NAD C 658 BluOS Streaming DAC to Add Dirac Live

Arriving in June 2019, the streaming DAC preamplifier to be equipped with room correction software.

NAD Electronics has announced that its C 658 BluOS Streaming DAC will soon be equipped with room correction software from Dirac Research. With a coming software update scheduled on or around June 10, 2019, Dirac Live will be available to all C 658 users.

Dirac Live measures the energy and time it takes for both direct and reflected sound waves to travel from the speakers to a user-defined listening area from which it calculates precision filters to counteract the negative. The result is a near-perfect compensation of the room’s acoustic anomalies without changing the inherent sound characteristics of the audio system.

The C 658 includes a microphone so users can calibrate their listening environment using Dirac’s proprietary app, available for desktop, iOS, and Android devices. Up to five different listening profiles can be stored.

Tone and room correction controls can be accessed with the Dirac app, while the BluOS Controller app contains basic controls, allowing a user to select filters, adjust subwoofer crossover settings, or simply disable Dirac.

Dirac Live will make these compensations up to 500 Hz. Users interested in room correction across the full frequency range can upgrade to Dirac Live Full.
