Recording Operations 3-856-761-11(2) The segments of the peak level meters corresponding to the maximum signal strength remain lit longer than normal. The MARGIN indication shows the margin between maximum signal strength and 0 dB, changing each time a stronger signal. Recording Operations For basic recording operations, see pages 6 and 7. Things You Should Know Before Recording The difference between a blank section and a sound-muted section The deck distinguishes between two kinds of silent sections, which are respectively called a “blank section” or “sound-muted section”. Blank section This is a section on which no signal has ever been recorded. If “EMPHASIS” appears in the display The deck is recording a digital signal with emphasis (in the higher frequencies). The recording will also contain the same emphasis. If the deck is left in recording pause for more than 10 minutes Recording pause will be released automatically, the deck will stop and “SOURCE” will appear in the display. To resume recording, press the REC r button. The deck will change to recording pause. When using a new tape Before you record on a new tape, we recommend that you fast forward the whole tape and then rewind to the beginning to make the tape reel smoothly. Adjusting the Recording Level for Analog Recording Before you start recording an analog source through ANALOG (LINE) IN, set the INPUT switch to ANALOG and adjust the recording level.

a): Recording b): Track Sound-muted section This is a section on which a signal has been recorded but at a level that is not audible.

Sound-muted section Important Make sure no blank sections are created while you are recording. The existence of blank sections within recorded material will make search operations using the PREVIOUS =/NEXT + buttons impossible or destroy the continuity of the absolute time codes. z If you press the REC r button while in a blank section The deck automatically rewinds the tape to the beginning of the blank section and changes to recording pause (except during Timer Recording). Absolute time codes Absolute time codes indicate the elapsed time from the beginning of the tape. These codes are automatically recorded. Note that once recorded, absolute time codes cannot be re-written. For accurate recording of absolute time codes

• If the tape is blank, make sure to start recording from the beginning of the tape.

• Use Record Muting (see page 11) to insert spaces between tracks. Do not advance the tape with the PLAY ( or FF ) button.

• To start recording from the middle of a tape, use End Search (see page 10) to locate the end of the recorded portion. This will prevent the creation of blank sections. PLAY ( PAUSE P MARGIN RESET REC LEVEL

MARGIN indication

Recording Operations 3-856-761-11(2) Set REC MODE to select the recording mode. The following table shows the selectable recording modes and corresponding REC MODE position and sampling frequency for various input signals. If the level exceeds 0 dB The segments under “OVER” light up, and “0.0 dB” flashes in the display. If these segments light steadily, sound distortion may occur. To avoid this, keep the recording level between –12 dB and 0 dB. To reset the margin indication Press MARGIN RESET. The margin indication changes to “- - dB”. 4 Stop playing the program source. 5 To start recording, press PAUSE P or PLAY (, then start playing the program source. Locating the End of the Recorded Portion (End Search) End Search detects a blank section longer than 9 seconds, then automatically rewinds the tape to the end of the recorded portion, then stops. Use End Search to start recording from the end of the recorded portion without creating a blank section on the tape. Setting the Recording Mode You can select either of two recording modes— standard or long—in the following cases.

• When recording an analog input signal with the INPUT switch set to ANALOG

• When recording a digital input signal with a sampling frequency of 32 kHz with the INPUT switch set to OPTICAL or COAXIAL. REC MODE

The deck stops at the beginning of any blank section that is 9 seconds or longer, or fast-forwards to the end of the tape if the tape is blank. z If you press the REC r button while in a blank section The deck automatically rewinds the tape to the beginning of the blank section and changes to recording pause. “BLANK” and “WAIT” appear in the display while the deck is searching for the beginning of the blank section. Notes

• End Search does not operate if you press the FF ) button while in a blank section.

• If the tape is blank, the deck merely fast-forwards to the end of the tape. The recording time in long-play mode (the REC MODE switch set to LONG) is twice as long as standard-play mode.11

Recording Operations 3-856-761-11(2) Inserting a Sound-Muted Section While Recording (Record Muting) Use Record Muting to insert a space of about 4 seconds between tracks. This is recommended if you plan to copy the DAT tape to an analog audio cassette tape since the spaces will allow you to use automatic search functions to locate the beginning of each track. When you start recording from the beginning of a blank tape and want to insert a space before the first track, be sure to create a sound-muted section using Record Muting only. Do not advance the tape with the FF ) or PLAY ( button since this will create a blank section on the tape (see page 9). z The counter in long-play mode The displayed tape running time, absolute time and remaining time on the tape are for standard-play mode. Double the time to obtain the corresponding times for long-play mode. Note Do not change the INPUT or REC MODE setting while recording. This may cause an error in the “PGM TIME” (playing time of the track) display. Using the SBM (Super Bit Mapping) Function You can use the SBM function to record on analog input signal only when the INPUT switch is set to ANALOG and the REC MODE switch to STANDARD (either 48 kHz or 44.1 kHz). For details on the SBM function, see “SBM (Super Bit Mapping) Function” on page 20.

