Serial copy management system (SCMS)

This unit utilizes the serial copy management system that
permits digital-to-digital recording for one generation. You
can record CD sound or other digital formats through a
digital-to-digital connection. (See page 54.)

Three sampling frequencies

Recording/playback can be done with three sampling
frequencies (48 kHz, 44.1 kHz and 32 kHz).

48 kHz: For analog and digital input signals in a standard
mode. 44.1 kHz: For compact disc and pre-recorded DAT tape.

32 kHz: For analog input signals in a long-play mode.

Long play mode

This unit can operate in a long-play mode. Analog input
signals can be recorded or playback for up to four
consecutive hours when the DT-120 DAT cassette tape is used.
The sampling frequency will be

32	kHz in the long-play mode.

Visible cassette loading

You can view the tape operation through the lid of the
cassette compartment. Due to a revolutionary new transport
mechanism, cassette loading time has been significantly reduced.

Excellent sound quality 1-bit A/D converter

For the A/D converter section which converts analog input
signals to digital signals, the unit employs a 1-bit A/D
converter which theoretically generates no zero-cross
distortion for a clear, elegant sound quality.

Pulse D/A converter

Superior playback performance is achieved with a pulse D/A
Rich variety of subcode information

This unit can record subcode information such as Start IDs,
program numbers, Skip IDs, and absolute time data, enabling
you to quickly loçate tunes and display the playback time in
the same manner as when playing compact discs.

Post edit recording of sub codes

You can record or rewrite the following sub codes after the
audio signal recording has been completed.

Start ID: Signifies the beginning of a selection.

Program number: Gives a number to the selection.

Skip ID: Signifies the beginning of a portion to be skipped.

End ID: Signifies the end position of recording/playback.

Since sub codes are written on the tape separately from
audio signals, the audio signals are not affected.
