NAD C390DD graphite

The NAD C 390DD is not only a new concept in amplification, but also in audio system architecture. This integrated digital amplifier delivers 160 W per channel with Power Drive technology. The digital technology provides dynamic and detailed sound.

Like the M2, the C 390DD has no analog stages in the signal path. Three cards can be added to this system, integrating 3 HDMI inputs compatible with 3D and ARC using the DD-HDMI-1 module or an analog input module with RCA, phono, and XLR using the MDC DD AP-1 module. It also features an asynchronous USB for streaming music up to 24-bit/96 kHz sampling, while the other digital inputs support up to 24-bit/192kHz.
