Description
Overview
The Hosa ODL-312 Digital Audio Interface is a professional hardware converter designed to bridge the gap between two common but incompatible digital audio standards: S/PDIF Optical (Toslink) and AES/EBU (XLR). This interface ensures that your digital signal chain remains intact, allowing you to interconnect digital audio workstations (DAWs), professional recorders, and high-end outboard gear regardless of their native I/O formats.
Key Details
- Bidirectional Conversion: Supports two-channel S/PDIF optical to AES/EBU and vice versa, allowing for flexible signal routing.
- Simultaneous Transfer: Capable of performing conversion in both directions at the same time if your workflow requires it.
- High-Resolution Audio: Full support for 24-bit/96 kHz S/PDIF audio, ensuring professional-grade fidelity and transparency.
- Complete Power Solution: Includes the necessary AC adapter for immediate deployment in your studio.
Use Cases
- Hybrid Studio Integration: Connecting a modern audio interface with an optical output to a legacy professional processor or converter that only accepts AES/EBU XLR inputs.
- Digital Clocking & Routing: Syncing digital gear across a studio where different manufacturers have utilized different digital standards.
- Professional Recording: Routing high-resolution digital audio from a digital mixer (S/PDIF) into a professional digital recording machine (AES/EBU).
Installation
Installation is straightforward and requires no software configuration. Connect your S/PDIF optical cable to the Toslink port and your AES/EBU cable to the XLR port. Plug in the included AC adapter to power the unit. Ensure that both the sending and receiving devices are set to the same sample rate (up to 96 kHz) to avoid clocking errors or digital jitter.
Compatibility
Detailed compatibility information is not available from current supplier or official product data, however, the unit is designed for any hardware utilizing standard S/PDIF Optical (Toslink) and AES/EBU (XLR) digital audio protocols.
