NAD Electronics has announced that its C 658 BluOS Streaming DAC will soon be equipped with room correction software from Dirac Research, and an update is scheduled on or around 10th June, 2019.
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.
“Speaker placement is hard to get right,” explained Cas Oostvogel, NAD Electronics Product Manager. “You are limited by practicalities like leaving doorways clear, placement of other furniture, and location of electrical outlets. Dirac Live essentially does the heavy lifting to make your music sound as if your speakers were ideally placed.”
The C 658 includes a microphone so users can calibrate a listening environment using Dirac’s proprietary app, available for desktop, iOS, and Android devices, and up to five 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 to select filters, adjust subwoofer crossover settings, or disable Dirac.
Dirac Live will make these compensations up to 500 Hz, and users interested in room correction across the full frequency range can upgrade to Dirac Live Full. You can get more information on the NAD Electronics and Dirac websites.
