THE
CONCEPTOFTHE
EVOLUTION
CD2
The
C02
has been optimizedtoa
sure
and extremely jitter free read
outofthe
digital information
where-
by
the
quantityofinformationisunmistakably definedbythe
CD
format16Bitl44.1 kHzatthe
converter
input.Additional informationinthe
senseofa higher resolutionoran
extended
frequency rangeisnot
achie-
vable. Most
of
the
currently used digitallanalogue (D/A)
converters
are
not
abletocompletely
convert
the
information offered on
the
CDtoanalogue signals for
the
following reasons.
A n
in
built problem with systems when reconverting digital informationisthe
so-called quantization noise.
This results from slight inaccuracies displayed
by
the
discrete existing valuesincomparisontothe
original
analogue signal.
With
the
CD
format
these
inaccuracies are definedbythe16Bit
word
breadth,inother
words
that
during
the
productionofthe
CDapendant
with a maximum resolutionof65,536 stagesisatta-
ched
to
the
analogue signal.Ifan analogue signal lies between
these
stages a principle
error
occurs
during
recording which limits
the
achievable tonal quality.
The
recordingistherefore
produced with a far
greater
resolution than can actually be
storedonthe
CDinan
attempttominimize
the
error.
The
remaining inaccuracies are randomly distributed and
become
apparent during re-conversionasan
even-
ly
distributed noise
over
the
useful frequency band.This noise limits
the
dynamic characteristics approaching
the
lower ranges and ieadstoconcealment of
the
fine information held on
the
CD.Ifthe
digital signal
is
upsampledtoa higher frequency
priortore-conversion
the
quantization noiseisdistributed
overagreater
frequency spectrum. However because
the
noise energy remains
constant
the
greater
noise band width leads
to
a lower noise level. A large
partofthe
noiseisnow situated outside
the
relative audio frequency band
and can be filtered
out
relatively easily.This
does
not
mean
that
new informationisgained
however
that
part
of
the
information
that
was previously coveredbythe
noise becomes audible.
For this reason
the
digital signal of
the
C02isupsampledto24 Bitl96 kHz
priortothe
DIA conversion.
The
enlargementofthe
word
breadthto24 Bit leadstoa clear reductionofthe
quantization noiseofthe
DIA
converter.
At
the
endofthe
frequency range
the
low frequency signals must be filteredtoseparate
aliasing
compo-
nents from
the
useful signal. The filtration causes drastic phase shifts
under
normal circumstances which can
be detrimental
to
the
spatial image.Aliasing
components
become
apparent from a frequency
of22kHz with
standard
CD
format.This makes
the
employmentofsteep sloop analogue filtersofa
high
order
necessary
which lead
toanincreaseofthe
phase- and amplitude distortions.Incomparison upsamplingto96 kHz
aliasing
components
first
become
apparent
beyond 48 kHz.This means
that
impulse optimized filters can
be
utilized which
treat
the
analogue signal with
great
care
within
the
audible range. Phase- and amplitude
distortions
do
not
occur
and
the
tonal image remains correctly pitched and stable.
Special attention was paid
to
the
minimizationofjitter. Deviationinthe
pulse
rateofthe
digital signal
is
knownasjitter.These deviations, which are for
the
most
part
causedbythe drive, resultsinthe
offered infor-
mation being processed
at
the
wrong
moment
of time.This causes distortion and noiseinthe
analogue range
thatintheir
turn are responsible for faded and slightly roughened tonal characteristics.
There
are many ways of ensuring
that
the
offered informationisprocessedinits
exact
chronological
sequence.
AVM
has decidedtoproceed
along a radical and uncompromising path.
Allofthe
clock pulse
frequencies
that
are necessary for signal processing are
generatedina special module
thatisnot
timedbya
normal quartz crystal but instead
byahigh
precision
quartz
oscillator. It can be assured through this
that
the
21
relativity of the needed frequencies always remains exactly equal and therefore
all
assemblies are optimally
synchronized.
By
the
use of upsampling the stream of informationisindependent of the
44.1
kHz clock pulse. Intermediate
storage
in
a buffer followedbyits chronologically
correct
output ensures
that
the converterisnot
affected
by
drive induced jitter.
The front of the
C02isclearly 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 separateICboards.This reduces
mutual influence
to
a minimum. The casing of the
C02ismanufactured 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 areastopromote 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 providesanoptimal
tonal solution due
to
the absolute freedom from reaction itisalso
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.
Oneismainly for
the
supply of
the
servo electro-
nics
or
alternatively the audio digital section whereas the
other
delivers currenttothe
O/A
converter and
output
stages
THE
DIGITAl
SECTION
The
output
signals of
the
drive are receivedbythe sampling rate converterCS8420.This increases
the
pulse
rate of the data bits from
16
Bit/44.1 kHzto24 Bit/96 kHzoralternatively 24 Bit/88.2 kHz.This integrated
circuit removes any existing jitter completely from the
signal
(uptothe 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.Inthe 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
C02toyour listening prefe-
rences.
22
Besides this
the
digital filter increases
the
sampling frequencybya factorof8 (oversampling) through
extre-
mely fast calculation of intermediate values,
thereby
permitting
the
analogue filter at
the
converter
output
tobelaid
outinas
considerate a
manneraspossible with regardtophase and amplitude.
All
necessary pulse frequencies are
producedbya mutual,
extremely
precise pulse generator.
The
audio digital informationisavailableinCD
standard
format
(16
Bit!
44.1 kHz)oneachofthe
three
dig-
ital
outputs.
THE
DIGITAl/ANALOGUE
(D/A)
CONVERTER
The
raw data from
the
digital filtersispassed discretely through
separate
channelstothe
D/A
converters.Weinstall only pre-selected Burr-Brown
PCM
1704 converters.This
high
precision parallel con-
verterisconsideredtobe
the
best
product
availableonthe
market. Strict selection
procedures
and careful
laser trimming of
the
converterbythe
manufacturer
ensures
constant
high
tonal qualityofthe
CD2.
THE
ANALOGUE·FILTER
Filtering
the
signals after conversion
ensures
that
unwanted frequency remnants (aliasing, sampling frequen-
cy)
are
removed from
the
converted
audio signal.
We
regard filteringtobe very important.
The
wayinwhich
filters
work
with phase and amplitudeofthe
signals can have serious effectsonthe
tonal qualityofa D/A
converter.
We
have
created
a filter
that
causes no ampiitudeorphase
errors
within
the
audio frequency
range.This was possible because upsampling means
that
aliasing
components
are
onlytobe
expected
after
half
of
the
sampling frequency has been reached ie. initially after48kHzor44.1 kHz.Byemploying 8 x over-
sampling
in
the
digital filter
these
limits
are
displaced even
further
upwards.
THE
ANALOGUE
OUTPUTS
The
CinchorXLR
analogue
outputsofthe
CD2
possess
two
discretely
constructed
power
amplifiers.
Their
great abilitytoprovide a
current
supply coupled with
their
low
output
resistance
ensures
precise transmiss-
sion of
the
musical signalstothe
pre
amplifier.The phase positionofthe
output
signal can be
rotated
through
180 degrees
via
the
remote
control.
