New technology reflected in sound quality. Technical features of the PD-T09. Equipped with legato link conversion that breaks the playback limit of 20kHz. Due to its format, the CD limits the frequency that can be recorded on a disc to 20kHz. However, sounds from nature and musical instruments contain components above 20kHz. Strictly speaking, the original signal waveform itself is not recorded on a CD. Therefore, Pioneer has developed a new Legato Link Conversion that uses digital signal processing to estimate the original signal before recording based on the signal recorded on the CD, and makes it possible to reproduce frequencies above 20kHz according to the 1/f decay characteristic. This is installed in the PD-T09. With more natural sound quality, it opens up new possibilities for CDs. Legato Link Conversion connects the music signal data recorded on the CD every 22.7 µsec with a smooth function curve that is suitable for reproducing the frequency components of natural sounds and musical instruments. This has made it possible to obtain a waveform transmission that is extremely natural and close to the original music signal, without any unnecessary ringing (excessive waveform disturbance). At the same time, this also reproduces ultra-high frequency components above 20 kHz, making it possible to reproduce extremely natural sound quality to the ear.
Equipped with Pioneer's original high-speed pulse flow D/A converter. D/A converters are extremely important components, as their conversion accuracy determines sound quality. Pioneer has advocated the idea of high oversampling and low-order noise shaping in 1-bit D/A converters. The High-Speed Pulse Flow D/A Converter is an original development that further evolves this idea. The 1-bit method expresses the resolution in the amplitude axis direction as two values, 0 and 1, in the time axis direction, and performs high-precision D/A conversion by applying bit compression and further using noise shaping technology. However, re-quantization noise occurs during bit compression, which can cause noise. The noise shaper pushes the requantization noise that is distributed throughout the entire range out of the audible range. However, Pioneer believes that the presence of noise, even outside the audible range, is undesirable in terms of sound quality, and has therefore devised a unique innovation in the noise shaper. In the high-speed pulse flow D/A converter, the noise shaper operates at an extremely high oversampling frequency of 384fs, enabling finer sampling and significantly reducing the noise floor caused by requantization.
Equipped with three independent transformers for digital, analog and DAC. Powerful power supply. The power supply section is the energy source that operates all circuits. In addition to providing a stable power supply, the PD-T09 has also thoroughly eliminated mutual interference. Firstly, the power transformer is equipped with three independent transformers, one each for the digital & servo, analog, and D/A converter. Furthermore, the power supply circuit uses a 6-part 15 regulator. The secondary sides of the three power transformers are separated into six parts: digital & servo, servo drive, D/A converter, and audio +, -, and FL, eliminating mutual interference. In addition, a newly developed discrete power supply is used for the audio circuit. A discrete power supply is also used for the digital & servo.
