Special Design Features

Rugged Build

 

Mechanical strength has been a hallmark of Perreaux products since the

 

Quality

 

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

 

There is a separate regulated power supply for each section of the CD player.

Regulated

 

One positive supply and one negative supply for the sensitive analog output

Power

 

stage, another one for the DAC section, another for the clock generation of the

Supplies

 

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.

Dual 20-bit

 

The ECD2’s precision transport is backed up by Burr Brown’s PCM1732 digital

Burr Brown

 

to analog converter, featuring HDCD decoding. The dual 20-bit, multi-level

DAC

 

Delta-Sigma operation with 8x oversampling ensures the ECD2 will deliver a

 

 

high level of audio performance.

HDCD®

 

High Definition Compatible Digital™ (HDCD®) is an encoding technique that

Decoding

 

allows a CD to have greater dynamic range, focused 3D soundstage, reduced

 

 

distortion, and increased detail. When playing HDCD encoded discs, the ECD2

 

 

can reproduce as much as 20-bit dynamic range. HDCD discs are identified by

 

 

an HDCD logo on the package.

 

 

No user action is required to play an HDCD encoded disc. The player

 

 

automatically senses HDCD encoding and enables the necessary circuitry. The

 

 

HDCD indicator on the front panel will light to indicate that an HDCD disc is

 

 

being played.
