Serial copy
management system
This unit utilizes the serial copy management system that permits
digital-to-digital recording tor one generation. You can record CD sound
or other digital formats through a digital-to-digital connection.
Date Function Automatically Stores
The Recording Date And Time
The year, month, day, day of the week, hour, minute and second are
automatically memorized in the subcode area during recording, so that
during playback you can display this data to check when the tape was
recorded. This function is especially convenient when recording live
performances, etc.
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 1-bit D/A converter.
Digital Fade In and Out
Professional sounding fade-in/fade-out of either digital or analog
signals can be accomplished by use of the FADER button.
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
locate 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.
