be read before the product is operated.
2) Retain Instructions
— The safety and operating instructions should
be retained for future reference.
3) Heed Warnings
— All warnings on the product and in the operating
instructions should be adhered to.
4) Follow Instructions
— All operating and use instructions should be
followed.
5) Cleaning
— Unplug this product from the wall outlet before cleaning.
Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for clean-
ing.
6) Attachments
— Do not use attachments not recommended by the
product manufacturer as they may cause hazards.
7) Water and Moisture
— Do not use this product near water — for
example, near a bath tub, wash bowl, kitchen sink, or laundry tub; in a wet
basement; or near a swimming pool; and the like.
8) Accessories
— Do not place this product on an unstable cart, stand,
tripod, bracket, or table. The product may fall, causing serious injury to a
child or adult, and serious damage to the product. Use only with a cart,
stand, tripod, bracket, or table recommended by the manufacturer, or sold
with the product. Any mounting of the product should follow the manufac-
turer’s instructions, and should use a mounting accessory recommended by
the manufacturer.
9)
A product and cart combination should be moved with care. Quick stops,
excessive force, and uneven surfaces may cause the product and cart com-
bination to overturn.
10)
Ventilation
— Slots and openings in the cabinet are provided for ven-
tilation and to ensure reliable operation of the product and to protect it
from overheating, and these openings must not be blocked or covered. The
openings should never be blocked by placing the product on a bed, sofa,
rug, or other similar surface. This product should not be placed in a built-in
installation such as a bookcase or rack unless proper ventilation is provided
or the manufacturer’s instructions have been adhered to.
11) Power Sources
— This product should be operated only from the
type of power source indicated on the marking label. If you are not sure of
the type of power supply to your home, consult your product dealer or local
power company. For products intended to operate from battery power, or
other sources, refer to the operating instructions.
12) Grounding or Polarization
— This product may be equipped with a
polarized alternating-current line plug (a plug having one blade wider than
the other). This plug will fit into the power outlet only one way. This is a
safety feature. If you are unable to insert the plug fully into the outlet, try
reversing the plug. If the plug should still fail to fit, contact your electrician
to replace your obsolete outlet. Do not defeat the safety purpose of the
polarized plug.
13) Power-Cord Protection
— Power-supply cords should be routed so
that they are not likely to be walked on or pinched by items placed upon or
against them, paying particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the product.
14) Outdoor Antenna Grounding
— If an outside antenna or cable
system is connected to the product, be sure the antenna or cable system is
grounded so as to provide some protection against voltage surges and built-
up static charges. Article 810 of the National Electrical Code, ANSI/NFPA
70, provides information with regard to proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an antenna discharge
unit, size of grounding conductors, location of antenna-discharge unit, con-
nection to grounding electrodes, and requirements for the grounding elec-
trode.
"Note to CATV system installer:
This reminder is provided to call the CATV system installer’s attention to
Section 820-40 of the NEC which provides guidelines for proper grounding
and, in particular, specifies that the cable ground shall be connected to the
grounding system of the building, as close to the point of cable entry as
practical.
15) Lightning
— For added protection for this product during a lightning
storm, or when it is left unattended and unused for long periods of time,
unplug it from the wall outlet and disconnect the antenna or cable system.
This will prevent damage to the product due to lightning and power-line
surges.
16) Power Lines
— An outside antenna system should not be located in
the vicinity of overhead power lines or other electric light or power circuits,
or where it can fall into such power lines or circuits. When installing an
outside antenna system, extreme care should be taken to keep from touch-
ing such power lines or circuits as contact with them might be fatal.
17) Overloading
— Do not overload wall outlets, extension cords, or
integral convenience receptacles as this can result in risk of fire or electric
shock.
18) Object and Liquid Entry
— Never push objects of any kind into
this product through openings as they may touch dangerous voltage points
or short-out parts that could result in a fire or electric shock. Never spill
liquid of any kind on the product.
19) Servicing
— Do not attempt to service this product yourself as open-
ing or removing covers may expose you to dangerous voltage or other
hazards. Refer all servicing to qualified service personnel.
20) Damage Requiring Service
— Unplug this product from the wall
outlet and refer servicing to qualified service personnel under the following
conditions:
a)
when the power-supply cord or plug is damaged.
b)
if liquid has been spilled, or objects have fallen into the product.
c)
if the product has been exposed to rain or water.
d)
if the product does not operate normally by following the operating
instructions. Adjust only those controls that are covered by the operating
instructions as an improper adjustment of other controls may result in
damage and will often require extensive work by a qualified technician to
restore the product to its normal operation.
e)
if the product has been dropped or damaged in any way.
f )
when the product exhibits a distinct change in performance – this
indicates a need for service.
21) Replacement Parts
— When replacement parts are required, be
sure the service technician has used replacement parts specified by the
manufacturer or have the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock, or other
hazards.
22) Safety Check
— Upon completion of any service or repairs to this
product, ask the service technician to perform safety checks to determine
that the product is in proper operating condition.
23) Wall or Ceiling Mounting

