Microphone recording

A built-in microphone amplifier allows direct connection of microphones to the DA-7

Digital input/output jacks

Built-in digital input/output jacks let you make digital recordings from compact discs digital tane recorders and other digital sources. The digital input/output jacks can be connected to the digital output jacks of another DAT unit for copying of digital codes.

Besides audio data. DAT recordings automatically include special sub-codes on the tape.

There is a variety of possible sub-code data that can be included on a tape depending upon the manufacturer of the equipment used to produce the recording. The Casio DA-7 DAT Recorder automatically registers data to indicate the beginning of each selection (Start ID), the elapsed time from the beginning of the tape, and the elapsed times for each selection. These sub-codes are used during playback for such functions as Skip Play, etc.

Though sub-codes are registered automatically, operating the recorder incorrectly can result in the registration of erroneous sub-codes. Be sure to read the instructions included in this manual carefully before using the unit. For a more details on sub-codes, see page 21 of this manual.

NOTES

*1 Part of the sub-code data included on the tape is used to calculate the elapsed time from the beginning of the tape. To insure that this value is displayed correctly, rewind new tapes to the beginning before beginning recording.
*2 A "recorded blank" is a portion of tape which includes sub-code data only, without any audio data. See page 21 for details.
*³ The AUTO-ID function automatically registers Start ID and Program Number sub-codes onto the tape. These sub-codes mark the beginning of each section and display the sequential number of the selection being played back. See pages 23 and 26 for further details.

To stop recording

Press the PAUSE button to re-enter REC PAUSE. To stop the recording operation completely, press the STOP button.

You will not be able to use the PAUSE button to re-enter REC PAUSE during the few seconds between selections when a Start ID is being registered.

To adjust the recording level

While listening to the sound you want to record while the unit is in REC PAUSE, you can adjust the recording volume level of each channel with the REC LEVEL control. The sound will become distorted during playback if the recording level exceeds 0dB. The level meter holds the peak level for 2 seconds, so you can adjust the level so that the selection will be recorded between -20dB and 0dB. Try to keep the peak level as close to 0dB as possible, without exceeding it.

If you record outdoors, it may be difficult to determine the peak value. In this case, lower the recording level slightly (so that the peak is at about -12dB).

L ....................................

Adjust so that the level does not enter the "OVER" zone on the meter.

Digital recording precautions

To stop recording

"Prohb" shown on the display during REC PAUSE indicates that digital recording is prohibited. It means that digital recording of the data has been disabled at the source (see page 36 for details).
DIGITAL IN flashing on the display can mean that digital data is not being received or that incompatible data (32kHz digital signal) is being received while the unit is in REC PAUSE. Even if you press the PLAY or PAUSE button while DIGITAL IN is flashing, the unit stays in REC PAUSE and "▶" flashes on the display until compatible digital data is received. Receipt of compatible data causes the unit to begin recording automatically. You can stop the "▶" flashing and return to REC PAUSE by pressing the PAUSE button.
Interruption of the compatible digital data during digital recording causes the unit to enter REC PAUSE automatically, with "▶" flashing on the display.
The unit automatically exits REC PAUSE if no key operation is performed or no compatible digital data is received for 5 minutes.
Detection of data whose recording is source-disabled causes the unit to enter REC PAUSE automatically, with "Prohb" shown on the display. Recording of such data can be resumed after setting the INPUT selector to LINE for analog input recording.

Press the PAUSE button to re-enter REC PAUSE. To stop the recording operation completely, press the STOP button.

You will not be able to use the PAUSE button to re-enter REC PAUSE during the few seconds between selections when a Start ID is being registered.

Page 21

Recording mid-way through a tape

Load the tape into the unit and set the time counter (page 33) to the ABS time display.

When preparing to record over a section of tape which already contains recorded data, the ABS time registered on that section of tape will be shown on the display. If no ABS time data was included for the original recording, there will be no display for ABS time. Note that you cannot later add ABS time data to a recording.

When preparing to record from the non-recorded blank following the last selection already contained on the tape, first perform the rewind operation (page 30) to make sure that the record/playback heads are located in the previously recorded section of the tape. Next, stop playback and press the FF button. The fast forward operation will automatically stop at the end of the recorded section of the tape. The ABS time and Program Number data will be shown on the display if such sub-codes were included with the original recording.

Begin Recording.

If the unit was not able to read a Program Number from the original recording, a new program number will not be assigned. In such a case, you will have to renumber programs after you finish recording (page 26).

