Section 1.1 - Key features

1 – Introduction

The RC-898 is a fully-featured remote control unit, which allows you to control up to six DTRS units (DA-98, DA-88 or DA-38 units) with a single cable, as well as units implementing the Sony P2 protocol, or using parallel control. As an alternative to parallel control, up to five GPI eventcontrolled units can be connected.

In addition to providing almost all functions available from the front panels of the DTRS units, the RC-898 in some cases actually extends the capabilities of the basic DTRS system.

1.1 Key features

• DTRS units controlled b y the RC-898 are locked to sample accuracy, providing you with a “virtual” digital multitrack recorder, with up to 48 tracks.

• Up to 99 location memori es may be entered (o r captured) and edited to frame accuracy, for marking important points in a recording project.

• Timecode values are entered and edited using a positive- feel numeri c ke ypad.

• The DTRS units’ transport functions, including the shuttle control, are duplicated on the RC-

898. These transport controls may also be used to control the RS-422 or parallel external machine.

• The RC-898 also features a jog dial, allowing frame-by-frame manual location.

• The jog dial can a lso be used as a data entr y control for the entry of location point and other values.

• Auto-punch operations are fully supported. The RC-898 provides one-ke y operation for rehearsal and recording with automated punch points.

• System settings, for the DTR S units an d for the RC-898 itself, are made using a conv enient menu system, and displayed on a clear backlit 20-character x 4-line display.

• The most frequently-accessed setting menus can be assigned to function keys, so that they may be easily recalled.

• Lighted indicators give an instant indication of the status of the most import ant functions.

• All timecode formats are supported, as well as pull-up/pull-dow n, making the RC-898 the ideal choice for po st-production work in both the movie and vide o fields.

• Up to ten diffe rent setups can be stored and recalled, allowing instant re-conf iguration, not only of the RC-898, but also of all DTRS units connected to it.

Some functions of the RC-898 apply to all DTRS recorders, some only to DA-98 u nits, s ome to DA38 units and some to DA-88 units with the SY-88 synchronizer board fitted. Wherever appropriate, this manual will use combinations of the following symbols t o show what operations may be performed with the different units in the DTRS range:

• Relativ e humidity should be between 30% a nd 80% non-condensing

• Avoid spraying polish, insecti cides, etc. near the RC-898.

WARNING

If you need to clean the unit, use a soft cloth, moistened if necessary with a little detergent and water. Do not use abrasive cleaners or solvents such as alcohol or thinner.

• Avoid subjecti ng the RC-898 to jolts, sudden shocks, etc.

WARNING

If you have to return the unit for service or repair, use the original packing materials if possible. If the unit is to be transported to a recording location, etc., use a suitable trans port case with sufficient shock protection.

TASCAM does not accept responsibility for damage resulting from neglect or accident.

Unit Symbol in text

All units No symbol DA-88 with SY-88 DA-38 DA-98

This manual may also make references to the manuals of the DTRS units and the SY-88. In the case of the DA-98 and DA-38, these references will be made in terms of section numbers (e.g. “4.2” and “4-5” respectively). In the case of the DA-88 and SY-88, page numbers will be provided (e.g. “p16” and “p5-7” respectively).

1.4 Precautions and recommendations

As with every precision piece of electronic equipment, common-sense precautions apply with the RC-898.

However, you should note the following points in particular with regard to the operation of the unit:

1.4.2 Battery backup

The RC-898 requ i res no power su pp l y of i ts own, drawing its power from the DTRS units to which it is connected.

Location memories and configuration settings are stored using a battery backup system. The battery should provide power for sev eral years of use. When the battery eventually degrades to the point where it cannot provide enough power to retain settings, the message

Memory Error will

be shown on the display screen (this can be removed by pressing the

ESCAPE

key).

When this message appears, all memories (location memories and configuration settings) are cleared and reset to the default settings.

If you see this message, contact your TASCAM dealer for details of battery replacement. Do not attempt to replace the battery by yourself.

1.4.3 Digital audio cables

When making connections between TASCAM digital audio units, always use genuine TASCAM cables. This applies particularly to any T-DIF dig-

1.4.1 Environmental conditions

The RC-898 can be operated in most environments, but we suggest that you keep the environmental conditions within the following limits:

• Ambient temperature between 5° and 35° C (41° and 95° F).

