High-Performance CD-Player: The TEAC
PD-501HR is a high-performance CD player with 20-80kHz of frequency
response, 116dB of S/N ratio, 118dB dynamic range, and 0.004% of THD on PCM
playback. The PD-501HR supports playback of PCM/WAV files on recordable CD
discs, plus PCM/WAV and DSD music files on recordable DVD discs.
- Disc Compatibility: The TEAC PD-501HR supports CD-DA, CD-ROM,
CD-R, and CD-RW discs (ISO 9660 Level 1/2/Joilet). The PD-501HR also
supports DVD-ROM, DVD-R/RW, and DVD+R/RW discs (UDF). Only 12cm discs can be
used. DVD-Video and SACD discs are not supported.
- Supported Audio Formats: The TEAC PD-501HR disc
player supports CD-Audio (44.1kHz; 16-bit) on CD-DA discs, as well as PCM/WAV
(44.1/48kHz; 16 or 24-bit) on CD-ROM/-R/-RW discs. It also supports PCM/WAV (44.1/48/88.2/96/176.4/192kHz; 16 or 24-bit) and DSD (2.8/5.6MHz)
music files on DVD-ROM/-R/-RW/+R/+RW discs. Not compatible with MP3, WMA, AAC, FLAC, and other audio files not
Note: Discs that contain more than 999 folders and files in total might
not play back properly.
Pure Mode: Conventional DSD processors convert PCM files prior to converting to an
analog signal. The PD-501HR employs a "Pure Mode", processing DSD into an analog
signal directly. This lets you enjoy pure DSD sound that normal PCM-conversion
VACS (Vibration Acoustic Control Structure): While reading signals
from an audio disc, vibrations may cause a read error and negatively affect the
sound quality by missing some of the original data on the disc. To eliminate
vibrations and reach perfect data reading, the PD-501HR employs a unique
vibration control mechanism, VACS, for a smooth rotation. After dozens of
evaluation tests the VACS instrument was chosen and fixed to the drive of the
unit in order to achieve the best possible performance.
Cirrus Logic CS4398 DAC: A celebrated CS4398 24-bit/192kHz
DAC by Cirrus Logic is
utilized to achieve 118dB of dynamic range. The CS4398 DAC also employs un-damped
volume control and a Mismatch Shaping Technology to eliminate distortion caused
by capacitor mismatching.
JRC NJM5532 Operational Amplifier: The field-proven and well-reputed
JRC's NJM5532 operational amplifier has been applied to the analog circuits.
6-Layer Circuit Boards: In order to reduce the signal paths throughout
the circuits, each part has been carefully laid out on 6-layer glass-epoxy
motherboards. This design reduces and simplifies the signal paths and helps
improve the sound quality.
Separated Power Supplies: Separate power supplies for the digital and
analog sections help prevent digital noise that can leak across the sections
over the current. Schottky Barrier Diodes are also employed on the rectifier
circuit to supply cleaner current by eliminating rectification noise.
Analog & Digital Outputs: The PD-501HR is fitted with both analog and
digital outputs. It features on analog stereo output (RCA), one optical
(toslink) digital output, and one coaxial (RCA) digital output.
Note: The sampling frequency and bit rate used by the digital outputs
(COAXIAL and OPTICAL) are the same as for the playback source. During DSD
playback or CD/PCM playback in pure mode, however, nothing is output from the
Well-Designed Controls: Spun metal finished transport buttons with
short stroke and an easy-to-recognize toggle switch gives the user assured
operation. Even the remote control is designed with an aluminum facia on top for
a luxurious finish.
Full-Metal Construction: Not only the front panel, both side and top
panels are made of aluminum and attached to a robust steel chassis. These heavy
parts eliminate vibrations and allow all internal circuits to always perform
under stable conditions. An A4-sized body allows users to place the unit in
small spaces. The PD-501HR defines a new standard that fits all modern interior
with great space-saving design and a timeless presence.
Green Technology: The PD-501HR maintains low power consumption without
sacrificing sound quality. With a 11W of power consumption, a selectable power
saving mode and 0.1W of power consumption during standby, the PD-501HR can truly
be called "green technology".
Auto Power Save: The unit will automatically enter standby mode if
there is no audio output for 30 minutes.
