5 – Basic DTRS operations

This section covers the basic operations of con-
trolling the DTRS units connected to the RC-898.
For details of how to make parameter settings, etc.
and timecode operations, see 4, “Menu and basic
operations”
, 7, “Making settings on the DTRS
units” an
d 10, “Menu and parameter reference”.

5.1 Transport controls

The transport controls on the RC-898 replicate
those on the DTRS units.

The logic of the transport controls is such that any
mode can be entered from any other mode. There
is no need to go through

STOP

.

5.1.1 Selecting the unit to which

operations refer

Generally speaking, the unit controlled by the
transport keys will be the first unit in the chain
(the other units in the chain are assumed to be
using the ABS chase protocol through DTRS
synchronization.

However, transport operations, etc. can also be
performed on individually-selected machines
other than the first one:

1) Press the

MACHINE

key [31].

The word

MACHINE

will start to flash in the

LOCATE TIME/VALUE

display [15].

2) Use the numeric keypad to enter the

number(one digit only) of the machine that you
want to control .

This number will be shown in the

LOCATE TIME/

VALUE

display [15], and the appropriate

MACHINE

number indicator[8] will light.

If you enter a machine number of 0, this is equiva-
lent to setting all DTRS units except the first into
slave mode, to follow the first unit.

Machine 7 is equivalent to a unit attached to the
parallel port [42], and machine 8 is equivalent to a
unit attached to the serial port [43].

5.1.2 Formatting tapes

The Hi8 tapes used in DTRS units must be for-
matted. This can be done either from the DTRS
units themselves, or from the RC-898.

1) Insert a new tapeor tapes into the DTRS unit

or units. Make sure that it is rewound to the
beginning of the tape.

2) From menu group 9, move the cursor to

Format

, and press

SELECT

:

3) In this menu, as well as using the

NEXT

(

SHIFT

+

UP

) and

PREVIOUS

(

SHIFT

+

DOWN

) keys

to select an individual unit, all DTRS units
connected to the RC-898 can be selected to
format tapes together.

4) Move the cursor to the sampling frequency

field, and use the

UP

and

DOWN

keys to choose

between

44.1

and

48

(kHz).

5) Move the cursor to the “control” field and use

the

UP

key to change the setting from

off

to

ready

6) Press the

UP

key again to change

ready

to

on

.

The FORMAT indicator on each selected DTRS
unit will light.

The three values for this parameter prevent acci-
dental formatting of a tape.

7) Press and hold the

RECORD

key and press the

PLAY

key.

The tape will start to be formatted.

It is possible to record audio and format a tape at
the same time. This is done by arming the tracks
before step 5 above. However, if you do this, you
should not interrupt the formatting process half-
way through a tape. Once you start formatting a

NOTE

Do not use a tape which has previously been used for
recording video.

NOTE

If a digital signal is received at the DIGITAL IN connector
of the DTRS unit, and digital input has been selected (see
7.2.9, “Input selection”)
, the sampling frequency is decided
by the frequency of the incoming signal and cannot be
changed.