1-2

ital audio connections between DTRS recorders, DTRS recorders and digital mixing consoles, etc.

WARNING

Only use TASCAM-supplied and TASCAM-approved cables when making such connections. Though the cables and connectors may resemble computer cables, they serve different purposes, and meet a dif f erent set of s pecifications . The use of cables other than T ASCAM cables will at best cause the equipment to work erratically, and at worst cause damage to the equipment.

If the use of cables other than TASCAM cables causes or results in damage, the warranty is voided.

1.4.4 Reference clock in a digital studio

It is likely that the RC-898 will be operated in an environment where there is more than one digital audio source available.

If this is the case, you must make sure that all digital audio sources in the setup are driven by the same reference clock signal (“word clock” or “Word sy nc”).

Section 1.5 - Accessories

If different clock sources are used throughout a setup, it is actually possible to damage speakers, etc. because of mismatches.

1.5 Accessories

Despite the powerful range of functions which may be controlled from the RC-898, the unit is relatively compact. It may be found convenient to mount the RC-898 on a roll-around stand, available as CS-898.

Should you need extension meters from the tape decks, this can be achieved usi ng MU-8824 meter units and appropriate mounting hardware (MK-

8924).

Section 2.1 - Front panel

This section gives a brief ov erview of the front and rear pane l co ntrols and their functions.

2.1 Front panel

[1] REC FUNCTION keys

These keys with integral indicators allow you to set and view the track arming status of up to six DTRS units attached to the RC-898, or f i v e DTRS units and another recorder.

Trac ks 1 through 8 apply to the first unit, 9 through 16 to the second, and so on.

The last eight are used to control tracks 41 through 48 (the sixth DT RS unit) or may be used for the two analog and four digital tracks of a P2 recorder, as marked (A1, A2, and D1 through

). These keys are only available for this purpose when recording is enabled for the P2 unit (see 9.3.5, “Controlling recording operations on the serial unit”). When used to control the P2 unit in this way, the last two are unused.

[2] INPUT MONITOR keys

These keys with integral indicators allow you to set and view the input monitoring status of the tracks of any D A-98 units attached to the RC-898. See section 7.1 of the DA-98 manual for details of the operation of these keys, which function in the same way a s t he keys on t he RC-898.

When the RC-898 is used to control DA-88 and DA-38 units, the keys cannot be used, but the indicators still reflect the current monitoring status, on a track-by-track basis, of the connected units.

[3] ALL SAFE key

This key (with integral indicator) is equivalent to turning off all the When all tracks are safed in this way, the

[5] AUTO MON key and indicator

This key performs the same function as the AUT O MON key on a DA-98. However , the DA-88 and DA-38 are not equipped with a key with this label, so the function is slightly different when controlling one of these units.

Pressing this key is the equivalent of pressing the

This connector is used for the control of the DTRS units. It should be connected to the REMOTE I N/ SYNC IN of the first DTRS unit in the chain.

Only use a TASCAM cable, as supplied with the RC-898, to make this connection. If your DTRS units are at a greater distance than the cable provided (e.g. your machine room is som e distance from your control roo m), consult your TASCAM dealer for details of the availability of longer DTRS control cables.

Section 3.1 - Connection to DTRS units

3 – Connections

This section describes not only the connection of the RC-898 to other equipment, but also provides some information on setting up a digital audio system using the RC-898.

WARNING

All connections to the RC-898 should be made with the power to all units turned off. If this is not done, the operation of the units may become unstable, and damage may possibly occur.

3.1 Conne ction to DTRS units

The RC-898 and DTRS units form a “daisychain”, with the RC-898 being at the head, and the “tail” unit being terminated with the terminator supplied with the RC-898.

NOTE

When you connect a number of DTRS units which are of different types, including DA-98s, the DA-98 units should be at the head of the chain immediately following the RC-

898. Any DA-38 and DA-88 units s hould then be connected following the DA-98s. If there is more than one DA-98 in the chain, they should be connected together, before the DA38s and DA-88s. The order of the DA-38 and DA-88 units is not important.

