CD player which carries a current injection circuit and a LEF circuit.
It changes to the conventional operational amplifier and the current
injection circuit original with CEC and the LEF (load effect-free) circuit are
carried. This became completely free from the NFB loop, and it has succeeded in
processing a signal on a one stage. moreover, signal processing formed into full
balance -- high speed -- and -- low -- distorted transmission is realized.
The circuit consists of pure Class-A operation.
In the power-source
part, in order to change the polluted commercial law AC power into a direct
current which was clean and was stabilized, contamination is removed through AC
line filter and the primary side high frequency switching regulator is purifying
the high voltage power supply.
Moreover, the switching regulator and high
frequency insulation transformer by a PWM (pulse width modulation) system have
been arranged independently to secondary low voltages at the servo system and
the audio signal system, respectively, and the mutual intervention is
eliminated.
furthermore, stability of a power source and clean-ization are
performed by boiling both primary and secondary switching regulator outputs, and
letting it pass to two or more steps of line filters.
(In order to pull out
the engine performance of a line filter, it recommends using it, connecting the
grounding terminal of AC cable to a ground)
Two PCM1796 corresponding to
24 bits/192 kHz are adopted as a D/A converter. The advanced segment system
which united and developed the multiple bit system and the delta sigma system
newly was adopted, and the outstanding dynamic characteristic has been acquired.
Moreover, the Filter function preselection capability which can change
"FLAT" which enables a more nearly linear play, and "SOFT" decreased with nature
from 20kHz this side by remote control operation as an option function of a DAC
circuit,The Dither switch which reduces distortion of the signal of a minute
level very much, sigma-FS function in which an exaggerated sampling rate can
be changed by a three-stage, etc. are carried.
Three lines of light, the
same axle, and XLR are carried in the digital output.
Moreover, the analog
output carries two lines, a balanced type and an imbalanced type.
