Section 5.1 - Transport controls

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” and 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.

5.1.1Selecting 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.

NOTE

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

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).

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.

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
