Special Design Features
Rugged Build
Quality
M echanical strength has been a hallmark of Perreaux products since the
company first started production back in 1974. The concept behind the physical
design and construction is that each structural member should contribute to both
rigidity and performance.
Multiple
Regulated
Power
Supplies
There is a separate regulated power supply for each section of the CD player.
One positive supply and one negative supply for the sensitive analog output
stage, another one for the DAC section, another for the clock generation of the
DAC section and a further supply for the microcontroller and display. The
advantage of this is that there is complete isolation from stage to stage, ensuring
the analog section is completely free from digital noise.
Burr Brown
DAC
The CD1’s precision transport is backed up by a Burr Brown (Texas
Instruments) digital to analog converter. M ulti-level Delta-Sigma operation with
8x over-sampling ensures the CD1 will deliver a high level of audio
performance.
Balanced
Analog
Output
The CD1 offers a balanced analog output, providing improved noise rejection
and cancellation.
