Myy samanlainenKuvaus
The C 390DD is a stereo integrated amplifier with a built-in digital-to-analogue converter. Its digital inputs are coaxial, optical and USB, and they accept sample rates from 32 kHz to 192 kHz. Continuous output is 150 W or more into both 8 ohm and 4 ohm loads, with a stated dynamic power of 160 W at 8 ohm and 350 W at 4 ohm.
Measured figures include rated distortion of 0.005% (20 Hz to 20 kHz), a signal-to-noise ratio above 95 dB (A-weighted), a damping factor above 800 and channel separation above 90 dB. Maximum output current is over 18 A. Idle power draw is 100 W and standby consumption is below 0.5 W.
The unit measures 435 x 132 x 388 mm and weighs 7.7 kg. The maker's downloads list a data sheet, manuals in several languages, firmware for the amplifier and for its optional MDC HDM-2 module, BluOS release notes, and USB audio drivers for Windows. The product is marked as archived and no longer sold by the maker.
