6 – Basic operations
This section explains some of the basic operations
using the DA-98. Section 8, “Advanced opera-
tions” describes more advanced operations.
Most operations on a DA-98 are similar to those
on a traditional analog multitrack recorder, but we
suggest that you read this section and the next to
learn about the features of the DA-98.
6.1 Formatting a tape
Before you use a tape in the DA-98, you must first
format it. This marks internal synchronization pat-
terns for the servo to follow on subsequent passes
through the tape as well as the subcode data
(ABS). No audio data is normally recorded during
a formatting operation (but see below).
While formatting is proceeding, you cannot per-
form any other transport operation except stop-
ping the tape.
You cannot change the sampling rate while for-
matting is in progress.
1) Switch on the DA-98 and load a tape into the
tape loading slot [3]. As the tape is loaded and
threaded, the tape counters will show
.
For details of tapes that you can use in the DA-98,
see 1.5, “Recommended tapes”.
2) Press REW [32] to take the tape to the
beginning. When the beginning of the tape is
reached, the tape counter will show
(“beginning of tape”).
3) Press the
FORMAT/Fs
switch [6]. The
FORMAT
indicator will start blinking. Press the
FORMAT/
Fs
switch again within 5 seconds. The
FORMAT
indicator will then light steadily.
If you do not press the
FORMAT/Fs
switch twice
within 5 seconds, the indicator will go out. This is
a feature designed to stop you formatting a tape
accidentally.
4) Now use the
FORMAT/Fs
switch to select the
sampling frequency (either 44.1kHz or 48kHz).
The sampling frequency that you select depends
on the eventual use for the recording. For audio
work, selecting 44.1kHz will allow you to produce
CD master tapes with no frequency conversion.
5) To start formatting the tape, hold down the
RECORD
key [36] and press the
PLAY
key [35].
6) The tape will format to the end, and then
rewind automatically, stopping at the
position.
You are now able to use the tape for recording.
It is possible to format tapes on a number of
DTRS units simultaneously. For details, see 9.4.1,
“Synchronized formatting”.
6.1.1 Aborting the format process
To abort the process before formatting actually
takes place (i.e. you have pressed the
FORMAT/Fs
switch twice in error), press the
CLEAR
key [11].
The
FORMAT
indicator will go out.
As explained earlier, the only transport operation
you can perform once formatting has started is to
stop the tape.
NOTE
If you do press the
FORMAT/Fs
switch twice so
that
the indicator lights steadily and you then change your
mind about formatting the tape, you can use the
CLEAR
key [11] to
cancel the operation.
NOTE
If a digital signal is received at the
DIGITAL I/O
jack
[45] as selected and shown by the
DIGITAL IN
switch
and indicator [15], the DA-98’s recording and playback
sampling frequency is automatically determined by the
sampling frequency of the input signal and you cannot
change it.
NOTE
The tape counter may show a negative ABS time for a
short while at the start of the formatting process. While
it is displaying a negative value, no audio recording can
take place.
