NOTE

Reco rding is an a rt a s well as a scien ce. A successf ul r ecord ing is often judged primarily on the qua l ity of sound as art, and we obviously cannot guarantee that. A company that makes paint and brushes for artists cann ot say that the pain t ings made with their pr od ucts will b e critically well-receiv ed. TASCAM can mak e no g ua rantee t ha t the DA-78HR by its elf will assure the quality of the recordings you make. Your skill as a tech nician an d your ab iliti es as an artist will be significant fact ors in the results you achieve .

1.4 Precautions and recommendations

As with any precision piece of electronic equipment, common-sense precautions apply with the DA78HR.

However, there ar e a few extra precautions which ap ply to the DA- 78 HR, and we suggest that you ma ke a note of the se, to prolong the useful life of the DA-78HR.

1.4.1 Clock source in a di gita l studio

The DA-78HR can be used in a variety of s ituatio ns, and wi th a v ar iety of equipment, either d i gital o r analog.

If you are working with more than one d igital audio unit in yo ur s etup, you should n ote that all units must be driven by the same central clock so urce (“word clo ck” or “word s ync ”) .

If differ ent word clock sources are used throughout the setup, it is actually possible to damage speake rs, etc. becaus e of m ismat ches.

The DA-78HR can be desi gnated as the wor d clock master for your studio, or can be slaved to external word cl ocks, us i ng a convenient fro nt-pan el swit ch and standard BNC co nnectors.

Even though AES/EBU stereo digital audio signals are sel f -clocking, any AES/E BU fo rmat signals con verted and fed to or from the DA-78HR mus t be synchron ized a t word level with the DA-78 HR.

1.4.2 HR re cording an d emphas is

R ec ordings ma de in 24-bit (HR) mode do not use emphasis.

If an attemp t is made to record a digita l signal that contains emphasis u sing either the TDIF or the SPDIF digita l a udio in puts, the display shows

E EM P

EMP (

), and the sig nal is muted.

A di gi tal emp hasis circui t is pr ovi ded, however, for co mpa tibility w ith previous models of DTRS recorder.

No te that if a rec ording using emphasis is dubbed to the DA-78HR via the analo g inpu ts, this signal will need t o be mo difi ed a ppropriatel y.

1.4.3 Environmenta l conditions

The DA-78HR can be op erated in most enviro nments, but we suggest th at you keep the environm ental conditions within the followin g limits:

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

• Relative humidity should be between 3 0% and 80% non-con den s in g

• There should be no strong magnetic fields (speakers, etc.) near the DA-78HR.

• Avoid spra ying polish, insecticides, etc . near the DA-78HR.

NOTE

If you need to clean the DA-78HR, use a soft cloth, moistened if necessary with a little detergent and

TASCAM DA-78HR

1 - Intr oduction to the DA-78H R

water. Do not use abra sive cleaner s or solvents such as alcohol or thinner.

Avoid subjecting the DA-78HR to jol ts, sudden shocks, etc.

NOTE

— IMPOR TANT

If you have to return the unit fo r ser vice or r epair, use t he original packing materials if pos sible. If the un it i s to be transported to a recordin g location, etc., use a suitable transport case with sufficient shock protection.

TASCAM does not accept r esponsibility for damag e resu lting from neglect or accident .

1.4.4 Installing t he DA - 78HR

T he DA -78HR ma y be inst all ed in a s tandard 19” rack, occu pying 3 U of space. Since the DA-78HR is quite h eavy (around bet ween 7 and 8 kg – ab out 16lb.), your rack should be strong and stable to take the weight of the DA-78HR.

The D A - 78 H R sh ou l d be m o un te d wit h th e fron t pane l verti cal .

1.4.6 Three-core power cord

In orde r to mainta in the best possib l e audio quali ty, the DA- 78H R is supplied with a 3-core (grounded) power cord. DA-78HR should be used wi th a grou nded po wer cor d, connected to a suitable electrical groun d, at all times. If it is not, ther e is a possibility that the audio quality will suffer.

1 .4.7 Po w ering the DA-78HR off and on

When powering the DA-78H R off and on, al ways wait for five seconds or more between powering the unit off and tu rning it on ag ain. If the power is switched t oo quickly, the precision power supply may no t provide the po wer of the prop er quality required for record ing .

If power is inadvertently swit ched o ff a n o n quick ly, an d t he po w er su pply do e s no t res p on d pr o pe r l y , switch the unit off again, wait f or five or more seconds, and swi tch i t on again.

