synchronized.
By the use of upsampling the stream of information is independent of the 44.1 kHz clock pulse. Intermediate
storage in a buffer followed by its chronologically correct output ensures that the converter is not affected
by drive induced jitter.
The front of the C02 is clearly defined and contains all of the operating elements necessary for the basic
functions. This permits clarity and simplicity of operation. Of course the C02 can do much more: Title pro-
gramming and special functions, such as the ability
to
switch the digital filter, are available through the remo-
te control.
MECHANICAL CONSTRUCTION
The modules, power supply, drive controller, output stages are situated on separate IC boards. This reduces
mutual influence to a minimum. The casing of the C02 is manufactured from magnetically protecting steel
plate. The built-in power transformers are of the low-scatter toroidal type.
The output sockets of the C02 have surface treated contact areas to promote good contact and durability.
Epoxy resin circuit boards and the use of selected brand named, high quality components ensure that you
will have a lot of enjoyment from your AVM C02.
THE POWER SUPPLY
In the same way that we believe that separation of the drive and the O/A converter provides an optimal
tonal solution due to the absolute freedom from reaction it is also our opinion that the individual modules
of a CO player should not mutually influence each other. For the reason the C02 has two power supplies
that are fed from low impedance toroidal transformers. One is mainly for the supply of the servo electro-
nics or alternatively the audio digital section whereas the other delivers current to the O/A converter and
output stages
THE DIGITAl SECTION
The output signals of the drive are received by the sampling rate converter CS 8420.This increases the pulse
rate of the data bits from 16 Bit/44.1 kHz to 24 Bit/96 kHz or alternatively 24 Bit/88.2 kHz. This integrated
circuit removes any existing jitter completely from the signal (up to the physically unavoidable minimum)
before it passes it to the digital filter.
The digital filter situated behind the sampling rate converter ensures that unwanted frequency components
(aliasing) are removed from the signal flow. For this purpose two filter variations are available. In the selec-
tion "sharp" the signal amplitude falls steeply at the end of the transmission range whereas the selection
"slow" causes a flatter fall off of the amplitude towards the cut-off region. With both variants the complete
audio bandwidth is retained so that you can adjust the tonal qualities of the C02 to your listening prefe-
rences.
