The NAD MDC2 BluOS D Module is a versatile platform that allows for a wider range of upgrade options for the NAD C 399 Hybrid Digital DAC Amplifier and future MDC2-enabled components. The module includes Dirac Live Room Correction, which analyzes room acoustics and corrects peaks and dips at frequencies up to 500Hz, resulting in vastly improved bass clarity, imaging, and timbral accuracy on all sources. NAD MDC2 BluOS D Module MDC2, the second generation of their innovative Modular Design Construction platform. The all-new MDC2 architecture allows signals to be passed back and forth between module and host component. This opens a far wider range of upgrade options for the new NAD C 399 Hybrid Digital DAC Amplifier and future MDC2-enabled components. Dirac Live Room Correction The weakest link in most sound systems is the listening environment. Room modes can cause boomy, uneven bass response; and reflections of sounds from room surfaces can smear transients and disrupt stereo imaging. Dirac Live analyzes room acoustics, and then uploads compensation filters to the MDC2 BluOS-D module. The MDC2 BluOS-D module corrects peaks and dips at frequencies up to 500Hz, which is the area where room modes are most problematic; a license for the full-bandwidth version of Dirac Live is available as an option. Dirac Live also optimizes impulse response by analyzing how sounds are reflected off room surfaces. With Dirac Live enabled, listeners will enjoy vastly improved bass clarity, imaging, and timbral accuracy on all sources. The MDC2 BluOS-D module can store up to five Dirac profiles for different listening positions or room conditions—for example whether the drapes are open or closed. The MDC2 BluOS-D module is NAD’s first module to enable Dirac Live room correction on a two-channel component—a testament to the versatility of the MDC2 platform. A calibrated microphone is included for performing room measurements.