1.4.8 Condensati on

If you use the DA-78HR in a warm place after mo ving it from a cold place (for instance, recor ding on location), or if there has been a sudden change in temperature, condensation m ay occur within the tap e mechanism, with a risk of possible dama ge to the unit.

1.4.5 Ele ct rica l co nside rat ions

Make sure th at your local power supply matches the voltage requirements marked o n the rear pa nel of the DA- 78HR.

If you are in any doubt co ncerning the local power supply, consult an electrician .

Av oid ex treme v oltage fluctuation s. If necessary, use an input voltage regulator to smooth the power supplied to th e D A-78HR.

Do not open the unit to clean inside, or to per for m any in ternal adjustm ents . Yo u sh ould not attem pt any cleaning or other maintenance proced ures which are not d escribe d in this manual.

Yo u may need to clean the heads occasi onally. Th e procedure for doing this, and for checking tape error r ates, etc. , is given in 11.1 , “Head an d transport cleaning”.

If condensation does occur, you will not be able to operate the DA- 78H R controls, a nd you will see the following me ssage on the display

E DEW (

E DEW

If you see the above messag e, leave the DA- 78HR s wi t ched on for o ne or tw o ho urs, then sw i tc h i t of f an d on ag a i n before starti ng rec or d i ng .

If you are going to use the DA-78HR in a location where you think condensation is likely to occur, move th e DA-78HR into the warmer location a bout one or two hours before recor ding is d ue to start, and leave it switched on. T urn the DA- 78H R off and th en on again bef ore starting recor ding.

1.5 Recommended tapes

Th e D A-78HR is designed for us e w ith Hi 8 vid eo casset t es. Y ou ca nnot u s e a n y ot h e r ki n d of t a pe w it h the DA- 78H R.

Alwa ys use new tapes, or tapes in the best possible condition, in o rder to achie ve the best possible r esults when recording. Tapes which have been over-used will no t give such good resu lts as ne w tape s.

TASCAM DA-78HR

1 - Introductio n to the DA-78HR

There are two basic ty pes of Hi8 tape: MP and ME. Eac h has its ow n particular char acteristics and merits :

• MP tap es are manufactured using a d aubed magnetic particle deposit proc ess and exhibit a level of perfor mance which is more than acceptable. They have a durability which all ows them to be used as work tapes in st udi o an d post -producti on environme nt s.

• ME ta p es have the i r magneti c la yer p rod uc ed through a metal ev apo ration process. Generally speaking, th ough these tape s hav e a high p erformance level, they are not as robust as MP tapes (see above ) and s hould be us ed fo r l ive recordin g and archival purpo ses, rath er than as work tapes.

TASCAM does not endorse any specific tape or tape manufacturer. TASCAM has licensed th e use of the DTRS logo ( ) to tape manu fact ure rs, provided their tape meets the specifications required by DTRS tap e recorders. The table below lists several suc h tap es, certified for use w ith DTRS tape record ers. However, the use of the DTRS logo on the tape packaging d oes not imply any endors ement of the tape by TASCAM. It is possible that the characteristics and s ensitivitie s of tapes may be changed by the ma nuf acturers with out notice. The bra nds and mode l nu mbers of tapes listed below may not always meet the specifications required by DTRS sy stems for o ptimum performance. TASCAM assumes no responsibility for pr oblems r esulting f rom change s made by a ma nufactu rer to the materials or specifications of its ta pe prod uct s .

The electr ical characteristics of DTRS r ecorders are adjusted and set using Sony Hi8 tape parameters (MP an d ME) prior to shipme nt.

1.5.1 Tape brands

T he follow ing bra nds and models of tape ca n be use d with the DA-78H R. As mentioned above, this list does not constitute any endorsem ent by TASCAM of these prod ucts, nor is it a gu arantee t hat tapes b earing

this brand and model nam e will continue to give optimu m per formance.

The electr onics of DTRS recorders are designed to operate within specific parameter s. The use of a tape with se ns itivity higher or lower than that of ta pes for wh ich th e DTRS recorder was originally designed ma y cause an error in fu nctio nality or prevent the user from gettin g optim um performa nce from the tap e. Always use the shorte s t poss ible t ape for a given project. Do not attempt to use 150-minute or longer tapes in DTRS machines, as the machine will detect the thick ness of tape and automatically eject any tape thinner than r ecommended.

Never attempt to use a tape with the DA-7 8HR that has previously been used in video equipment.

