MAGIC CD
INTRODUCTION
CD intended to accelerate and intensify the break-in of speakers and certain electronic devices.
Jean Marie Reynaud first developed these signals for his own needs, in order to achieve more quickly
stabilization of the characteristics of the loudspeaker equipment (the loudspeakers).
Jean Marie Reynaud first developed these signals for his own needs, in order to achieve more quickly
stabilization of the characteristics of the loudspeaker equipment (the loudspeakers).
Subsequently, he offered this recording to his network of resellers, giving them the means of a faster
and more thorough break-in of the speakers offered for listening, and finally decided to make it accessible
to individuals, for their own needs.

DESCRIPTION
Please note that the use of this lapping disc requires special precautions to avoid damaging the equipment.
The use of this disc is done under the exclusive responsibility of the people who use it.
This CD operates a powerful shortening of the equipment break-in time, which it will be advisable for the
JMR speakers to continue with musical messages played continuously.
This CD operates a powerful shortening of the equipment break-in time, which it will be advisable for the
JMR speakers to continue with musical messages played continuously.
A successful break-in of JMR speakers is carried out by the 2 joint methods: music and break-in CD.
This CD has been produced with care, it is intended to very significantly reduce the break-in time of the elements
of a high fidelity system (approximately 10 times less time than with a musical program).
It does not include any musical track. It should therefore be considered as a purely technical instrument and will only
be used with high quality equipment.

On this disc is recorded a random noise signal in narrow band allowing to simulate, at a reasonable noise level,
the extreme conditions of use of the components of the chain and in particular, those which concern all its mechanical
parts (CD player and speakers).
It must be used with the most extreme precautions in order to avoid any incident to the various links in the chain (mainly the loudspeakers).

It must be used with the most extreme precautions in order to avoid any incident to the various links in the chain (mainly the loudspeakers).
The narrow band of random noise recorded on this CD comes from a signal obtained by filtering the signal from
a white noise generator fed by a series of modulators and filters.
The resulting signal is 1.2 MHz of narrow band of random noise with an adjustable bandwidth of 10 Hz, 31.6 Hz,
100 Hz, 316 Hz and 1000 Hz.
The center frequency of each sample recorded on this disk was chosen from a band between 2 Hz and 200 KHz.

PROCEDURE FOR USING THE DISC:

Very gradually increase the volume while looking at the cones of your bass speakers,

Each new use of this disc, even partial, will involve the same adjustment procedure.
NOTE: To run in the loudspeakers, you can connect the two loudspeakers in phase opposition
and position them face to face quite close to each other (approximately 30 cm), the noise
generated will be reduced (acoustic short-circuit) the break-in is carried out just as efficiently.
