7 – Making settings on the
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

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

key will select tracks 41-48. Subsequent

presses of the

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

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.