+ 0) L R 1 Press REC MUTE R where you want to insert a space while the deck is recording or in recording pause. The deck creates a sound-muted section as “REC” flashes in the display. After the sound-muted section is completed, “REC” lights up and the deck changes to recording pause. To insert a blank space longer than 4 seconds Hold down the REC MUTE R button as long as you want. When you release the button, the sound-muted section ends and the deck changes to become recording pause. If you keep the button pressed longer than 4 seconds, “REC” will begin to flash more quickly and the time elapsed after pressing the REC MUTE R button is shown in the display. When you release the REC MUTE R button, P in the display stays on and the deck changes to recording pause. 2 Press PAUSE P or PLAY ( to resume recording. The deck starts recording again. Note If you do not create a sound-muted section at the beginning of a tape, you may not be able to move or erase a start ID (see page 14) that is recorded within 2 seconds from the beginning of the tape. Set SBM to ON. “SBM” appears in the display during recording using the SBM function. To turn the SBM function off Set SBM to OFF. SBM

COUNTERRESETREPEATCLEAR

REPEAT Playing all tracks repeatedly Press REPEAT repeatedly while playing a track until “REPEAT” appears in the display. The deck will then play back all tracks until it detects the end of the last track, which may be: — a blank section of 9 seconds or more — the end of the tape When the deck detects either of the above, it rewinds the tape to beginning and plays back all tracks again. The deck repeats this cycle up to 5 times, then automatically stops. To stop playing all tracks repeatedly Press REPEAT repeatedly until “REPEAT” disappears. Note Repeat Play of all tracks is canceled when you take out the cassette. Playing a track repeatedly Press REPEAT repeatedly while playing the track that you want until “REPEAT 1” appears in the display. The deck will then play back the track until its end, which may be: —the next start ID —a blank section of 9 seconds or more —the end of the tape When the deck detects any of the above, it rewinds the tape and starts playing from the start ID of the same track again. The deck repeats this cycle up to 5 times, then automatically stops. To stop playing a track repeatedly Press REPEAT repeatedly until “REPEAT 1” disappears. Note Repeat Play of a single track is canceled when you take out the cassette. If “EMPHASIS” appears in the display The deck is playing an audio signal recorded with emphasis (in the higher frequencies). The deck, however, plays the signal while automatically deemphasizing it (with attenuation proportional to the degree of emphasis). Locating a Track (AMS*/Direct Access) You can locate the tracks in a number of ways, but only after you have recorded start IDs on the tape (see pages 14 to 16). To use Direct Access, program numbers must be recorded on the tape (see pages 14 and 17). The beginning of the next or succeeding tracks (AMS) NEXT + as many times as you want while playing. For example, to locate the second track ahead, press twice.

Playback Operations 3-856-761-11(2) Playback Using a Timer (Timer Playing) By connecting a timer (not supplied) to the deck, you can start and stop playback operations at specified times. For further information, refer to the instructions that came with the timer. 1 • To specify the time for the start of playing, do Steps 1 to 3 of “Playing a DAT” on page 8.

• To specify the time for the end of playing, do Steps 1 to 4 of “Playing a DAT” on page 8.

• To specify the time for the start and end of playing, do Steps 1 to 3 of “Playing a DAT” on page 8. 2 Set TIMER on the deck to PLAY. 3 Set the timer as required.

• When you have set the time for the start of playback, the deck turns off. When the specified time arrives, the deck turns on and after about 10 seconds starts playing.

• When you have set the time for the end of playback, the deck continues playing, then when the specified time arrives, the deck stops playing and turns off.

• When you have set the time for both the start and end of playback, the deck turns on. When the starting time arrives, the deck turns on and after about 10 seconds, playback starts. When the ending time arrives, the deck stops playing and turns off. 4 After using the timer, set TIMER on the deck to OFF. Playback Operations About Sub Codes In the DAT format, sub codes (i.e., control codes such as start IDs and program numbers) can be written on the tape along with the audio signal. These sub codes allow you to use AMS (see page 13) or Direct Access (see page 13). Since sub codes are written on the tape separately from the audio signal, they have no effect on the audio signal. Start IDs Start IDs indicate the start of a track, and therefore allow you to locate the position of a track precisely. The start IDs are 9 seconds in length (18 seconds in long-play mode) to enable easy detection during fast- forwarding or rewinding. Program numbers Program numbers serve as track numbers. Occupying the same position as start IDs, a program numbers allow you to locate specific tracks. Notes

• The STOP p and PAUSE P buttons do not work during the writing of sub codes.

