The heritage of the CD range
CD10 is the first in a range of CD players which are widely recognized as being best sellers in their
category due to their excellent sound quality and first class reliability. At MICROMEGA we set our heart on
developing a CD player whose performances would be exceptional while maintaining unbeatable value for
money.

The chassis
Made entirely out of metal, the frame’s role is to provide a stable and rigid base for the CD mechanism. It
also protects the CD’s electronic circuits against external electromagnetic disturbances and high
frequency exposure, which are very common in today’s environment. The aluminum front panel adds a
special touch to all of the models of this range, providing an impression of elegant soberness, where
minimalism and user-friendliness combine harmoniously. The blue 10 character dot matrix display, driven
by MICROMEGA software, displays all necessary information in real time. The aluminum anodized top
cover, which comes in either black or silver, matches the front panel perfectly. The brushed effect of the
front panel gives the product an unrivalled distinctive touch.

The power supply
Like all the players, CD10 depends on the user’s mains source for its power supply. Unfortunately this
source is increasingly subject to interference, especially since the arrival of switching mode power
supplies used by computers as well as by numerous other consumer electronics goods, for example TV
sets, DVD players, video tape recorders, and satellite devices among others. All these power supplies,
even if according to CE standard, they are supposed to prevent any input or output disturbance, emit
towards the mains high frequency signals likely to disturb the CD’s musical reproduction. The effect is
more significant the more powerful the device is. If that seems paradoxical, it should be kept in mind that
the maximum output signal of a CD player is 2V RMS; therefore the weakest signal that a CD player must
be capable of reproducing is about 30 micro-volts. That gives a good idea of the scale of what we are
talking about. The CD10’s transformer is an R-Core type. These very specific models have very
interesting characteristics from the point of view of mains interference filtering. Contrary to toroidal
transformers, which have a very broad bandwidth, R-Core transformers, due to the way there are made,
have a very narrow bandwidth. This makes them the ideal choice when the current requirement is
moderate. CD10 is equipped with a linear power supply made up of several distinct sections in order to
avoid the problems of cross talk from the power supply, in particular between the digital and analog
sections. The digital power supply provides the necessary current to the drive mechanism, the feedback
circuits and to all of the user interface section. In addition, linear regulators with high power supply
rejection guarantee a perfectly noise-free power supply for all of the digital elements. As for the analog
section, it requires a very different technique. After rectification and filtering, the regulation of the analog
power supply is carried out by a very sophisticated circuit, which calls upon high impedance, low noise
power, combined with tracking regulators. The rejection level of this power supply is higher than 100dB
and this from 20Hz to 20 kHz. The digital section of the digital-analog converter features a constant power
source and a shunt type, very low noise regulator.
