5 - Basic operations

TASCAM DA-78HR

If you are unsure about the difference between moni-

toring modes as implemented on the DA-78HR, now

is a good time to read 6, “Monitoring”.

Obviously you will want to record while you listen to

the off-tape signals from previously-recorded tracks

and the input source on tracks where recording is tak-

ing place.

5.6 Punch-in and punch-out

There are a number of ways in which the DA-78HR

can be used to perform reliable punch-in and punch-

outs automatically. Punch points can be set and

edited to frame accuracy, either from a cue list or

“on-the-fly” in real time.

The DA-78HR provides a rehearsal mode which sim-

ulates the punching process, allowing the artists to

perfect the timing of the new material.

The mechanics of punching on a digital recorder

appear to the operator to be the same as on an analog

recorder.

Crossfading, however, is an important and useful

function on digital recorders, to ensure continuity

between original and punched material. In the case of

the DA-78HR, this crossfade time is adjustable from

10 milliseconds to 200 milliseconds (7.5, “Crossfade

times”).

The

AUTO MON

mode is essential here: in both

rehearsal and punch modes, the material prior to the

punch point is monitored off tape. The monitoring of

armed tracks changes to source while rehearsals and

punching are carried out and then changes to off-tape

again after the punch-out point See 6, “Monitor-

ing”for details of monitoring modes, including the

AUTO MON

mode.

NOTE

Though it is possible to perform punch recording in

ALL INPUT mode, the monitoring in this mode does

not make it easy to perform accurate punch opera-

tions. We suggest that you turn this mode off when

performing punch-ins.

5.6.1 Automatic punch point setting

Whenever recording takes place, the time when

recording begins is automatically stored as a punch-

in time, and the time when recording stops is stored

as a punch-out time.

This is not usually the way in which you will want to

set the punch points, however. There are several alter-

native ways in which you can set these points, as

described below:

5.6.2 Setting punch points “on the fly”

This method demands sharp reflexes (but you can

edit the punch points later as we show below).

NOTE

If an optional footswitch has been attached to the

rear panel

REMOTE PUNCH IN/OUT

jack

, this

can be used in the following steps instead of the

RECORD

and

PLAY

keys (i.e. press the switch once

to set the punch-in point, and again to set the punch-

out point).

Press the

AUTO MON

key (the indicator will

light).

This is not strictly speaking necessary for set-

ting the punch points, but the

AUTO MON

necessary for punch operations, so we suggest

you turn it on here.

Use the

REC FUNCTION

key(s) to arm the

track(s) on which you will be recording.

Press the

RHSL

(rehearsal) key.

The indicator will flash, showing that the DA-

78HR is in “rehearsal learn” mode.

Rewind the tape to before where the punch is

to occur.

Start playing the tape (press

PLAY

You will monitor the off-tape signals.

At the point where the punch is to occur, press

RECORD

The

RECORD

key will flash, and the

REC

FUNCTION

indicator of any armed tracks will

light steadily. Monitoring will change to input

source recording for these tracks.
