DTRS units
This section covers the operations which relate to
the DTRS units, other than those specifically
related to timecode.
7.1 Track operations
The following series of operations relate to indi-
vidual tracks of the DTRS units connected to the
RC-898.
7.1.1 Track delay
When recording or playing back, tracks on a
DTRS unit may be delayed by up to 7200 sam-
ples, or advanced relative to other tracks up to a
value of 200 samples.
This is possible due to the design of the recording
and monitoring heads in the DTRS mechanism.
1) From menu group 0, move the cursor to
Delay and press SELECT :
2) Use either the UP key or the numeric keypad to
change the track number by individual track.
3) When track 1 is shown, you can press the
DOWN key to select the eight tracks of the first
DTRS unit. Continue pressing the DOWN key
to select the tracks in groups of eight for the
subsequent DTRS units (i.e.
9-16 , 17-24 ,
etc.):
Any changes to the delay time made when a group
fo eight tracks is shown will affect the delay time
of all tracks on the unit. This allows you to set the
delay times for different DTRS units in the chain
easily (to slip times, etc.).
When track 48 is shown on the display, pressing
the
UP key will select tracks 41-48. Subsequent
presses of the UP key will select the other DTRS
units in order, working towards the head of the
chain.
4) Move the cursor to the numerical value field
and use the UP and DOWN keys or the numeric
keypad to enter a value.
The +/– key of the numeric keypad allows you to
enter negative values here, as shown by the period
after the last digit in the
LOCATE TIME/VALUE
display.
5) If you prefer to work in sample values, rather
than milliseconds, move the cursor to the
msec field and change it to sample with
the DOWN key.
The delay value is now converted to samples at the
current sampling frequency, and is up to 4 digits
long.
7.1.2 Track copying
This operation allows the assignment of
inputs (either digital or analog) on a track-by-track
basis. This facility is not available on DA-88 units.
This means that a patchbay is not required to
reroute input signals
As well as external inputs, tracks which have
already been recorded can be used as recording
sources. This feature therefore allows tracks to be
copied within a unit.
It does not allow routing or copying of tracks
between machines, nor does it allow the combina-
tion (“ping-pong” of tracks). For these operations,
an external patching or mixing system is required.
For further details of this feature, consult section
8.11 of the DA-98 manual, or 4-7 of the DA-38
manual.
1) From menu group 0, move the cursor to Trk

NOTE
The track number here may be set from 01 to 48. Tracks
refer only to DTRS units, not to any other equipment which
may be using the
REC FUNCTION switches of tracks 41
through 46.