If a DTRS unit other than a DA-98 is used as a master unit, the automatic Output TC Source function and Timecode Offset functions of the DA-98 may not work correctly (see the DA-98 Owner’ s Manual, 10.5 and 13.2). In additoin, remote control operation may not work correctly.

If the DTRS units are DA-88s and DA-38s only, they may be connected in any order.

However, if you are operating a mixed set of DA-38s, and DA-88s fitted with the SY-88 synchronizer board, we suggest that the SY-88-equipped DA-88 should follow the RC898, allowing it to serve as a timecode slave, and a DTRS chase master for the DA-38s.

Use the suppled cable to connect the RC-898 to the REMOTE IN/SYNC IN of the first DTRS unit, and a PW-88S cable to connect the SYNC

OUT of the first unit to the REMOTE IN/SYNC IN of the next unit, and so on, until the terminator

is connected to the SYNC OUT of the last unit in the chain.

Tighten the screws holding the cable connector to the RC-898 and to the DTRS unit. This will prevent accidental disconnection of the RC-898 in the middle of a session.

WARNING

Use only TASCAM cables to connect the RC-898 to the first DTRS unit, and to connect the DTRS units to each other. If the use of cables other than TASCAM cables causes or results in damage to the units, the warranty is voided.

No power connection is needed for the RC-898. All power for the operation of the RC-898 is supplied by the first DTRS unit.

NOTE

The TASCAM TM-D8000 digital mixing console also allows the control of DTRS units. However, it is not possible to use a TM-D8000 and RC-898 for control of DTRS units in the same setup. Naturally, however, a TM-D8000 console can be used to mix the audio to and from DTRS units controlled by an RC-898 unit.

3.1.1 Machine IDs

Set the machine IDs of the DTRS units so that the IDs run in a sequence from the unit at the “head” of the chain, closest to the RC-898 (lowest possible ID) to the “tail” unit (highest ID). There should be no gaps in this sequence.

A DA-88 uses a rotary switch to set the ID and uses 0 as the lowest ID, and a DA-38 or DA-98 uses software to make this setting, and uses 1 as

3.4 A note on sy stem clocks

When working with many digital audio units, all these un i ts must be fed from the same cl ock source (either word or video). If this is not done, there is a risk that speakers, etc. may be damaged.

Note that this clock master is entirely different from the timecode master in a studio setup. It is perfectly possible for a clock slave to be a timecode master and vice versa.

3.5 Memory and batteries

As you have noticed, the RC-8 98 requires no power supply of its own, drawing its power fr om the DTRS units to which it is connected.

Location memories and configuration settings are stored using a battery backup system. The battery should provide power for several years of use. When the battery eventually degrades to the point where it cannot provide enough power to retain settings, the message be shown on the diaply screen (this can be removed by pressin g t he

When this message appears, all memories (location memories and configuration settings) are cleared and reset to the default settings.

4.5 Storing and re ca lling user setups

The RC-898 allows you to store and recall almost all parameters set using the menu system, so the same remote control unit can be used with a variety of different equipment setups with the minimum of reconfiguration.

This is a great time-saver, as not only are the RC898’s parameters stored and recalled, but the settings for the DTRS units connected to the RC-898 are also stored and recalled. In this way, up to six DTRS units can be reconfigured to preset configuration patterns with the press of one key.

5.1 Transport controls

The transport controls on the RC-898 replicate those on the DTRS units.

The logic of the transport controls is such that any mode can be entered from any other mode. There is no need to go through

The Hi8 tapes used in DTRS units must be formatted. This can be done either from the DTRS units themselves, or from the RC-898.

It is possible to record audio and format a tape at the same time. This is done by arming the tracks before step 5 above. However, if you do this, you should not interrupt the formatting proces s half way through a tape. Once you start formatting a

tape from the beginning, you should wait until the end of the tape before rewinding and ejecting it.

NOTES

The display shows a negative ABS time for a few seconds at the beginning of the tape. While a negative time is shown, no audio can be recorded on the tape.

We suggest that you leave a blank header of at least 30 seconds at the beginning of the tape. This can be marked as a virtual “zero point” if you like (see 6.3, “Setting a relative time reference”).

5.1.3 Arming tracks

The tracks of the DTRS units are armed using the

These keys and indicators only work for tracks of units that are actually connected.

