APPLICATIONS

The MD-801RmkII could very well be the most advanced MiniDisc recorder ever, giving you the confidence that you'll be ready for anything. Advanced Live Theater - Broadcast Applications - Show Control In live applications, there is no take two; everything needs to happen right the first time. The MD-801RmkII takes advantage of the track names available in the MiniDisc format, since "Train Station" lends a bit more information about the track than "Track 37". Auto Cue will search for the first audio in the track, so you can eliminate lag time between the time you press PLAY and the time you hear it. Auto Ready will stop at the next track ID, preventing the player from rolling right into the next track accidentally. For live applications where a sound cue disk can is assembled in show order order, the Auto Cue function will park at the start of the next cue ready for playback. Broadcast standard fader start function is available in the parallel I/O, as are other remotes and tallies. The MD-801RmkII takes cueing functions a step further by allowing the RCA outputs to be used as a separate cue output. A set of monitor speakers could be connected to the cue output so the audio can be checked without playing through the normal outputs. The MD-801RmkII offers a number of methods for interfacing with show control systems, and offers one of the most robust transports in the business. When the stakes are high, count on the MD-801RmkII. Recording Studio MiniDisc is becoming more and more accessible, offering personal and hi-fi recorders, as well as players for the car. MiniDisc is a wonderful format for creating reference mixes for the ride home from the studio. Plus, with instant start offered with the BU-801 RAM buffer, the MD-801 becomes a powerful tool in assembly editing or sound cue drops.

1.1.3 Random access and U-TOC
The format of a recordable MD is much closer to that of a computer disc than of conventional audio media. The random access nature of the disc media allows a logical track to be composed of sections of audio data recorded at different points on the disc. In the same way that a computers operating system hides the details of the way that data is stored on the
TASCAM MD-801R/P Mk II 11

1 - Care of MD media

disk from the user, and a le appears as one contiguous block of data (even though it may be spread over many tracks and sectors of the disk), the MD player allows separated audio data to appear as a continuous audio track. The MD-801 allows the creation and reading of a User Table of Contents (U-TOC) on recordable discs, which contain instructions to the player on the logical arrangement of the tracks, where to nd the next audio segment to be played, etc. This is similar to the directory tracks provided as part of a computer disk operating system. The random access facilities provided by the MD801 are signicantly better than those to be found on consumer MD decks. The effective start time can be effectively zero, compared with hundreds of milliseconds on consumer units.
1.3 About the MD-801R/P Mk II
The MD-801R/P Mk II, based on the TASCAM MD801 series of MD recorder/players, and designed to meet the requirements of audio professionals, includes the following features: Full editing functions to divide, erase and combine tracks, etc. Auto cue function, allowing the playback point to be automatically cued to the rst frame of a track, using a selectable sensitivity level Auto ready function, allowing the playback point to be parked in the play ready mode at the start of each track A resume function, which holds in backup memory the point where playback stopped, or the power was disconnected Incremental play mode, allowing cueing of the playback point to the start of the next track, as determined by a selectable audio threshold level, when playback is stopped Soft mute eliminates clicks, etc. when pausing and restarting playback Dual time display Three playback modes: normal (whole disc), track play, and A-B play (between two dened points) 3-point autolocation facility Repeat (disc, track, A-B) Either stereo or monaural playback may be selected Pitch change 9.9% in 0.1% steps Shuttle operations up to 100 x normal speed, and jog to single-frame accuracy Digital outputs in COAXIAL (SPDIF) and AES/ EBU Word clock synchronization for inclusion of the MD-801 in an all-digital audio setup Two sets of analog outputs: 10 dBV unbalanced MONITOR (RCA) and +4 dBu balanced LINE (XLR-type). The LINE outputs may be trimmed for precise signal matching with other equipment Output selectable (using remote controllers) from either MONITOR or LINE High-quality DA convertor for optimum analog audio quality Level 4.5 ATRAC system PS/2-compatible computer keyboard connector allows titling and other remote control operations

1.1.4 Track titling, etc.
In common with other forms of digital audio media, the MD medium allows other data to be recorded alongside the audio data. In the MD medium, this is used to provide alphanumeric disc and track titles, which are shown on the display of the player. In the case of the MD-801R/P Mk II, this information may be conveniently entered through a standard computer keyboard (PS/2 compatible), or through the controls of the main unit. In addition, a realtime clock allows date- and timestamping of tracks recorded on the unit or created or edited through TOC editing functions. These times will be displayed when the disc is replayed on any one of the MD-801 series.

