Professional Dual-Format Conversion

The RB-ADDA is a powerful 1U rack-mount solution designed for studios that need to bridge the gap between analog and digital domains. It provides high-quality A/D conversion from 2 analog inputs (XLR or RCA) to 1 digital AES/EBU or S/PDIF stream, while simultaneously performing D/A conversion from 1 digital input to 2 analog outputs (XLR or RCA). This dual-path architecture makes it an essential tool for integrating legacy gear, such as cassette decks or portable players, into modern digital workflows.

Intelligent Synchronization

Engineered for reliability, the RB-ADDA operates in four specialized sync modes, ensuring your audio remains perfectly timed across complex systems. Whether it is running off its high-precision internal master clock at up to 96kHz or locking to an incoming digital signal in Slave or Auto modes, you are guaranteed jitter-free performance. A clear front-panel LED indicator provides instant visual confirmation of sync status, so you always know your digital clocking is locked.

Precision Control and Calibration

Tailored for the professional engineer, the unit features comprehensive level adjustments for both input and output stages. Users can easily calibrate levels to accommodate a wide range of signal strengths, from standard consumer devices to high-headroom professional gear. With advanced features like 50/15µs emphasis decoding and selectable bit-depth dithering, the RB-ADDA ensures that your audio remains transparent, accurate, and perfectly matched to your destination system.
