RDD-1580 uses two WM8740s in a complementary configuration that reduces noise and distortion well beyond that which a single converter can provide.
  • Intermodulation Distortion (60Hz:7KHz): <0.004%
  • Input Sensitivity /Impedance: 0 dBFs /75 ohms
  • Dimensions (W x H x D): 431 x 55 x 316mm
Brand: Rotel
Model: RDD-1580
  • At its heart, the RDD-1580 makes use of Wolfson’s extraordinary WM8740 stereo digital-to-analogue converter. But where competitive products use only one of these converters to handle two channels.
  • Another RDD-1580 advantage lies in its input flexibility. A front panel USB input supports Apple iPod®, iPhone® and iPad® as well as streaming via Bluetooth with the included adapter. The rear panel PC-USB input will support files up to 24 bit/192kHz in asynchronous mode.
  • Two sets of rear panel RCA-style coaxial and TOSlink optical digital inputs are optimized for LPCM data streams in any common format from the CD’s 16-bit/44. 1 kHz standard to high definition sources with 24-bit/192 kHz audio data.
  • As you might expect, a Rotel-designed and manufactured toroidal transformer sits at the foundation of the RDD-1580’s well-regulated power supply.
  • Advanced Slit-Foil capacitors provide storage capabilities that ensure substantial and stable operating voltages and current to all circuit stages.
  • The carefully tuned analogue section is another example of Rotel’s vaunted Balanced Design approach in which specifications alone do not dictate which internal parts are used.
  • Rather, extensive listening tests under controlled conditions provide the final “ears-on” determination. After this, the entire circuit is tuned to extract the most sonically accurate signal possible.
  • The RDD-1580 provides both single-ended and balanced outputs with RCA and XLR connectors respectively.
  • Recognizing today’s changing tastes in audio sources, the RDD-1580 even provides high-current charging capability (2.1 amperes) for an iPad or similar device to reduce clutter and increase needed desk space even while expanding your audio source options.
  • Built with yesterday’s concern for stunning sound quality but designed for today’s increasingly complex digital world, the RDD-1580 offers a first rate combination of superior sonics and convenience.
