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 t o pe rf orm relia bl e pu nc h - 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
punc h po int is mo nitored off tape. The moni toring of
armed tracks changes to source while rehearsals and
punchi ng a re ca rr ied out an d the n c hanges to off-ta pe
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 I NPUT mo de, th e m o nitor i ng in t his mod e 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 Automat ic punch po int settin g

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 t ime.
This is not usually the way in wh ich you will want to
set the punch p oints, however. There are several alter-
native ways in which you can set these points, as
described belo w:

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).

can be used in the following steps instead of the

and
PLAY
keys (i.e. press the switch once
to set the punch-in point, and again to set the punch-
out point).
1Press the AUTO M ON key (the indicator will
light).
This is not strictly speaking necessary for set-
ting the punch points, but the AUTO MON is
necessary for punch operations, so we suggest
you turn it on here.
2Use the REC FUNCTION k e y(s) to ar m the
track(s) on which you will be recording.
3Press the RHSL (rehearsal) key.
The indicator will flash, showing that the DA-
78HR is in “rehearsal learn” mode.
4Rewind the tape to before where the punch is
to occur.
5Start playing the tape (press PLAY).
You will monitor the off-tape signals.
6At 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.