• Writing and erasing of start IDs and renumbering of program numbers are impossible if the record-protect hole on the DAT cassette is open (see page 7). Writing Start IDs During Recording You can write start IDs either manually or automatically anytime during recording. WRITE

Writing Sub Codes 3-856-761-11(2) Manual Writing of Start IDs During Recording Press WRITE. “ID WRITE” appears in the display for a few seconds and the start ID is written on the tape at the selected position. “START ID” flashes in the display during this time.

START IDStart ID Note The interval between start IDs must be more than 18 seconds(36 seconds in long-play mode). If the interval is less than 18seconds (or 36 seconds), the deck may fail to detect thesecond start ID during playback. Writing the Start IDs Automatically During Recording Do the following procedure to automatically write program numbers along with start IDs at the same position.

• When recording an analog signal with the INPUT switch at ANALOG A start ID and program number are written whenever theinput signal rises above a given level after remaining at amuted or low level for 3 seconds or more.
• When recording a digital signal with the INPUT switch at OPTICAL or COAXIAL A start ID and program number are written whenever anew track is detected while recording a digital signalthrough the COAXIAL IN or OPTICAL IN jack from adigital source such as CD player or another DAT deck.Start IDs and program numbers are not written, however,for tracks that are less than 18 seconds in length. 1 Do Steps 1 to 7 of “Recording on a DAT” on pages 6 and 7. The deck changes to recording pause. 2 Press START ID AUTO repeatedly until “AUTO” appears in the display. 3 If you are recording from the end of the recorded portion, use the number buttons to specify the program number after the last one recorded. Example: When program number 5 is the lastprogram number recorded on the tape.The next programnumberPGM NO. AUTO REC

If the last program number on the tape appears in the display, you don’t have to specify the next program number. If you are recording from the beginning of a blank tape, program number “1” appears in the display. If you forget program numbering at this time, you can add them later (see “Renumbering the Program Numbers Automatically (Renumbering)” on page 17). 4 To start recording, press PAUSE P or PLAY (, then start playing the program source. Start IDs are written on the tape automatically during recording. “ID WRITE” appears for a few seconds whenever a sub codes (a start ID and program number) are being written.

Additional Information 3-856-761-11(2) Writing Sub Codes Renumbering the Program Numbers Automatically (Renumbering) Renumbering searches for each start ID from the beginning of the tape and assigns a new program number to each one starting with 1. Use Renumbering in the following cases:

• When you’ve added a start ID while playing the tape.

• When a program number is missing due to an erased start ID.

• When you began recording from the middle of the tape and wrote a program number that already exists, or when one of the the start IDs has no program number.

+ 0) L R Press START ID RENUMBER while the deck is playing or stopped. “RENUMBER” flashes in the display and the tape is automatically rewound to its beginning. The deck then starts searching for start IDs from the beginning of the tape and assigns a new consecutive program number to each track. When the deck detects a start ID, the deck plays the track from the start ID for 2 seconds, then writes a new program number on the tape. During this time, “RENUMBER” lights up and “START ID” flashes. After Renumbering is finished, the deck rewinds the tape automatically to its beginning, then stops. Note Renumbering may not function correctly when:

• A blank section exists on the tape.

• The interval between two start IDs is less than 18 seconds (36 seconds in long-play mode).

• A start ID exists within 10 seconds from the end of the tape. Additional Information Precautions On safety

• Do not disassemble the cabinet as this may result in an electric shock. Refer servicing to qualified personnel only.

• Should any solid object or liquid fall into the cabinet, unplug the AC power cord before operating the unit any further. On power sources

• Before operating the unit, check that its operating voltage is identical with your local power supply. The operating voltage is indicated on the nameplate at the rear of the unit.

• 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.

Regarding tapes of over 120 minutes Do not use thin-tape cassettes (with a playing time of over 120 minutes) to record important material since such cassettes are subject to the following problems: — Improper threading of the tape after repeated AMS, rewinding, fast-forwarding, or cueing operations. — Incorrect writing and erasing of start IDs. — Sound distortion. For the customers in the U.S.A. For detailed safety precautions, see the leaflet “IMPORTANT SAFEGUARDS.” If you have any questions or problems concerning your unit, please consult your nearest Sony dealer. Cleaning Cleaning the cabinet, panel and controls Use a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine. Cleaning the head and tape path

• Prolonged operation will cause contamination of the head. To obtain the best possible recording and playback sound, we recommend that you use the Sony DT-10CL cleaning cassette (not supplied) to clean the head after every ten hours or so of operation.

