NAD Electronics has added Dirac Live Room Correction support to two modules in its CI Modular Series, the CI SA2-120 BluOS Streaming Amplifier Module and the CI S2 BluOS Streaming Module, giving custom installers a certified path to room-optimized sound on NAD’s modular custom-install platform, without swapping in separate outboard processing.
What’s changing?
Dirac announced the certification at CEDIA Expo 2026, confirming that the CI SA2-120 and CI S2 now support Dirac Live Room Correction Full Bandwidth. The technology corrects both the magnitude and phase of a system’s sound response, targeting the acoustic problems that show up once hardware meets a real room, chiefly uneven frequency response and imprecise imaging. For integrators, that means one more calibrated tool inside a modular platform that was already built to scale from a single room to a full, multi-zone install.
What’s inside the CI Modular Series?
The CI SA2-120 pairs amplification and BluOS streaming in a single, space-saving module built for single- or dual-zone rooms. The CI S2 skips the amplifier and instead delivers two independent zones of BluOS streaming for systems where amplification already lives elsewhere in the rack. Both sit inside NAD’s CI Modular Series alongside the CI PA4-60, a four-channel power amplifier for larger distributed systems.
Certifying Dirac Live Room Correction across the SA2-120 and S2 means integrators can standardize on the same calibration workflow whether or not a zone needs its own amplification. That matters most in whole-home projects, where a living room might run off the SA2-120’s built-in amplifier while a patio or bedroom zone feeds an existing amp through the S2, yet both can now be measured and corrected the same way. It also means fewer separate tools to carry on-site and fewer calibration profiles to manage across a project.
Why add Dirac now?
“Every room shapes sound in ways that even premium audio hardware cannot address on its own,” said Rikard Hellerfelt, VP and Head of Consumer Electronics at Dirac, in the announcement. NAD’s Custom Install Product Manager Peter Gibb made a similar point from the manufacturer’s side, saying Dirac Live Room Correction pairs the modular platform’s flexibility with room optimization that holds up across a wide range of spaces and system configurations. NAD has been extending Dirac Live Room Correction across more of its lineup this year, having already brought Dirac Live Bass Control to the M33 V2, M10 V3 and C 658 earlier in 2026. Rolling the same room-correction technology down into the CI Modular Series extends that strategy from flagship components into the custom-install products integrators specify most often.
Pricing and availability
Dirac Live Room Correction Full Bandwidth for the CI SA2-120 and CI S2 is available to purchase now through NAD. Neither module carries a public consumer price, in keeping with NAD’s custom-install channel, where CI Modular Series components are typically quoted and sold through integrators rather than listed at retail. Integrators who need to run the measurement themselves can also pick up NAD’s Dirac Room Calibration Kit, which bundles the equipment for precise Dirac Live measurements in the field. NAD is showing the CI Modular Series, including the new Dirac Live Room Correction support, at CEDIA Expo 2026, running September 2-4 at Lenbrook’s booth in Denver.
