BDI ATB-300-2 Audio Tool Box 4 AES I/O, 4 Analog L/R Balanced Input

Rack-Mounted Audio Switching and Routing Solution
The Broadcast Devices ATB-300-2 Audio Tool Box is a professional rack-mounted system designed for seamless digital and analog audio switching. This configuration features four analog balanced stereo inputs alongside four AES3 digital inputs and outputs, making it an essential component for broadcast studios, production environments, and live audio setups. With advanced routing capabilities, programmable failover protection, and remote control functionality, the ATB-300-2 ensures high-quality audio signal management for demanding applications.

Seamless Integration of Analog and Digital Audio
The ATB-300-2 is built for facilities that require a hybrid of analog and digital audio processing. With four AES3 digital I/O and four balanced analog stereo inputs, this unit allows smooth transitions between legacy and modern audio infrastructures. Whether working in a fully digital system or integrating analog sources into an AES3-based workflow, the ATB-300-2 delivers clean, reliable signal transmission without degradation.

Automatic Silence Detection and Failover Protection
Uninterrupted audio performance is crucial in live broadcasting and production settings. The ATB-300-2 includes a programmable silence detection system that monitors audio signals in real time. Users can configure silence thresholds, time delays, and automatic revert settings to ensure that the unit instantly switches to a backup source when a signal drop is detected. Once the primary signal is restored, the system seamlessly reverts to the original source without interruptions.

Smooth and Artifact-Free Audio Switching
Broadcast Devices’ proprietary Silent Switch technology ensures that source transitions occur without audible artifacts or signal disruptions. This is particularly beneficial for digital workflows that require synchronous AES3 switching, allowing smooth transitions between sources with no glitches or noise. Frame rate conversion on all digital inputs further enhances compatibility with multiple sample rates, eliminating potential syncing issues.

User-Friendly Configuration and Advanced Routing Control
The front-panel menu provides an intuitive interface for configuring input mode selection, gain adjustments, and input phase inversion. Users can program up to eight channels for automatic failover, making the ATB-300-2 a highly customizable solution for complex audio routing needs. The ability to prioritize channels and adjust signal flow ensures that professional audio environments maintain maximum reliability.

Remote Control Compatibility and Power Fail Recovery
The ATB-300-2 is fully remote-control ready, featuring a standard parallel control interface with an optional serial control module for integration into automation systems. Programmable alarm contacts provide real-time monitoring and allow for remote activation of backup sources. In the event of a power failure, the power fail memory function restores the last channel selection upon reboot, ensuring continued operation without requiring manual reconfiguration.
