CD21 COMPACT DISC PLAYER USER GUIDE
INTRODUCTION
Welcome to the Primare CD21 Compact Disc Player!
This chapter introduces you to its key features, and ex-
plains how you can use it to achieve superb sound from
your CD collection.
Every component of the CD21, from the CD transport to
the audio output stage, has been designed to achieve the
highest possible audio performance.
Top of the range Ultra Silent transport mechanism
The Primare CD21 Compact Disc Player uses an advan-
ced DVS mechanism. A precision crystal clock oscillator is
used in addition to the use of jitter correction Burr-Brown
DIR1703 to ensure low jitter, for excellent audio perfor-
mance.
Precision digital to analogue conversion
Digital to analogue conversion is performed by two 24 bit
Burr-Brown PCM 1738 D/A converter and fi lter, capable
of handling up to 24 bit input data at a 96kHz sampling
rate. They are confi gured in an internally balanced topo-
logy to perform a THD cancellation process. In addition
to providing standard RCA audio outputs the CD21
includes a gold-plated S/PDIF digital output, an optical
TOS-link, and advanced AES/EBU.
Welcome to the CD21 Compact Disc Player
No compromise power supply for the highest
possible performance
The Primare CD21 Compact Disc Player uses eight
separate isolated power supplies for the digital, analogue
circuits, and transport mechanism, for maximum
isolation. For the analogue part, discrete and ultrafast
regulation is used.The result is an extremely high signal
to noise ratio, allowing you to take full advantage of the
dynamic range possible with CD.
Careful design for mechanical stability
As with all Primare units, the CD21 Compact Disc Player
is housed in an alloy heavy gauge steel chassis, which pro-
vides strength, rigidity, and screening, while being effective
at damping vibrations from external sources. The front
panel design isolates the display circuitry from the audio
circuitry to avoid interference.
