TASCAM MD-801R/P Mk II 3–1 3 - Menu items The selections that can be made using the MD-801’s menu system affect the operation of many other functions. We suggest that you take the time to look through this section and familiarize yourself with the basic contents, so that you have an idea of some of the options available to you. 3.1 Basic principles of menu operations 1 The menu system is entered using the MENU key [15] . Pressing this key brings up a menu in the display. 2 The JOG/DATA dial [12] is used to select a menu. 3 The SHUTTLE wheel [13] is used to open the menu selected in step 2. 4 The JOG/DATA dial is used to select parame- ters and enter values for the menu. Turn the dial clockwise to increase values, and counterclock- wise to decrease them. 5 “On” and “off” values are selected by turning the SHUTTLE wheel clock wise and counter- clockwise respectively ( Y and N ). 6 A few menus have “sub-menus” which are selected using the JOG/DATA dial, and opened with the SHUTTLE wheel. 7 When a menu item has been set in step 4, turn the SHUTTLE wheel to the right ( Y ) to enter the value and return to normal operation. To “escape” from menu mode without making a set- ting, turn the SHUTTLE wheel to the left ( N ) or press the MENU key. 3.2 Pitch control Pitch control can be set ±9.9%, in 0.1% steps. The default setting is 0.0%. After the menu has been opened with the SHUTTLE wheel, the display changes: See 4.2.13, Varispeed mode for details of pitch control operations. 3.3 Auto cue The auto cue facility allows you to cue the playback position automatically to the first frame where the audio level goes above a trigger threshold (see 4.2.12, Cueing to the first audio position in a track). This menu allows you to set the threshold. The default setting is –54 dB. After the menu has been opened with the SHUTTLE wheel, the display changes: There are nine sensitivity levels available for use with this function: –24 dB, –30 dB, –36 dB, –42 dB, –48 dB, –54 dB, –60 dB, –66 dB and –72 dB. This setting is also used with the Sound Synchro function as the threshold above which recording starts (or below which the unit drops into record ready mode). 3.4 Frame display The frames part of the time display can be turned on or off. There are either 86 or 87 MD frames per sec- ond. The default setting is on. After the menu has been opened with the SHUTTLE wheel, the display changes: The only two options here are on and off. 3.5 Jog loop length As explained in 4.2.14, Jog mode, when locating a point using the JOG dial, playback is looped, start- ing at the provisional jog point. This menu allows you to set the length of the jog loop. The default value is 16 frames (about 0.2 second). After the menu has been opened with the SHUTTLE wheel, the display changes: PITCH CONT ? PITCH> 0.0% A CUE LVL ? A CUE> -54dB FR DSPL SEL? FR DSPL>ON JOG LENGTH ? JOG LG> 16f R
3 - Resume setting 3–2 TASCAM MD-801R/P Mk II The minimum length for the jog loop is 12 frames, and the maximum value is 32 frames. The value is set in 1-frame steps. 3.6 Resume setting When the resume setting is turned on, playback restarts from the point at which it was stopped (or the point at which playback was taking place when the power was cut off). The default is off, which means that when playback is stopped, it will start at the beginning of the disc, unless a track number is explicitly specified. This function, when on, changes the function of the STOP key [5] . When the resume function is on, and the STOP key is pressed in play mode, the MD-801 enters play ready mode. If the STOP key is pressed once again, the MD-801 enters stop mode. After the menu has been opened with the SHUTTLE wheel, the display changes: The options available are on and off. 3.7 EOM disc This menu item affects the output of the MD-801 to a device attached to the parallel port (see 7.1, REMOTE (PARALLEL) connector. When set on, an “EOM DISC” tally signal is transmitted from the parallel port when the end of the disc is reached in playback (or recording, in the case of the MD-801R). When this message is transmitted, the EOM indicator flashes in the display. In this menu, it is possible to select how many sec- onds before the end of the disc this message is to be sent, or to turn the message off completely. The default setting is off. After the menu has been opened with the SHUTTLE wheel, the display changes: The time may be set from 1 to 99 seconds, in 1 sec- ond steps, or set to off. NOTE The EOM tally signal is always transmitted when the U-TOC is updated as the result of a recording operation having been completed, unless this setting is set to off. It is also trans- mitted when recording is halted temporarily. 3.8 EOM track The EOM track is similar to the EOM disc function, as described above. The EOM tally signal is trans- mitted before the end of a track playback, and this menu allows the time before the end to be set, or the disabling of this function (default off). When this message is transmitted, the EOM indicator flashes in the display. After the menu has been opened with the SHUTTLE wheel, the display changes: The time may be set from 1 to 99 seconds, in 1 sec- ond steps, or set to off. 3.9 Timer-controlled playback When this function is enabled, if a disc is in the unit, and the unit is powered up (e.g. from a timer-based switching unit), the TOC is read, and playback starts. The default setting is off. If the resume function is switched on (3.6, Resume setting) playback will start from the point at which playback was last stopped, or at the playback point at which the power was last cut off. If the resume function is off, playback will start from the beginning of the disc. After the menu has been opened with the SHUTTLE wheel, the display changes: The options available are on and off.

