TIPS:
To
produce
the
connections
between
individual units
of
your
hi
fi
equipment and
the
CD2
only use
high
qua-
lity digital cabling
not
exceeding 50 cm
in
length. Near-by placed radios
or
televisions can
otherwise
suffer
reception interference.
If
optical cable
is
used as adigital connection
the
length of
the
cable
is
not
critical.

THE
CONCEPT
OF
THE
EVOLUTION
CD2
The
C02
has been optimized
to
a
sure
and extremely jitter free read
out
of
the
digital information
where-
by
the
quantity
of
information
is
unmistakably defined
by
the
CD
format
16
Bitl44.1 kHz
at
the
converter
input.Additional information
in
the
sense
of
ahigher resolution
or
an
extended
frequency range
is
not
achie-
vable. Most
of
the
currently used digitallanalogue (D/A)
converters
are
not
able
to
completely
convert
the
information offered on
the
CD
to
analogue signals for
the
following reasons.
A n
in
built problem with systems when reconverting digital information
is
the
so-called quantization noise.
This results from slight inaccuracies displayed
by
the
discrete existing values
in
comparison
to
the
original
analogue signal.
With
the
CD
format
these
inaccuracies are defined
by
the
16
Bit
word
breadth,
in
other
words
that
during
the
production
of
the
CD
a
pendant
with amaximum resolution
of
65,536 stages
is
atta-
ched
to
the
analogue signal.
If
an analogue signal lies between
these
stages aprinciple
error
occurs
during
recording which limits
the
achievable tonal quality.
The
recording
is
therefore
produced with afar
greater
resolution than can actually be
stored
on
the
CD
in
an
attempt
to
minimize
the
error.
The
remaining inaccuracies are randomly distributed and
become
apparent during re-conversion
as
an
even-
ly
distributed noise
over
the
useful frequency band.This noise limits
the
dynamic characteristics approaching
the
lower ranges and ieads
to
concealment of
the
fine information held on
the
CD.
If
the
digital signal
is
upsampled
to
ahigher frequency
prior
to
re-conversion
the
quantization noise
is
distributed
over
a
greater
frequency spectrum. However because
the
noise energy remains
constant
the
greater
noise band width leads
to
alower noise level. Alarge
part
of
the
noise
is
now situated outside
the
relative audio frequency band
and can be filtered
out
relatively easily.This
does
not
mean
that
new information
is
gained
however
that
part
of
the
information
that
was previously covered
by
the
noise becomes audible.
For this reason
the
digital signal of
the
C02
is
upsampled
to
24 Bitl96 kHz
prior
to
the
DIA conversion.
The
enlargement
of
the
word
breadth
to
24 Bit leads
to
aclear reduction
of
the
quantization noise
of
the
DIA
converter.
At
the
end
of
the
frequency range
the
low frequency signals must be filtered
to
separate
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 afrequency
of
22
kHz with
standard
CD
format.This makes
the
employment
of
steep sloop analogue filters
of
a
high
order
necessary
which lead
to
an
increase
of
the
phase- and amplitude distortions.
In
comparison upsampling
to
96 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
minimization
of
jitter. Deviation
in
the
pulse
rate
of
the
digital signal
is
known
as
jitter.These deviations, which are for
the
most
part
caused
by
the drive, results
in
the
offered infor-
mation being processed
at
the
wrong
moment
of time.This causes distortion and noise
in
the
analogue range
that
in
their
turn are responsible for faded and slightly roughened tonal characteristics.
There
are many ways of ensuring
that
the
offered information
is
processed
in
its
exact
chronological
sequence.
AVM
has decided
to
proceed
along aradical and uncompromising path.
All
of
the
clock pulse
frequencies
that
are necessary for signal processing are
generated
in
aspecial module
that
is
not
timed
by
a
normal quartz crystal but instead
by
a
high
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 information
is
independent of the
44.1
kHz clock pulse. Intermediate
storage
in
abuffer 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
aminimum. 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 alot 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 aCO 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 aflatter
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.
22
Besides this
the
digital filter increases
the
sampling frequency
by
afactor
of
8(oversampling) through
extre-
mely fast calculation of intermediate values,
thereby
permitting
the
analogue filter at
the
converter
output
to
be
laid
out
in
as
considerate a
manner
as
possible with regard
to
phase and amplitude.
All
necessary pulse frequencies are
produced
by
amutual,
extremely
precise pulse generator.
The
audio digital information
is
available
in
CD
standard
format
(16
Bit!
44.1 kHz)
on
each
of
the
three
dig-
ital
outputs.
THE
DIGITAl/ANALOGUE
(D/A)
CONVERTER
The
raw data from
the
digital filters
is
passed discretely through
separate
channels
to
the
D/A
converters.
We
install only pre-selected Burr-Brown
PCM
1704 converters.This
high
precision parallel con-
verter
is
considered
to
be
the
best
product
available
on
the
market. Strict selection
procedures
and careful
laser trimming of
the
converter
by
the
manufacturer
ensures
constant
high
tonal quality
of
the
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 filtering
to
be very important.
The
way
in
which
filters
work
with phase and amplitude
of
the
signals can have serious effects
on
the
tonal quality
of
aD/A
converter.
We
have
created
afilter
that
causes no ampiitude
or
phase
errors
within
the
audio frequency
range.This was possible because upsampling means
that
aliasing
components
are
only
to
be
expected
after
half
of
the
sampling frequency has been reached ie. initially after
48
kHz
or
44.1 kHz.
By
employing 8 x over-
sampling
in
the
digital filter
these
limits
are
displaced even
further
upwards.
THE
ANALOGUE
OUTPUTS
The
Cinch
or
XLR
analogue
outputs
of
the
CD2
possess
two
discretely
constructed
power
amplifiers.
Their
great ability
to
provide a
current
supply coupled with
their
low
output
resistance
ensures
precise transmiss-
sion of
the
musical signals
to
the
pre
amplifier.The phase position
of
the
output
signal can be
rotated
through
180 degrees
via
the
remote
control.

PLACEMENT
OF
THE
UNIT
I
COOLING
Place
the
CD2
unit so
that
the
CD
tray (8) has
at
least
15
cm clearance
to
the
front.This
will
ensure
that
the
tray can
open
and close
without
hindrance.
The
CD2
produces
little
warmth
during use. Installation
in
arack
therefore
causes no problems.
When
pla-
cing
in
acabinet please
ensure
that
free air circulation
is
possible.
We
recommend
that
the
unit
is
placed
where
it
is
protected
from
direct
sunlight.This
ensures
that
the
display
is
easily legible and
the
effectiveness
of
the
remote
control
unit
is
not
affected
by
extreme
sunlight.
The
CD2
should
of
course
not
be placed
in
close proximity
to
heating appliances
or
in
adamp environment.
If
you
are
placing
other
units above
or
below
the
CD
player
then
please
ensure
that
Icm distance
is
main-
tained
between
the
units and
your
CD2.
If
necessary place additional spacers
beneath
the
unit's
feet
to
provide
the
necessary distance.

to
interference
of
other
musical
sources
because
of
the
resultant

TIP:We
recommend
that
the
connections
should be
made
with symmetrical cable (AES/EBU)
or
75
Ohm
coaxial cable.
In
our
experience
these
provide
the
best
audio results.
Use
only cables with alength
not
exceeding 50 cm. Longer cables could lead
to
reception
interference
of
radio
or
television
equipment
in
close proximity.
Under
no
circumstances should coaxial
or
optical cable be sharply
bent
or
kin
ked.This could
cause
audible
interference
(interference noises)
or
completely
prevent
passage