NOTE

— IMPOR TANT

You cannot cut and spl ice DTRS 8mm tapes for editing purposes. Using a spliced tape in the DA-78HR will inv ar iably result in serious dama ge to the heads, requiring replacement. All editing must be done digitally .

This section explains how to connect other equipme nt to the DA-78HR. It is not inte nde d as a complete ref erence to the use of the DA-78HR. See the appropriate sections for f ull details of h ow these connectors are used.

NOTE

S—IMPORTANT

When making connec tions bet ween the DA-78HR and other equipment, w hether audio or control, both the DA78HR and the other equipment m ust be turned wise damage may be caused to t he DA-78HR and/or the other equipment .

Only use T ASC AM-supplied and TASCAM-approved cables when m aking connections to the DA-78HR. T hough the cables and connec tors may resemble computer cables, they serve dif ferent purpos es, and meet a dif ferent set of specifications. The use of cab les other than TASC AM cables will at best c ause the equipment t o work errat ically, and at w orst c ause damage to the equipment .

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

Se lection for the input so urce ( analo g or d ig ital) on a global or individual track basis is made from the menus. See 5.3, “Input sel ect io n” for de t ail s .

3.1.1 Balance d an alog audio conn ection s

All balanced analog input and output aud io connections to the DA-78HR are made through 25-pin Dsub con necto rs.

All th ese audio inputs and outputs are balanced and are rated at a nominal + 4dBu level.

Th is allows convenient and tidy cabling between the DA- 78HR and oth er units su ch as the T A SCA M M1600 series of mixing consoles .

I t is not recomm end ed that you m ake up your own cables—con sult you r TASCAM dealer for availability of sui table ready-made cables ( and see 1 2.1.8, “Cables”). However, we recognize that every situation has its own unique features, and there are occasions when a special cable m ust be made.

Before starting to m ake the cable, we suggest you contact your T ASC AM de aler for full deta ils of cable specifications, etc.

3 .1.3 Digital audi o connect ions

Multitrack digital audio input and ou tput signals are carr ied on a single 2 5-pin D-sub connector. The signals are in TDIF-1 format.

To carry signals between a DA-78HR and another unit eq uipped with TDIF-1 in terfaces , such as the TA S CAM serie s of digital mixing console s or othe r DT RS recorders , u se a PW-8 8D cable (1 me t er lo ng) or a PW-88DL cable (5 meters long).

If you need to connect the DA- 78HR to a digital audio sour ce using a dif fer ent format , we recomm end the us e of the following units:

• TASCAM IF-88AE Interface Unit—converts between the TDIF-1 an d AE S/E B U f orma t s

(8 cha nne ls). It also provides SP DIF f ormat conversion fa c ilities.

• T ASCAM IF-AE8—also provides sophisticat ed convers i on facilities be tween the TDI F-

1 and AES/EBU data fo rmats.

• TASC AM IF-88 SD Int erf ace Un it—converts between the TD IF-1 a nd S DIF-2 digital audio formats.

• The TASCAM IF-TAD—converts betw een the T DIF-1 and A DAT data formats, using a

dig ital optical input/output for th e ADAT d ata.

It sh ould be noted that there is an “invisible ” field to the right o f the frames field . This allows th e who le o f the displayed value to be increm ented, not just the highlighted field. In other words, frame values, etc. will “roll over” and increment the next field to the left. In this mode , there is no flashing dot to indicate the cursor.

R epeate d press es of these keys will a llow the edit ing of the following fields (in order):

Hours ⇔ Minutes ⇔ Secon ds ⇔ Frames ⇔ Frames (with in crem ent o f whole time value ) ⇔ Sub-frames

4.3.6 Sub- f rame values

There are two ways of r epresenting sub-fram e values: as “percentage” subframes, or as s amples.

When sub-frames are displayed as percentages, the mini mum di sp l ayed va lu e i s al w ays 00 and t he max- imum displa yed value is 99.

When displayed as a sample value, the n umber o f samp les per frame varies, according to both the samplin g rate, and the frame rate currently selected:

When moving around a time value in the way described above, moving the “cursor” past the frames field will c hange the d isplay to a sub-frame display.

A s ub-f ram e display shows SF (

There are four modes of sub-frame display:

• Percentage

• Percentage with increment of whole time value

• Samples

• Samples with increment of whole time value I n the two d ispl ay modes where ther e i s an incremen t

of the whole time value , there is no dot displayed. T hese modes are acce ssed , as expla ined above ( 4.3.5 ,
