Dirac has unveiled that the NAD Electronics CI SA2-120 BluOS Streaming Amplifier Module and CI S2 BluOS Streaming Module have been certified to support Dirac Live Room Correction, expanding room optimisation capabilities across NAD’s custom installation range.

The certification was announced at CEDIA Expo 2026 and gives professional integrators access to Dirac’s room correction technology across the NAD CI Modular Series. The modular platform is designed for scalable custom installation projects, with compact components that can be combined to suit different system configurations.

Dirac Live corrects both the magnitude and phase of a system’s sound response to address acoustic issues created by the interaction between an audio system and its environment. According to Dirac, this can improve frequency response, bass accuracy, imaging and overall soundstage coherence.

“Every room shapes sound in ways that even premium audio hardware cannot address on its own,” Dirac vice president and head of consumer electronics Rikard Hellerfelt says.

“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.”

The CI SA2-120 combines amplification and BluOS music streaming in a compact format for single and dual-zone applications, while the CI S2 provides two independent BluOS streaming zones for multi-room systems. The range also includes the CI PA4-60 four-channel power amplifier for larger distributed audio installations.

“For custom integrators, every project presents a unique acoustic environment,” NAD Electronics custom install product manager Peter Gibb says.

“Bringing Dirac Live Room Correction to the CI SA2-120 pairs the flexibility of our modular CI platform with powerful room optimisation, helping integrators achieve exceptional, consistent sound across a wide range of spaces and system configurations.”
