Press the
CHASE
key on all of the sl ave DTRS
units. The indicator will flash.
4
Press
FORMAT/Fs
twice within five seconds, on
each of the DTRS units (master and all slaves)
so al l machines are ready to start formatting.
If you press the
CLEAR
key while the
FORMAT
indicator is lit steadily, you will cancel the for-
mat operation.

Select the same sampling rate (48 kHz or
44.1 kHz) on each DTRS unit.
Any slave DTRS unit which has a different
sampling frequency selected from that selected
on the master will display an error message.

RECORD
on
the master. All slave units’
CHASE
indicators
will light steadily, and the tapes will start to be
formatted in synchronization.
8.5.1 Recording while formatting
As with a single-machine format (5.1.4, “Recording
while formatting”), it is possible to record while for-
matting on multiple machines.
You may want to use this feature when making a live
multi-machine recording, and there has not been time
to format all the tapes in advance of the performance.
Remember that you should let the tapes run to the
end—you should not halt the formatting/recording
process part of the way through the tape.
8.6 Individual clock mode
There are some circumstances where it may be nec-
essary to use independent reference clocks on a chain
of DTRS units when TC time mode (see 9.2, “Tape
timecode mode”) is selected.
There are two settings,
AUTO
and
INDVID
(individ-
ual).
AUTO
is the default, and the unit behaves as fol-
lows when this is selected.
In individual mode, the unit behaves as follows:
1
Press the
SHIFT
key so that the
SHIFT
indicator
is flashing, and press the
MENU
key, until the
counter shows
SYSTEM-- (

2
Press the

briefly shows
CLOk. MODE (

) and
then changes to the current setting.

(INDVID)
modes.
8.7 Error messages
These error messages refer to DTRS
synchronization:
E. DIO (
E DIO
)—appears if the digital cable is not
connected. Re-connect the correct cable to the
DIGITAL I/O
connector.
E. CLOC (
E CLOC
)—appears when the sync cable is
not connected, the master has been turned off, or the
master’s sampling frequency is different from that of
the slave unit’s. Recheck these parameters.
If either of these messages appears, correct the fault
to return to normal operation.
