RDD-1580

http://www.rotel.com/product/rdd-1580
Rotel’s new digital-to-analog converter envelops the listener in the most accurate audio reproduction possible from any digital source, whether it be legacy PCM sources or the latest digital file formats.

At its heart, the RDD-1580 makes use of Wolfson’s WM8740 stereo digital-to-analog converter. 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 audio up to 24-bit/192kHz in asynchronous mode. Two sets of rear panel RCA-style coaxial and optical digital inputs are optimized for LPCM data streams. This includes CDs 16-bit/44.1kHz standard up to high definition sources with 24-bit/192kHz audio data.

A Rotel-designed and manufactured toroidal transformer sits at the foundation of the RDD-1580’s 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 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 while expanding your audio source options.

Built for stunning sound quality, but designed for today’s ever-increasing digital world, the RDD-1580 offers a first rate combination of superior sonics and convenience.

Rotel Stereo Preamps

RC-1572

http://www.rotel.com/product/rc-1572
Among many refinements, the RC-1572 utilizes relay switching for analog sources instead of an IC based switch to maintain the integrity of the signal path for RCA, phono and XLR inputs.

The RC-1572 stereo preamplifier is also extremely flexible. Four digital inputs (2 coax and 2 optical), plus the rear PC-USB handle digital sources up to 32/384 resolution. The 4 inputs are designed for sources such as TV set-top boxes, flat panel TVs or Blu-ray players for stunning playback. Importantly, it is possible to fix the level and set an auto-on option with digital inputs for use with devices that provide their own volume control for convenient “hands-off” use.The PC-USB input supports DSD signals. Integrated Bluetooth aptX is provided. Analog inputs include balanced XLR connectors, perfect for connecting the RCD-1572 via its XLR outputs, in addition to four pair of conventional RCA inputs. A moving magnet phono stage rounds out the source capability. XLR and single ended outputs are provided along with a mono subwoofer output, as are two 12-volt triggers to control on/off operation of an amplifier and/or other components. For custom integration, control options include RS232 on a standard DB9 connector, as well as an Ethernet port for IP control and software updates.

RCD-1572

http://www.rotel.com/product/rcd-1572 
One of the RCD-1572’s most important features is the Wolfson WM8740 digital filter/stereo digital-to-analog converter processes digital signals up to 24-bits in length at sampling rates from 8 kHz to 192 kHz.

The post-converter analog circuitry benefits from crafting the sounding pathway from the DAC’s internal output to RCA and XLR rear panel connectors that bridge the gap between the RCD-1572 and down-stream components. All circuit components – resistors, capacitors, inductors – are chosen only after their positive contribution to sound quality were quantified and verified qualitatively by extensive listening sessions.

All of these circuits draw on a power supply based on an oversized custom Rotel-designed and precision-manufactured toroidal power transformer that, in turn, feeds precise rectifiers, tight-tolerance voltage regulators, and advanced Slit-Foil low-ESR storage capacitors, all globally sourced to ensure musically accurate operation under even the most demanding conditions.
