9.4.5 Fast linear timecode (LTC) output

The Fast LTC function controls the way in which

timecode is output when fast winding the tape, or if

shuttling is carried out at greater than normal play-

back speed.

Press the

SHIFT

Use the ▲ and ▼ keys to make the appropriate

setting.

There are three settings:

The

5FRM (

5 FRM

) setting means that timecode

information is not output continuously. Here, the

DA-78HR reads the timecode from the tape as it is

spooling, outputs 5 consecutive frames at normal

speed starting with the value which has been read

from tape, then reads the tape again, outputs another

5 consecutive frames based on the new tape position,

and so on.

The

LEAP (

LEAP

) setting means that timecode is

output continuously during fast operations, and will

not be contiguous (it will leap between frames).

The OFF (

OFF

) setting means that timecode is not

output during fast operations.

9.4.6 Timecode output timing

Because of the nature of the digital-to-analog conver-

sion, the timecode which is output from the DA-

78HR must be synchronized to match the audio tim-

ing from either the digital or the analog audio out-

puts, whichever set of outputs is in use at the time.

9.5 Recording timecode

9.5.1 Selecting the timecode source

The DA-78HR allows you to select one of three

sources for recording timecode: the DA-78HR’s

internal generator, external timecode, or timecode

based on tape.

To select the source for recording timecode:

Press the

SHIFT

key so that the

SHIFT

indicator

is flashing, then press the

key until the

display shows

TCG. REC-- (

SUB MENU

key so that the display

shows

TC. REC. SRC (

) briefly,

and then changes to the current setting.

Use the ▲

and ▼ keys to select a source for the

timecode recording from the following options:

EXT (

EXT

), TCG (

TCG

—timecode generator)

and

TAPE. TC (

TAPE TC

If you select

TAPE. TC, the source of the tape

timecode will be used , as determined in the

tape timecode selection menu (9.2, “Tape time-

code mode”).

NOTE

Generally speaking, timecode should be recorded

from an external source only when audio tracks and

timecode must be transferred together from external

units. In all other cases, we suggest that you use the

internal generator or the tape as sources for record-

ing timecode.
