the waveform. But it does not mean an
"anesthesia" to the ear, to avoid perceiving the
distortions due to deficiencies in the quality of the
electronic circuits of the processors.
Considering that to obtain an excellent
processing is necessary, at the moment, to use
between 7 and 10 stages of processors, the
distortion of each stage must be smaller than
0.01%. Greater distortion values, will lead
inexorably to a degradation of the sound quality.
You must remember that has been
demonstrated (Journal of AES, Vol. 29,4,p.243),
that is possible to measure distortions of 0.05%
through a common loudspeaker (distortion
bigger than 3%). This demonstrates that one
distortion do not mask another one. A practical
rule is, then:
ALL DISTORTION INTRODUCED IN THE AUDIO CHAIN OF
THE TRANSMITTER, THAT EXCEEDS 0.05%, COULD BE
LISTENED BY THE AUDIENCE, EVEN THROUGH
RECEIVERS THAT HAVE VALUES OF DISTORSION 50
TIMES GREATER.
This, of course, is not a novelty for the conscious
audio engineers around the World. Therefore, the
line of SOLIDYNE processors has distortion
values smaller than 0,02%.
Friendly interface
562dsp has many of its automatically fit functions,
under control of the program of audio. But there
are essential controls for "ing personalize ng
personalize” the sound of its radius, that are fit by
the user.
The unit has several programs fit in laboratory for
an optimal performance with different types from
sonorous material. These programs allow you to
be on the air in immediate form.
Soon, you can copy the program chosen to a user
memory, and modify the adjustments to customize
the sound.
When finalizing the adjustment, assigns a
password to the equipment to maintain the
configuration unalterable. Only the engineer who
has the password can alter the sound of the radio.
