An 8-PCM-channel with 20-bit/sample data slot is available at the sampling frequencies of 48, 44.1, and 32 kHz. High-quality recording and editing functions are provided for semiprofessional and superior amateur use. The newly developed thin-film magnetic heads and the high-density recording technology enable more than 20 minutes' recording on 8-mm tape loaded in a compact-size cassette. The features and signal processing technology of this digital audio recorder are described.<
