Section 7.2 - Unit-related functions
7-3
1) From menu group F, move the cursor to Key
Mode , and press SELECT :
2) Use the UP or DOWN key to select between
All and Individual .
If you select Individual , only that unit cur-
rently selected for control (see 5.1.1, “Selecting
the unit to which operations refer”) will be con-
trolled by the three keys mentioned above. If you
select
All , then all DTRS units connected will
respond to the commands of the ALL SAFE , ALL
INPUT and AUTO MON keys.
7.2.3 Chasing with an offset
It is not always required that the DTRS units are in
perfect synchronization with each other.
For instance, it may be that three DTRS units are
being used for video post-production purposes.
The dialog and Foley tracks of a project have been
recorded on one DTRS tape (up to eight tracks),
and the backing music has been recorded on two
more tapes (16 tracks). Obviously, the units
replaying the two music tapes should be synchro-
nized to each other, but the music may need to be
“slipped” relative to the dialog and Foley unit
(which is, in turn, synchronized to the timecode
on the video, as described in 8.1.8, “Chasing to
external timecode”).
Once the dialog and Foley is synchronized to the
video timecode, “slipping” the two music units is
accomplished in the following way:
1) From menu group 3, move the cursor to Mcn
Offset and press SELECT :
2) Choose the first machine which will take the
chase offset (in the illustration above, we show
machine 2) by using the
SHIFT and UP ( NEXT )
keys.
3) Use the numeric keypad to enter an offset value
which is shown on the LOCATE TIME/VALUE
display. The +/- key of the numeric keypad is
used to change between positive and negative
values.
The offset value may be
±
2 hours relative to the
master time.
You can also use the cursor keys to enter a value
directly on the display screen.
The Auto Offset function described below can also
be used to set the offset.
4) Transfer the value to the display screen by
pressing and holding down the SHIFT key [23]
and pressing the ENTER/LOAD key [20].
5) Use the SHIFT and UP ( NEXT ) keys to select
any other units which will chase with an offset.
When the master DTRS unit plays, the slave units
should now chase at the offset value you have set
up.
If an offset value is set on any unit or units, and
the Time Mode is set to ABS, the
OFFSET indi-
cator [10] will light.
If you need to “fine-tune” these values, you can
use the
UP and DOWN keys to adjust the value of
the offset while monitoring the playback of the
units.
If adjustment finer than a frame is required, it is
suggested that you use the Track Delay function
(see 7.1.1, “Track delay”).
7.2.4 Auto Offset function
In addition to the manual offset entry, it is also
possible to set an offset automatically by follow-
ing the procedure below:
1) From menu group 3, move the cursor to
McnOffset and press SELECT .
K e y M o d e
A l l
M a c h i n e O f f s e t
M a c h i n e 2
+ 0 0 : 0 0 : 0 0 : 0 0 A B S
NOTE
There is an “invisible” field immediately to the right of the
frames field. If you place the cursor there and increment or
decrement the value, you can change the time as a whole (as
the frame field passes its maximum value, the seconds field
will increment).