Reco rding is an a rt a s well as a scien ce. A success-
f 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 DA-
78HR.
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 ana-
log.
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 syn-
chron 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
EMP (
E EM P
), 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 n-
ments, but we suggest th at you keep the environm en-
tal 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 (speak-
ers, 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
1 - Intr oduction to the DA-78H R

9
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 .

1.4.5 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 sup-
plied 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”.

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 electri-
cal groun d, at all times. If it is not, ther e is a possibil-
ity 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 sec-
onds, and swi tch i t on again.

1.4.8 Condensati on

If you use the DA-78HR in a warm place after mo v-
ing 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.
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.
1 - Introductio n to the DA-78HR
10
TASCAM DA-78HR
There are two basic ty pes of Hi8 tape: MP and ME.
Eac h has its ow n particular char acteristics and mer-
its :
MP tap es are manufactured using a d aubed mag-
netic 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 erfor-
mance 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 pack-
aging 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 nu-
f acturers with out notice. The bra nds and mode l nu m-
bers of tapes listed below may not always meet the
specifications required by DTRS sy stems for o pti-
mum performance. TASCAM assumes no responsi-
bility 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 opti-
mu 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 edit-
ing 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 digi-
tally .

T his key turn s the 8 x 2 sub-m ixer ou tput on and off
fro m the re ar pan e l outp ut s. See 7 .4, “Sub -mix er” fo r
details.
W hen the DA-78HR is in shift mode, this key is u sed
to set the level a nd the pan po sitio n of each track in
the sub-mixer image (7.4, “Sub- mixer ”) .

2.4 Track controls

R
REC FUNCTION keys a nd indicators
Thes e eight switches and indicators allow the se tting
and viewing of the record status o n a track -by-track
basis.
When one of these switches is pressed, the appropri-
ate indicator will flas h, the track is “armed” , and
goin g into record mode will start recording on that
track. When rec ording is being car ried out on a track,
the track’s indicator will light steadily.
In ad dition, these keys are also used to selec t tracks
and channels for different operations, including the
input an d out put patchbays, the delay and su b-mixe r
f unc tions. See 7.3, “Tr ac k de lay”, 7.4, “Sub- mi xer
an d 5.3, Input selection for de tails of these
operations.
S
Peak me t ers
Th e se 15-segment peak meters show the input leve l
or the recorded signal level, depending on the moni-
to ring mo de currently in operation ( 6, “Monitoring”).
NOTE
When using digi tal recor ding equipment, there is no
headroom above the 0 dB mark and no tape satura-
tion is possible. Any signal which causes the “OVER”
segment to ligh t will cause audible di s tortion. For this
r eason you should ta ke care not to let recording lev-
els exceed this level.
The ballistics and peak h old times are selectable (s ee
7.8, “Meter mo des”).
T hey may als o be used to prov ide a qui ck visua l
guide to the s tatus of some of the s ettings ( sub- mixer ,
patchbay, etc.). See 4.1.1, “Peak meters” for details.

3 - Connections

This section explains how to connect other equip-
me nt to the DA-78HR. It is not inte nde d as a com-
plete ref erence to the use of the DA-78HR. See the
appropriate sections for f ull details of h ow these con-
nectors are used.
NOTE
S—IMPORTANT
When making connec tions bet ween the DA-78HR and
other equipment, w hether audio or control, both the DA-
78HR and the other equipment m ust be turned
off
, other-
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.

3.1 Audio connections

Other audio equip ment can be connected to the DA-
78HR eith er using analog or digital interfaces.
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 connec-
tions to the DA-78HR are made through 25-pin D-
sub 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 M-
1600 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 availabil-
ity of sui table ready-made cables ( and see 1 2.1.8,
Cables”). However, we recognize that every situa-
tion has its own unique features, and there are occa-
sions 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.
T he pinouts for bo t h t he
ANALOG OUTPU T
and
INPUT
co nnect ors are as follows:
where
G
=ground,
H
=”hot” (+) a n d
C
=”co ld” (–).
The i mpedance of the inp uts i s 20k and that of the
outputs is 10.
3.1.2 U n balance d analog audi o
connections
In add ition to th e balan ced an alog set of co nnection s,
ther e are eight RCA jacks f or input signals and eight
for o utput. These are, of co urse, unbalanced , and the
nominal signal level is –1 0 dBV.
NOTE
On ly c onnect and u se o ne s et of analog input s at a
time. There is no fac ility to swit c h b etween the two
sets of ana log inp ut connectors.

