Tascam RC-898 - Manual (Page 33)

Section 6.5 - Location operations
6-3
The time mode selected here is the reference time
mode for punch operations, location operations,
etc.
1) From menu group 3, move the cursor to
TimeMode and press SELECT :
In the above screen, all machines are referenced to
the ABS time.
2) Use the UP and DOWN keys to select between
ABS and TC settings.
6.5 Location operations
Location transport operations on the RC-898 are
mainly controlled using the
LOC key [41]. This
key, which has no equivalent on the DTRS units,
allows the instant location of the tape to the value
shown in the
LOCATE TIME/VALUE display.
However, it is also possible to set a locate pre-roll
time, and if this is set to a non-zero value, locating
to a position will move the tape to the time shown
in the display, minus the pre-roll value.
For example, if the pre-roll time is set to 5 sec-
onds, and the time shown in the
LOCATE TIME/
VALUE display is 01:23:03:02 , when the
LOC key is pressed, the tape will locate to
01:22:58:02 . This allows time for cueing,
slave unit lock-up, etc.
6.5.1 Setting the location pre-roll value
To set the pre-roll value which will be used by
location operations:
1) From menu group 0, move the cursor to
Loc Pre , and press SELECT :
2) Use the LEFT and RIGHT keys to move
between the min and sec fields, and set the
values using the
UP and DOWN keys.
It is also possible to use the numeric keypad here.
The “hours” and “frames” digits of the value
shown in the
LOCATE TIME/VALUE display will
be ignored, and only the “minutes” and “seconds”
used.
The maximum value that may be set here is
59min59sec , and the minimum value is
00min00sec . It is not possible to have a
negative pre-roll time.
6.5.2 Auto play
When the DTRS unit reaches the location point, it
will normally go into stop mode.
However, if the AUTO PLAY indicator [33] is on,
the unit will automatically start playing when the
location point is reached.
6.5.3 “Instant” location
If you are playing back or recording, and you wish
to mark a point for later one-time location:
1) Press the CAPTURE key [29] at the point
where you wish to return.
2) At any point following the capture, press the
LOC key to return to the location point that has
just been captured.
It is not necessary to stop the tape before pressing
LOC . Location can be performed while the unit’s
transport is in any mode, including fast forward
and rewind.
You can now “fine-tune” this time value (see 6.5.5,
“Editing a location”). This location point may also
be stored in a location memory (see 6.5.6, “Storing

NOTES
Note that these settings show the way in which the position
on the DTRS unit is shown on the
TAPE TIME display and
may also be used to control the chase mode of the DTRS
units as described in 8.1.8, “Chasing to external timecode”.
NOTE
In the following explanations, in the interests of clarity and
brevity, we will refer to the units locating to the location
time. This should always be assumed to be the location time
minus the location offset, unless specifically mentioned
otherwise.

NOTES
The values set here apply to the RC-898 location functions,
and are not affect settings made on the DTRS units con-
nected to the RC-898.
The values set here do not apply to the auto-punch operation
pre-roll time, which is set using a separate menu (see 6.7.5,
“Setting pre-roll and post-roll times”).