3 - Incremental play TASCAM MD-801R/P Mk II 3–3 3.10 Incremental play This function allows auto-cueing of the playback point to the start of the next track when the STOP key [5] is pressed, or a fader stop command is received (on pin 8 of the parallel remote control port [47] ). When this mode is enabled, pressing the PLAY key [6] of the MD-801, or on an optional RC-801 or RC- 8 remote control unit (or the MONITOR key of either of these units), or a PS/2-type keyboard con- nected to the MD-801 will cue playback to the start of the track following the current track, and start playback from there. NOTES While this function is enabled, the TRACK NO. indicator flashes, as a reminder that the func- tion is enabled. The Auto Ready function (see 4.2.11, Cueing the next track automatically), together with the associated commands received at the serial remote control port) is disabled when this function is enabled. After the menu has been opened with the SHUTTLE wheel, the display changes: Choose between on and off, with the default setting being off. 3.11 Serial communications This menu allows the setting of parameters affecting the serial (RS-232C) control port [45] . This menu contains sub-menus, allowing the different parame- ters to be accessed ( DATA dial to show the sub- menus, SHUTTLE wheel to open them). 3.11.1Baud rate From the main menu, the first sub-menu allows the setting of the communications speed (baud rate):When this sub-menu is opened, the baud rate can be selected and set. The default value is 9600. When a sub-menu value has been set with the SHUTTLE wheel, the unit returns to the normal set- ting. 3.11.2Word length The next sub-menu allows the setting of the word length in serial communications: When this sub-menu has been opened, the word length can be set to 7 or 8 bits. The default is 8 bits. 3.11.3Parity The next sub-menu allows the setting of the parity to be used in serial communications: When this sub-menu has been opened, the parity can be selected from off, odd or even parity. The default is for off (no parity). 3.11.4Stop bits The final sub-menu allows the setting of the number of stop bits: When this sub-menu is opened, thje number of stop bits can be set to 1 or 2. The default is 1. 3.12 Check items These are not settable menu items, but allow the checking of various aspects of the MD-801 system. When the following menu item appears, use the SHUTTLE wheel to enter the menu, and the DATA dial to choose the different options. Exit the menu system by turning the SHUTTLE wheel. INCR PL SEL? INCR PL> OFF SERIAL SET ? BAUD SEL ? BAUD> 9600 LENGTH SEL ? LENGTH>8bits PARITY SEL ? PARITY> OFF STOP BIT ? STOP BIT> 1 CHECK ?