Page 22

How the DA-7 records data A digital audio tape recorder is capable of recording sub-codes that are separate from the audio data. Sub-codes are used by the recorder to keep track of ABS time, program numbers, and skip play operations. Sub-codes can be registered and edited without affecting the audio data.

About DA-7 There are four types of DA-7 sub-codes. sub-codes

ABS Time

ABS sub-codes indicate the total time elapsed from the beginning of the tape. ABS sub-codes are registered automatically, but the following points should be noted.

When using an unrecorded tape, be sure that it is rewound all the way to the beginning before starting recording.
When recording over a section of tape that is already recorded, be sure to avoid creating any non-recorded blanks (page 22).

Start ID

Start ID sub-codes indicate the beginning of each selection. These sub-codes can be included automatically when the original recording is made, or they can be added later. See page 23 for details.

Program Number

Program Number sub-codes (registered along with Start ID sub-codes) assign a number to a selection. Properly registered Program Number sub-codes assign numbers sequentially, starting with 1 for the first selection on the tape. See page 26 for details.

End Data

The End Data sub-codes indicate the end of the recorded portion of the tape. The End Data sub-code is always registered manually. See page 27 for details.

About Recorded Blanks and Non-Recorded Blanks

Since the sub-code data is independent of the audio data, a DAT recorder can produce two types of blank spaces: recorded blanks (sub-code data only) and non-recorded blanks (no data).

Recorded Blank

A recorded blank is one which contains sub-code data but no sound data.

Page 23

Non-Recorded Blank

A non-recorded blank is one which contains neither sub-code data nor sound data.

As you can see, the non-recorded blank has a break in the sub-code data, so the DAT recorder cannot keep track of the ABS time correctly. Because of this, you should always avoid creating non-recorded blanks on your tapes.

How to avoid non-recorded blank trailers described below to create recorded blank trailers at the end of recordings. To continue recording on such a tape prepared, go to the recorded blanks Use the procedures described below to create recorded blank trailers at the end of recordings. To continue recording on such a tape prepared, go to the recorded blank trailer and start the new recording from there. Before you start recording, check to see that the ABS time is displayed. If it is, the unit is picking up the sub-code data from the previous recording and will automatically continue the sub-code track without a break.
- An End Data sub-code at the end of the recorded portion of a tape is also useful for avoiding non-recorded blanks (see page 27).

To create a portion of the tape. (REC/MUTE) By using the REC/MUTE button, you can create a recorded blank space in any portion of the tape.

<To create a 4-second recorded blank (REC mute)>

When you want to create a recorded blank while recording or while in REC PAUSE, simply press the REC/MUTE button. The LED will flash quickly, and a 4 second space will be created automatically. Then operations return to REC PAUSE.

The REC/MUTE button does not operate while a selection's Start ID is being registered (first 12 seconds of program time).

Page 24

<To create a recorded blank of less than 4 seconds>

There are two ways ( A and B ) to create a blank space less than 4 seconds.

A fter pressing the REC/MUTE button, press the PAUSE button during REC mute. A recorded blank of less than 4 seconds will be created, and operations will return to REC PAUSE.

After pressing the REC/MUTE button, press the PLAY button during REC mute. A recorded blank of less than 4 seconds will be created, and then recording automatically begins again.

<To create a recorded blank of more than 4 seconds>

During recording, hold down the REC/MUTE button. A recorded blank will be created for as long as you hold down the button. When you release the button, operation returns to REC PAUSE.

Registering Start IDs

Start IDs are used to mark a point on the tape as a start point. Then when you use the DA-7's high-speed search function, you can quickly move to any Start ID for playback.

Registration of a Start ID takes 9 seconds.
The Program No. is automatically incremented each time a Start ID is registered.

Page 25

During recording with the AUTO-ID indicator displayed

A Start ID is registered automatically when you start a new recording. You can turn ON the AUTO-ID function by pressing the MODE button during REC PAUSE. The DA-7 automatically registers a Start ID whenever a sound louder than -40dB is picked up following a period of silence (below -40dB) at least 3 seconds long.

• When the AUTO-ID indicator is displayed, you cannot register a Start ID for any selection which is shorter than 20 seconds.

During recording with the AUTO-ID indicator not displayed

A Start ID can be registered manually by pressing the PLAY button, regardless of the volume of the sound being recorded.

When performing direct digital recording with another DAT recorder as the source, the Start ID sub-codes on the original tape are also copied.
When the AUTO-ID indicator is not displayed, you can register a Start ID for any selection which is longer than 12 seconds. For best results, however, we highly recommend that you allow at least 20 seconds between Start IDs.

During playback

You can also register Start IDs at any point in the tape during playback (with the exception of 9-second sections which have already been designated as Start IDs at the beginning of selections).

