DENVER, CO — As the landscape of home audio continues to evolve toward complex, multi-room, and distributed systems, the challenge of maintaining pristine sonic fidelity across varied acoustic environments has become the primary hurdle for professional integrators. At the 2026 CEDIA Expo, a significant milestone in this pursuit was reached: Swedish digital audio pioneer Dirac and legendary manufacturer NAD Electronics announced that the NAD CI SA2-120 BluOS Streaming Amplifier Module and the CI S2 BluOS Streaming Module are now officially certified for Dirac Live Room Correction.
This integration represents more than a simple firmware update; it is a strategic alignment of NAD’s robust, modular hardware architecture with Dirac’s industry-leading digital signal processing (DSP). For the professional integrator, this partnership promises to turn unpredictable residential acoustics into controlled, high-fidelity soundscapes.
The Core Advancement: Why Dirac Live Matters
In any professional installation, the room itself is the most significant "component" in the audio chain. Even the most expensive speakers and amplifiers cannot overcome the physical realities of standing waves, bass nulls, and early reflections caused by walls, furniture, and room geometry.
Dirac Live Room Correction operates by analyzing the specific interaction between the audio system and the listening space. Unlike traditional equalization, which often focuses solely on frequency response, Dirac Live addresses the temporal domain. By correcting both the magnitude and the phase response of the audio signal, the technology ensures that sound arrives at the listener’s ears in perfect alignment.
For the end user, this manifests as a dramatic increase in clarity, a tighter and more authoritative bass response, and a stable, holographic soundstage that remains cohesive regardless of the room’s shape. By bringing this level of sophistication to the NAD CI Modular Series, the two companies are effectively democratizing high-end acoustic calibration for custom residential projects.
A Chronology of Collaboration
The journey toward this announcement began with the broader evolution of the NAD CI Modular Series. Recognizing that modern homes require flexible, scalable, and rack-mountable audio solutions, NAD developed the CI Modular platform to provide integrators with a "Lego-like" approach to distributed audio.
- Initial Development: NAD launched the CI Modular Series to offer a high-performance alternative to traditional, bulky distribution amplifiers. The series prioritized compact form factors without sacrificing the audiophile-grade DNA NAD has been known for since 1972.
- The Rise of BluOS: The integration of the BluOS high-resolution streaming platform turned these amplifiers into intelligent, networked devices. This digital backbone provided the necessary interface for future-proofing, allowing for over-the-air updates.
- The Dirac Partnership: Recognizing that hardware performance is only half the battle, NAD and Dirac entered a multi-year development cycle aimed at porting the sophisticated algorithms of Dirac Live into the CI ecosystem.
- CEDIA Expo 2026: The official certification was unveiled, marking the culmination of months of beta testing and optimization to ensure that the Dirac processing would not impose latency or instability on the BluOS streaming environment.
Supporting Data: The NAD CI Modular Series Portfolio
The NAD CI Modular Series is designed to address the specific needs of modern AV integrators. The inclusion of Dirac Live now spans across key units that serve as the backbone of high-end home installations.
The CI SA2-120 BluOS Streaming Amplifier
This unit serves as the "workhorse" of the series. Designed for single or dual-zone applications, the SA2-120 combines high-efficiency amplification with full-featured BluOS streaming. Its compact, rack-friendly design allows integrators to save precious space in equipment closets while providing 120 watts per channel—enough to drive high-performance architectural speakers with authority.
The CI S2 BluOS Streaming Module
For systems where amplification is already provided or where the integrator prefers separate components, the CI S2 acts as the digital heart of the system. It offers two independent zones of high-resolution streaming, allowing for distinct content delivery across different areas of the home.
The CI PA4-60 Power Amplifier
While not a streaming module, this four-channel power amplifier rounds out the ecosystem. It provides the necessary power headroom for larger distributed systems, ensuring that even in expansive home audio setups, the signal remains clean and dynamic.
