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.

Sound-muted section

This is a section on which a signal has been recorded but at a level that is not audible.

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.

If you press the REC button while in a blank section

The deck automatically rewrites 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.

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 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.

1 Do Steps 1 to 6 of "Recording on a DAT" on pages 6 and 7.
2 Play the portion of the program source with the strongest signal level.
3 While monitoring the sound, turn REC LEVEL to adjust the recording level so that the peak level meters are at maximum level without entering the OVER (red) range.

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.

(Continued)

Recording Operations

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 -12dB and 0dB .

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 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 rewrites 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.

1 With the deck stopped, press REW to rewind the tape to the beginning.
2 Press FF

The deck locates the end of the recorded portion, then stops.

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.

If you press the REC button while in a blank section

The deck automatically rewrites 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.

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 32kHz with the INPUT switch set to OPTICAL or COAXIAL.

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.

Input signal	REC MODE position	Recording mode
Analog	STANDARD(48 kHz)	Standard play(48 kHz)
	STANDARD(44.1 kHz)	Standard play(44.1 kHz)
	LONG	Long play (32 kHz)
Digital (32 kHz)	STANDARD(48 kHz)STANDARD(44.1 kHz)	Standard play(32 kHz)
	LONG	Long play (32 kHz)
Digital (44.1 kHz)	STANDARD(48 kHz)STANDARD(44.1 kHz)LONG	Standard play(44.1 kHz)(Standard play only)
Digital (48 kHz)	STANDARD(48 kHz)STANDARD(44.1 kHz)LONG	Standard play(48 kHz)(Standard play only)

The recording time in long-play mode (the REC MODE switch set to LONG) is twice as long as standard-play mode.

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 48kHz or 44.1kHz ). For details on the SBM function, see "SBM (Super Bit Mapping) Function" on page 20.

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.

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).

1 Press REC MUTE 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 O 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, "RFC" will begin to flash more quickly and the time elapsed after pressing the REC MUTE O button is shown in the display.

When you release the REC MUTE O button, in the display stays on and the deck changes to recording pause.

2 Press PAUSE 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 crase a start ID (see page 14) that is recorded within 2 seconds from the beginning of the tape.

Recording Using a Timer (Timer Recording)

By connecting a timer (not supplied) to the deck, you can start and stop recording operations at specified times. For further information, refer to the instructions that came with the timer.

1 Do Steps 1 to 7 of "Recording on a DAT" on pages 6 and 7.
2 To specify the time for the start of recording, press STOP.
To specify the time for the end of recording, do Steps 8 and 9 of "Recording on a DAT" on page 7.
To specify the time for the start and end of recording, press STOP.

3 Set TIMER on the deck to REC.
4 Set the timer as required.

• When you have set the time for the start of recording, the deck turns off. When the specified time arrives, the deck turns on and after about 10 seconds starts recording.
• When you have set the time for the end of recording, the deck continues recording, then when the specified time arrives, the deck stops recording and turns off.
• When you have set the time for both the start and end of recording, the deck turns off. When the starting time arrives, the deck turns on and after about 10 seconds, recording starts. When the ending time arrives, the deck stops recording and turns off.

5 After using the timer, set TIMER on the deck to OFF.

Notes

• If TIMER switch is left at the REC position, the deck will automatically start recording when you turn on the deck next time.
• During Timer Recording (i.e., when the TIMER switch is set to the REC position), Auto Rewind (see page 7) will not function even if the tape ends during recording. This is to prevent previously recorded material from being recorded over.

For basic playback operations, see page 8.

About the Display

You can use the display to show the following types of time information:

absolute time
- playing time of the track
- remaining time on the tape
- tape running time

Showing the absolute time, playing time of the track, remaining time on the tape, and tape running time.

Press MODE (or COUNTER MODE on the remote). Each time you press the button, the displayed information changes as follows.

To reset the tape running time

Press RESET (or COUNTER RESET on the remote).

Notes

• When playing certain types of premastered tapes, "BB" may appear momentarily in the display at the beginning of the tape.
  The playing time of the track does not appear in the following cases: When you start playing from the middle of the track During rewinding
• In standard-play mode, the remaining time on the tape appears about 16 seconds after you start playing.
  The displayed remaining time may vary somewhat from the actual remaining time, depending on the tape.

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).

To locate Press

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.
The beginning of the current track(AMS)	PREVIOUS▶ once while playing
The beginning of preceding tracks (AMS)	PREVIOUS▶ as many times as you want while playing. For example, to locate the second track behind, press three times.
By specifying the program number of a track (Direct Access)	1 Enter the program number of the track with the number buttons. 2 Press▶.

• AMS = Automatic Music Sensor.

If you enter the wrong program number during Direct Access

If you haven't pressed the button, press the CLEAR button on the remote, then enter the correct number. If you have already pressed the button, pressing the CLEAR button will not erase the wrong program number. Stop the deck and reenter the program number.

If the deck detects a blank section of 9 seconds or more, or the end of the tape

The deck rewinds the tape automatically to its beginning and stops (Auto Rewind).

You can make the deck start playing automatically from the beginning of the tape after rewinding

Press PLAY while holding down REW

Playing Tracks Repeatedly

(Repeat Play)

You can play a specific track or all the tracks on the tape repeatedly.

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 rewrites 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.

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.

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.

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 and PAUSE 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.

PAUSE II
STARTIDAUTO
WRITE

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.

