Pioneer T-N901

Commentary

Compact Component Fill Series cassette deck.

It is equipped with Pioneer's original 20-bit digital processing system.
In this circuit, music signals recorded as analog signals are digitized, and signal processing such as high-frequency correction and noise removal, which is directly related to sound quality, is performed by digital processing. In digital NR, music signals are divided into multiple bands by a digital filter, and only noise components are removed to achieve an S/N ratio comparable to that of CD.

The digital FLEX circuit automatically adjusts the high frequencies of old cassette tapes.

The DAC employs a switched-capacitor filter that attenuates out-of-band noise to achieve signal conversion without the effect of jitter.

It is equipped with Legato link conversion.
In this function, the original signal before recording is assumed based on the recorded signal, and the competition music playback is realized by the sound source.

Equipped with a recording level adjustment volume that adjusts the volume of the source.

Equipped with A. S.E.S. function for automatic editing between CDs, MDs and cassette tapes.

A Dolby B/C is installed as a noise reduction system.
