506 20-bit CD Player  
Meridian take the 506  
one step closer to the  
aw ard w ining  
standard of the 508  
20-bit CD player.  
The new 20-bit 506  
uses the same D-A  
conversion  
technonogy  
developed w ith  
Crystal Semiconductor  
for the 508 CD Player  
but w ithout the  
added expense of  
precision re-clocking.  
Crystal Semiconductor, helping them to  
develop the ultimate converter. The  
resulting device, has the required 20-bit  
analogue and digital parameters.  
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  
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.  
recognized to make the best sounding  
CDs -- hundreds of which are now  
available.  
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.  
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.  
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 discbefore it is  
decoded.  
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  
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.  
Over a period of three years, Meridian  
has worked closely with chip-maker
