Rotels new digital-to-analogue converter envelops the
listener in the most accurate audio reproduction possible
from any digital source, whether it be legacy PCM sources
or the latest in digital file formats.
The RDD-1580 provides a level of performance unheard
of at its price level and is specifically designed to cater
for the growing popularity of high definition digital audio.
At its heart, the RDD-1580 makes use of Wolfsons
extraordinary WM8740 stereo digital-to-analogue converter.
But where competitive products use only one of these
converters to handle two channels, the RDD-1580 uses
two WM8740s in a complementary configuration which
reduces noise and distortion well beyond that a single
converter can provide.
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 supports
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.
This includes CDs 16-bit/44.1 kHz standard to high
definition sources with 24-bit/192 kHz audio data. A Rotel-designed and manufactured toroidal transformer
sits at the foundation of the RDD-1580s well-regulated
power supply. Advanced custom-designed slit-foil
capacitors provide electrical storage capabilities
to ensure substantial and stable operating voltages
and current to feed the critical circuit stages.
The carefully tuned analogue section is another
example of Rotels award-winning Balanced Design
approach where specifications alone do not dictate
which electronic parts are selected. Rather, extensive
listening tests are carried out under controlled conditions
to determine the best way forward. During this time
the entire circuit is carefully tuned to provide sonically
accurate signal reproduction.
The RDD-1580 provides both single-ended and balanced
outputs with RCA and XLR connectors respectively
Recognizing todays 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 while
expanding your audio source options.
Built for stunning sound quality but designed for todays
ever-increasing digital world, the RDD-1580 offers a first
rate combination of superior sonics and convenience.