Before recording, you should make sure that eit her di gital or analog inputs, as required, have been selected (see 7.2.9, “Input selection”) and the appropriate clock settings have been made (see 7.2.6, “Clock selection”).

keys with their indicators.

5.1.5 Transport controls

The RC-898 shares a common interface with all DTRS units with regard to transport functions (including entering end exiting record mode). Consult the relevant portions of the DTRS unit manual if you are unsure of the way in which transport operations are carried out.

One exception to this is the

LOC

key [41] which does not appear on the front panel of DTRS units. It is used to locate the tape to the value shown on

LOCATE TIME/V AL UE

the

display [15]. For full details of how this key is used and the location facilities av ailable fr om the RC-898, see 6, “Location functions”.

5.1.6 Shuttle mode

The RC-898 incorporates a jog dial and shuttle wheel to allow precise positioning of the tape in the DTRS units.

When the lit, moving either of these controls will control the selected unit(s) appropriately.

When the currently-selected unit is recording, the jog and shuttle controls are disabled (this prevents accidental interruption of a take).

The shuttle wheel allows forward motion at the following speeds (relative to normal speed): 8 x, 4 x, 2 x, 1 x, 1/2, 1/4. The same speeds, except for 1 x, are available in reverse mode. The further the shuttle wheel is turned away from the center position in either the clockwise or counterclockwise direction, the faster the tape will be moved.

The jog dial allows very precise positioning of the tape to frame accuracy .

Monitoring during shuttling is explained below (see 5.2.3, “Shuttle monitoring”).

5.2 Monitoring

The monitoring of off-tape and in put source signals is complex, and varies a little between the DA-88 and DA-38 units, and the DA-98 units, due to the latter being provided with track-by-track switching facilities between source and off-tape monitoring, as well as the confidence mode method of off-tape monitoring while recording (see 7.2.12, “Confidence mode”).

6.1 Refer ence modes

Before proceeding with an explanation of the way in which location operations are carried out, it is necessary to examine the way in which times are displayed on the RC-898.

The RC-898 can use one of three time reference modes to show the tape times of the DTRS units connected to it, as shown on the timecode indicators [12]:

Cue points may be set “on-the-fly” or entered manually , and copied from a cue list. All cue points may be edited and “trimmed” to frame accuracy.

the ABS mode, which increase the flexibility of the system. These are described in 8.1.2, “Synthesizing timecode from ABS times”, and allow you to start with an offset, etc. when synsthesizing timecode.

6.4.1 A note on ABS frame rate

When ABS is selected, the number of frames per second is different from that in any timecode mode. For details of setting SMPTE/EBU frame rates, see 8.1.3, “Selecting a timecode type”.

Timecode (whether SMPTE or EBU) contains a fixed number of frames per second. However, the ABS method of timing works in a slightly different way.

As mentioned above (6.3, “Setting a relative time reference”), location

is used for special pur-

poses, such as storing the “zero” reference point in relative time mode. We therefore suggest that you do not use location memory

as a general loca-

tion point.

NOTE

Location memories stored on the RC-898 are completely independent of either the MEMO 1 and MEMO 2 points stored in the DTRS units, or of the 10 extra memory locations which may be stored in a DA-98 unit.

This section covers the operations which relate to the DTRS units, other than those specifically related to timecode.

7.1 Track operations

The following series of operations relate to individual tracks of the DTRS units connected to the RC-898.

7.1.1 Track delay

When recording or playing back, tracks on a DTRS unit may be delayed by up to 7200 samples, or advanced relative to other tracks up to a value of 200 samples.

This is possible due to the design of the recording and monitoring heads in the DTRS mechanism.

As well as external inputs, tracks which have already been recorded can be used as recording sources. This feature therefore allows tracks to be copied within a unit.

It does not allow routing or copying of tracks between machines, nor does it allow the combination (“ping-pong” of tracks). For these operations, an external patching or mixing system is required. For further details of this feature, consult section

7.2 Unit-related functions

The following functions affect the settings of the whole unit, on a unit-by-unit basis.

7.2.1 Chasing to ABS sync

Units which are not the first unit in the chain will typically chase the first unit in the chain using the ABS synchronization facility.

