Use the ▲ and ▼ keys to change the value
(maximum +6.0%, minimum –6.0%, in 0.1%
steps).
Reset the value to 0.00% by pressing and hold-
ing either of the ▲ or ▼ keys, and pressing the
other.
3
Press the
SHIFT
key to turn off the setting
mode. The
VARI SPEED
indicator will continue
to be lit, showing that varispeed is currently
en abled.
4
Turn off varispeed (when the
VARI SPEED
indicator is lit) by pressing the
VARI SPEED
key to turn the indicator off.
NOTE
The
VARI SPEED
indicator will light whenever the
varispeed is enabled, even if the speed is set to
0.0%.
Playback and recording will now take place at the
new speed.
7.7 Shuttle operations
The shuttle key, indicator and knob are used to simu-
late the “rock and roll” location method on open-reel
tape decks, allowing you to locate a point on tape
through audible cues.
As the knob is moved from the center detented posi-
tion, the shuttle speed becomes higher.
The variation in speed is not continuous; but as you
turn the knob from the center position, the shuttle
speed changes, following these values (relative to
normal speed): 0.25, 0.5, 1.0, 2.0, 4.0, 8.0. The 1.0
speed is only available when shuttling in the forward
direction.
Shuttle operations are only possible when the
SHUT-
TLE
indicator is lit (press the
SHUTTLE
switch).
If the
SHUTTLE
knob remains untouched at the
center
position for 10 seconds, the shuttle mode is disabled,
and the indicator goes off.
7.7.1 Shuttle monitoring
This is also covered in 6.3, “Shuttle monitor”. The
default behavior of the DA-78HR is that when shut-
tling the tape, you monitor off the recorded tape.
NOTE
When monitoring in shuttle mode, the monitor signal
is attenuated by 12 dB (to avoid possible damage to
ears and speakers ).
When
AUTO MON
is on
,
the monitoring of any
armed tracks will be off-tape, unless the
SHTL MON
is on, in which case, the monitoring of armed tracks
will be source input. The monitoring of all other
(unarmed) tracks can still be switched on a track-by-
track basis using the tracks’
INPUT MONITOR
switches.
The
SHTL MON
key is only enabled when
AUTO
MON
is on. When
AUTO MON
is off, it has no effect.
7.7.2 Shuttle muting
As explained above, shuttling the tape will usually
allow off-tape monitoring. However, t here may be
times when you will want to mute all off-tape signals
when shuttling. This procedure is described in 6.4,
“Shuttle muting”.
7.8 Meter modes
The DA-78HR peak bargraph meters can be custom-
ized to suit your working preferences. Both the peak
hold time and the “ballistics” of the meters can be
adjusted.
7.8. 1 Peak h old time
1
Press the
SHIFT
key so that the
SHIFT
indicator
is flashing, and press the
MENU
key until the
display shows
SYSTEM-- (
SYSTEM--
).
2
Press the
SUB MENU
key until the display
shows
PK. H. LD. ;; (
PK H LD xx—
peak hold)
with the current value for this setting.
3
Use the ▲ and ▼ keys to change the value
between
0
and
9
seconds or
CNT
(
CNT
—con-
tinue—which will permanently display the
maximum peak signal level. This can be useful
if you are doing a “dry run” rehearsal, but you
cannot keep your eyes on the meters all the
time that the rehearsal is going on).
To turn off the peak hold display if
CNT
has
been set, change the peak hold value to
0 sec-
onds and the meter segments will “drop back”.
7.8. 2 Meter balli stics
Use a similar process to change the “fall-back” bal-
listics of the peak meters. You cannot change the rise
time of the meters, which are fixed with peak meter
characteristics.
