tape from the beginning, you should wait until the
end of the tape before rewinding and ejecting it.

5.1.3 Arming tracks

The tracks of the DTRS units are armed using the

REC FUNCTION

keys with their indicators.

These keys and indicators only work for tracks of
units that are actually connected.

Armed tracks, i.e. those which are ready for
recording, are shown by their indicators flashing.

Tracks which are actually recording are shown by
their indicators being steadily lit.

When a DA-88 or DA-38 track is recording, the

INPUT MONITOR

indicator will light, showing

that the monitoring for the tracks is from the input
source, rather than being off-tape. The

INPUT

MONITOR

keys are not operational with a DA-88

or DA-38 unit.

When operating a DA-98 unit, the

INPUT MONI-

TOR

keys are operational, and can be used to

change between off-tape and source monitoring.

5.1.4 ALL SAFE

The

ALL SAFE

key [3] prevents accidental arm-

ing of tracks. When lit, all

REC FUNCTION

indi-

cators go out, and the keys of both the RC-898 and
the DTRS unit or units (see 7.2.2, “Key Mode”
below) are locked (pressing them will not arm
tracks).

When the

ALL SAFE

key is pressed to turn off

the safe operation, the arming status of all tracks
will return to what it was before the

ALL SAFE

key was pressed.

5.1.5 Transport controls

The RC-898 shares a common interface with all
DTRS units with regard to transport functions
(including entering end exiting record mode).
Consult the relevant portions of the DTRS unit
manual if you are unsure of the way in which
transport operations are carried out.

One exception to this is the

LOC

key [41] which

does not appear on the front panel of DTRS units.
It is used to locate the tape to the value shown on
the

LOCATE TIME/VALUE

display [15]. For full

details of how this key is used and the location
facilities available from the RC-898, see 6, “Loca-
tion functions”.

5.1.6 Shuttle mode

The RC-898 incorporates a jog dial and shuttle
wheel to allow precise positioning of the tape in
the DTRS units.

When the

DATA INC/DEC

indicator [27] is not

lit, moving either of these controls will control the
selected unit(s) appropriately.

The indicators will go out 10 seconds after the
jog/shuttle controls are last used.

The shuttle wheel allows forward motion at the
following speeds (relative to normal speed): 8 x,
4 x, 2 x, 1 x, 1/2, 1/4. The same speeds, except for
1 x, are available in reverse mode. The further the
shuttle wheel is turned away from the center posi-
tion in either the clockwise or counterclockwise
direction, the faster the tape will be moved.

The jog dial allows very precise positioning of the
tape to frame accuracy.

Monitoring during shuttling is explained below
(see 5.2.3, “Shuttle monitoring”).

5.2 Monitoring

The monitoring of off-tape and input source sig-
nals is complex, and varies a little between the
DA-88 and DA-38 units, and the DA-98 units, due
to the latter being provided with track-by-track
switching facilities between source and off-tape
monitoring, as well as the confidence mode
method of off-tape monitoring while recording
(see 7.2.12, “Confidence mode”).

NOTES

The display shows a negative ABS time for a few seconds at
the beginning of the tape. While a negative time is shown,
no audio can be recorded on the tape.

We suggest that you leave a blank header of at least 30 sec-
onds at the beginning of the tape. This can be marked as a
virtual “zero point” if you like (see 6.3, “Setting a relative
time reference”)
.

NOTE

Before recording, you should make sure that either digital or
analog inputs, as required, have been selected (see 7.2.9,
“Input selection”)
and the appropriate clock settings have
been made (see 7.2.6, “Clock selection”).

NOTE

When the currently-selected unit is recording, the jog and
shuttle controls are disabled (this prevents accidental inter-
ruption of a take).