1.2 Care of MD media

The MD medium has been designed to be robust, and the integration of the disc into a cartridge protects the recorded surface from the worst effects of dust, ngerprints, and scratches. Even so, there are some commonsense precautions that you should take when storing and handling MiniDiscs. Do not open the shutter and touch the surface of the disc. Do not keep MiniDiscs in excessively dusty locations, in direct sunlight, in areas subject to high temperatures, or high levels of humidity. If the cartridge becomes dirty, clean it with a dry, soft cloth. Do not use any solvents or other liquids.

1.3.2 Rack-mounting the unit
The MD-801 is equipped with integral rack-mount ears, and may be installed in any standard vertical 19 rack. Remove the feet from the MD-801 using a Phillips screwdriver before installing the unit.
In addition, the MD801R Mk II provides the following features: 20-bit A/D converter for increased audio quality when recording Selectable Copy ID modes, including the SCMS standard Integral sampling frequency converter, allowing digital recording from material recorded at frequencies other than 44.1 kHz (48 kHz and 32 kHz) Digital inputs in both SPDIF and AES/EBU formats The ability to record in monaural mode, doubling the recording time available on a disc. Analog inputs in both +4 dBu balanced (XLRtype) and 10 dBV unbalanced (RCA) formats. The balanced inputs may be trimmed to match input signal levels Replace recording function, allowing recording to be carried out in the middle of a track, while retaining the track title Sound sync function to allow the unit to start recording automatically when a selectable audio threshold level is exceeded Title dubbing from another MD-801 unit (requires optional connecting cable PW-1XMD) Realtime clock for date- and timestamping recorded material In addition to the 3U of space required for the MD801 itself, we strongly suggest leaving at least 1U of empty rack space above the MD-801 for ventilation purposes.

This key allows you to return to the point where the READY key [7] was last pressed while the unit was in play ready mode. The unit will return to this point, and enter play ready mode (READY and PLAY indicators lit). See also 4.2.7, "The CALL function".

[15] MENU key

The MENU key is used to cycle through the different menus that allow the setting of different parameters affecting the operation of the MD-801. See 3, "Menu items" for full details of the menus and the different options available in them.
The MD-801R also automatically sets the call point at the point where recording last started. This enables easy return to the point where the recording started, using the CALL key, in order to check a take, etc. It may also be used to locate to the point which has been located with the JOG dial [12].

[16] TITLE key

The TITLE key is used to show both disc and track titles. It is also used to display the date and time when the MEMO IN/CAPS key indicator [23] is lit. See 4.2.16, "Displaying track titles during playback" and 4.2.17, "Displaying the recording date" for details.
[11] JOG key and indicator
Use this key for precise positioning of the playback point, in combination with the JOG/DATA dial [12]. When the jog mode is active, the JOG indicator above this key is lit.

[17] TIME key

The TIME key is used to cycle through the folloiwng time display modes on the upper 7-segment numeric indicators of the display during playback or in play ready mode: (no indication)the time elapsed from the start of the current track R E M A I N the playback time remaining in the current track TOTA L the total elapsed time from the start of the disc TOTA L R E M A I N the total time remaining on the disc It is also possible to make a time display which is relative to a zero point (see the section on 4.2.8, "Relative time display").

[12] JOG/DATA dial

[19] TOC WRITE key and indicator
After an edit operation has been selected and performed from the EDIT key [18], the TOC WRITE indicator will light, and the TO C E D I T indicator in the display will be lit. This is a reminder that the disc should not be ejected before the U-TOC has been written to disc. Press the TOC WRITE key, and the editing data will be written to disc, during which time the TO C E D I T indicator in the display will ash. See the explanation of the EJECT key [3] for details of how to eject a disc without writing the U-TOC, if this is required.
[23] MEMO IN/CAPS key and indicator
This key is used for a variety of functions: entering memory location points, acting as a caps lock key when entering disc and track titles, and as a display mode selector (see [17]), etc. Its uses are described more fully in the various sections dealing with the functions that it controls.
[20] AUTO READY key and indicator
Use this key to put the unit into auto ready mode (the indicator will light). The auto ready mode provides automatic track at a time playback. When in auto ready mode, the unit will go into play ready mode when the start of a track is reached in playback. See 4.2.11, "Cueing the next track automatically" for full details.
[24] LOC A/DEL & LOC B/INSERT keys and indicators
These keys are used to set memory location points, which are used for location, repeat play, editing purposes, etc. These points are retained until the disc is ejected (including at power-off). See 4.2.5, "Entering the A and B location points" for details of how to set these positions. These keys may also be used for locating to the points which have been set. In title editing mode, the A and B keys are used to delete and insert characters, respectively. See 5.11, "Track and disc title entry".
[21] AUTO CUE key and indicator
Use this key to put the unit into auto cue mode (the indicator will light). The auto cue mode allows the elimination of dead time at the start of tracks, allowing easy pre-cuing of commercials, jingles, Foley effects, etc. When the unit is in auto cue mode and stopped, and the READY key [7] is pressed, the unit will search forward for the rst audio frame above a given threshold level, and cue itself to that location. It will then enter play ready mode. A similar process occurs when a track search operation has occurred. See 4.2.12, "Cueing to the rst audio position in a track" for further details.