3 - Auto track numbering level 3–4 TASCAM MD-801R/P Mk II 3.12.1Spindle motor time Use this to check how many hours the spindle motor has been in operation. 3.12.2Laser pickup time This indicates how many hours the laser pickup has been used for recording. 3.12.3System software version This allows you to check the current system software version. 3.13 Auto track numbering level This allows the setting of the threshold above which a signal received at the AES/EBU jack or either of the analog connectors triggers the start of a new track (see 4.3.4, Track number incrementing). This value can be off, or one of nine values, as detailed below. There should be a period of relative silence (i.e. below the trigger level) of at least three seconds between “tracks” in the source material for this func- tion to operate. NOTE Bear in mind that some classical material, spoken word, etc. may include such periods of silence, and this may cause spurious track divisions. Also, some analog material may be noisy, and the noise may go above the track division threshold. Adjust the threshold level taking these factors into consideration. After the menu has been opened with the SHUTTLE wheel, the display changes: The available settings are: –24 dB, –30 dB, –36 dB, –42 dB, –48 dB, –54 dB, –60 dB, –66 dB, –72 dB and off. The default value is –54 dB. 3.14 Copy ID When recording an MD on the MD-801, the copy ID of the recorded MD can be set for different purposes. The three settings available are: • Copy Free—( Free ) allows unlimited digital copies to be made from the digital recording made on the MD-801 • First-generation copy only—( 1 gen ) allows only one digital copy to be made from the digital recording produced on the MD-801 • Copy prohibit—( Proh ) means that no further digital copies can be made from the digital record- ing produced on the MD-801. After the menu has been opened with the SHUTTLE wheel, the display changes: The default setting is for free copying. The restric- tions apply only to digital copies produced through the COAXIAL port. The copy bit is ignored if the recording is made when the disc is played back through the AES/EBU connector. 3.15 Post-script recording As explained in 4.3.5, “Post-Script” recording, recording can start either from the beginning of the disc (when this function is turned off), or from the beginning of the free space available, i.e. after the last recorded track (when this function is turned on). This function also controls the operation of the replace recording function (see 4.3.6, Replace recording). After the menu has been opened with the SHUTTLE wheel, the display changes: The available options are on and off, with the default being on. S_TIME> 121 R_TIME> 43 SYS> 01.00 A_TRK LVL ?

TASCAM MD-801R/P Mk II 4–1 4 - Basic operations This section gives you informstion about the basic operations using the MD-801. It assumes that you have connected the MD-801 to all the other equipment that you will be using. If you have not already made these connections, read 2.3, Rear panel for details of the rear panel connections, and connect the other equipment appropriately. 4.1 Inserting and ejecting discs Discs are inserted label side uppermost, in the direc- tion of the arrow marked on the disc. The display shows: if the MD-801 is turned on without a disc in the drive. As the disc is loaded, the display shows: When the disc has been loaded, the disc title, number of tracks, total running time, etc. are displayed. Use the EJECT key [3] to eject discs. Discs do not have to be ejected when the power to the MD-801 is turned off. No damage will be caused to discs if they are left in the unit at power-off or power on. NOTE Never turn the power off when the U-TOC is being written to disc ( UTOC Writing ). If you do, the disc may become unreadable. When the MD-801 is turned on with a disc already loaded in the drive, the display will show: before showing the disc title, running time, number of tracks, etc. 4.2 Playback of discs The following instructions apply to both pre- recorded and recordable MD media. 4.2.1 Playing back a whole disc When the disc has been loaded, and the TOC has been read, use the PLAY MODE key so that the playback mode is not set to SINGLE or A-B (see [22] ).Press the PLAY key [6] . Playback will start from the beginning of the disc. Stop playback with the STOP key [5] . Pause playback with the READY key [7] and restart it with the PLAY key. NOTE If the tracks being played back are less than three seconds in length, playback will be dis- continuous (“jumpy”). 4.2.2 Playback outputs There are two sets of outputs provided on the MD- 801: the LINE balanced XLR-type at +4 dBu [40] , and the MONITOR unbalanced RCA at –10 dBV [38] . OUTPUT MODE DIP switch 2 [39] on the rear panel is used to synchronize these outputs so that material is always played back through both sets of outputs (off), or individually (on). If the individual output option is chosen, the PLAY key on the MD-801 itself or the MONITOR key on the RC-801 will start playback through the MONITOR outputs only. In this case, the LINE out- puts are activated following a play or online com- mand from a remote controller (keyboard, RC-801, RC-8 or the serial or parallel controller). If the the LINE outputs are used for playback, the MONITOR outputs may also be used for simulta- neous playback. OUTPUT MODE DIP switch 3 controls this. When set to off, the MONITOR out- puts are muted when the LINE outputs are in use. When set on, the MONITOR outputs are always used. The PHONES jack [9] is always used. The above applies to the analog outputs only, and does not refer at all to the digital outputs, which are always in use, regardless of the origin of the play- back command. 4.2.3 Monaural playback OUTPUT MODE DIP switch 1 [39] is used to com- bine the left and right tracks and output them from both the left and right outputs equally. The outputs affected are the LINE [40] , MONITOR [38] and PHONES outputs. The digital outputs are not affected by the position of this switch. NO DISC Disc Loading TOC Reading
