DS-D98 recorder
TASCAM DS-D98 -
9
Shuttle mode
In PCM mode, shuttle operations are possible (7.6,
“Shuttle operations”), but when shuttling, no sound is
output.
The concept of shuttle muting (7.6.2, “Shuttle mut-
ing”) therefore has no meaning in DSD mode.
Board versions
When the DSD board is fitted and the input and out-
put board firmware version is checked using the
menu system (menu group D), the input and output
board information is displayed in an identical way on
the two screens.
Error messages
Most error messages displayed in DSD mode are
identical to those displayed in PCM mode, except for
the following:
If the board PLL clock becomes unlocked, either on
the input or output stage,
Input Slot
Unlocked
will always be shown.
Note that in PCM mode, if an attempt is made to
select the
SLOT
option as the clock source with the
48kHz family of sampling frequencies, an error mes-
sage is displayed:
no clock
, as the DSD slot
card cannot be used with these sampling frequencies.
Analog reference levels
The DS-D98 is capable of accepting and outputting
analog signals at one of three reference levels:
As the unit is shipped, it confirms to the TASCAM
standard. If this is to be changed, this must be done
by changing jumpers on the DSD board.
Both input and output reference levels should be set
together. It is not possible to set only the input or
only the output reference level.
WARNING
b
Regarding installation and configuration details, con-
sult your nearest TASCAM dealer.
These instructions are for use by authorized service per-
sonnel. Fitting and removing slot boards are not user
operations and such operations carried out by unautho-
rized personnel will void the warranty.
A cross-head (Phillips) screwdriver and a flat anti-
static surface on which to lay the boards while you
are working will be necessary, as well as sufficient
space to work (if the DS-D98 is mounted in a rack, it
will probably have to be removed from the rack in
order to fit the boards).
There are four jumpers to be set on the board:
These jumpers have the following meaning (where
✔
is closed and
✘
is open).
