Commentary
Equipped with a 32 fs Fine D. R. I. V. E. system, this CD player achieves a signal-to-noise ratio of 120 db.
It is equipped with a 32 fs Fine D. R. I. V. E. system that combines the D. R. I. V. E. system with a 32 fs 22 bit high resolution digital filter.
As a result, we obtained a resolution equivalent to 22 bits at a sampling frequency of 1.4 MHz, and succeeded in generating digital data closer to the original analog waveform, achieving a high SN ratio of 120 dB.
A structure that suppresses disk resonance is adopted by a sound pressure shielding structure.
The mechanism is covered with an aluminum case. The aluminum top mechanism is covered with a printed circuit board, and the case is covered on the printed circuit board. This multi-layer structure suppresses vibration and reduces unnecessary servo current.
Contains coaxial and optical digital output jacks.
Also, gold plated terminals are used for terminals.
It is equipped with editing functions such as CD peak search which can set recording level with less distortion, edit function and auto space.
You can adjust the output level and headphone output level.
Equipped with an emphasis indicator.