4 - Playback of discs 4–2 TASCAM MD-801R/P Mk II 4.2.4 Playing back a single track When the disc has been loaded and the TOC has been read, use the PLAY MODE key to select the SINGLE play mode (see [22] ). Use the TRACK keys [4] to move the playback posi- tion to the start of the desired track. Press the PLAY key [6] . Playback will start from the beginning of the track. Stop playback with the STOP key [5] . Playback will restart at the start of the disc, unless you move the playback position to the start of the next track to be played back. NOTE The above function can be overridden with the resume function, which turns the STOP key into a “PAUSE” key and allows playback to continue from where it was paused using the STOP key. See 3.6, Resume setting for details. Pause playback with the READY key [7] and restart it with the PLAY key. 4.2.5 Entering the A and B location points 1 Press the MEMO IN/CAPS key [23] so that the indicator lights. 2 Locate the playback point to the first location, and press LOC A/DEL [24] . The indicator will light, showing that a value has been entered into the location, and the MEMO IN/CAPS indica- tor will go out. 3 Locate the playback point to the second loca- tion, and press the MEMO IN/CAPS key [23] again so that the indicator lights. 4 Press LOC B/INSERT [24] . The indicator will light, showing that a value has been entered into the location, and the MEMO IN/CAPS indica- tor will go out. Clear the location points by stopping playback, pressing the MEMO IN/CAPS key, and pressing the appropriate location key ( LOC A/DEL or LOC B/ INSERT ) so that the indicator goes out. 4.2.6 Playback between two location points 1 Enter the location points as described above. 2 Press the PLAY MODE key [22] so that the display shows A-B . 3 Press LOC A/DEL [24] . The unit will locate to the first point, and start playing until it reaches the second point, and then stop. If the location points are in the wrong order (i.e. B precedes A), the display will show A-B Error when playback is attempted. 4.2.7 The CALL function The CALL key [10] is used for easy location to a marked point 1 Put the MD-801 into play ready mode at the point you want to mark (the READY indicator [7] should be lit). 2 Press the READY key. The current point is now marked. 3 You can now play back, or perform the next operation. 4 To return to the marked point, press the CALL key [10] . 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. 4.2.8 Relative time display The call point set in the way described above (4.2.7, The CALL function) can also be used as a zero point for relative time display (all times are displayed relative to this point, with times before the point being displayed as negative values), To enter the rel- ative time mode: 1 Make sure that the MEMO IN/CAPS indicator [23] is lit. 2Press the TIME key [17] to show the different display modes. The relative display mode appears as follows: where xxx represents the “minutes” portion of the elapsed time since the call point, and yy represents the “seconds” portion of the elapsed time. Times before the call point are prefixed with a minus sign. NOTE If no call point has been set, the “relative time” will be from the start of the disc. rel xxxm yys R
4 - Playback of discs TASCAM MD-801R/P Mk II 4–3 4.2.9 Repeat playback Use the REPEAT key [26] to enable the repeat mode as shown in the display ( REPEAT ). The three different repeat modes available corre- spond to the three playback modes set with the PLAY MODE key [22] (whole disc, SINGLE track or A-B points, as set above). NOTE For A-B repeat to be effective, location point A must be before location point B, otherwise A- B repeat cannot take place. 4.2.10Track search operations While playing back, it is possible to press the TRACK keys [4] in order to move forward or back- ward a number of tracks, corresponding to the num- ber of times the key is pressed. After locating to the start of the track (the start of the track start cue point if AUTO CUE is off (4.2.12, Cueing to the first audio position in a track) or the first audio frame if it is on), the deck will park in play ready mode. Pressing the “previous” TRACK key at the first track will move to the last track on the disc, and pressing the “next” TRACK key at the last track will move to the first track on the disc. 4.2.11Cueing the next track automatically When playing back a single track, it is often useful to cue the next track ready for playback. Use the AUTO READY key [20] to enable the unit to enter play ready mode automatically when the start of a track is reached. This is the start of the track as determined by the digital subcode, not the start of the audio signal, unless AUTO CUE is on (see 4.2.12, Cueing to the first audio position in a track). Depending on the play mode (when no repeat is active), the unit will enter stop mode in SINGLE or A- B play mode, and play ready in the “continue” mode, after the location has taken place. If repeat is active, the unit will enter play ready mode at the start of the next track ( REPEAT “continue”), the start of the track which is being repeated ( REPEAT SINGLE ) or the A repeat point ( REPEAT A-B ). 