DAT Machine Sony A7 mint condition, only used a few times. Smoke free home all of its life.
Super clean A7 DAT Recorder, very little use from a smoke free studio.
Here are the specs:
Serial copy management system
This unit utilizes the serial copy management system that permits digital-to-digital recording 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.
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.