NOTE The OV E R indicator indicates digital clipping. Digital clipping is a harsh-sounding form of distortion, unlike, say, analog tape saturation, and should be avoided.
When connected to analog equipment, the nominal analog level is referenced to a reading of 16 dB on the meters (see [31]).
(8) TRACK NO. display and indicator
This 3-digit 7-segment display usually shows the current track. It may also be used to show a track number other than the current one, depending on the mode. When the incremental play mode is on (see 3.10, "Incremental play"), this indicator will ash.

(15) REPEAT indicator

Lights when the unit is in repeat playback mode (see [26]).

(16) SINGLE indicator

Lights when a single track has been selected for playback (see [22]).
(9) Time display and indicators
Shows the elapsed or remaining time using a 7-digit 7-segment display (3 digits for minutes, 2 for seconds and optionally 2 for frames). See the explanation of the TIME key [17] for details of the different time display modes.

(17) AB indicator

Lights when the A-B playback mode has been selected (see [22]).

2.3 Rear panel

This section gives details of the connections which should be made to and from the MD-801.

(10) PGM NO.

Lights in programmed play mode (see 6.2.1, "Entering programmed playback") and is used with the last 2 digits of the time display (9).
(11) Dot-matrix alphanumeric display
These dot-matrix elements are used to display alphanumeric information: track and disc titles, time display, menu options, etc. Note that the term alphanumeric is not strictly accurate here, as these elements can also display some punctuation as well as Japanese katakana (2).
NOTES When making or breaking connections between the MD-801 and other units, make sure the power is turned off to all units. This will avoid possible damage to monitoring equipment, etc. caused by transients. The use of analog cables is not recommended for digital audio use, and TASCAM cannot guarantee reliable performance if such cables are used for digital audio connections.

(12) TOC EDIT indicator

Lights in the U-TOC editing modes and after a disc U-TOC has been edited (see [19]) until it is written to disc.
R [32] DIGITAL INPUT (AES/EBU)

This XLR-type connector accepts digital audio data in AES3-1992 format. It also accepts balanced data in the IEC 60958 (consumer) format (SPDIF). The input sampling frequency can be 32 kHz, 44.1 kHz or 48 kHz. The MD-801s internal sampling frequency converter will convert them all to 44.1 kHz for recording.

[38] ANALOG OUTPUTS (MONITOR)
These RCA unbalanced connectors provide output signals at the 10 dBV level. The nominal impedance is 220.
[33] DIGITAL OUTPUT (AES/EBU)
This XLR-type connector outputs digital audio data in AES3-1992 format. The output sampling frequency will always be 44.1 kHz, 9.9%, as determined by the pitch control (see both 4.2.13, "Varispeed mode" and 3.2, "Pitch control").
[39] Analog output function DIP switch bank
This bank of four DIP switches is used to control the outputs from the MONITOR and LINE analog outputs [38] and [40]. They have the following meanings:

OFF (up)

STEREO
R [34] DIGITAL INPUT (COAXIAL)
This RCA connector accepts digital audio data in IEC 60958 (consumer) format (SPDIF). The input sampling frequency can be 32 kHz, 44.1 kHz or 48 kHz. The MD-801s internal sampling frequency converter will convert them all to 44.1 kHz for recording. If switch 4 of the MODE SET DIP switch bank [43] is set off, the signals input here are echoed at the digital outputs [33] and [35] without passing through the frequency converter.

ON (down)

MONO LINE MON ON I N D I V I D UA L
This RCA connector outputs digital audio data in IEC 60958 (consumer) format (SPDIF). The output sampling frequency will always be 44.1 kHz, 9.9%, as determined by the pitch control (see both 4.2.13, "Varispeed mode" and 3.2, "Pitch control").

