High performance 192KHz DA-converter [ MY-D3000], Direct sales price : 315,000 yen
[ Characteristics ]
-
It is a DA converter corresponding to the digital format to 192KHz/24bit.
The circuitry to master the chip of the sigma form thoroughly was pursued in accordance with this.
-
It is use with a DAC chip "AK4399" made in Japan, by the left-right independence monaural composition.
-
The capacitor whose ESR is very low is adopted in the capacitor for the bypass Power-line.
-
Multiple layer circuit boards are adopted in the printed circuit board. The impedance of the GND pattern is being made very Low. A very expensive resolution Noh play is realized by this.
-
The circuit which turned off jitter was embedded. VCXO was combined with the FIFO memory.
It adopts "the multi-level PLL control form" which is characteristic of the PLL control, and it is held to jitter of the low frequency which is a fault of general PLL, and low tone regeneration with weightiness is realized.
-
AD797 to be proud of the top-ranking performance for the stereo system is adopted in the OP amplifier.
An exclusive phase compensation circuit is constructed, and the distortion rate of the high stage is improved by making use of a distortion cancellation terminal more to enhance stability to the capacitive load.
It is the special circuit which it makes use of the performance of AD797 for fully.
