Section 8 – Advanced operations
8-6 – 1.00 – 06/97
ative to normal speed): 0.25, 0.5, 1.0, 2.0, 4.0, 8.0.
The 1.0 speed is only available when shuttling in
the forward direction.
Shuttle operations are only possible when the
SHUTTLE
indicator is lit (press the
SHUTTLE
switch).
8.6.1 Shuttle monitoring
This is also covered in 7.1.3, “Shuttle monitor-
ing”.
The default behavior of the DA-98 is that when
shuttling the tape, you can choose whether to
monitor off-tape or source when shuttling, using
the tracks’
INPUT MONITOR
switches.
When
AUTO MON
[19] is on
,
the monitoring of
any armed tracks will be off-tape, unless the
SHTL
MON
[20] is on, in which case, the monitoring of
armed tracks will be source input. The monitoring
of all other (unarmed) tracks can still be switched
on a track-by-track basis using the tracks’
INPUT
MONITOR
switches.
The
SHTL MON
key is only enabled when
AUTO
MON
is on. When
AUTO MON
is off, it has no
effect.
8.6.2 Shuttle muting
As explained above, shuttling the tape will usually
allow off-tape monitoring. However, there may be
times when you will want to mute all off-tape sig-
nals when shuttling.
1) Enter menu group 2, move the cursor to
Shtl
Mute and press
ENTER
:
2) Use the
UP
and
DOWN
keys to set the shuttle
mute on or off .
8.7 Reference levels
The value of reference level (for analog inputs and
outputs) on the DA-98 can be selected from
among three standard values: TASCAM, SMPTE
and European reference levels, depending on the
application. The meanings of these three levels
are:
To set the reference level, perform the following
steps:
1) Enter menu group 2, move the cursor to
Ref
Level , and press ENTER:
2) Use the
UP
and
DOWN
keys to select between
the following: -16dB FS, -18dB FS and
-20dB
FS.
NOTE
If the
SHUTTLE knob remains untouched at the
center position for 10 seconds, the shuttle mode is dis-
abled, and the indicator goes off.
NOTE
When monitoring in shuttle mode, the monitor signal is
attenuated by 12 dB (to avoid possible damage to ears
and speakers ).
