Sony DTC-A8 DAT Recorder
The DTC-A8 was introduced in 1995.
The DTC-A8 was a semi-pro machine and included the SBM feature.
Identical to the professional PCM-2600, except the PCM-2600 has balanced XLR connectors and an AES/EBU digital interface.
Uses a 4DD (Direct Drive) motor mechanism.
Has connectors for a foot switch.
A footswitch can be connected to one of two standard jack sockets on the rear of the machine to perform a number of useful functions.
The first socket is labelled Rec/Pause and each press of the footswitch simply toggles the machine between the record-pause mode and actual recording.
The second socket is labelled Mode, and the function of the footswitch is determined by a three-position slide switch on the left of the front panel.
The first mode is a simple play-stop-play function, each press of the footswitch activating the next operation in the cycle.
The second mode includes a review facility when the machine is playing: when you press the footswitch, the tape is wound back about 15 seconds and played again.
The last mode replaces the review function with an AMS search, so that the tape winds back to the previous Start ID and stops. All of these functions are very useful, giving hands-free operation when you're trying to learn a piece of music or rehearsing against a backing tape.
Supplied with a rack mount kit.
High-Reliability 4 D.D. Transport
Transport mechanism is equipped with four direct drive motors for an extremely stable tape path.
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.
Super Bit Mapping (SBM)
The basic theory is that when you record through it's 24-bit analog converters using SBM, the processor filters the 24-bit audio to yield a final product that sounds better than normal 16-bit quality. SBM does that by weaving out the least significant 8-bit information into 16-bit filtered data.
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.
