Commentary
A DAT deck that achieves both high performance and affordability.
A 2D. D. + reel motor mechanism is adopted, and independent direct drive motors are used for the capstan and the head drum rotation, which are key points of the tape drive mechanism, respectively, and a special motor is used for the reel.
The A/D converter is equipped with a pulse A/D converter with a built-in 1-bit modulator, and achieves a theoretical S / N ratio of 119 dB by performing high-speed, high-precision operations with 64 x oversampling and 5th order noise shaping.
In addition, by separating it from the decimation filter that performs the digital operation to return the sampling rate and making it independent, the influence of noise on the modulator that handles analog signals can be reduced.
Equipped with SBM (Super Bit Mapping) digital filter.
SBM achieves significant noise reduction by shifting quantization noise that is uniformly distributed within the audible band to higher frequencies that are difficult to hear due to human audibility characteristics, and by recoding low-order 4-bit information that is normally truncated to high-order 16-bit information using the principle of noise shaping.
The SBM digital filter uses the built-in decimation filter to reduce aliasing noise and uses the SBM to convert the 24-bit data output from the decimation filter into 16-bit data almost as it is, enabling high-quality recording.
The D/A converter employs an advanced pulse D/A converter that uses Sony's proprietary high-precision calculation method to achieve higher pulse output density.
By using single-chip ICs with single-channel 4D/A outputs and double-channel 8D/A outputs, and performing complimentary service PLM operation (differential-synthesis of two pulse wave outputs that are complementary to each other), the generation of harmonic distortion is reduced.
The analog input supports recording at a sampling frequency of 48 kHz, 32 kHz (long duration), and 44.1 kHz.
When recording a CD with digital input, the Q-code of inter-song information can be decoded so that an accurate start ID can be automatically written.
It is equipped with subcode editing functions such as start ID, rehearsal function, program number, renumber and absolute time.
In addition to AMS play and AMS search functions, it is equipped with functions such as program number search, repeat one song / all songs, and end search.
SCMS is supported.
Digital peak margin display is available.
An eccentric insulator is used for the insulator.
Uses gold-plated terminal.
Wireless remote control is included.
