The NAD C 389 is a stereo integrated amplifier with a built-in DAC. It uses NAD's customized HybridDigital UcD output stages in a balanced bridge configuration, powered by a switch-mode power supply. It delivers 130 watts per channel continuous into 8 or 4 ohms, with 210 watts of transient power per channel.
The ESS SABRE ES9028 DAC decodes 32-bit/384kHz digital audio from the optical, coaxial and HDMI eARC inputs. The HDMI eARC input connects to a TV for uncompressed stereo sound, with TV remote volume control and CEC power synchronization. A moving magnet phono input includes an infrasonic filter that removes vinyl warp rumble without reducing bass.
Two MDC2 expansion slots accept the optional MDC2 BluOS-D module, which is sold separately. The module adds 24-bit/192kHz multi-room streaming over Wi-Fi or Ethernet with BluOS, Apple AirPlay 2 and Roon Ready. It also adds Dirac Live room correction, with an included measurement microphone. The amplifier has A and B speaker outputs, two subwoofer outputs and a front-panel headphone jack.
