Commentary
CD player with 32 fs Fine D. R. I. V. E.
The 32 fs Fine D. R. I. V. E. system, which combines the 32 fs 22-bit digital filter with the D. R. I. V. E., is an improved version of the D. R. I. V. E. system originally developed by Kenwood.
The resolution equivalent to 22 bits has been obtained at a sampling frequency of 32 fs 1.4 mhz, four times higher than conventional ones, and a high SN ratio of 120 db has been achieved, exceeding the conventional limit.
In addition, by eliminating the need for a high-order low-pass filter, group delay characteristics within the audible band are improved and localization is improved.
Equipped with digital inputs for the total Route 3 of two coaxial systems and one optical system, it can also be used as a stand-alone D/A converter.
It employs an aluminum top mechanism that is covered with an aluminum case. In addition, the mechanism is covered with a printed circuit board and covered with a case on top. This structure employs a three layered sound pressure shielding structure.
This suppresses various disturbances caused by sound pressure and reduces unnecessary servo current.
Center mechanism configuration of double vibration control structure is adopted.
In addition, a large clamper and pick-up vibration suppression structure are adopted.
Equipped with an edit function convenient for dubbing.
You can do most of the operation with the remote control attached to KAF-5002 and KAF-7002, and there was a dedicated remote control sold separately when you use the CD player by itself.