4.2.12Cueing to the first audio position in a track To cue the playback position to the first point where the audio level exceeds a preset threshold, make sure that playback is stopped, press the AUTO CUE key so that the indicator is lit, and then press the READY key. The playback point will then locate to the start of the audio portion of the track (the PLAY indicator will flash while it is locating). If the AUTO CUE indicator is lit, the playback point will automatically locate to the first audio point of the destination track when searching and locating. There are nine “trigger” levels which may be selected through the menu system (see 3.3, Auto cue) for the AUTO CUE operation. Select the appropriate level depending on the source material. 4.2.13Varispeed mode The MD-801 is capable of playing back material in varispeed mode. The speed can be altered to ±9.9% relative to normal speed, and can be changed using the menu system (see 3.2, Pitch control). NOTE While the MD-801 is in varispeed mode, care must be taken that it is not set to use an exter- nal word clock ( [43] ). 4.2.14Jog mode To use the JOG dial to locate a playback point pre- cisely (to frame accuracy): 1 Press the JOG key [11] to light the indicator. 2 Turn the JOG dial [12] (clockwise to move the jog point forwards, counterclockwise to move it backwards). Monitoring is at normal speed. When you stop turning the JOG dial, the sec- tion that has been “highlighted” by the jog action will be repeatedly looped. You can set the length of the jog loop from a menu item (see 3.5, Jog loop length). 3 Press the READY [7] key to set the call point, at the end of the jog loop. 4 Locate to the call point by pressing CALL [10] .
4 - Recording operations 4–4 TASCAM MD-801R/P Mk II NOTE The point at which the JOG key was pressed will not be included in the jog loop. To include this point in the loop, you must turn the JOG dial counterclockwise. 4.2.15Shuttle mode The SHUTTLE wheel [13] allows you to perform fast cue or review operations, moving forwards or backwards through the program material at high speed. The further the wheel is moved from the central posi- tion, the faster the cue or review speed. Since the MD-801 is a digital recorder, playback in cue and review is not continuous. 4.2.16Displaying track titles during playback When the MD-801 is in play or play ready (or in record or record ready) mode, pressing the TITLE key [16] shows the current track title. If the track does not have a title entered, the display briefly shows: If the display is too long to fit on the display, it can be scrolled by pressing the TITLE key once more. NOTE If the MD-801 is in stop mode, pressing the TITLE key displays the disc, rather than the current track, title. Remember also that the MEMO IN/CAPS key can also be used to affect the display (see [16] ). The entry and editing of titles is described in 5.11, Track and disc title entry 4.2.17Displaying the recording date If the current track has been “date- and time- stamped”, the date and time can be displayed: 1 While the MD-801 is in play or play ready (or record or record ready) mode, press the MEMO IN/CAPS key [23] so that the indicator is lit. 2 Press the TITLE key [16] . The word DATE will light in the display, and the date will be shown (for example 98y 12m 25d ), followed by the time (e.g. 10h 34m 12s ) in 24- hour format. If the track has not been time-stamped, the display briefly shows: NOTE If the MD-801 is in stop mode, this operation shows the disc’s time and date, rather than those of the current track. 4.2.18Setting the time and date Since the MD-801 leaves TASCAM with the date and time pre-set, there should be little need for you to set the time and date of the internal clock. However, if you move the MD-801 across time- zones, etc., you may need to reset the date and time following the procedure below: 1 Eject any disc and power off the MD-801 (this step is not strictly necessary, but simplifies the procedure). 2 Press and hold down the TIME key [17] while turning on the power. The display shows: 3 Turn the SHUTTLE wheel clockwise to start setting the time and date. 4 Use the DATA dial as a data entry wheel, and the SHUTTLE wheel as a cursor to move between the year ( y ), month ( m ) and day ( d ) fields, as described in 3.1, Basic principles of menu operations. 5 After entering the value for the day, turn the SHUTTLE wheel: 6 You can set the hours ( h ) and minutes ( m ) here. 7 When these have been entered, press the TIME key to set the time (the seconds value is set to zero as you press the key) and return to normal operation. 4.3 Recording operations Naturally, these recording operations refer to the No Title No Date CLOCK SET ? __y __m __d __h __m --s R
