DENVER, CO — At the 2026 CEDIA Expo, the professional audio industry witnessed a significant convergence of high-fidelity performance and custom installation flexibility. Swedish digital audio pioneer Dirac and renowned electronics manufacturer NAD Electronics have officially announced that the NAD CI SA2-120 BluOS Streaming Amplifier Module and the CI S2 BluOS Streaming Module are now certified for Dirac Live Room Correction. This strategic integration marks a pivotal expansion of Dirac’s advanced acoustic optimization technology within NAD’s specialized CI (Custom Install) portfolio, promising to redefine the standard for sound in distributed residential audio systems.
The Convergence of Power and Precision: Main Facts
For professional integrators, the challenge has long been balancing the constraints of room architecture with the desire for audiophile-grade sound. The announcement at the Colorado Convention Center underscores a shift toward "smart" hardware that adapts to the environment rather than fighting it.
The NAD CI Modular Series, known for its space-efficient, high-performance design, is now bolstered by the industry’s most sophisticated room correction software. By integrating Dirac Live, the CI SA2-120 and CI S2 units gain the ability to analyze a room’s specific acoustic footprint—accounting for reflections, standing waves, and uneven frequency responses—and calibrate the output to compensate for these deficiencies.
Key highlights of the integration include:
- Full-Bandwidth Optimization: The Dirac Live certification allows for correction across the entire audible frequency range, ensuring consistent, high-fidelity sound.
- Modular Synergy: The CI SA2-120, which combines amplification and BluOS streaming, and the CI S2, a dedicated dual-zone streaming module, are now capable of being tuned to the unique acoustic properties of any room they serve.
- Professional Calibration: Utilizing the NAD Dirac Room Calibration Kit, installers can perform precise measurements, effectively turning unpredictable living spaces into controlled acoustic environments.
A Legacy of Innovation: Chronology of the Partnership
The relationship between NAD Electronics and Dirac has been one of the most fruitful collaborations in modern audio engineering. To understand the significance of this 2026 expansion, one must look at the evolution of their partnership:
- The Early Years: NAD Electronics, founded in 1972, built its reputation on the "Music First" philosophy, prioritizing sonic purity over flashy features.
- The Digital Shift: As the industry moved toward digital signal processing (DSP), NAD began incorporating more advanced room management tools.
- Dirac Integration: Dirac, based in Uppsala, Sweden, gained international acclaim for its patented algorithms that correct both magnitude and phase. The initial integration of Dirac Live into NAD’s flagship receivers set a new benchmark for high-end home theater.
- The CI Expansion (2024–2025): Recognizing that custom integrators were facing increasing demands for high-fidelity audio in non-traditional rooms (such as open-plan kitchens, bedrooms, and patio areas), NAD developed the CI Modular Series.
- The 2026 Milestone: With the official certification announced at CEDIA 2026, the two companies have successfully brought "reference-grade" audio technology into the realm of the professional installer, closing the gap between high-end hi-fi and whole-home distribution.
The Science of Sound: Supporting Data and Technology
To appreciate the impact of Dirac Live, one must understand the physics of the listening environment. When sound is played in a room, it does not travel in a straight line from the speaker to the listener; it interacts with walls, floors, ceilings, and furniture. These interactions cause frequency peaks and dips, as well as timing errors known as phase distortion.
How Dirac Live Changes the Equation
Dirac Live operates on a complex mathematical model that corrects two distinct categories of acoustic issues:
- Frequency Response: By measuring the sound output, the software identifies where certain frequencies are boosted or cancelled out by the room. It then applies an inverse filter to "flatten" the response.
- Impulse Response (Phase Correction): This is where Dirac differentiates itself. By correcting the phase, the software ensures that all sound frequencies arrive at the listener’s ears at the same time. This results in what audiophiles describe as "imprecise imaging"—the ability to pinpoint exactly where a guitar, vocal, or drum is positioned in the soundstage.
In a custom installation scenario, where speakers are often hidden in ceilings or walls, the room’s impact on sound quality is significantly amplified. The CI SA2-120 and CI S2, when calibrated with Dirac Live, mitigate these hidden-speaker issues, providing a "transparent" sound that feels as if it is emanating from a high-end, free-standing system.
Voices from the Industry: Official Responses
The collaboration has been met with enthusiasm from both the executive and engineering tiers of both organizations.
Rikard Hellerfelt, VP and Head of Consumer Electronics at Dirac, emphasized the necessity of the technology in modern home design. "Every room shapes sound in ways that even premium audio hardware cannot address on its own," said Hellerfelt during the announcement. "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, echoed this sentiment, highlighting the practical benefits for the integrator. "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."
The Professional Implication: What This Means for Integrators
For the integrator, this announcement is more than a software update; it is a business differentiator. In the competitive world of luxury home audio, the ability to guarantee "concert-hall quality" in a difficult living space is a high-value service.
1. Increased Design Flexibility
Integrators are no longer restricted to installing speakers in "acoustically friendly" locations. With Dirac Live, they can place architectural speakers where the client wants them, and use the software to compensate for the placement, ensuring the sound remains balanced and clear.
2. Solving the "Multi-Zone" Dilemma
In multi-room systems, different zones often have vastly different acoustic characteristics. A kitchen with granite countertops and hard floors will sound radically different from a carpeted, curtained bedroom. The CI SA2-120 and CI S2 allow the integrator to create unique calibration profiles for every single zone, providing a consistent "house sound" regardless of the individual room’s architecture.
3. Scalability and Reliability
The modular nature of the NAD CI series means that systems can start small and grow. Because the Dirac integration is tied to the hardware modules, adding more zones to a home does not mean abandoning the acoustic optimization already established. It allows for a cohesive, professional-grade ecosystem that grows alongside the client’s home.
Conclusion: A New Standard for Custom Install
The introduction of Dirac Live to the NAD CI SA2-120 and CI S2 marks a turning point in the integration market. It bridges the divide between the convenience of distributed, whole-home audio and the uncompromising performance of audiophile-grade components. As smart homes continue to evolve, the focus is shifting toward "invisible" technology that provides visible (or rather, audible) quality.
By prioritizing the acoustic experience through sophisticated digital correction, Dirac and NAD are ensuring that the future of custom installation is not just about connectivity—it is about clarity, balance, and the preservation of the artist’s intent in every corner of the home.
For those attending CEDIA Expo 2026, the results of this partnership are on full display at the Lenbrook Booth 3319. As the industry looks toward the next generation of home audio, one thing is clear: the room is no longer an obstacle—it is an instrument to be tuned.