This is different from chasing to timecode, which is described in 8.1.8, “Chasing to external timecode”. Chasing to a DTRS master requires that there is a properly-terminated sync and control

7.2.3 Chasing with an offset

It is not always required that the DTRS units are in perfect synchronization with each other.

For instance, it may be that three DTRS units are being used for video post-prod uction purposes. The dialog and F ol ey tra cks of a proje ct ha v e been recorded on one DTRS tape (up to eight tracks), and the backing music has been recorded on two more tapes (16 tracks). Obviously, the units replaying the two music tapes should be synchronized to each other, but the music may need to be “slipped” relative to the dialog and Foley unit (which is, in turn, synchronized to the timecode on the video, as described in 8.1.8, “Chasing to external timecode”).

Once the dialog and Foley is synchronized to the video timecode, “slipping” the two music units is accomplished in the following way:

3) Use the numeric keypad to enter an offset value which is shown on the display. The

+/-

key of the numeric keypad is

LOCA TE TIME/V ALUE

used to change between positive and negative values.

The offset value may be ±2 hours relative to the mast er t ime.

You can also use the cursor keys to ent er a value directly on the display screen.

NOTE

There is an “invisible” field immediately to the right of the frames field. If you place the cursor there and increment or decrement the value, you can change the time as a whole (as the frame field passes its maximum value, the seconds field will increment).

The Auto Offse t func tion d escri bed bel o w can al so be used to set the offset.

4) Transfer the value to the display screen by pressing and holding down the and pressing the

3) Locate the two tapes (master and slave) so that they have the right offset.

You can play up the tapes and pause them once they have been lined up, or carry out the next step while either or both of the tapes is being replayed.

4) Press either the UP or DOWN key at the correct offset time to capture and store the offset.

7.2.5 Checking the offset

The offset of a slav e DTRS unit relative to its master may be checked (“absolute” difference), as well as the difference (if any) between the intended offset and the actual offset (“relative” difference). In practice, usually there will be no difference between the intended and actual offset, resulting in a relative difference of zero.

As an example, consider the following:

A slave machine has its offset set to +00:10:00:00, and while chasing, the two machines’ tape counters read as follows:

7.2.7 Output timing

On the DA-88, regardless of whether an SY-88 synchronizer board is fitted or not, there is a facility to use either Digital or Analog output mode for exact synchronization when dubbing between DTRS units, etc.

Note that while it is possible to output both digital and analog signals simultaneously, there two sets of signals will be out of sync with each other.

Here, the difference between the master and the slave times (the “absolute difference” is now 00:10:00:04, and this is what is shown if we examine the absolute difference.

However, the result of subtracting the intended offset from the absolute difference is 4 frames, and this is the “relative difference”, which may also be examined as described below:

If you select a value higher than 16, you may want to experiment with the Dither settings (see

7.2.11, “Dither”, bel ow), as this may help with distortion, though a little may be lost from the signalto-noise ratio.

7.2.11 Dither

Dithering, in digital audio, is the tech-

38 98

nique of adding a known noise signal to a lowlevel input signal, especially when converting from a word length with a higher number of bits than the destination (see 7.2.10, “Word length” above).

Paradoxically, this technique removes quantization noise and improves overall distortion figures, though at t he slight e xpense of t he signal-t o-noise ratio. The DA-38 implements an “on/off” dither function, and the DA-98 allows two “shapes” of dither. See se ction 4-8 of the DA-38 manual or

7.2.12 Confidence mode

The DA-98 allows of f -tape monitoring while

recording (confidence mode). This can be switched on or off on a per-machie basis.

However, since there is a slight delay between the input signal and its replay in confidence mode, you should not use confidence mode in the following circumstances:

• When making punch recordings, as you will not be able to hear the exact timings for punch operations.

• When operating a mix ed chain of DA-98s and other units. The delay introduced by conf idence mode on the DA-98 will make these tracks appear to be out of time with the other tracks.

Howev er, confidence mode can be very useful when making test recordings so that you can instantly hear the effects of different dither settings (see 7.2.11, “Dither”), or to monitor possible clipping at high recording levels on a test take, allowing you to “back off” the lev el a little before making a final recording.

functions available through the RC-898. Note that while the RC-898 contains no timecode generator or reader of its own, it is able to control the timecode generators and synchronization facilities of DA-98 and DA-88/SY-88 units. Since the DA-38 does not have any timecode facilities, this section does not have any relevance if you are using a setup composed of only DA-38 units.