Note

The interval between start IDs must be more than 18 seconds (36 seconds in long-play mode). If the interval is less than 18 seconds (or 36 seconds), the deck may fail to detect the second 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 the input signal rises above a given level after remaining at a muted 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 a new track is detected while recording a digital signal through the COAXIAL IN or OPTICAL IN jack from a digital 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 last program number recorded on the tape.

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 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.

During digital recording from a CD player

Start recording on your deck first, then press the PLAY button on the CD player while it is stopped. If you place your deck into recording pause and the CD into play pause before you start recording, the start ID and program number of the first track on the CD may not be correctly written to the tape.

Note

During automatic start ID writing the positioning of some start IDs may be inaccurately or inappropriately positioned away from the beginning of the track. If this happens, you can reposition or erase the start IDs later (see "Accurate Positioning of Start IDs (Rehearsal)" and "Erasing Start IDs" on page 16).

Writing Start IDs During Playback

You can write start IDs during playback.

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.

Writing Sub Codes

Accurate Positioning of Start IDs (Rehearsal)

1 During playback, press START ID REHEARSAL when you arrive at the proper position. "REHRSL" appears, "START ID" flashes in the display and Rehearsal repeats a 3-second portion starting from the selected position. Note that the repeated portion will play back 8 times, with the remaining number of times appearing to the right of the "REHRSL". After 8 times, the deck automatically stops.

2 Press REW or FF to move the beginning of the repeated portion. Each time you press the REW or FF button, the beginning of the repeated portion shifts backwards or forwards in 0.3-second increments, up to a maximum extent of about 2 seconds (4 seconds in long-play mode) in either direction.

Position where the START ID REHEARSAL button is pressed in Step 1.

The time in the display shows the shift in position from the time the START ID REHEARSAL button was pressed.

3 Press WRITE. "IDWRITE" 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.

Adjusting the Position of an Existing Start ID

You can adjust the position of previously recorded start IDs.

1 During playback, press START ID REHEARSAL. when the existing start ID you want to reposition is displayed. The deck rewinds to the beginning of start ID and Rehearsal repeats a 3-second portion.
2 Do Steps 1 to 3 of "Accurate Positioning of Start IDs (Rehearsal)" on this page. You can move the start ID to a maximum extent of about 2 seconds (4 seconds in long-play mode) in either direction from its original position.

Note

Start IDs written within 10 seconds from the end of the tape may be difficult or impossible to move.

Erasing Start IDs

You can erase any start ID.

Press ERASE when the start ID you want to erase is displayed.

"ERASE") appears in the display as the deck rewrinds to the beginning of the start ID, then "ID ERASE" appears as the deck erases the start ID.

• It takes 9 seconds to erase a start ID.
• Program numbers are erased together with start IDs.

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 start IDs has no program number.

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 rewrites 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.

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.
• If you are not going to use the unit for a long time, be sure to disconnect the AC power cord (mains lead) from the wall outlet. To disconnect the cord, grasp the plug itself; never pull the cord.
• AC power cord must be changed only at the qualified service shop.

On operation

If the unit is brought directly from a cold place to a warm place, or is placed in a very damp room, moisture may condense inside the unit, "CAUTION" may appear in the display, and the unit may not operate. If this happens, remove the cassette and leave the unit turned on for about an hour until the moisture evaporates.

On placement

• Place the unit in a location with adequate ventilation to prevent heat build-up.
• Do not place the unit: on a soft surface such as a rug that might block the ventilation holes on the bottom.

On the tapes

After using a tape, put it into its case and keep it where it will not be subject to sunlight, high temperature, moisture or dust.
- The DAT cassette shell is designed to keep out dust. Do not open the case to expose the tape.
- The hole at the back of the cassette is the detector slot. Do not cover this slot.

Additional Information

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 dropout 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. Do not press the REC 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.

All buttons do not work during the 9 seconds the start ID is being written (18 seconds in long-play mode). Wait until the writing the start ID finishes before operation.

Absolute time codes writing is not possible.

Recording began within a blank section. Rewind the tape to its beginning, or locate the end of the recorded portion with End Search before starting recording.

Tape transport is excessively loud during fast-forwarding or rewinding.

The noise is caused by the cassette and is not a mechanical problem.

The tape stops suddenly.

The cassette is defective or damaged. Press OPEN/CLOSE and replace the cassette with a new one.

When pressing REW/FF or PREVIOUS/NEXT

▶I, the tape stops momentarily before starting to move.

This is normal and is not a mechanical problem.

The deck cannot be operated with the remote (supplied).

The battery is weak. Change both batteries.

"SBM" does not appear in the display even though SBM is set to ON.

"SBM" appears only during the recording of analog input signals with a sampling frequency of 48kHz or 44.1kHz , not during the recording of a digital input signal, or an analog input signal with a sampling frequency of 32kHz , or during playback.

SBM (Super Bit Mapping) Function

During analog recording, the SBM function lowers noise within the frequency band to which to the human car 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.

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 20Hz to 20kHz ; hearing sensitivity, however, shows greater sensitivity to the range between 3kHz and 4kHz , 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. 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 3kHz exceeds 10 dB when the SBM is activated.

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.

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 MD via digital input jack on the DAT or MD deck. You cannot, however, record from this recorded DAT or MD onto another DAT or recordable MD via the digital input jack on the DAT or MD deck.

Additional Information

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 frequency of 32kHz or 48kHz . 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.

Line (analog) Input jackDigital input jackDigital connecting cable

3 You can record a DAT or MD recorded via the DAT or MD deck's analog input jack onto another DAT or MD via the DAT or MD deck's digital output jack. You cannot, however, make a second-generation DAT or MD copy via the DAT or MD deck's digital output jack.
