BDI ATB-300-4 Audio Tool Box

Professional Rack-Mounted Analog Audio Switching System
The Broadcast Devices ATB-300-4 Audio Tool Box is a high-performance rack-mounted switching and routing system designed for professional analog audio applications. This configuration includes four analog L/R balanced inputs and outputs, making it an ideal choice for studios, broadcast facilities, and live sound setups that require precise and reliable signal management. With user-friendly programming options, automatic failover protection, and remote control capabilities, the ATB-300-4 ensures seamless operation in demanding audio environments.

Fully Analog Balanced Audio for Superior Signal Integrity
Built for systems that rely exclusively on analog signal processing, the ATB-300-4 provides four analog L/R balanced inputs and outputs, ensuring clear and interference-free audio transmission. Its balanced architecture minimizes noise and distortion, making it well-suited for professional applications where high-fidelity audio is critical. This all-analog configuration is perfect for facilities that prioritize robust and reliable analog audio routing.

Automatic Signal Reversion and Silence Detection
To prevent audio disruptions, the ATB-300-4 is equipped with programmable silence detection that continuously monitors the input signal. If a signal drop occurs, the system can automatically switch to a pre-configured backup source, ensuring uninterrupted audio playback. Once the primary signal is restored, the revert function seamlessly transitions the system back to its original channel without manual intervention.

User-Friendly Programming for Flexible Routing Control
The front-panel menu system provides intuitive access to essential programming features, allowing users to adjust input/output gain, input phase inversion, and input mode selection. With the ability to assign priority channels and configure up to eight failover sources, the ATB-300-4 offers a flexible and customizable routing solution for professional audio environments.

Seamless Switching with No Artifacts or Dropouts
Broadcast Devices’ proprietary Silent Switch technology ensures that transitions between sources remain seamless and free of unwanted noise. This advanced feature eliminates switching artifacts, providing smooth audio routing without interruptions. While digital models offer frame rate conversion, this analog-only version focuses on delivering pristine analog audio output with no digital interference.

Remote Control Compatibility and Power Fail Recovery
Designed for integration into modern professional systems, the ATB-300-4 supports both parallel standard and optional serial interface control, allowing for remote management and automation. Programmable alarm contacts provide real-time status monitoring and allow for remote activation of backup sources. In the event of a power failure, the unit’s memory retains the last channel selection, ensuring continuity when power is restored.
