Background
It has become possible, principally

through the mastering technologies of

advanced psychoacoustic-based noise-

shaping, to make compatible CDs with

an effective dynamic range in excess

of 19 bits. Meridian is the leader in

this field, and the Meridian 518

Mastering Processor is widely

recognized to make the best sounding

CDs -- hundreds of which are now

available.
In order to get the best from this

compatible mastering process, the CD

player needs to have considerably

higher precision than was thought

necessary some years ago. For

example, to obtain the best sound

from these ‘super CDs’ a player need,

not only a D/A converter of more than

19 bits' precision, but also a DSP filter

whose internal arithmetic exceeds 20

bit precision.
Meridian 506 20 bit CD player
Built as one of the world-famous 500-

Series, this latest CD player from

Meridian sports the same D/A

converter as used in the 508 but

without precision re-clocking
Over a period of three years, Meridian

has worked closely with chip-maker

Crystal Semiconductor, helping them to

develop the ultimate converter. The

resulting device, has the required 20-bit

analogue and digital parameters.
The unique Meridian drawer system

combines the user benefits of tray-

loading with the important

performance benefits of top-loading.

The pick-up mechanisms use a carbon

and glass-fiber anti-vibration disc clamp.
The 506 uses a Meridian CD transport

that gives all the play ability advantages

of a linear 3-beam pickup optimized for

high-speed data recovery, with the

famous Focault focus arrangement that

gives adjustment-free setting, long life

and great sound.
This CD transport uses in-house control

software that, amongst its many

features, adapts the player to the

parameters of each CD. The laser pick-

up uses a radical, proprietary analogue-

processing system that de-jitters the

data coming from the disc before it is

decoded.
Contrary to market trends, Meridian

refuses to compromise in the error-

correction and digital signal processing

capability of their CD players. The 506

uses a state-of-the-art decoder IC that

provides an exceptional ability to

correct disc defects.

Meridian take the 506

one step closer to the

award wining

standard of the 508

20-bit CD player.

The new 20-bit 506

uses the same D-A

conversion

technonogy

developed with

Crystal Semiconductor

for the 508 CD Player

but without the

added expense of

precision re-clocking.