When O F F , digital signals received at either [32] or [34] are not directly retransmitted. When the switch is set to O N , received digital signals are retransmitted directly from the digital outputs [33] and [35]. This allows autonumbering, etc. to take place using multiple MD-801 units daisy-chained together.

D-IN NORMAL

[41] WORD SYNC IN
This BNC connector accepts a 44.1 kHz word clock (impedance 75 ) at 44.1 kHz (6%).

Use this connector to attach an optional RC-8 remote control unit or to control the deck from a controlling device using parallel protocol.

When recording, the track numbers are incremented automatically in the following cases: When making digital recordings from another unit through the COAXIAL input [34], the PQ code is used when making a recording from a CD player or an MD player, and START IDs are used when recording from a DAT. When making digital recordings through the AES/ EBU input [32] or analog recordings, the Auto track numbering level may be used. The rst time that a signal exceeding the selected threshold is encountered after recording is started, the start of a track is marked, and the track number is incremented. While recording is taking place, if the level drops below the selected threshold for three consecutive seconds or more, and then rises above the threshold, the start of a new track is marked, and the track number is incremented. See 3.13, "Auto track numbering level" for details. When recording from AES/EBU or analog sources, the auto track numbering function may be turned off completely. There are then two options: Record the whole of the material in one take, and use the editing functions at a later time to divide the material into tracks. While recording is taking place, press the next TRACK key [4]. Recording will continue, but the track number is incremented by one, and the track division is written at the point where the next TRACK key was pressed.
NOTE If you want to keep the start of a track on which you are making a replace recording from the middle, use the Track Divide editing function, and start replace recording from the newly-created second track. You can, of course, keep the second part by replace recording the newly-created rst track.
Make sure that the post-script recording mode is on (3.15, "Post-script recording").
NOTE If post-script recording is turned off, you will erase the whole disc (except for the disc title).
46 TASCAM MD-801R/P Mk II
Cue the playback point to the place that you want to start recording. Press the READY key [7] to put the MD-801 into play ready mode. This step is the primary difference between replace recording and ordinary post-script recording. Press and hold down the RECORD key [8] and press the READY key. The display will show:

Replace REC

NOTES If the selected digital input is not correctly connected, or is not present, the D-IN UNLOCK! message will appear on the display to inform you of this. If the digital input signal is interrupted and resumes within 30 seconds of the interruption, a new track will be started on the MD-801, with a number that is one higher than the pre-
TASCAM MD-801R/P Mk II 47
vious one. If the digital signal is not resumed within 30 seconds of interruption, recording will stop. As mentioned earlier, 4.3.4, "Track number incrementing", when digital recordings are made through the COAXIAL inputs, track numbers are incremented automatically as PQ code is read from CD or MD, or START IDs are read from DAT. However, if a source track is less than three seconds in length, a new track will probably not be started on the MD-801.
4.3.10Track title copying together with audio
This is a special case when making copies between two MD-801 units. Titles may be copied in either the analog or the digital copying modes. A special optional cable (PW-1XMD) is required, to link the two serial ports of the two units [45]. Set up the serial communication parameters to the default values, as described in 3.11, "Serial communications", with the baud rate set to 9600. Apart from ensuring that this connection is made, there are no special settings to be made on the master (source) unit. To copy titles along with the audio data:

4.3.9 Analog recording

Set the INPUT selection switch [28] to ANALOG. Set the ANALOG INPUT switch [31] to UNCAL or CAL.
Put the slave unit into record ready mode. Press the RECORD key (again on the slave unit). The display shows:

A-TitleW ON

UNCAL enables the input level controls, while CAL disables them, and inputs the analog signal as given. In this case, a signal input received at nominal level (+ 4dB in the case of the balanced inputs1, and 10 dB in the case of the unbalanced inputs) will register 16 dB. You should take care that analog signals never go more than 16 dB above the nominal level, or clipping will occur. If your program material includes such passages, re suggest that you use the UNCAL setting, and attenuate the signal a little using the input level controls.

Use the TRACK keys, or any other convenient method, to select the second track of the pair to be combined (the selected track will be combined with the one before it). After pressing the EDIT key, turn the DATA dial until the display shows:

COMBINE ?