Note that in this section, we use the term “timecode” to refer to SMPTE/EBU timecode rather than to ABS timecode.

When using a chain of DTRS units which are to be synchronized to external timecode, you will usually need to synchronize the first unit in the chain. The other units should then chase to the first, using the DTRSABS synchronization facility. For information related to this and to other non-timecode-related synchronization features, see 9, “External control and settings”.

8.1.8 Chasing to external timecode

When chasing to an external timecode source (remember that you cannot chase to MTC), there are two cases to be considered. The first is when the DTRS unit which will be chasing timecode is the first unit in the chain. In this case, there is no DTRS sync signal received at the

SYNC IN

nector (of course, the RC-898 provides control signals), and hence, pressing the

CHASE

will automatically synchronize the DTRS unit to the incoming timecode.

The reference to which the incoming timecode is matched, however, depends on the

Mode

settings of the DTRS unit with regard to

Time

ABS or timecode (see 6.4.2, “Selecting Time Mode”).

In the case of a unit which is connected to the master DTRS unit in the chain, the situation is a little more complex, as the unit must be set up to slave to incoming timecode rather than the DTRS sync signals. Here, the

Time Mode

used once again (6.4.2, “Selecting Time Mode”), but here it determines the chase sync source; timecode or ABS sync.

Note that it is unlikely that you will need to synchronize a slave unit with timecode—typically, only the first unit in the chain will be a timecode slave, and this will act as a DTRS sync master for the other units in the chain.

8.1.9 Chasing with a timecode offset.

NOTE

This procedure described here should be us ed when chasing to timecode. When slave machines are chasing to DTRS sync from a master DTRS unit, use the procedure described in 7.2.3, “Chasing with an offset”.

If the timecode on the DTRS unit matches the timecode coming from the master unit (e.g. the DTRS tapes contain a video soundtrack and have been striped either concurrently with, or from the video tape), there is no need for an offset.

If, howe ver, the DTRS tracks are not linked in this way with the master source, an offset is required. The offset can be timecode. Timecode “wraps” in a 24-hour clock format, so th at 12 h ours in adv a nce o f 13:0 0:00:0 0 is 01:00:00:00, and 12 hours behind 02:00:00:00 is 14:00:00:00.

It is sometimes useful to be able to reference different clock timings for the different DTRS units in the chain (if one unit is recording digital input from another digital source and another is referenced to video, for example).

3) Locate the two tapes (master and slave) so that they have the right offset.

You can play up the tapes and pause them once they have been lined up, or carry out the next step while either or both of the tapes is being replayed.

4) Press either the UP or DOWN key at the correct offset time to capture and store the offset.

NOTE

In a system with multiple digital audio devices, the same clock should be used by all units which are to perform digital audio transfer (e.g. dubbing, etc.). If units have different reference clocks, you cannot transfer digital audio between them.

8.2 Advanced timecode functions

The following functions are designed to extend the capabilities of the DTRS system under various circumstances when working with timecode-based setups. These functions are described more fully in the DTRS manuals. Refer to the appropriate sections of these manuals for further information, if required.

8.2.3 Pull up and pull down

When using DTRS units in NTSC telecine situations, it may be necessary to adjust the sampling frequency fractionally, as the NTSC frame rate of

29.97 and the cinema frame rate of 24 do not form a neat mathematical ratio.

The sampling frequencies of 44.1kHz and 48kHz are therefore affected when the material is transferred back to film.

8.2.4 Error bypass

When a DTRS unit is chasing timecode from an external source, the source timecode may drop out for a fe w frames or be otherw ise dis continu ous. To allow for this, a “flywheel” facility is provided, which allows the DTRS unit to continue for a set period until timecode is received again. The flywheel period may be set for either 10 frames or 30 frames, in the following way:

8.2.5 Rechase mode

The DA-98 provides another facility which is

used when chasing to timecode.

