TASCAM DA-78HR
2.1 General controls and
indicators
1 Power switch
Turns the power to the DA-78HR on and off. When
the DA-78HR is turned off, settings will be retained
in memory.
2 Tape loading slot and EJECT key
Only use Hi8 ME or MP tapes as specified in 1.5,
“Recommended tapes”. The DA-78HR will automat-
ically eject all other tapes.
NOTE
—I MP OR TAN T
Do not use a tape which has been used for recording
video. Always use either new tapes or tapes which
have been used in a DTRS recorder.
The EJECT key ejects any loaded cassette. A cassette
can only be ejected when the transport is stopped.
3 FORMAT/Fs key
The FORMAT/Fs key controls the formatting of tapes
and allows selection of the sampling frequency used
for recording (see 5.1, “Formatting a tape” for full
details). The current sampling frequency is shown on
the status indicators
6
.
4 HR MODE key
This key allows the selection of the recording resolu-
tion (16-bit or high-resolution 24-bit). See 5.1, “For-
matting a tape” for details.
The appropriate indicator
6
will light if the HR
mode is selected.
5 CLOCK key
This is used to select the word sync source for the
DA-78HR (either internal,
WORD or DIGITAL IN , as
shown on the indicator 6 ).
6 Status indicators
The status indicators show the current status of vari-
ous DA-78HR functions. The legends of these indi-
cators are abbreviated for reasons of space. Here is a
list of their full meanings, together with the pages on
which the functions are more fully described:
7 Tape counter
The tape counter gives the current tape time in hours,
minutes, seconds and frames.
It is also used to display menus, sub-menus and the
values of the parameters of the unit, as well as pro-
viding information on the current status of the unit.
8 PB CONDITION indicator
There is one more indicator: PB CONDITION , which
lights if there are many errors when reading or
recording the tape. It also flashes when the block
error rate is being checked (11.1.2, “Checking error
rates”).
If this lights frequently, the block error rate can be
checked and the heads cleaned (11.1, “Head and
transport cleaning”).
2.2 Tape transport keys and
controls
9 REW key
Rewinds the tape at high speed.
If this key is pressed during recording, recording will
stop and the tape will rewind.
A F FWD key
Winds the tape forward at high speed.
If this key is pressed during recording, recording will
stop and the tape will wind forward.
NOTE
When either REW or F FWD is pressed for the first
time after powering up, or loading a tape, the unit first
configures itself for the reel hub diameter of the tape
in use, during which the tape advances at low
speeds. This takes several seconds. Thereafter, the

When both of these are lit, the
DA-78HR is using internal word
sync, and when neither is lit,
word sync is being received

lit, the word sync is being
received through the appropri-
ate connector (digital audio
(
COAXIAL ) or word sync).
