Digital Audio Tape

DAT (Digital Audio Tape) is a new recording system which digitalizes the audio signal and records it on a DAT cassette tape.

DAT records the audio signal by converting the analog sound into a digital signal. This converting system is called the PCM (Pulse Code Modulation), and its accurate processing of the audio signal allows recording/playback with lower wow and flutter, wider dynamic range, lower distortion rate, and superb signal-to-noise ratio. In addition, various control codes calls sub codes can be written on the DAT cassette separately from the audio signal. They are written for a variety of convenient playback/tape editing operations, and except for the absolute time, can be rewritten after audio signal recording has been completed.

Precautions

Features

On safety

• Operate the unit only on 120 V AC, 60 Hz.

• The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off.

• Should any solid object or liquid fall into the cabinet, unplug the unit and have it checked by qualified personnel before operating it any further.

• Unplug the unit from the wall outlet if it is not to be used for an extended period of time. To disconnect the cord, pull it out by grasping the plug. Never pull the cord itself.

• AC power cord must be changed only at the qualified service shop.

Operation

Before making program source connections, be sure to unplug the unit.

Installation

Do not install the unit in a location near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.

Moisture Condensation

If the unit is brought directly from a cold to a warm location, moisture may condense inside the unit. In this condition, the tape may adhere to the head drum and be damaged, or the unit may not operate correctly. Always remove the cassette when the unit will not be used.

If moisture is present...

• Function controls will not operate.

• All operations will stop.

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 converter.

When the CAUTION indicator lights and the unit will not operate

Leave the unit turned on for about an hour.

NOTE

When closing the cassette compartment, do not push the cassette lid forcibly by hand, but perform with the 0OPEN/CLOSE button.

For the customers in the U.S.A.

For detailed safety precautions, see the “IMPORTANT SAFEGUARDS” leaflet.

If you have any question or problem concerning your unit, please consult your nearest Sony dealer.

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.

Blank Section and Sound Muted Portion

With conventional analog audio tapes, the tape portion on which no recording ever has been made and the portion on which a recording has been made but the sound is muted are treated the same, since no sound can be heard from these portions. However, with DAT cassette, you should know that the two kinds of “no sound” portions must definitely be distinguished one from the other.

Important

When recording, be certain that no blank section is left on the tape. If blank sections remain on the tape, search operations using the AMS buttons, for example, may take quite a long time or the absolute time is not written correctly.

Difference between the blank section and sound-muted portion

When you record, a track format is constructed on the recorded area, even if the sound is muted during recording. On the blank section, since no recording is applied, there is no track format.

The absolute time codes correctly written on the tape can be used in various convenient ways during playback.

Recording absolute time codes

When you record, the absolute time codes are also written automatically from the beginning of the tape. Once the absolute time codes are recorded, it cannot be re-written. With the absolute time, you can check the elapsed time from the beginning of the tape. Note, however, that the absolute time codes are not written if you start recording from the middle of blank section. No blank sections should be left on the tape when recording.

Tips for recording:

• To insert silence between selections, use the record muting function (page 25). Do not advance the tape with the ¡ or 3 button.

• To start recording from the middle of the tape, use the end search function (page

26) to locate the beginning of the blank section. This will avoid leaving a blank section.

If a blank section is left on the tape

If you start recording from the middle of a blank section, the absolute time codes are not recorded, since the DAT deck can no longer count the absolute time from the beginning of the tape.

Using sound muted portion

If you intend to dub the DAT cassette onto an analog cassette tape, we recommend that you insert sound muted portions between selections on the DAT cassette. This will ensure that the AMS function of the analog cassette deck works correctly for the recorded tape.

Note

With DAT deck, the AMS function is realized by using the start ID code. (Page

29.)

Caution

To place a space on a DAT cassette, you must not advance the tape with the ¡ or 3 button. If a space is created this way, no absolute time code will be recorded on the succeeding area, and you cannot check the elapsed time of the tape.

To create a sound muted portion of more than 4 seconds

Keep the •REC MUTE button pressed for as long as you want to make a recorded portion with no signals. After about 4 seconds, the REC indicator flashes rapidly. When you release the •REC MUTE button, the deck enters the record-pause mode. The interval between selections is indicated at the MARGIN display.

To create a sound muted portion of less than 4 seconds

Sub Codes

In addition to the ordinary audio signals, various control codes called sub codes can be recorded on the DAT cassette tapes to ease recording and reproducing operation. Å A)The sub codes are recorded. B)Audio signals are recorded.

A desired selection can be called up or time information can be displayed using the sub codes, for example. The sub codes such as start ID, program number, skip ID, end ID and absolute time are available on this unit.

• Sub codes are written on the tape separately from the audio signals, so the audio signals are not affected.

• Sub codes, except the absolute time, can be rewritten after the audio signal recording has been completed. The recorded audio signals are not affected by the rewritten sub codes.

• When you record the tape with sub codes written onto a new tape via digitalto-digital connection, the sub codes to be written on the new tape are following:

Start IDs

Skip IDs

Program Numbers

Maintenance

Cleaning the Cabinet

Clean the cabinet, panels and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive and, scouring powder or solvent such as alcohol or benzine.

Cleaning the Head

Prolonged operation will cause contamination of the head. To make the best possible recording and playback, we recommend cleaning the head periodically, using the DT-10CL cleaning cassette (not supplied).

How to use the cleaning cassette

1 Insert the cleaning cassette as you insert

a normal DAT cassette.

2 Press 3. Press 7 after about 10

seconds.

3 Remove the cleaning cassette without

rewinding it.

4 Proceed with recording and playback

with a normal DAT cassette and check the sound quality.

Notes on the cleaning cassette

• The cleaning cassette cannot be used for recording and playback.

• Do not clean the head with the cleaning cassette more than five times over a short period. Cleaning the head continuously for a too long period of time may cause wear to the head.

• Do not rewind the cleaning cassette each time you use it. When the cleaning cassette tape is taken up completely, rewind it to the beginning and re-use it. The cleaning cassette can be used two hundred times, with 10 seconds of cleaning each time.
