Genelec 9301B Multichannel AES/EBU Interface

Multichannel Digital Interface for Genelec Immersive Audio Systems
The Genelec 9301B Multichannel AES/EBU Interface is purpose-built for integrating Genelec 7300 Series Smart Active Subwoofers into immersive audio environments. Acting as a high-performance digital I/O expander, the 9301B provides the necessary connectivity for routing multichannel AES/EBU signals directly to your subwoofer and SAM monitoring system. It’s a compact yet vital component when building immersive setups like 7.1.4, 9.1.6, or larger formats—enabling precision bass management and full system calibration using Genelec’s Loudspeaker Manager (GLM) software.

Provides 16 Channels of AES/EBU Digital Audio
Designed to simplify complex audio routing, the 9301B offers 16 input and output channels over AES/EBU via DB25 connectors, following the TASCAM AES59-2012 standard. These channels are seamlessly merged into a single AES/EBU stream that connects directly to the 7300-series subwoofer's digital input. This direct link not only ensures clean signal integrity but also integrates smoothly with the subwoofer's internal crossover, allowing for centralized system calibration and control through GLM.

Supports Immersive Formats up to 9.1.6 and Beyond
Whether you're working in Dolby Atmos, DTS:X, or other multichannel formats, the 9301B offers the capacity and expandability required for immersive workflows. A single unit supports up to 16 discrete audio channels, and if your configuration exceeds that—say a 22.2 layout—you can add a second 9301B and a second 7300 Series subwoofer. This flexible scalability makes the 9301B suitable for post-production studios, high-end music mixing rooms, and broadcast environments handling multichannel content.

Ensures Full-Bandwidth Audio at Professional Sample Rates
The 9301B supports a wide range of professional audio formats with sample rates from 32 kHz to 192 kHz and word lengths from 16-bit to 24-bit. This broad compatibility means your system stays future-proofed, ready to handle high-resolution audio sessions in any modern DAW or digital mixing environment. For those who need reliability and transparency in their digital signal path, the 9301B ensures your audio arrives at the subwoofer exactly as intended.

Streamlines Signal Chain Integration with Simple I/O
The unit features two DB25 inputs and one DB25 output for AES/EBU multichannel audio, plus a dedicated XLR output for connection to a Genelec subwoofer. This streamlined connectivity eliminates the need for complicated patching or additional converters. Just insert the 9301B between your digital source and subwoofer, and the system is ready for GLM alignment and automated room calibration. Its rack-friendly form factor and reliable performance make it an easy addition to any studio configuration.

Pairs Seamlessly with GLM Software for Full System Calibration
Once connected, the 9301B enables precise system alignment using Genelec's GLM software. This includes subwoofer phase and level optimization, group delay correction, and bass management settings tailored to your specific room acoustics. With this integration, you get consistent monitoring across all channels of your immersive system—including the LFE—ensuring that your mixes translate across playback systems.

Expand Monitoring Capabilities with Dual 9301B Units
For larger systems, two 9301B units can be used in tandem with two Genelec 7300 Series subwoofers to double the channel count to 32. This setup supports large-scale configurations and provides more flexibility in routing and system layout, making it ideal for theaters, large-scale post suites, and advanced music mixing studios aiming for highly detailed spatial audio playback.