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 sig-
nals 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 sophisti-
cat 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.

.
No te that if the DA-78HR is connected to other
DTRS u nits, the
W ORD SYN C
jacks do not need to
be connected between th e DTRS u nits.
3.2.2 MIDI conn ect ors (IN , O UT and
THR U)
These standard 5-p in DIN MIDI connectors are used
to carry MID I T im e C o de (MTC) and MIDI Mach ine
C ontrol (MMC) informatio n be tween the DA-78HR
and ot he r sui t ably- equipped units (for inst ance,
sequencers capable of being synchronized to MTC,
an d capab le of transmitting MMC commands).
The MI DI parameters are set through the menu
system (see 10, “MIDI control”).
Note the di f ference b etween
MIDI OUT

3.3 Connection to other TASCAM
units
By a “TASCAM unit”, we mean anoth er DA-7 8HR,
a DA-98, DA-88 or a DA-38 unit, or an optional
remote control unit, which may also be connected in
a “chain with multiple DTRS units.

3.3.1 REMOTE IN

This jack on the rear panel can be used to conn ect a
remote control unit such as RC-808 remote control
uni t.
B asic c ontrol can be carried out using this unit, but
more advanced ope rations will not be possible.

3.3.2 Footswitch

A footswitch such as the o pt ional TASCAM RC-30 P
footswi tch can be co nnected to th e
REMO T E PUNCH
IN/OUT
jack on the rear panel.
This footswitch allows hands-free punch-in and
punch-out.
When a track o r track is arm ed, and the unit is in play
mod e, pr essing the foots witch o nce will drop the unit
into re c ord mode , and pressing it again will drop it
back into play m ode.
Th e footswitch , rather than the transport keys, can
als o be used to set punch points, as described in 5.6,
Punch-i n and punch-out”.

4 - Menu interface, et c.

R ead this section to understa nd the basic principles
of the menu operations. These men us are used for
ma king settings wh ich cannot be made directly from
dedi cat ed f ront pa nel ke ys.
In ad dition, this section give s a brief description of
the top-level menu groups as we ll a s th e sub-me nu
item s and the parameter s. This is not a detailed
description of the s e m enus a nd parameter s , but ma y
be consulted for quick reference. See the appropriate
se ctions of the manual for deta ile d in forma tion
regar ding these menu settings.

4.1 The display

The DA-78HR s menus an d their op ti ons are dis -
pla yed using the time counter. Since the d isp la y is
composed of 7-segment LED counters, a special
alphabet is used to show the letters of the alphabet.
The character s on t he DA-78 HR time c ounter are
s hown as in the table below:
When a menu item or a value is given in this manual,
we show it in the following way:
Pk. Hld (
PK HLD
).
Notice also that b ecause there are not m any char acter
pos ition s on the time counter, the E ng lish menu
titles, etc . may be abbrevia te d sometime s.

4.1.1 Pe ak meter s

In ad dition to the time display, the b a rgraph meters
are sometimes used to show a value. For ex ample, in
the stereo sub-mixer settings, the meters ac t as a ba r -
graph d isplay to show the “fader” settings of the
trac k levels.
Typically, the higher the va lue of the parameter, the
more segments of the meter are lit (at minimum val-
ue s, no segments are lit, at maximum values, all seg-
men ts are lit) .
Pr es sing and ho lding
SHIF T
and pressing any
REC
FUNCTION
key in these editing mod es will toggle
th e meter s between data v alue displ ay and the normal
me ter disp lay.

4.2 The SHIFT key

The
SHIFT
key serves two functions: first, to modify
the action of another key when the
SHIFT
key is
presse d an d held wh i le t he other key is pr esse d, and
secondly, to enter “shift m ode”. These two are
expl ained below.

4.2.1 Shif t ed ke ys

Some keys of the DA-78HR perform two functions,
l abels associated with the key. For instance, th e
LOC
1
(locate to memory position 1) key, has the alterna-
t ive “shifted ” function marked as
MEMO 1
(st ore the
cu r ren t time into me mor y locatio n 1).
When th e
SHIFT
key i s pre s s ed and hel d dow n, and
one of these keys, as described in the relevant part of
this m a nu al, is pressed, the shifted function will be
performed.
The two keys can then be released in either order
(eithe r the
SHIFT
ke y or the other k ey c an be rel eased
firs t).