Section 8.2 - Advanced timecode functions

When the DA-98 is chasing timecode, it can be set to lock to timecode once and run freely , or it can constantly monitor the timecode, and issue “speed-up” and “slow-down” messages to its transport to stay in sync. However, if an external or video clock is used as the clock source, the playback output will be muted while the DA-98 is adjusting the speed. If you select the rechase mode (which you may wish to do if there are gaps in the timecode), you can select a “window”. Only if the difference between the received timecode and the DA-98 position falls outside this window, the DA98 will rechase. However, the D A-98’s timekeeping is almost always good enough for you not to need to rechase. See 10.7.9 of the DA-98 manual for further details of this facility.

8.2.7 MIDI Timecode output

Both the DA-88 and DA-98 output MIDI Timecode (MTC) from their MIDI OUT jacks, which echoes the linear timecode output from the timecode outputs.

However, the DA-98 allows you to choose under what circumstances MTC will be output. You can choose not to output MTC at all, to output while fast winding as well as during placyback and recording, or to output MTC while the tape is stopped (this is possible because MTC is indirectly derived from an off-tape signal). For further details of this facility, see section 10.4.5 of the DA-98 manual.

8.2.9 Individual recording status while

However, if DA-98s are being used as slave units, and they are chasing using timecode rather than ABS sync, it is possible to set them so that their recording statu s can be turned on and off individually.

8.2.10 Video resolve

The timecode clock of a DA-98 may be set to resolve to a video signal received at the unit’s VIDEO IN terminal. This means that the timecode frame boundaries will be aligned with the frame boundaries as received in the video signal.

This is a completely different function to the synchroniza tio n of th e word cloc k to v ideo ( se e 7 .2. 6, “Clock selection”).

In addition, if video resolve is enabled, the unit can be set to track the frame boundaries constantly and rechase if it drops out of sync (re-sync), or can be set to a “lock and forget” mode (free), in a similar way to the rechase options available for timecode (see 8.2.5, “Rechase mode”). In re-sync mode, output will be muted while the unit changes speed to match frame boundaries.

See section 10.6 of the DA-98 manual for further details regarding this function.

NOTE

The exact level of control possible by using the RC-898 depends on the implementation of the P2 protocol by the device. Refer to the unit’ s documentation for details of what control is possible through the serial connection.

When a device is selected for control in this way, the REC FUNCTION keys can be used to arm the two analog and four digital tracks, as defined b y the P2 protocol, depending on the settings made in 9.3.4, “Split mode on the serial unit” and 9.3.5, “Controlling recording operations on the serial unit”. The mapping of these tracks to the actual tracks of the unit is determined by the implementation of the protocol by the unit.

9.3.2 Location pre-rol l on the serial uni t

The unit controlled by the serial port may have a pre-roll time which is set independently of the pre-roll time used by DTRS units. This allows the unit to be parked optimally for lockup when locating to cue points:

Howev er, in a video post-production situation, it is quite likely that you will need to control the transport of a VTR, which acts as a timecode master for the DTRS slaves. These DTRS slaves will be used for recording, but the VTR will not (otherwise the worktape will be erased!). The RC-898 therefore provides you with a “split mode” in which all transport keys except the and the

9.4 Other DTRS control functions

The following fu nctions described DTRS f ea-

tures which relate to control, but ar e not timecoderelated. The RC-898 can only perform these functions on D A-98 units. Some of these functions are available on DA-88 units, but they cannot be controlled from the RC-898.

9.4.1 Choosing a control protocol

The DA-98 can be controlled from a variety of

external sources as well as the RC-898. These sources are: P2 protocol (9 pin), MIDI Machine Control, and a bus protocol carried over the RS422 cable and produced by, for example, the TASCAM ES-61 editing controller. See section 11.0.1 of the DA-98 manual for further details relating to this function.

This mapping of DA- 98 tracks to controller tracks does not imply any correspondence between the user interface of the controller and the DA-98 tracks. It refers, rather, to the relationship between the command signals transmitted by the controller and the DA-98 tracks.

To determine which command is used by your controller, and for further details regarding this function, follow the instructions in section 11.1.5 of the DA-98 man ual.

The high (1 00 x) wind speed of the DA-98 means that if the second method is used, the tape will almost invariably overshoot each time and lever locate correctly. Accordingly, a slower (8 x) wind speed is provided which allows for location using the “wind and shuttle” mode.
