.
Engineered for transparent performance, the module utilizes premium components and circuitry to maintain the original audio signal's frequency response, dynamic range, and phase coherence while providing substantial drive capability for long cable runs. It features fully balanced inputs and outputs using XLR or terminal block connectors, offering superior common-mode noise rejection to eliminate hum and interference often encountered in complex installations. Each output is individually buffered and isolated, preventing load impedance variations on one output from affecting the signal quality on any other, ensuring consistent level and stability across all connected devices.
As a slide-in card for the centralized 7700 frame, the 7700ADA-AUD benefits from the frame's redundant power supplies and unified control/monitoring via software. This design provides a reliable, scalable, and neatly organized solution for critical audio infrastructure, consolidating multiple distribution points into a single managed platform. Its robust build and precision engineering make it a trusted component for distributing critical audio reference signals, program audio, or intercom feeds where absolute reliability and sonic fidelity are non-negotiable.
