BDI DAB-300-1 Dual Path IBOC Switcher

Professional Dual Path Audio Switching Solution

The BDI DAB-300-1 Dual Path IBOC Switcher is engineered to meet the demands of modern broadcast operations by allowing two audio paths—analog and digital—to be switched simultaneously. This capability ensures precise time alignment between both transmission formats, which is essential for maintaining proper performance in in-band on-channel (IBOC) broadcasting. Whether in daily operation or during a failure in one audio path, the DAB-300 provides smooth, uninterrupted transitions for consistent on-air quality.

Reliable Performance with Automatic Silence Detection

Equipped with BDI’s advanced silence detection system, the DAB-300 switches audio paths automatically when an interruption is detected, eliminating the need for constant operator monitoring. Configurable thresholds, delay times, and revert settings ensure the switcher responds exactly as your application requires. The programmable priority sequence allows you to define which channel takes precedence, giving you complete control over failover behavior.

Versatile Control Options for Any Workflow

The DAB-300 can be operated directly from the front panel, through GPIO connections, via Ethernet using SNMPv2, or with the BDI Stack Graphical User Interface for Windows and Android. The GUI provides a user-friendly way to label inputs and outputs, simplifying operation in busy broadcast environments. With SNMP support, the DAB-300 integrates seamlessly into remote control systems, requiring nothing more than a simple CAT5 connection for setup.

Flexible Input and Output Configurations

Designed for versatility, the DAB-300 supports up to eight input and output channels in analog, AES3 digital, or a combination of both. Composite FM stereo I/O modules are available, offering four composite outputs and composite-to-AES3 conversion. Each AES3 input features built-in sample rate conversion, ensuring compatibility across various audio sources. The synchronous AES3 switching design guarantees silent, glitch-free transitions between sources.

High-Quality Digital Signal Processing

With 24-bit resolution throughout the signal path, the DAB-300 maintains exceptional audio quality in all configurations. Its DSP-based architecture provides reliable, precise operation while fitting into a compact single rack unit chassis. This makes it a cost-effective solution for broadcasters seeking high performance without sacrificing space or flexibility in their equipment racks.

Durable Build for Continuous Operation

The DAB-300 is built for the rigorous demands of continuous broadcast operation. Its robust construction and advanced electronics ensure consistent performance even under demanding conditions. Combined with its flexible control and input options, the DAB-300 is a dependable choice for stations that need a compact, all-in-one dual path switching solution.