4 - Recording operations TASCAM MD-801R/P Mk II 4–5 MD-801R model only. 4.3.1 General notes on recording using the MD format Because the MD method of recording is somewhat different to a linear recording method, such as tape, you should note the following points. • The message Disc Full may appear on the display before the available recording time on the disc has all be used. This may be because more than 255 tracks have been recorded on the disc. • The sum of the total recorded time, and the dis- played remaining available time may not equal the theoretical total capacity of the disc. This is because of the nature of the MiniDisc track structure. At least two seconds are used for every MiniDisc track, regardless of the audio structure. In addition, “bad sectors”, caused by dirt, scratches, etc. are automatically skipped and ignored, which means that they are unavailable for recording. We always suggest that you leave some “safety net”, and do not attempt to record a program of exactly 74 minutes on an MD marked as 74 minutes. • Erasing a track will not make the time the exact length of the erased track available for recording. This is on account of the nature of the MD recording format, and has to do with block size, etc. If you are familiar with computer systems, you may be aware of a simiular limitation with regard to file size on some operating systems. 4.3.2 Rebuilding the TOC It is possible to rebuild the TOC, which will free up recording space if a heavily-edited disc is being used. 1 With the MD-801 stopped, press the EDIT key [18] . 2 Turn the DATA dial [12] until the display shows: 3 Turn the SHUTTLE wheel [13] clockwise to rebuild the TOC (counterclockwise to cancel the operation). 4 When the display shows Complete , and the TOC WRITE indicator [19] lights, press the TOC WRITE key to write the new TOC to disc. NOTE Depending on the condition of the disc (how many edits have been performed, etc.), it may take a considerable amount of time for the TOC to be rebuilt. In rare cases, the recording capacity of the disc may not be increased, even after the TOC has been rebuilt in this way. • The number of tracks that have been intentionally recorded, and the number of tracks displayed may not match. When the transport encounters dirt or scratches, etc., the current track is ended, and a new track is started. This automatically-created track is marked by the let- ters “ Cont !! ” being added to the end of the track title. This “track” cannot be combined using the editing methods available. To avoid the occurence of such “tracks”, it is important to keep the MD media clean and dust-free. NOTE Every time recording is halted, the TOC is updated. As always, avoid turning off the power while the TOC is being written. In addi- tion, you should be aware that if you have performed editing operations that you do not want to commit to disc, and then do some recording, the edit operations will be saved to disc when recording stops. You may want to eject the disc without writing the edits (see [3] ) before recording, to avoid this situation. Like most other forms of recordable media, MDs incorporate a write-protect tab, which can prevent you from accidentally overwriting precious record- ings. If you try recording with a disc that has had the tab set to the “protect” position (open), the display will show: If you want to record on this disc, you must eject the disc, close the write-protect tab and record again. 4.3.3 Basic recording This gives the basic instructions on how to record. There are a number of different recording-related options which may be selected, as described else- where in this section. TOC REBUILD? W_Protected!
4 - Recording operations 4–6 TASCAM MD-801R/P Mk II 1 Select the recording method (digital or analog) and the appropriate input source. 2 Make sure the unit is stopped. 3 Press and hold down the RECORD key [8] and press the READY key [7] . 4 Adjust the recording level (analog, UNCAL only) so that the meters do not read OVER , even in the loudest passages. 5 Start recording by pressing the PLAY key [6] . 6 When recording is finished, press the STOP key [5] . After recording is finished, the TOC is updated. The date is automatically recorded (as taken from the internal clock). The STOP key may also be used to cancel the record ready mode entered in step 3. 4.3.4 Track number incrementing 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 first 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 incre- mented. 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. 4.3.5 “Post-Script” recording There are two ways of cueing the disc when record- ing. One is “post-script” recording, where recording starts immediately following the last recorded mate- rial. Unlike a linear recorder (tape, etc.) there is no need to cue the medium to the last track. The other is non post-script, which starts recording from the start of the disc, overwriting the whole disc, except for the title. Post-script recording is set using the menu system, described in 3.15, Post-script recording. 4.3.6 Replace recording This function allows recordings to be made on an existing track, if the MD-801 is in ready mode in the middle or at the start of an existing track. Recording in replace mode allows recording on that track. Since the MD format is non-linear, the length of the track does not matter. Recording from the start of the track will replace the existing track, keeping the same track number and title (if any). The whole of the existing track will be erased, even if the replacement material is shorter than the existing track. Recording from part of the way through the track will add a new track with the number of the current track plus one. If you start recording part of the way through the track, the part of the original track from the point at which recording started, to the end of the original track, will be erased, even if the new track is shorter than this portion. 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 first track. 1 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).
