DENVER, CO — At the 2026 CEDIA Expo, the professional audio landscape witnessed a significant shift in the capabilities of distributed audio systems. Swedish digital audio pioneer Dirac, in collaboration with NAD Electronics, announced the integration of Dirac Live Room Correction into two of the industry’s most versatile components: the NAD CI SA2-120 BluOS Streaming Amplifier Module and the CI S2 BluOS Streaming Module. This development marks a pivotal moment for custom integrators, bridging the gap between high-performance audiophile sound and the complex, often acoustically challenging environments of modern residential design.
Main Facts: A New Standard for Distributed Audio
The core of the announcement centers on the certification of the NAD CI SA2-120 and CI S2 for Dirac Live. By incorporating this industry-leading room optimization software into their Modular Series, NAD and Dirac are empowering professional integrators to deliver studio-quality sound regardless of room dimensions, furniture placement, or architectural quirks.
Dirac Live is widely considered the gold standard for acoustic room correction. It utilizes sophisticated algorithms to analyze the interaction between the speakers and the listening space. By correcting both the magnitude and phase of the sound response, Dirac Live eliminates the muddiness, resonance, and uneven frequency responses that plague most non-optimized rooms.
For the professional integrator, this means that the "variable of the room"—often the most difficult aspect of a project to control—can now be neutralized. Whether the system is installed in a minimalist, glass-heavy living room or a tightly enclosed media space, the CI SA2-120 and CI S2 can now be calibrated to produce a consistent, balanced, and immersive sound signature that remains true to the original recording.
Chronology: The Evolution of the NAD CI Modular Series
The journey toward this integration is part of a broader strategy by NAD Electronics to modernize the custom installation (CI) market. NAD, a brand with a legacy dating back to 1972, has consistently sought to balance the high-performance needs of audiophiles with the practical requirements of modern installers.
- 1972–2020: NAD establishes its reputation through high-fidelity stereo and home theater components. As the CI market grows, the company pivots to develop solutions specifically for rack-mounted, multi-room, and high-performance residential projects.
- 2023–2024: The launch of the NAD CI Modular Series. This architecture was designed with a "plug-and-play" ethos, allowing integrators to scale systems by swapping modules, thereby simplifying inventory and field deployment.
- 2025: As multi-room audio demands increased fidelity, NAD and Dirac began exploring ways to integrate digital signal processing (DSP) deeper into the CI lineup.
- September 2026: At the CEDIA Expo in Denver, the official certification of the CI SA2-120 and CI S2 for Dirac Live is announced, marking the first time this level of acoustic optimization has been brought to these specific modular streaming platforms.
Supporting Data: Understanding the Acoustic Challenge
To appreciate the significance of this integration, one must understand the physics of residential sound. In any domestic environment, sound waves reflect off hard surfaces (walls, windows, floors) and are absorbed by soft surfaces (upholstery, rugs). This results in "standing waves," "room modes," and phase distortions that can severely degrade audio quality.
The Physics of Correction
- Frequency Response Smoothing: Without correction, a system might exhibit "peaks" (too much bass or treble) and "dips" (a lack of presence in the midrange). Dirac Live maps these peaks and dips and creates a corrective filter that levels the playing field.
- Phase Correction: This is where Dirac truly differentiates itself. Even if a speaker is technically "accurate," the timing at which sound arrives at the listener’s ear can be disrupted by reflections. Dirac Live corrects the arrival time, ensuring that the soundstage is cohesive and the "imaging"—the ability to locate instruments in a virtual space—is surgically precise.
- Modular Scalability: The NAD CI SA2-120 offers high-quality amplification paired with BluOS, while the CI S2 provides the streaming backbone for multi-zone setups. By adding Dirac Live to these units, the entire chain of audio—from source to amplification to room interaction—is optimized.
Official Responses: Insights from Industry Leaders
The collaboration between Dirac and NAD represents a synergy between software engineering and hardware design.
Rikard Hellerfelt, VP and Head of Consumer Electronics at Dirac, noted the necessity of this technology in today’s modern homes: "Every room shapes sound in ways that even premium audio hardware cannot address on its own. 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, emphasized the practical benefit for the integrator’s workflow: "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: The Future of Professional Installation
The introduction of Dirac Live to the NAD CI Modular Series carries several long-term implications for the audio industry:
1. Elevating Expectations for Multi-Room Audio
Historically, "whole-home audio" was often associated with background music—systems that were convenient but rarely high-fidelity. By bringing Dirac Live to modular streaming amps, NAD is signaling that the expectation for multi-room audio is rising. Homeowners now expect the same clarity in their kitchen or bedroom as they do in their dedicated listening room.
2. Streamlining the Integrator’s Workflow
Professional integrators operate on tight margins and strict timelines. Traditionally, if a room sounded poor, the integrator would have to rely on physical acoustic treatments, which are expensive, aesthetically intrusive, and time-consuming to install. Dirac Live offers a digital solution that is repeatable, efficient, and highly effective, allowing integrators to "tune" a room in a fraction of the time it would take to install physical panels.
3. A Competitive Edge in the Luxury Market
For high-end residential projects, the ability to promise "perfect sound" is a significant competitive advantage. Integrators who utilize these NAD modules with Dirac Live can provide documentation of the calibration (the before-and-after measurements), offering clients tangible proof of the value provided.
4. Continued Growth of the BluOS Ecosystem
By integrating this feature into the BluOS platform, NAD is strengthening the ecosystem. BluOS has already become a favorite among audiophiles for its high-resolution streaming capabilities. Adding professional-grade room correction makes it a complete, end-to-end solution for the most demanding installations.
Moving Forward: Access and Availability
For those attending the CEDIA Expo 2026, the NAD and Dirac teams are demonstrating the full calibration process at the Lenbrook Booth (3319).
For existing owners or those looking to implement this in new projects, Dirac Live Room Correction Full Bandwidth is available as an upgrade through the Dirac website. To perform the calibration, the NAD Dirac Room Calibration Kit—which includes a high-precision measurement microphone and necessary hardware—can be sourced directly through NAD.
As the industry continues to move toward a marriage of high-performance hardware and intelligent software, the NAD-Dirac partnership stands as a blueprint for the future of custom installation. It is no longer just about selling speakers and amplifiers; it is about delivering an acoustic experience that is tailored, precise, and profoundly immersive. Through this integration, NAD and Dirac have ensured that the sound of the future is not just loud or convenient—it is perfect.
