The culmination of more than three decades of Rotel CD technology refinement, the RCD-1570 is the flagship CD player in Rotel‘s new 15 Series, combining a wealth of features to reveal even the subtlest nuances in your CDs. For example, the CD player’s Wolfson WM8740 digital filter/stereo digital-to-analogue converter processes digital signals up to 24-bits in length at sampling rates from 8kHz to 196kHz, ensuring reference levels of reproduction under all circumstances. The RCD-1570’s slot-loading disc transport design isolates the CD itself from potentially destructive vibration modes that may affect musical definition, while simplifying the front panel’s appearance.
Those who haven’t heard Rotel’s RCD-1570 might
believe that there’s nothing new in CD players.
Those who have heard it tell an entirely different story.
Since 1982, when the CD was introduced, Rotel has
been refining technology and evolving circuitry to bring
you extraordinary sound. The RCD-1570, the
outstanding CD player in Rotel‘s 15 series, focuses
careful refinements to reveal even the most subtle
nuances buried in a CD’s pit spiral.
One of the RCD-1570’s most important features is the
Wolfson WM8740 digital filter/stereo digital-to-analog
converter. Originally developed for high resolution
sources, it is the product of extensive research and real
world testing and processes digital signals up to 24-bits
in length at sampling rates from 8 kHz to 192 kHz.
While word lengths and sampling speed may seem
excessive for CDs delivering data at far lower rates,
this high speed facility adds reserve capability to ensure
proper reproduction under all circumstances. As the
most crucial link between a CD’s digital data and the
analog world in which we listen, this converter boasts
significant attributes in addition to its superb high
resolution capabilities.
Another advance is the RCD-1570’s slot-loading disc
transport. In addition to mechanical simplicity and
improved reliability, this design isolates the CD itself
from potentially destructive vibration modes that may
affect musical definition. And from a purely aesthetic
viewpoint, it adds elegance by simplifying the front
panel’s appearance.
The post-converter analog circuitry benefits from Rotel‘s
decades-long experiences in crafting the finest sounding
pathway from the D/A’s internal output to single and
balanced rear panel connectors that bridge the gap
between the RCD-1570 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.

XLR connectors provide balanced outputs,
long recognized for their superior noise-rejecting
characteristics while high quality RCA connectors
provide an easy pathway to the myriad of components
with single-ended inputs.
This is all part of Rotel’s long-proven Balanced
Design Concept. It’s yet another way of assuring
you that the RCD-1570 evidences a level of attention
that will make it part of your reference-level music
system for years to come.