• Clean the head with the cleaning cassette when the deck has not been used for a long period of time. Contamination of the head may cause sound drop- out during playback. Using the cleaning cassette 1 Insert the cleaning cassette as you would a normal DAT cassette. 2 Press PLAY (. After 10 seconds, press STOP p. Do not press the REC r or FF ) button for cleaning. 3 Remove the cleaning cassette without rewinding it. You should rewind the cleaning cassette only when it has reached the end. Notes on cleaning

• After 10 hours of operation, “CLEANING” appears in the display for about ten seconds when you turn on the deck. It is recommended that you clean the head and tape path periodically, using this message as a guide.

• Due to the shortness of the cleaning cassette, the counter will not show the actual running time and remaining time of the cassette.19

SBM (Super Bit Mapping) Function During analog recording, the SBM function lowers noise within the frequency band to which to the human ear is most receptive to noise, thereby, sharply expanding the auditory dynamic range of the recorded signal. High-precision pulse A/D converter The deck uses a pulse AD converter and decimation filter to convert an analog signal into a quantized 24-bit digital signal. The deck, like CD players, uses 16-bit quantization, and thus the 8-bit difference results in more precise quantization, more signal information and less quantizing noise than 16-bit quantization. During conversion of the 24-bit data to a 16-bit recording signal, the SBM function boosts sound quality by reintegrating 4 bits of signal information that would normally be lost into the 16-bit signal.

Additional Information 3-856-761-11(2) Guide to the Serial Copy Management System This deck uses the Serial Copy Management System, which allows only first-generation digital copies to be made of premastered software via the deck’s digital input jack. An outline of this system appears below: 1 You can record from digital program sources (CDs,premastered MDs or DATs) onto a DAT or recordable MDvia digital input jack on the DAT or MD deck. Youcannot, however, record from this recorded DAT or MDonto another DAT or recordable MD via the digital inputjack on the DAT or MD deck.CD playerDAT deck MD deckOptical cable or coaxialdigital connecting cableRecordingDAT deck orMD deck First-generationDAT or MDrecorded viadigital-to-digitalconnection PlayingDigital output jackDigital input jackDAT or MDDigital output jackDigital input jackRecordingDAT deck orMD deckDAT deck orMD deckPlayingOptical cable orcoaxial digitalconnecting cableAudio connecting cord Line (analog) output jackLine (analog) input jack Applying the principle of human hearing The SBM function applies the principle of human hearing in the reintegration of signal information. The auditory range of the human ear is generally considered to be 20 Hz to 20 kHz; hearing sensitivity, however, shows greater sensitivity to the range between 3 kHz and 4 kHz, and lower sensitivity to frequencies above and below this range. This principle applies also to quantizing noise as well. By reducing quantizing noise in this particular range, signals can be recorded to produce more expansive sound than is possible by a uniform reduction of noise over the entire audible range. Noise-shaping filter The SBM function uses a noise-shaping filter (see Fig. B) with a frequency response similar to that of the human ear to reduce quantizing noise within the most sensitive frequency range, and to feed back the quantizing error (that is normally lost) back to the input signal, re-integrating the low-end bit information with the high-end bit information (see Fig. A). Fig. A 24-bit informationinputNoise-shapingfilter16-bit SBMoutput

Fig. B shows the improvement in the quantizing noise level when the SBM switch is on (theoretical values). Given a noise level of 0 dB when the SBM switch is off, the improvement in noise level for sampling frequencies lower than 3 kHz exceeds 10 dB when the SBM is activated. Fig. B SBM

SBM OFF Noiselevel (dB) Sampling frequency (Hz) The SBM function operates only during recording. The improved sound produced by the SBM function, however, can be enjoyed during playback, regardless of the SBM switch position or the DAT deck being used.

DAT deck or MD deck 2 You can record the digital input signal of a digital satellite broadcast onto a DAT or recordable MD via the digital input jack on the DAT or MD deck which is capable of handling a sampling frequeny of 32 kHz or 48 kHz. You can then record the contents of this recorded DAT or MD (first-generation) onto another DAT or recordable MD via digital input jack on the DAT or MD deck to create a second-generation digital copy. Subsequent recording from the second-generation copy onto another DAT or recordable MD is possible only through the analog input jack on the DAT or MD deck.
