Commentary
Stereo cassette deck with ATCS and anti-vibration mechanism.
A tape bus stabilizer is used to mount the cassette half.
In this system, in addition to the conventional plate spring system, a unique clamper using a compression coil spring and special elastic rubber are used at the tip of the clamper. When the holder is closed, the compression coil spring and special elastic rubber attached to the clamper press down on the cassette half from both left and right sides and fix it firmly. This absorbs vibration of the half and stabilizes tape running and reduces modulation noise.
ATCS (automatic tape calibration system) is adopted in order to use the tape in the best condition.
In ATCS, the calibration of the level (recording sensitivity) and bias of each tape is automatically set by the microcomputer, so that Dolby malfunction due to variation in tape performance can be prevented, and any tape can be used in the best condition.
Logical flow construction is used for internal construction to minimize the signal path.
The KX-5010 uses an extension shaft to position the REC volume near the input terminal to minimize the signal path and prevent degradation of sound quality due to signal line impedance. It also uses an extremely high-quality mini-detent volume to prevent degradation of sound quality due to volume brush resistors.
In addition, rubber couplings are used for the joints of the extension shaft and the volume shaft to prevent vibration from the panel surface from being transmitted to the volume.
The power supply section consists of a 4-winding 2-tap power transformer and 8 stabilizing power supplies. By completely separating the power supply to the read / write amplifier from the power supply for each mechanism drive, the influence of the mechanical drive system power supply to the signal system is prevented.
With this earth separation, a stabilized power supply drives the recording and playback amplifier with low output impedance to achieve high sound quality.
