11
[5] RECORD MODE switch
Use this switch to choose between
HR(24BIT)
and
STANDARD
. The
HR(24BIT)
setting records with
24 bits of resolution. The
STANDARD
setting will
record at 16 bits of resolution.
Operating Tip
It is not possible to record a tape partly in
HR(24BIT)
mode and partly in
STANDARD
mode (an error message will appear (see
6.5.1, "Warning messages"). If a tape has
been recorded in one mode, and it is required
to re-record it in another mode, the tape must
be rewound to the start, and the new record-
ing mode selected using this switch. The
RECORD
key must be pressed and held, and
the
PAUSE
key pressed. Press and hold the
RECORD
key once more, and press the
PAUSE
key. The recording can now take
place in the selected mode.
Note that it is not possible to enter input mon-
itor mode (see
RECORD KEY [17]
) if this
RECORD MODE
switch is set to one record-
ing mode and the tape currently loaded in the
tape deck is has previously been recorded in
another. This helps to avoid the two modes
being mixed on one tape.
NOTES
When recording with the switch set to the
HR(24BIT)
position, the tape moves at twice
the normal speed. A tape which is labeled as
a 90-minute tape will therefore provide 45
minutes of recording time. The tape time that
is displayed in the
HR(24BIT)
mode is either
the ABS subcode, or actual elapsed time, as
set in 3.11, "HR time display".
If a tape has been recorded in
HR(24BIT)
mode, it cannot be replayed on a DAT tape
deck that does not support this mode.
When recording digitally from a CD or other
material which contains fewer than 24 bits of
resolution and this switch is set to
HR(24BIT)
,
the lower “extra” bits will be unused.
No setting is necessary to select the bit resolution for
playback— the tape deck recognizes the recording
mode in which the tape was recorded and adjusts
accordingly.
When the tape deck is in record ready mode, as men-
tioned above, turning the
DATA
dial
[20]
allows the
selection of a program number other than
01
,
meaning that this recording will start at the selected
number, and subsequent programs will be written
with numbers automatically incremented from this
selected value.
NOTE
Valid program numbers are from 01 to 99. If
the above procedure is used to select a pro-
gam number at the high end of the range, and
the automatic increment procedure takes the
number above 99, the number will “wrap” to
00. The number 00 can cause problems when
searching and locating, and this should be
remembered when setting program numbers.
[6] Fs switch
Use this switch to select the sampling frequency
(44.1 or 48 kHz) when making analog recordings.
When making digital recordings, the sampling fre-
quency is automatically detected.
When playing back tapes that have already been
recorded, this switch has no effect. The sampling fre-
quency of a recorded tape is fixed, and cannot be
changed.
[7] INPUT selector switch
The left (
UNBAL
) and center (
BAL
) positions of
this switch allow the selection between the unbal-
anced RCA jacks or the balanced XLR jacks
respectively.
The right (
DIGITAL
) position allows the selection of
the digital input jacks.
[8] DIGITAL INPUT selector switch
When the
INPUT
switch
[7]
is set to the
DIGITAL
position, this switch is used to choose between the
RCA
COAXIAL
and the XLR
AES/EBU
digital
audio input sources.
NOTE
Despite the name of the switch setting and
the connectors (AES/EBU), the XLR connec-
tors are capable of receiving SPDIF format
input, and the RCA COAXIAL connectors are
capable of receiving AES/EBU format. The
tape deck will automatically detect the input
format and adjust itself accordingly.