Set the playback position at the track to be erased (use the TRACK keys or any other convenient way of locating to the track).
Turn the SHUTTLE wheel clockwise to enter the rehearsal mode:

Rehearsal

52 TASCAM MD-801R/P Mk II

5 - Moving tracks

The PLAY indicator above the PLAY key will ash, as will the E D I T indication in the display, to show that rehearsal mode has been entered. In this rehearsal mode, the last 4 seconds (approximately) of the previous track and the rst four seconds (approximately) of the current track are continuously repeated, so that you can audition the join between the tracks. look like:

1 Track number 4

This track is to be moved
Following the move operation, the tracks look like:

New track numbers 4 4

At this point, it is still possible to use the TRACK keys to select another track to be combined. This newly-selected track will be combined with the track immediately before the new selection. Turn the SHUTTLE wheel clockwise to combine the tracks. The display will show Now Editing, followed by Complete.
(track numbers before the move)
The gap is closed up, and all tracks are re-numbered in the new sequence. A move operation can be carried out in the stop, play ready or play modes.
The track number of the rst combined track (i.e. the track immediately before the track selected prior to the combine operation) is used for the combined track. The title of the second track is appended to that of the rst track.
Use the TRACK keys, or any convenient method, to select the track to be moved. After pressing the EDIT key, turn the DATA dial until the display shows:

MOVE ?

Turn the SHUTTLE wheel clockwise to open the move menu. The display will show:

Move to 001?

NOTES Selecting the rst track and attempting a combine operation will result in the message TRK Illegal! being shown on the displayit is not possible to combine the rst and last tracks. Mono and stereo tracks cannot be combined. In some cases where an MD has had many edit operations performed, the Cannot EDIT! message may appear on the display. This does not indicate a fault with the disc or the machine, but is a property of the MD recording system.

This operation can take place in stop, play ready or play mode.
NOTE You cannot move the A-B portion inside itself (i.e. the insert point cannot be between the A point and the B point).
5.8 Restoring erased material
A track or section erased can be unerased. This is an all or nothing-type processall tracks and sections deleted are restored, and it is not possible to restore only one of these tracks or sections. In addition, if tracks or sections are restored, the audio data only is restoredthe titles and recording dates are not restored, but a title such as RST.001 will be automatically given, showing that this is a restored track. The tracks restored in a single operation start numbering at 001, regardless of any other track titles with the same number that were on the disc before the operation. This function can also be used in an emergency, if recording was taking place, and power to the unit was cut off part of the way through the recording process. In this event, data on the disc will be present, but will not be organized with the TOC and will hence be inaccessible. This function may allow the data to be accessed after the restore operation has been performed. However, there are occasions on which this function does not restore such data, and the Not Execute! message will appear.
Press the EDIT key, and turn the DATA dial until the display shows:

RESTORE ?

Turn the SHUTTLE wheel clockwise to restore deleted data.
The display may show Not Execute!. Here, this means that the disc has no material recorded on it which has been erased (there may even be no material at all recorded on it).
5.9 Changing track attributes
After a track has been restored in the way described above, it may have the wrong attribute assigned to it (it may be restored as mono when it was originally stereo, or vice versa ). This function allows you to restore the correct attribute.
Use the TRACK keys or any other convenient method to select the track whose attributes you wish to change. After pressing the EDIT key, turn the DATA dial until the display shows:

TRK ATTR ?

NOTES Tracks and sections of less than 12 seconds in length may not be restored.

5 - Erasing a complete disc
Turn the SHUTTLE wheel clockwise. The display changes:
5.11Track and disc title entry
The disc and tracks can be titled. The titles can consist of upper- and lowercase letters, numbers, and punctuation symbols (as well as Japanese katakana ). Each title can be up to 99 characters long, and titles too long to t on the display are scrolled. The total number of characters which can be included as titles on a disc (disc and track titles) is 1,792 characters. A computer keyboard (PS/2 compatible) can be attached to the MD-801, and used to input titles, or titles can be entered, using the procedure described below (for keyboard operations, see 6, "Use of a keyboard with the MD-801"). Titles can be entered in stop (disc titles), play or play ready (track titles) mode as well as in the record and record ready modes.

If the master MD-801 is in play or play mode, the T R AC K T I T L E indicator will light in the display, and you can copy the title for the current track.
TASCAM MD-801R/P Mk II 59
The MD-801 can be controlled by a number of different sources, including the PS/2 keyboard described in 6, "Use of a keyboard with the MD801". In addition, the REMOTE (SERIAL) [45] and REMOTE (PARALLEL) connectors [47] can be used to connect compatible equipment, and the REMOTE CONTROL terminal [46] allows connection of an optional TASCAM RC-801 or RC-FS10/ 20 remote control unit.
