Kolpak DA-98 Manual De Usuario

Section 8 – Advanced operations

8-4 – 1.00 – 06/97

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

Delay

. 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

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

all

(

all

can be selected using function keys 9 or 10).

3) By moving the cursor to the bottom right

parameter (shown here as “

Sample

”), and

using the

and

DOWN

keys, you can display

and set the track delay in either samples or
milliseconds (

msec

4) Move the cursor to the central number. The

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

key and then pressing

the

DOWN

key. If “

all

” 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.