4.2.2 Shif t mode

By contrast, pressing the
SHIFT
ke y a l on e a n d re le as-
ing it will place the u nit int o “shift mode”. The
SHIFT
indicat or flashes to s how this.
Pressing any of the two-function keys while th e unit
is in sh ift mode will automatica lly enter the shifted
function.
W hile th e unit is in shift mode, pressing the
SHIFT
ke y once again will turn the indicator off and exit
SHIFT
mode.
No te, however, that pressing and holdin g the
SHIFT
key and pressing another k ey to access the shifted
func tion of that ke y will n ot affect the current shift
mode.

4.3 Men us and sub-menus

W hen the unit is in shift mode, th e
REPEAT
(
MENU
)
key is the “gateway” to the menus. This key is used
to sh ow the top level gr oups of the menu tree:
When the
MENU
key is presse d, one of this grou p
na mes is displayed on the screen and the unit ente rs
menu mo de. W hen the
MEN U
key is presse d again,
the next men u group na me in this list above is shown
(the list is “circular”, i.e . th e first gr oup name follows
the last in the list).
Pr es si n g a nd holding dow n the
SHIF T
key and press -
ing th e
MENU
key goe s to the previous menu gr oup,
followin g th e order describ ed ab ove. Once again, the
list is regard ed as “circular”.
Note that the titles of these to p-level menu groups a re
all follo wed by two dashe s (
--), sho wing tha t there
are su bmenu s “un der th is lev el.

4.3.1 Exiting menu mode

To ex it men u mode, either:
turn of f t he sh i ft mo de (p r es s th e
SHIF T
ke y so th a t
its indicator is no longer flashing)
or
e nter ano ther shifted func tion (except for the
shif ted
MENU
or
SUB MENU
fun cti ons)

4.3.2 Sub-menus

When a menu is displayed, pr essing the sh ifted
CHASE
ke y (
SUB MENU
) b ri ngs up t he sub-me nu
items associated with that particular top-level menu
group.
There are two dif ferent way s of displaying sub- menu
items:
one is that the name of the pa r a meter to be
adjus ted, and the current v alu e o f the parameter ar e
displ ayed together.
the other wa y is to th at th e nam e of th e p aram eter is
displayed for one seco nd, a nd the display the n
changes to the current value of the parameter (th is
is when the par ameter name and/or th e value are
too long to be displayed together).
Pressing the
SUB MENU
key cycles through the list
of su b-menu items in a top-level menu group (th e list
is regarded as circular).
Pressing and holding the
SHIFT
key and pressing the
SUB MENU
key cycles through the s ub-m enu item s
in the reverse order.

4.3.3 Adjusting parameter values

In menu mode, the
AU TO MO N
and the
ALL INPUT
keys pe rfor m th e functi on of up and d own keys (
and ) and th ey are used to change the values of
parameters in the sub-menu items.
As soon as the valu e of the parameter is changed on
the dis play, the p a rame te r itself is changed (i.e. there
is n o need to confirm changes with an ENTER key or
the equivalent).
If one of these keys is pr essed and held down fo r ha lf
a second, the key changes to a “repeat m ode. If the
key is held down for one second, the rep eat mo de
changes to a “fast repeat” mode, and the value of th e
p arameter chan ges fa st er.
4 .3.4 Resetting parameters to d efault
values
To reset a para meter value to the def ault value, pres s
and hold down the key and immediately after-
w ard s, pr ess th e key, or vice versa.

4.3.5 “Le f t and right” keys

W hen editing time values, etc. it is useful to be able
to edit one particular element (i.e. hours, minutes,
s e conds or frames) of the time value.
The “cursor ” is indicated b y a flashing d ot follo wing
the “field” currently being edited.
There are no dedicated left and right cursor keys.
Instead, when th e unit is in men u mode, press ing and
hold ing the
SHIFT
key and pres sing the key will
have the effect of a left cursor key.
L ikew ise, pr essi ng a nd holdi ng the
SHIFT
key an d
pres sing the ke y will have the effec t of a right c ur-
sor key.
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
percentage Sub-fram es perce nt age (w ith inc r e-
ment of wh ole time value) Sub-frames sampl e s
Sub - frames samples (with increment of whole time
value) Hours , etc.
T he ri ght cursor key” (
SHIFT
+ ) moves forward
through th e list, and the right “cursor” key (
SHIFT
+
) moves backward.
The sub-fra me dis plays (in italics abov e) a re
explained in the section below (4.3 .6, Sub-frame
values”).

4.3.6 Sub- f rame values

There are two ways of r epresenting sub-fram e val-
ues: 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 sam-
plin 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 (
SF
), followed by
either the 2-digit rep resenta tion of the percentage
subframe value
SF ;;
, or the 4-digit representation
of the sample value
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.