Stop play approximately 10 seconds before the point where you want to register a Start ID.

Press the MODE button to select the Start ID WRT mode. The "START ID" and "WRT" indicators flash on the display.

3

Press the PLAY button to restart playback. When you reach the desired point, press the PLAY button once again to "write" the point into memory. The Start ID is registered for 12 seconds from that point. Note that the corresponding program number will not be registered. Operations then automatically return to the normal play mode.

Display during registration

Page 26

NOTES

In cases where the space between two Start IDs is too short, search functions may not operate correctly.
The pause function will be inoperative during Start ID registration.
When inputting manual sub-codes, be sure to close the tape erase protect tab.

To erase Start IDs

Stop play immediately before the Start ID you want to eliminate, or use the skip search function to search for the ID and stop in the middle of it (the first 9 seconds of the selection).

2 Pres

Page 27

NOTES

If no Start ID has been registered, search will continue until the end of the tape is reached, and then the tape will automatically rewind and stop.
When Start IDs are registered or deleted manually, be sure to perform the renumbering procedure below.
When inputting manual sub-codes, be sure to close the tape erase protect tab.

Helpful Hints

When you perform the erase procedure during the middle of a Start ID, that Start ID is erased. At any other time, the next Start ID found in search is erased.

Program numbers

By assigning program numbers to each Start ID, you can easily identify and move directly to the beginning of the selection(s) you want to play.

During recording, program numbers are input automatically together with Start IDs. When you start recording mid-way through a tape, it's always best to rewind slightly so the DA-7 can read the previous program number. In this way, all program numbers for succeeding recording will be in sequence with existing selections.

If the previous program number is not read first, a program number will not be registered for the next program.

Renumbering program numbers

When a Start ID is added, program numbers may temporarily be out of sequence. Perform renumbering to bring all program numbers into proper order.

Press the MODE button so that the Renumbering mode is selected. The "RENUM" indicator flashes on the display.

In START-ID area → START-ID Not in START-ID area → - START-ID -(flashing)

2 Press the PLAY button

Selections which have been properly numbered are passed over quickly. When a selection is found to be out of order, a new program number is written (requires 12 seconds). During search the "RENUM" and "▶" indicators flash, while during registration the indicators light. When all renumbering is complete the tape automatically rewinds to the beginning and stops. To stop mid-way through renumbering, press the STOP button while the display is flashing.

Display during rewinding

If an End Data sub-code is encountered during the playback or fast forward operation, the message "EE-End" appears on the display, and the tape is returned to the point immediately preceding the End Data.

Cue/Review Playback During playback, you can "cue" or "review" a selection by holding down the FF or REW buttons. This lets you advance or rewind at 10 times its normal speed (1/10 the speed of normal FF and rewind), so you can accurately find any point in the selection. To return to normal playback, simply release the FF or REW button.

No sound is heard when the Cue/Review function is used, so make use of the time counter for accurate and speedy search. (See page 33 for more information about the time counter.)

Playback Variations

Skip play During playback, stop or pause, you can 'skip' forward or back to other selections by pressing the SKIP buttons.

<To skip from selection 3 to selection 5>

While selection 3 is playing, press the SKIP Forward button 2 times. Playback will skip forward to the beginning of selection number 5.

You can skip up to 15 selections.

<To skip from selection 5 to selection 3>

While selection 5 is playing, press the SKIP Reverse button 3 times. Playback will skip back to the beginning of selection number 3.

The first time the SKIP Reverse button is pressed, playback skips to the beginning of the selection presently in play.
You can skip up to 14 selections.

About Single Repeat Play Single Repeat Play lets you repeat playback of a single selection. Simply hold down the PLAY button for at least 2 seconds while the selection you wish to repeat is playing. The message "PNO" flashes on the display to indicate that Single Repeat Play is activated.

Press any button except the SKIP buttons to cancel Single Repeat Play.
If you do not cancel Single Repeat Play manually, playback of the selection will repeat 15 times. After the 15th playback, the tape will rewind to the beginning of the repeated selection and stop.

IMPORTANT

Single Repeat Play actually repeats playback between two Start ID subcodes. This means that correct operation of this function depends on how Start ID sub-codes are registered on the tape you are playing, as well as from what point on the tape you start Single Repeat Play.
If you start Single Repeat Play before playback of the first selection of the tape starts (before the first Start ID sub-code on the tape is reached), the tape will rewind to the beginning and then stop when the first Start ID sub-code is reached.
If you start Single Repeat Play after playback of the last selection of the tape, repeat playback will be performed between the last Start ID on the tape and the end of the tape (or the End Data sub-code if one is used).
You may have problems using the Single Repeat Play function with selections that are shorter than 18 seconds long.
Start ID sub-codes can be registered anywhere on a tape. This makes it possible to use Single Repeat Play to repeat any section of a tape by first registering Start ID sub-codes to define the section. See page 23 for details on Start ID sub-codes.

