The material selected carefully and the compact disk
player which pursued musicality by the extravagant circuit design.
4ch independent digital analog converter which carried out the full separation
of the four channels of a right-and-left channel and positive negative phase at
the digital analog converter, and constituted the circuitry is adopted. This has
realized the full balance transmit and the ambiguity related to a phase is
eliminated. Moreover, the cross interferencee is prevented because after an
analog translation adopts a 4ch independent circuitry.
correction and EFM decoder which were newly developed making full use of the
technology of NEC, and the microcomputer for a control are carried, and the accuracy and robustness of the signal processing are improved.
phase gap and distortion are reduced by applying a polish to original
network-description filter also about a digital filter.
A total of 2 clock signal for serial datas and four optical cables of one
latch pulse each and the object for control signals have realized the optical
transmission of a digital signal by five photocouplers.
This intercepted the electronic join of a
digital circuit and an analog circuit, and mixing of the digital noise is
The low-distortion analog attenuator which can control even
0-29dB at a 1dB step is carried.
It has hi-reliability, a high-quality sound
electrical resistor, and composition by sealing scheme relay of a gilding
The steel plate of 3.2mm thickness is adopted as a
sole plate, and the fine oscillation from an internal-rotation system is
Furthermore, it has a structure strong also against a long
oscillation and visitor oscillation of a periodicity by sticking the sintered
alloy foot which was excellent in the vibration-proof dynamic behavior with high
rigidity to a floor surface.
Moreover, the steel plate of 1.6mm thickness
was used for the chassis itself, and the aluminum board of 5mm thickness is
adopted as a side plate, a top plate, and the front.
A balance input
terminal and two kinds of imbalanced output-terminals of a right phase and
negative phase are carried in the output-terminal.
The full function wireless remote commander is carried.