Official Perspectives: The Vision Behind the Integration
The partnership is driven by a shared philosophy: that the quality of a system is defined by its ability to perform in the real world, not just in a lab.
Rikard Hellerfelt, VP and Head of Consumer Electronics at Dirac, emphasized the limitations of hardware in isolation. "Every room shapes sound in ways that even premium audio hardware cannot address on its own," Hellerfelt noted. "By expanding Dirac Live Room Correction to NAD’s CI SA2-120 and CI S2, we’re giving professional integrators a powerful tool to unlock the full performance of distributed audio systems while creating consistently exceptional listening experiences across the home."
Peter Gibb, Custom Install Product Manager at NAD Electronics, highlighted the integrator’s perspective: "For custom integrators, every project presents a unique acoustic environment. Bringing Dirac Live Room Correction to the CI SA2-120 and CI S2 pairs the flexibility of our modular CI platform with powerful room optimization, helping integrators achieve exceptional, consistent sound across a wide range of spaces and system configurations."
Implications for the Custom Installation Market
The certification of these NAD components carries significant implications for the future of the CI industry.
1. Reducing Calibration Time
Traditionally, room correction was reserved for high-end dedicated home theaters. By integrating it into distributed audio modules, Dirac and NAD are encouraging a "pro-audio" approach to living rooms, kitchens, and patios. Integrators can now use the NAD Dirac Room Calibration Kit to perform precise measurements, significantly reducing the "trial and error" time usually spent adjusting EQ settings in a complex multi-room setup.
2. Bridging the Gap Between "Hi-Fi" and "Whole-Home"
Historically, there has been a divide between audiophile-grade stereo systems and convenient, whole-home audio. The CI SA2-120, now with Dirac Live, erases this line. It allows users to enjoy the convenience of streaming services like Tidal, Qobuz, or local NAS libraries, while benefiting from the same acoustic correction technologies used by top-tier recording studios.
3. Scalability and Longevity
Because the Dirac Live capability is software-driven and resides within the BluOS architecture, it adds long-term value to the installation. As Dirac continues to refine its algorithms, users can expect the performance of their installed hardware to improve through software updates. This longevity is critical for integrators, who need to provide clients with solutions that won’t become obsolete within a few years.
How to Implement Dirac Live in NAD Systems
For integrators and users looking to implement this technology, the process is straightforward but requires precision:
- Hardware Requirements: Ensure the CI SA2-120 or CI S2 is installed and connected to the network.
- Calibration Kit: Acquire the official NAD Dirac Room Calibration Kit. This kit includes the calibrated measurement microphone and necessary adapters required to capture accurate room data.
- Licensing: Users can purchase the Dirac Live Full Bandwidth license directly through the Dirac website. The license is tied to the specific unit, ensuring that the DSP resources are dedicated to that zone.
- Measurement: Using the Dirac Live software interface, the user performs a series of sweeps in the room. The software analyzes the data and generates a target curve.
- Application: The resulting filter is uploaded to the NAD device, where it runs locally on the unit’s processor, ensuring no impact on streaming performance or audio latency.
Conclusion: A New Standard for Excellence
The collaboration between NAD Electronics and Dirac represents a maturation of the custom installation market. As smart homes become more sophisticated, the expectations of homeowners have shifted; they no longer accept "background music" quality in their primary living spaces. They demand the same clarity and impact in the kitchen or the bedroom that they enjoy in their dedicated media rooms.
By equipping the NAD CI Modular Series with the world’s most respected room correction technology, NAD and Dirac have set a new benchmark. For the integrator, it is a powerful differentiator that ensures their projects stand out for their sonic excellence. For the listener, it is the realization of a promise: that no matter how difficult the room, the music will sound exactly as the artist intended.
For those attending the CEDIA Expo 2026 in Denver, the Lenbrook Booth (3319) serves as the epicenter for these demonstrations. Seeing—and hearing—the difference that Dirac Live makes on the NAD CI platform is the final argument for why this integration is the most significant development in custom audio this year.
