If the tape is rewinding to the first location point
when the
REPEAT
key is pressed, it will stop.
8.3 Track delay
The DA-98 allows you to delay tracks relative to
the other tracks, either when recording or playing
back. You can use this function for post-produc-
tion “slip”, compensate for delays caused by
external processing equipment, allow for propaga-
tion delay in multi-microphone sessions or add
special effects.
The track delay can be set from –200 samples to
+7200 samples. A negative number means that the
track on which the “delay” setting is made is
advanced in time relative to the other tracks. How-
ever, this does not mean that the DA-98 includes a
time machine! Since the monitoring head is a “vir-
tual” head, made of a composite of delayed off-
tape and input source signals, the “position” of the
recording head can be adjusted in both directions.
The track delay, expressed in seconds, is between
–4 to +150 milliseconds. At a typical sound propa-
gation rate, the maximum value corresponds to
about 50 meters (about 160 feet) of distance.
8.3.1 To set the track delay:
1) Select menu group 0, and move the cursor to
. Press the
ENTER
key:
2) To select the track whose delay time you want
to change, move the cursor to the number at
the bottom left of the screen and use the
UP
and
DOWN
keys to select the track.
If the function keys are in number entry mode (see
5.2.2, “Using the function keys as number keys”),
you can use keys
F 1
through
F 8
to select tracks 1
through 8 directly.
You can select tracks
through or (
can be selected using function keys 9 or 10).
3) By moving the cursor to the bottom right
parameter (shown here as “
”), and
using the
UP
and
DOWN
keys, you can display
and set the track delay in either samples or
milliseconds (
).
4) Move the cursor to the central number. The
UP
and
DOWN
keys will change the delay value for
the selected track(s).
Remember that you can reset the value to zero by
pressing and holding the
UP
key and then pressing
the
DOWN
key. If “ ” has been selected for the
track, then all track delays will be reset to zero.
You can also use the function keys to enter the
value directly, as described in 5.2.2, “Using the
function keys as number keys”.
8.4 Crossfade times
As we mentioned earlier (see 6.6, “Punch-in and
punch-out”), digital punch recording requires that
the original and new signal be crossfaded over a
short period of time.
The factory default crossfade time for the DA-98
is 10 ms, and this can be adjusted in 10 millisec-
ond steps to a maximum of 200 ms.
For the most part, 10ms is an adequate value and
will produce seamless punches, but there may be
times (matching reverb settings, etc.) when a
longer crossfade is required.
NOTES
• The two location points must be at least 5 seconds apart
for the repeat facility to be operational.
• If you have only set one location point, the repeat will
be between “00:00:00:00” and the location point.
• Pressing any transport control while repeat play is in
progress will stop the replay, but will not cancel the
repeat mode. To restart the repeat playback, locate to
either location point, and while the tape is winding,
press
PLAY
. Alternatively, press
PLAY
while the
tape is before the second location point.
NOTE
When any track is set to be delayed, the
DELAY
indica-
tor by the tape counter [2] will light.
