2. The Design Concept
Thank you for purchasing this fine audio
equipment. First of all we will give you a
small introduction to the ideas behind the
EMP-1
Technically, a CD (or a DVD) is a simple con-
struction, built up with a lot of digital infor-
mation, represented by only two states - zero
or one. The main work for the first section of
the EMP-1 is to read this information. The
EMP-1 have a buffer that reads from the CD
with a higher speed than necessary. If there is
some inconsistent information the system has
time to read it again, and correct the missing
data. With this technique errors introduced
by the CD mechanics are removed. As long as
the first stage of the process has a perfect copy
of the information on the CD there is a basis
for the next stage.
The next stage is to sample rate the informa-
tion. This process removes possible jitter and
also makes sure that all parts of the DAC get
the correct information, at correct time.
The last step is to convert the digital signal
into an analog signal. This is done in two
stages. First the PCM signal is up sampled
to 192kHz. This signal is then up sampled
again to 312 kHz if selected (Factory setting
is 192kHz). After this the High Qualities DAC
converted the digital information to an analog
signal.
After this process the signal passes trough the
fully balanced, symmetrical, state-of-the-art
internal analog output stage - ready to be con-
nected to your system.
