Loading the individual integral calculus type modulation circuit "VL Digital" in order from to operate the same system ideally. The error which originates in spike noise was removed, you say that accurate pulse duration modulation was actualized. Furthermore, the inverted Darlington circuit that is loaded it cancels amplifying element specific nonlinear characteristic in the front step of VL Digital.

Adopting the discrete driver to the driver step. You say that acceleration of several times was actualized in comparison with the driver circuit by IC tip/chip.

In power source section toroidal trance of bulk 2, the one for + side - on one for side arrangement. Reduction of dynamic source impedance is assured, you say that the power source supply whose stability is high is made possible to the digital amplifier circuit. In addition, adopting the copperplate for the gland line which ties the small ringing circuit with the electrolytic condenser. Both the signal line and the gland line adopting the copper bus plate for also route to immediately before the speaker terminal from the output step. You say that the timbre where the core is thick was actualized.

Adopting the 1.6mm thick steel sheet to the frame. To administer the gold-plating to the speaker terminal, the cable to of core diameter 4mm connected possibility. It corresponds to also the connection of the banana plug. As for input terminal analog 7 systems, as for output terminal analog 4 systematic equipment. Also MAIN IN input has, it is possible also to utilize only the power amplifier section. As for external size 275×328×103mm (width × depth × height), as for weight 7.5kg.

* CD player


C-733, same as MD-133 of the MD deck, loading the individual analog corrugated formation technical VLSC circuit. Influence of digital noise is decreased, you say that potential of the source can be pulled out to the maximum. It supports the playback of music CD and CD-R, but the playback function of MP3/WMA does not have.

Adopting 192kHz/24bit DAC of シーラス logic make. Furthermore, the quartz oscillator loading "the super precision which had the precision of ±1.5ppm at normal temperature as a clock circuit, clock" circuit. Fluctuation with the time base is removed, improvement of descriptive power is assured.

The downstream coil of power transformer, audio type + side/- side, the for display tube, by the fact that it becomes independent for mechanic drive and with the one for micro-computer, individually, adopting the design where the noise which occurs from each circuit does not exert influence on the audio circuit to the power circuit. The voltage stabilizer which becomes independent you used even in each circuit which forms the audio circuit multiple regulator system is adopted, you say that mutual interference of the circuit is prevented.

As for playback frequency characteristic 5Hz - 20kHz. As for signal-noise ratio 105dB. As for dynamic range 96dB. As an output terminal, optical digital 2 systems, analog sound 1 system is had.