Auto rewind

If the end of the tape is reached during the playback, recording, forward skip, or search operations, the tape is automatically rewound to the beginning. If a 9-second non-recorded blank is encountered, however, the tape is automatically rewound to beginning of the non-recorded blank. If an End Data sub-code is encountered during the playback or fast forward operation, the message "EE-End" appears on the display, and the tape is returned to the point immediately preceding the End Data.

Changing the Time Counter

The time counter actually features 5 different functions, which can be selected with the TIME button.

ABS (Absolute time)

Displays elapsed time from beginning of tape

PRG (Program time)

Displays elapsed time from beginning of selection

REM (Remaining time)

Displays remaining time on tape

Counter 300 100 21 A LOI MERILIO

Displays counter numbers in relation to tape revolutions.

TOC (Table of Contents)

Displays the total number of programs in the PRG number display and the total performance time of the tape in the counter number display. (Appears for three seconds before

(Appears for three seconds before ABS display.)

When the TIME button is pressed, display changes as shown below.

ABS (Absolute time)

Press the TIME button so that ABS is selected.

In this case, the display shows that 2 minutes and 35 seconds have elapsed since the beginning of the tape.

(display modes: stop. play, pause, recording, FF, rewind, cue, review)

-dB ∞ 50 40 30	20 12 6 0 OVER
DIGITAL IN ABS PNO	ר א ק, אשריק, איני, א	•

ABS indicates total elapsed time from the beginning of the tape. When using a new tape, be sure to rewind it all the way to the beginning before recording. If the tape is not rewound, ABS will not be registered.

Page 35

PRG (Program time)

Press the TIME button so that PRG is selected. This indicates that 1 minute and 20 seconds have elapsed in the presently selected program (selection).

Note that program time is displayed when a program is played back from its beginning (Start ID). PRG time is not displayed if the Cue/Review, FF or rewind functions are used to start playback in the middle of a selection.

(display modes: stop. play, pause, recording)

REM (Remaining time)

Press the TIME button so that REM is selected. In this case, the display shows that 1 hour and 53 minutes remain on the tape.

Display appears approximately 10 or 15 seconds after beginning of play/recording, as time is required for calculation. During calculation time, a flashing '--' mark appears in the display.

To reset the counter, press the COUNTER RESET button.

In any TIME MODE, pressing the COUNTER RESET button selects the Counter mode and resets the counter value to 0.

Auto "0" Stop

When the counter display is selected, the tape will automatically stop when the counter reaches a value of "0" during FF or rewind. By resetting the counter at a specific point in the tape, you can quickly fast-forward or rewind back to the point automatically.

TOC (Table of contents)Press the TIME button once again when the Counter is displayed. The TOC display will appear, showing the PRG number display and the total performance time of the tape. After three seconds, the Time Counter automatically shifts to the ABS display.

This function is only available with pre-recorded tapes that contain a table of contents. If there is no TOC registered on the tape, the display will shift to the ABS display.

- About Digital Recording Restrictions -

This unit adopts the Serial Copy Management System (SCMS). Unlike previous systems, the SCMS standard limits direct recording from a compact disc to first-generation copies (I-time recording only). SCMS provides you with digital recording capabilities for personal use, without infringing on the rights of copyright holders.

The following shows the restrictions on digital recording that are imposed by the SCMS standard of the DA-7.

First-generation copies only are possible from this type of source, and the tape created cannot be used as the source for direct digital recording. Trying to copy such a tape causes the message "Prohb" to appear on the display, indicating that further direct digital copying is prohibited.

< Recording from digital sources without copyright protection codes >

Unlimited copies are possible from this type of source.

< When the presence of copy disable codes is unclear >

Up to second-generation copies are possible from this type of source. Trying to copy past the second generation causes the message "Prohb" to appear on the display, indicating that further direct digital copying is prohibited.

Page 38

< Source tape recorded from analog input >

Tapes recorded from analog input (including privately recorded tapes) are treated as digital sources with copyright protection codes. This means that copying is limited to the first generation.

CD
DAT tape
FM tuner
Other analog sources

If the "Prohb" message appears on the display telling you that direct digital recording is impossible, you can still record by switching to analog input.
